INTRODUCTION

I, Kevin Trenberth, have been retained by Plaintiffs in the above-captioned matter to 

provide expert testimony regarding the impacts of human-caused greenhouse gas emissions 

and climate change on the water cycle and extreme weather events. Below I also discuss the 

role of the atmosphere and oceans, and their interactions.

EXECUTIVE SUMMARY

The climate system consists of the atmosphere, oceans, land and cryosphere. The 

atmosphere is the most volatile component while both atmosphere and oceans are fluids and 

couple together to produce the predominant patterns of variability in the water cycle. We live 

on land, where availability of water depends on rainfall, snow-melt, lakes and rivers, while ice 

is important where it occurs. Weather and climate extremes happen all of the time, even in an 

unchanging climate. Yet these extremes are becoming more frequent and more severe, and the 

primary driver is human-induced climate change. Indeed, the main way in which climate 

change is already affecting, and is likely to continue to affect, human societies around the 

world, is through changes in extreme weather events. Here I summarize the way to think about 

the relationship between our oceans and atmosphere, weather and climate change. I provide my 

expert opinion on how climate change is increasing many extremes, with major consequences 

for human society, including these plaintiffs, and the environment. 

Activities on Earth are adjusted to our current climate, which has been relatively stable 

throughout the past 2,000 years, coinciding with much of the development of human 

civilization. Natural changes in the past have occurred from small variations in the sun and 

effects of volcanic eruptions, and on geological time scales from changes in the Earth’s orbit 

around the sun. Now changes in atmospheric composition from human activities, primarily the 

burning of fossil fuels and deforestation, are the main cause of anthropogenic climate change 

by enhancing the greenhouse effect. Globally, on a day-to-day basis, the effects from these 

human activities are responsible for 1 to 2% of the flow of natural energy through the climate 

system. However, because anthropogenic global warming is always heating the planet, excess 

energy accumulates, and those cumulative effects create a much bigger impact. Importantly, all 

weather events are now occurring in an environment which has changed in significant ways, as 

compared to 50 years ago. The main way this is manifested, the “memory” of these changes, is 

through the accumulated warming of the oceans and the loss of Arctic sea ice. Owing to 

anthropogenic global warming, sea surface temperatures have warmed by over 1°F since the 

1970s, and over the oceans this has led to 5 to 10% more water vapor in the atmosphere. The 

warmer and moister atmosphere in turn has likely led to at least a 5 to 20% effect on storms 

that is greatly exaggerated for extreme weather events. When climate change’s increased effect 

on storms is compounded with natural variations, such as an El Niño event, the effects are 

much larger, and more destructive.

Up until recently, scientists claimed we could not attribute any single weather event to 

global warming (climate change) even though the event was consistent with expectations. The 

reason scientists were reluctant to attribute a single event to global warming is that weather

2

events cannot be predicted more than about 2 weeks in advance, at best. But climate change 

clearly increases the odds of such events occurring. In reality, all weather-related events have 

both natural and anthropogenic components in this era of climate change. When anthropogenic 

climate change and natural climate patterns work synergistically, thresholds are crossed, 

records are broken and it can be said that such extreme events would have been very unlikely 

to occur without global warming. In my expert opinion, if business-as-usual greenhouse gas 

emissions continue, the security and lives of young people and future generations are and will 

be increasingly threatened by ever more extreme weather events than those already being 

experienced. Several of the youth plaintiffs in this case live in regions of the United States that 

have already experienced extreme events compounded by climate change, and are very likely 

to suffer ongoing and increasingly severe extreme events which are made worse by climate 

change.

EXPERT OPINION

1. The climate is changing

Humans have released carbon dioxide and other heat-trapping “greenhouse” gases in 

sufficient quantity to change the composition of the atmosphere, resulting in an accumulation of 

heat in the Earth’s system, commonly referred to as “global warming.” The Earth’s climate has 

responded through higher temperatures in the atmosphere, land and ocean, ice melting, rising sea 

level, and increases in extreme weather events (heat waves, wildfires, heavy rains and flooding).

The calendar year 2016 is by far the warmest on record for the global mean surface temperatures 

(GMSTs) (Figure 1). It easily beat out 2015, which in turn beat out the previous record holder 

2014. Global sea level continues to rise at a rate of over a foot per century (Figure 2). Calendar 

year 2017 continued the record-breaking trend by being the warmest on record for the global 

oceans down to 2,000 m depth (Figure 3) and thus for the planet as a whole, and it was third 

warmest in GMST. Every year since 1997 has been warmer than average in the United States. A 

2018 NOAA report found that the five hottest years in 123 years of record-keeping in the United 

States have all been in the past decade. Also, according to NOAA, five states had their warmest 

years on record, including Arizona, Georgia, New Mexico, North Carolina and South Carolina. 

Alaska had its warmest December ever, with temperatures 15.7°F above its historic average, for 

a statewide average of 19.4°F. There is no doubt whatsoever that the planet is warming and it has 

major consequences for other aspects of our climate. However, there is also a lot of natural 

variability manifested in the GMST record; the biggest fluctuations from year to year are 

associated with El Niño events. 

The USGCRP Climate Science Special Report of 2017 (which I helped the National 

Academy of Sciences peer review), projects with high confidence between 1.6°C and 6.6°C 

(2.8–11.9°F) of warming this century, depending on low or high emissions scenarios, with 

record-setting years becoming the norm and much larger temperature increases by late century. 

The U.S. government has very high confidence that the number of days below freezing will 

continue to decline and the number of days over 90°F will increase.

The overall warming is caused by human activities, mostly through the changes in 

composition of the atmosphere through burning of fossil fuels (industry, electricity generation, 

driving cars, flying airplanes, space heating, etc.), and deforestation. Carbon dioxide 

concentrations in the atmosphere have increased by well over 40% since pre-industrial times (see 

Figure 1) and a key reason is that carbon dioxide has a lifetime of centuries. Air pollution in the 

form of aerosol particulates also plays an important role, but because the particles are washed out 

by rainfall, their average lifetime is on the order of a week. Hence their effects are not global but 

rather regional, and their production has to continue for their effects to be present. Their effects 

are also complex because some reflect the sun and cause cooling, some (carbonaceous) are dark 

and absorb the sun’s rays, and many become involved in clouds and affect the brightness, 

lifetime and disposition of clouds; in general, they cause a cooling effect. In contrast, even if we 

stopped emitting carbon dioxide into the atmosphere today, the elevated concentrations already 

established would persist for some time, thus underscoring the need for urgent reductions in 

carbon dioxide emissions. Hence, changes in atmospheric composition, and particularly the 

increase in carbon dioxide concentrations, enhance the greenhouse effect, although with 

important regional effects from aerosol particulates. As discussed further below, scientists at the 

National Center for Atmospheric Research (NCAR), as well as other scientists around the world, 

Case 6:15-cv-01517-TC Document 267-1 Filed 06/28/18 Page 7 of 111
5

have proven that the global warming is driven primarily from the rise in carbon dioxide by using 

comprehensive climate models, which enable us to also make projections into the future. 

The increased heat-trapping gases in the atmosphere lead to an energy imbalance at the 

top of the atmosphere, and that excess energy is the cause of the warming. Globally on a day-today basis these increased greenhouse gases produce an extra 1 to 2% of the flow of natural 

energy through the climate system. However, because global warming is always heating the 

planet, there is a much bigger impact from the cumulative effects of this added energy. Hence, 

all weather events are now occurring in an environment which has changed in significant ways

as compared to even 50 years ago. Most of the energy imbalance as excess heat, over 91%, ends 

up in the ocean. Hence, the oceans are warmer, Arctic sea ice is melting, and land glaciers and 

ice sheets, such as Greenland, are also melting. The largest temperature rises are occurring in the 

Arctic, where bright reflective snow and ice are melting to reveal dark ocean and land. This 

darkened surface reflects less sunshine, compounding the warming that is causing the melting in 

the first instance. The combination of a warmer ocean that expands, and extra melt-water in the 

oceans means that sea level is rising at a rate of well over a foot per century (Figure 2). Figure 2

shows that sea level is clearly rising as the planet warms. The main fluctuations are associated 

with El Niño when there is more rain over the Pacific Ocean while dips occur in La Niña events 

(such as 2011) when more rain and snow occur over land.

2. How global warming affects extreme events

As well as the overall heating of the planet mainly from human changes in the 

atmospheric composition, which leads to general temperature increases in the atmosphere and 

oceans, and melting ice, there are substantial impacts on extreme events. Indeed, the biggest 

impacts of climate change on society and the environment arise from changes in extremes.

(Figure 4). These are realized through the daily weather systems, which naturally produce 

tremendous variability on all time scales and over many different spatial scales. Hence just by 

chance, extreme values of temperatures, precipitation, or wind, and so forth, occur from vigorous 

weather systems. With global warming, some of these extremes are pushed higher and beyond 

previous values, creating new records. Moreover, global warming often pushes values over 

various thresholds used for design purposes: whether for heat, rain, wind, or sea level, and

accordingly things break. This also means that the events and the new records are episodic. 

There is not a continuous level of high values, rather the values fluctuate substantially as 

they have always done with natural weather patterns. It also means that in one month records are 

broken at one location, while in the next month records break somewhere else, and then 

somewhere else again. The fact that the extremes occur in different places over time, means that 

the public often does not connect them to climate change, and their accumulated effects have 

been greatly underestimated by many. It also means that because of the natural climate 

variability from year to year, it is often difficult to conclusively detect the climate change 

influences––an issue of signal-to-noise, as discussed later.

However, 2017 saw many episodic events setting off-the-charts records with extreme 

wildfires in the western U.S., hurricanes in the southeastern U.S. and the Caribbean, and the 

deadly monsoon flooding in India, Nepal and Bangladesh, all made worse by climate change. 

a. Heat waves

The most obvious expectation is for an increase in short-duration heat waves and their 

impacts as overall temperatures rise.

1 With global warming, often these increasing shortduration heat waves result in temperature rises beyond anything previously experienced in 

 1 Defendants agree that anthropogenic climate change in the United States has produced warmer summers 

and that prolonged heat events in recent years have been the most extreme on record and that climate 

change has contributed to these events (Fed. Answer ¶ 221, 227). They also acknowledge that “[h]eat 

waves would then [if BAU continues] increase in frequency, severity, and duration” (Fed. Answer ¶ 247).

and with (dashed) climate change. From IPCC (2012).

recorded history. This has been borne out in many studies, as documented by Intergovernmental 

Panel on Climate Change (IPCC) reports and other assessments. 

Heat waves nearly always occur in association with a strong slow-moving anticyclone. 

The major European heat wave in the summer of 2003, was one of the first to be well 

documented both in terms of its detection as extremely unusual, and in terms of attribution to 

anthropogenic climate change using climate models. There were major consequences in terms of 

wildfires, and loss of life. A more recent example is the extreme Russian heat wave of 2010, 

again with widespread wildfires, smoke, agricultural losses, and loss of life. Some confusion and 

debate has occurred in the scientific literature about this event over the cause and rarity of the 

weather situation, versus the role of human-induced warming. As discussed in the next section 

on attribution, this confusion arises because the weather events (strong anticyclones) tend to 

occur naturally; while it is the global warming that pushes what would have been an extreme 

event anyway into one that goes well outside previous bounds and causes major strife. After 

analyzing the highest annual temperatures for approximately 9,000 stations globally, we found a

global increase of 0.19°C per decade over the past 50 years (through 2015), which accelerated to 

0.25°C per decade during the last 30 years, a faster increase than in the mean annual temperature. 

Short-term heat waves are increasingly worse with climate change. Other studies have also 

shown that human-caused climate change has increased the severity and probability of the hottest 

days and month of the year by >80%.

High temperatures can result in detrimental health, economic, and social impacts. The 

European 2003 and the Russian 2010 heat waves caused, respectively, almost 70,000 and 55,000 

deaths, while an average of 658 deaths were reported annually during 1999–2009 in the United 

States alone due to excessive heat. Extreme high temperatures cause human casualties in large 

cities and have profound impacts on farms due to reduced crop productivity and adverse effects 

on animals, including mortality. Temperature extremes stress infrastructure, transportation, water 

supply, and electricity demand; severely affect ecosystems and forests, and increase wildfire 

activity. Heat strokes—the most lethal condition of hyperthermia—can be caused by exposure to 

high ambient environmental temperatures. More frequent, more intense, and longer lasting heat 

waves are robustly projected in the 21st Century as a result of human-induced global warming. 

b. Drought and wildfire

In the United States, and indeed in mid-latitude continental areas around the world, there 

is a strong negative correlation between monthly-mean temperatures and precipitation in the 

summer half-year, as there is year-round in the tropics. Heat waves, especially ones of longer 

duration, often occur in association with drought. The anticyclonic conditions that persist in a 

drought situation make for dry settled weather, with little or no precipitation. Under these 

circumstances, the land and vegetation dry out, and the modest extra heat from global warming 

exacerbates the dry conditions. Evaporative cooling ceases as plants wilt, wildfire risk increases, 

and the heat intensifies. That in turn increases the atmospheric demand for moisture, further 

drying out the vegetation in a vicious cycle. 

Case 6:15-cv-01517-TC Document 267-1 Filed 06/28/18 Page 11 of 111

The warmest year on record for the United States as a whole was 2012 when there was a 

widespread drought in association with persistent anticyclonic conditions over much of the 

country. Extreme drought was estimated to cover 39% of the country at its peak in September

2012, rivaling the Dust Bowl years in the early 1930s. According to the Sept. 4, 2012 drought 

monitor, 64% of the country was in moderate to extreme drought. Wildfires became endemic in 

many places, and firefighting costs soared. As a result of these events and the agricultural and 

livestock losses, the net cost has been estimated as over $75 billion, although a partial accounting 

by NOAA lists it as $32 billion. Wildfire Today reports the fire-fighting costs alone in 2012 

were $2 billion.

Perhaps the best example of how climate change can lead to an increase in drought 

conditions is in the West, particularly California. A record-setting drought began in 2012 and 

persisted until 2016 in spite of the big El Niño event (which favors more storms coming into the 

West Coast). It included the lowest annual precipitation on record, the highest annual 

temperature, as well as the most extreme drought indicators ever recorded in California. Along 

with widespread water shortages, the drought brought prolonged and costly wildfires. Indeed, 

wildfires were rampant throughout the West, especially in the summer of 2015, with wildfires 

widespread in Alaska, western Canada, Washington, Oregon and California. In May 2016, a 

major wildfire broke out in Fort McMurray, Alberta following 5 to 8 months of prolonged (El 

Niño related) drought. Major wildfires continued again in August 2016 and July and December

2017 in California, and the consensus has become that the wildfire season in California is now 

almost continuous.

Certain bugs and diseases flourish under these warmer and dryer conditions, such as the 

bark beetle, which is decimating forests across the West. Increased carbon dioxide is not good 

for plants!

c. Storms and precipitation

Perhaps less obvious, but even more dangerous than heat, are the effects of a warming 

planet on the water cycle in which the oceans play a key role (Figure 6). The atmosphere holds

about 4% more moisture per 1°F (or 7% per 1°C) increase in temperature, which leads to 

increased water vapor in the atmosphere, and this provides the biggest influence on precipitation. 

It is undisputed that water vapor is a powerful greenhouse gas, and hence this amplifies the 

original warming substantially. In addition, sea surface temperatures have warmed by more than 

1°F since the 1970s, and over the oceans this has led to 5 to 10% more water vapor in the 

atmosphere. 

Storms, whether individual thunderstorms, extratropical rain or snow storms, or tropical 

cyclones and hurricanes, supplied by increased moisture, produce more intense precipitation 

events, even in places where total precipitation is decreasing. The increased moisture and related 

latent heat release can intensify storms, including hurricanes (next section), and perhaps double2

the original change so that the precipitation increases 5 to 20%. This leads to much stronger and 

more intense rains, and snows, and it increases risk of flooding that exceeds previous bounds for 

extreme weather events. At the same time, dry spells in between such events also increase. 

Indeed, in places where it is not raining, the extra heat dries things out, exacerbating heat waves 

as the evaporative cooling is lost. Hence, droughts set in quicker and become more intense, 

increasing risk of wildfire. This is especially a dangerous problem in the U.S. West, as noted 

above.

Examples are discussed in more detail below. However, in Colorado, the unprecedented 

widespread flooding along the Front Range in September 2013 is a case in point. The moisture 

sources came from very warm ocean regions to the south (the Gulf of Mexico and especially 

from west of Mexico) that undoubtedly had a global warming component. More recently, 

widespread flooding occurred in Missouri (Nov.–Dec. 2015), in Houston in April 2016, in 

Louisiana in August 2016, and in the Carolinas from hurricane Matthew in October 2016. The 

major winter storm “Jonas” that “bombed” Washington D.C. with feet of snow in January 2016 

is another example of such an extreme event. 

In early 2017, in association with unusually high sea temperatures in the subtropical 

North Pacific, the drought in California was abated with heavy rains and snows, leading to 

flooding in many areas. This was a short-lived boon in terms of snowpack to the Sierra Nevadas 

and Rocky Mountains. Meanwhile torrential rains, flooding, mud slides, and loss of life 

occurred in South America: in northern Chile in late February 2017, in Peru in March, and 

Colombia in early April in association with a coastal El Niño that led to very high sea 

temperatures off the Pacific coast in combination with global warming. 

Without climate change, many of these events would have been properly labeled as 

“1000-year events.” However, because of climate change and its effects on the environment, they 

are no longer 1 in 1000-year events, and instead, they are now more likely 1 in 50-year or 100-

year events. They are still uncommon, but not unlikely. The increased flooding from climate 

 2 The effect on the storm depends on where the precipitation and released heat occurs relative to the storm 

center. For hurricanes, the effect is direct and the result can be doubled or more. For extratropical storms 

the effects are more complicated and the effect is a factor of 1 to 2. It varies from storm to storm.

change exposes people in the U.S. to trillions of dollars of damage this century and significant 

human suffering from loss of property and life.

d. Tropical storms and hurricanes

Tropical storms and hurricanes/typhoons mostly occur in the deep tropics in summer in 

association with high sea surface temperatures (SSTs) over 27°C. In turn these reflect high 

ocean heat content (OHC) below the surface and it is this heat energy that is transferred into the 

atmosphere through evaporation, moistening the atmosphere, while evaporative cooling occurs in 

the ocean. The fuel for tropical storms and hurricanes comes from the release of the latent heat in 

heavy rainfall as the moisture is gathered into the storm and condensed. (Figure 7).

One harmful aspect of hurricanes is the fierce winds that cause destruction to people’s 

homes and other buildings and infrastructure. However, hurricanes are also responsible for huge 

storm surges in coastal regions that can be very damaging and are expected to become much 

worse due to both stronger winds and higher sea levels. The most widespread damage, though, 

is actually the flooding from torrential rains that can extend hundreds of miles from the coast.

One major source of variability in tropical SSTs is the El Niño phenomenon that 

produces a warming in the central and eastern Pacific with a corresponding shift in tropical storm 

activity into that region at the expense of other regions. Hurricanes become more frequent in the 

eastern North Pacific but decrease in the Atlantic, for example. Indeed, there is always a 

competition throughout the tropics for where the main activity occurs, and high SSTs are the 

main factor. Once activity is underway in one region of the tropics, it tends to suppress activity 

elsewhere by creating a large overturning circulation in the atmosphere that creates subsiding 

stable air elsewhere and wind-shear in in-between regions (where the low-level winds and upper 

level winds in the troposphere at jet stream level are indifferent directions and/or speeds), and 

this tends to blow a developing vortex apart. Accordingly, tropical storms are clustered and 

cannot occur everywhere at once.

In general, climate warming invigorates tropical storm activity3 by adding energy to the 

storms, but it can be manifested in several ways. With climate change, it is expected that 

hurricanes will become more intense and possibly larger in size and longer lived, but fewer in 

number, as one big storm essentially replaces the effects of several smaller weaker storms in 

terms of the heat energy pulled out of the ocean. Owing to the large natural climate variability 

from year-to-year and unreliable records prior to the satellite era (~1980), it is difficult to clearly 

detect climate change influences on tropical storm activity. “Detection” relies on a climate signal 

that is larger than the noise of natural variability, confounded also in this case by unreliable data. 

So, it is not that there is no signal, but rather that the noise is large. Indeed, there is very 

compelling evidence that there is a climate signal to increased tropical storm activity.

Examples of increased activity are the record-breaking exceptionally large number and 

strength of storms in the Atlantic in 2005, super storm Sandy on the East Coast in 2012, the 

strongest land-falling typhoon on record: Haiyan in 2013 that went through the Philippines, and 

the very strong storms recorded in several regions in 2015 and 2016 (strongest in the southern 

Hemisphere––Winston in 2016 that went through Fiji). The year 2015 is the most active year 

globally for hurricanes/typhoons ever. The latter is in part because it was an El Niño year, but it 

highlights the fact that high sea surface temperatures for whatever reason produce bigger and 

stronger storms. At the same time, there are quiet years, that highlight the large variability. 

 3Because a warmer atmosphere holds more moisture, there will be an increase in heavy precipitation, and 

related flooding, from tropical storms and hurricanes. Moreover, because tropical storms and hurricanes 

are now occurring in the context of sea level rise, the storm surges are greater and more destructive than 

they were when sea levels were lower (see discussion of Super Storm Sandy in Section 3(b) below). For 

example, Defendants agree that rising relative sea levels have caused increased flooding in many 

communities (Fed. Answer ¶ 218). Defendants in this case also agree, for instance, that climate change is 

associated with increases in hurricane intensity, increased frequency of intense storms and heavy 

precipitation, and that the number of very heavy precipitation events has been significantly above average 

since 1991 (Fed. Answer ¶ 220).

In the Atlantic, following the record-breaking active years of 2004 and 2005, the tropical 

storms were less active, until 2017. Hurricanes Harvey, Irma, and Maria were very strong, huge 

and long-lived and did well over $250 billion in damage to Texas, Florida, Puerto Rico and many 

Caribbean Islands. Atlantic hurricanes are normal events in summer, with an average of 12 

named storms and 6 hurricanes in the Atlantic. However, in 2017 there were 17 named storms 

and 10 hurricanes, 6 of which were categorized as “Major.” According to National Oceanic and 

Atmospheric Administration (NOAA), the Accumulated Cyclone Energy (ACE) was 225% of 

normal. Harvey’s record-shattering rainfall featured several locations with over 60 inches (1,500 

mm) and a study has shown how the probability of exceptionally high rainfalls in Harvey-like 

storms has increased because of climate change. Another study used an extreme value analysis to 

show that climate change had increased Harvey precipitation over land by about 37.7%, as a best 

estimate. The extremely high rainfalls have been linked to the record high ocean heat content in 

the Gulf prior to the storm. 

Our oceans serve as the memory of the accumulated human-induced global warming 

(Figure 3). The higher ocean heat content and sea surface temperatures invigorate tropical 

cyclones to make them bigger, more intense and longer lasting, leading to more destructive rains 

and flooding. Hurricanes cool tropical oceans through their strong winds and increased 

evaporation. The evidence strongly suggests that these 2017 storms would not have happened 

with as much rainfall and intensity, and resulting damage, without climate change. MichelKergan and Kunreuther (2011) discuss the costs of flooding and conclude that hurricanes 

Katrina, Rita and Wilma in 2005 cost over $180 billion (2011 prices); and they also assign costs 

to several other events. 

e. Snowfall and snow cover

In winter over the northern hemisphere land, the snow season is getting shorter at each 

end as more precipitation arrives as rain.

4 Generally, the biggest snowfall occurs with 

temperatures just below freezing, and hence in mid-winter, the prospects, as observed, are for 

bigger snowfalls and larger snow pack from November through January. With climate change, it 

is no longer “too cold to snow” very often. In contrast, snow pack is observed to be much 

reduced across the northern hemisphere from March through August 1966 to 2014. Due to global 

warming, snow melt starts sooner, runoff occurs sooner in the spring, and the risk of drought and 

water shortages are greater in summer, along with wildfire, and insect pest infestations. 

3. Attribution 

Scientists are working to attribute causes to weather and climate events, which is often 

challenging from a physical standpoint. Owing to the chaotic nature of the atmospheric 

circulation (often depicted by the flap of a butterfly’s wings changing the future weather), the 

detailed day-to-day weather cannot be forecast more than about two weeks into the future. Many 

repeated computer runs with small perturbations in initial states (forming ensembles) are used to 

bring out the robust features in future predictions versus those that depend on unknown details. 

 4 Defendants have acknowledged that “[b]y 2050, snowmelt is projected to shift three to four weeks 

earlier than the 20th century average.” (Fed. Answer ¶ 249).

Case 6:15-cv-01517-TC Document 267-1 Filed 06/28/18 Page 17 of 111
15

This is done even for 2-week weather forecasts and is essential for climate simulations and 

predictions. In dealing with climate predictions, then, the goal is not to predict the detailed 

evolution but the general patterns of weather, such as those that occur from one season to the 

next. Hence the reason scientists are reluctant to attribute a single event to global warming is 

that weather events cannot be predicted more than about 2 weeks, but climate change may 

change the odds of such events occurring.

The climate science community has responded to the demand for timely information by 

attempting to perform attribution of climate extremes. The dissemination of attribution has been 

partly through the IPCC5 reports, but also through annual reports offering closer to real-time 

assessments and posing the question of whether the likelihood or strength of the event was 

affected by anthropogenic climate change. Increasingly, some reports are issued in near real 

time, but often with compromises as to what can be done.

More generally, there are perhaps two main kinds of attribution analyses performed, what 

I call the conventional approach and the conditional approach. The first relates the particular 

extreme event to the associated weather and weather patterns with statements such as ‘the 

drought was caused by a blocking anticyclone’; ‘the outbreak of tornadoes was caused by a 

displaced and active storm track and jet stream.’ Although useful, these phenomena are really a 

description of the event, not a cause. Importantly, this approach does not ask the questions: ‘Why 

did that weather phenomenon behave the way it did?’ In particular, ‘What influences external to 

the atmosphere were playing a role, and what climate factors were in play?’ 

The second kind of attribution study, the conditional approach, relates to the objective of 

assessing the role of human activities, and especially of human-induced climate change, in the 

event. Results depend, however, upon how the questions are framed.

The conventional approach assesses how the weather system might have changed from 

climate change influences; it requires many climate model runs with and without climate change 

present to sort out how unusual the weather event was and how the odds were changed by 

climate change. Because of the infinite natural variety of weather and the often-uncertain nature 

of the human influences, such changes are mostly very small and lost in the noise. The huge 

 5 The IPCC is a body of scientists from around the world convened by the United Nations jointly under 

the United Nations Environment Programme (UNEP) and the World Meteorological Organization 

(WMO) and initiated in 1988 under the leadership of the United States. Its mandate is to provide policy 

makers with an objective assessment of the scientific and technical information available about climate 

change, its environmental and socio-economic impacts, and possible response options. The IPCC reports 

on the science of global climate and the effects of human activities on climate in particular. Major 

assessments were made in 1990, 1995, 2001, 2007, and 2013. Each new IPCC report reviews all the 

published literature over the previous 5 to 7 years, and assesses the state of knowledge, while trying to 

reconcile disparate claims and resolve discrepancies, and document uncertainties. The IPCC perhaps 

represents the scientific consensus, but precisely because it is a consensus assessment among very 

disparate scientists from many countries with varying expertise, it is extremely conservative and lags 

behind the state-of-the-art scientific understanding. The IPCC format has always created certain 

difficulties because of the huge numbers of scientists involved whose contributions are voluntary. The 

many chapters are written by teams in parallel, and the three Working Groups mostly work in parallel. 

The timeline for a report is several years and, because it is thoroughly reviewed, it is not current at time of 

publication. This has led to calls for a more operational and timely assessment process.

computational demand precludes the near real-time commentary required by the media. Instead,

it is more useful to regard the extreme circulation regime or weather event as being secondary––

it is the means whereby the event happens––and instead focus on the effects of the wellestablished changes in the environment from global warming on the impacts of the particular 

event. The conventional attribution framework struggles with dynamically-driven extremes 

where the weather system itself plays a major role because the natural variability of weather is so 

large, and hence there are small signal-to-noise ratios. Moreover, the expected changes in 

weather systems (from climate models) are often highly uncertain. It is better to examine 

whether known changes in the climate system’s thermodynamic state (i.e. temperature related) 

affected the impact of the particular event. Because the water-holding capacity of the 

atmosphere depends strongly on temperature – it increases 7% per °C––there is also a direct 

relationship with humidity and precipitation. The National Academy of Sciences “Attribution of 

Extreme Weather Events in the Context of Climate Change” in March 2016, presented both 

approaches as two aspects of the same spectrum, virtually without comment. But the message 

was that the strongly conditioned approach is completely acceptable, and moreover that the 

traditional approach will be limited by adequacy of the modeling tools available. In particular, 

as the consideration turns from extremes such as heat waves to extreme precipitation and storms, 

useful statements are much more likely from the strongly conditioned approach.

In the past, the conventional way of approaching attribution tried to deal with all aspects 

of the problem. But the changes in weather phenomena and weather systems, where they go, and 

so forth have infinite variety (called weather) and any climate change signal is small (except in 

the case of the ozone hole). This has confounded the results. In particular, the conventional 

approach to attribution of climate events is to characterize the event and ask (i) whether the 

likelihood or strength of such events has changed in the observational record, and (ii) whether 

this change is consistent with the anthropogenic influence as found in one or more climate 

models. This approach has had considerable success with extremes that are strongly governed by 

thermodynamic aspects of climate change, especially those related to temperature, each finding 

providing another independent line of evidence that anthropogenic climate change is affecting 

climate extremes.

The conventional approach, however, is severely challenged when evaluating climate 

extremes that are strongly governed by atmospheric circulation, including local aspects of 

precipitation.It isinherently conservative and prone to false negatives, which underestimate the 

true likelihood of the human influence. This is all the more reason why the more recently 

developed “conditional” approach provides more insight and illumination as to what is truly 

going on and the role of climate change.

a. More fruitful scientific questions: the conditional approach

Because of the infinite variety of weather systems and how rapidly they develop and 

respond to small perturbations, the atmospheric circulation (dynamics) aspects of climate change 

are much less predictable than those associated with heat and temperature (thermodynamics). 

Hence separating out the thermodynamic from dynamic effects in extreme events, i.e., the 

conditional approach, is a new fruitful way forward in evaluating attribution and results in a 

different set of questions to be addressed than in the past (prior to 2015): 

Case 6:15-cv-01517-TC Document 267-1 Filed 06/28/18 Page 19 of 111
17

• Given the weather pattern, how were the temperatures, precipitation and associated 

impacts influenced by climate change?

• Given a drought, how was the drying (evapotranspiration) enhanced by climate change, 

and how did that influence the moisture deficits and dryness of soils, and the wildfire risk? 

Did it lead to a more intense and perhaps longer-lasting drought, as is likely?

• Given a flood, where did the moisture come from? Was it enhanced by high ocean 

temperatures that might have had a climate change component?

• Given a heat wave, how was that influenced by drought, changes in precipitation 

(absence of evaporative cooling from dry land) and extra heat from global warming?

• Given extreme snow, where did the moisture come from? Was it related to higher than 

normal SSTs off the coast or farther afield? 

• Given an extreme storm, how was it influenced by anomalous SSTs and OHC, 

anomalous moisture transports into the storm, and associated rainfall and latent heating? Was 

the storm surge worse because of high sea levels?

In other words, given the change in atmospheric circulation that brought about the event, how 

did climate change alter its impacts? 

Therefore, a fruitful and robust approach to climate extreme-event attribution is to regard 

the circulation regime or weather event as a conditional state (whose change in likelihood is not 

assessed), and ask whether the impact of the particular event was affected by known changes in 

the climate system’s thermodynamic state (for example sea level, sea surface temperature or 

atmospheric moisture content), concerning which there is a reasonably high level of confidence. 

The consequences of climate change are that things dry out quicker (stronger longer 

droughts) ––as the atmosphere demands more evaporative moisture––and the extra moisture 

means heavier rains and greater risk of flooding elsewhere, so that ironically, the risk of both 

extremes of the hydrological cycle are substantially increased.

This is confusing to many people, but of course the floods and droughts occur at different 

times or even different years, and different places at the same time. Those studies that have 

sought to understand this through changes in the weather patterns have generally failed and

concluded that natural variability rules. But, as explained above, the weather patterns occur in a 

different environment, one that is warmer and moister and thus one where the atmosphere 

demands more moisture and causes drying where it is not raining, but one that provides much 

more moisture to storms with resulting much heavier rains, or even snows, where it is 

precipitating. 

Of course, there are some observed changes in weather patterns, most notably in the 

southern hemisphere in association with the ozone hole, and small changes elsewhere are 

projected in the future. In addition, some changes have apparently occurred in association with 

decadal variability (e.g., related to the pause in the rise of GMST from 2000 to 2013) to further 

confound results. The main data available to study circulation changes begin in 1979, and the 

strong Pacific Decadal Oscillation pattern in its negative phase from 1999 through 2013, 

associated with the slow-down in the rise in GMST, has led to published claims of such changes,

but they are flawed as the signal is not that of climate change. This confusion has also been 

apparent in IPCC reports and national assessments. Below I provide some examples where the 

thermodynamic aspects are emphasized to bring out the human influence.

b. Examples

Super Typhoon Haiyan/Yolanda, November 

2013: the strongest recorded storm ever to 

reach land. (Figure 8). The OHC and sea level 

in the Philippines’ region had both increased a 

great deal since 1993 and especially since 1998.

Consequently, as Typhoon Haiyan approached 

the Philippines, it was riding on very high SSTs 

with very deep support through the high OHC. 

The strong winds and resulting ocean mixing 

did not cause as much cooling as would 

normally be experienced, helping the storm to 

maintain its tremendous strength. 

Moreover, the storm surge was 

undoubtedly exacerbated considerably by the 

sea levels, which were some 30 cm (1 foot) 

above 1993 values. Although natural variability 

played an important role, increased OHC from 

the Earth’s energy imbalance (climate change) 

made the typhoon more intense and bigger.

Super storm Sandy. Super storm Sandy

(Figure 9) struck the Northeast in late October 

2012 and devastated the Jersey Shore and 

parts of New York City, including flooding 

the subway and tunnels to Brooklyn and New 

Jersey, and 233 lives were lost. Munich Re 

puts the cost of the storm surge at US $68.4

billion although other estimates are higher. 

Because the storm was very well predicted a 

week ahead of time by sophisticated 

numerical weather prediction models, it was 

possible to run many computer-based forecasts 

with observed SSTs versus those with 

climatological conditions, that showed almost 

no effects on the track of the storm, but large and significant effects for intensity, wind strength 

and size. Hence Sandy was undoubtedly larger and stronger as a result of climate change, and 

the storm surge was much greater owing to high sea levels and stronger winds. It is quite likely

that the subways and tunnels in and around New York would not have flooded without the 

warming-induced increases in sea level and in storm intensity and size. 

This is an excellent example of thresholds being crossed with highly nonlinear 

consequences. Relatively small increases in water from the climate change component caused 

billions of dollars in damage. For example, on 14 Nov. 2012 the New York Times editorial 

“Money to rebuild after Sandy” reported that “New York, New Jersey and Connecticut — the 

states hit hardest by Hurricane Sandy — will need tens of billions of federal dollars to repair 

bridges, tunnels, subway and commuter rail lines, rebuild schools, power stations and homes,

and pay off staggering amounts of overtime” and noted the 

request from Mr. Cuomo (the Governor) for $30 billion.

California drought, 2013–16. (Figure 10). One study of the 

recent California drought that focused on atmospheric 

circulation effects found no significant trends in winter 

precipitation in recent decades while another pointed out the 

critical role of the record high annual mean temperatures in 

combination with record low annual precipitation for 2013,

which led to increased evapotranspiration and more intense 

drought. Another study suggested between 8 and 27% of the 

warming contributing to the drought was anthropogenic, but 

even this is likely an underestimate as it used inadequate 

models and did not account for the changing snowpack. The 

combination of the weather pattern and climate change had 

impacts on water shortages, vegetation and agriculture, and 

increased wildfire risk. 

The odds of this combination of events have increased 

with human-induced climate change and anthropogenic 

warming causing increased risk of drought and heat waves. 

Again, several studies are consistent with the view that the 

atmospheric circulation changes are not the dominant factor, 

as they arise mostly from natural reasons, while climate 

change greatly increases heat and drying under favorable 

conditions and thus increases the impacts.

Colorado Floods, September 2013. (Figure 11). In Colorado, 

the unprecedented heavy rains (over 9 inches in 24 hours, over 

17 inches in several locations from 9 to 15 September) led to 

widespread flooding along the Front Range caused widespread 

devastation, with 345 homes lost and over 550 more damaged. 

The unusual tropical moisture sources came from very warm 

ocean regions to the south (the Gulf of Mexico and especially 

from west of Mexico), where twin hurricanes Manuel 

and Ingrid formed as soon as the moisture flow to the 

north was cut off and the double strike in Mexico led to 

192 deaths and nearly $6 billion in damage. The 

exceptionally high SSTs at the time of the Colorado 

floods in the absence of an El Niño undoubtedly had a 

global warming component.

of Mexico and in the subtropical North Atlantic. The moisture was transported into the region of 

the flooding by the storms and resulted in unprecedented rains and flooding. By one very 

credible estimate, climate change increased the chance of the 3-day torrential rains in south 

Louisiana by over 40 percent. The impacts were profound. 

These events highlight that it is the combination of natural variability (weather, El Niño 

etc.) and climate change, when they go in the same direction that causes records to be 

broken. Hence there are more extreme climate events of all sorts. The result is huge both in 

terms of economic loss and human suffering.

c. Harm and risks to the youth plaintiffs

Several of the youth Plaintiffs have been harmed by the extreme weather events I 

mention above. Extreme events like those described above will increasingly threaten these youth, 

and indeed all of the next generation.

a. Plaintiff Jayden lives in Rayne (just west of 

Lafayette), Louisiana, outside of what was 

determined to be the floodplain. However, during 

the extreme storms and flooding in August 2016 and 

again in May 2017, Jayden’s home experienced 

flooding. The August flooding destroyed much of 

Jayden’s home, her room included, and she had been 

forced to sleep with her siblings in their living room. 

Just two months before the May floods Jayden had 

moved back into her room for the first time. While 

the May floods were not as destructive, it did cause 

cracks in the foundation of Jayden’s house and 

flooding in the hallways. As noted above, these 

“Louisiana floods” resulted from record-breaking 

amounts of water vapor gathered by the storms and 

dumped on the region. The magnitude of the 

rainfalls and the extent of the flooding near Jayden’s 

home would not have occurred without the humaninduced climate change. (Figure 13).

b. Plaintiff Levi was forced to evacuate his home and his island when Hurricane Matthew

threatened and eventually struck the east coast in October 2016 and again when Hurricane Irma 

struck Florida in October 2017. While Levi was away from his home in 2016, it was flooded 

with around 1 inch of water and a neighbor’s home had burned to the ground when a downed 

powerline started a fire. The Hurricane caused significant erosion and accumulation of debris on 

the beaches Levi visits. Once again, record-breaking amounts of water vapor were gathered by 

the storms and the magnitude of the rainfalls and the extent of the flooding near Levi’s home 

would not have occurred without the human-induced climate change. (Figure 12).

floods of 11-13 August 2016, from NOAA.

c. Plaintiff Xiuhtezcatl, in Boulder CO, lived 

through the Colorado floods in September 2013, as my 

family did. Several people were killed. Record 

breaking rain amounts occurred over several days. The 

damage was widespread and recovery is still underway. 

As explained above, human-induced climate change 

played a role in enhancing the rains and flooding.

(Figure 14).

d. Plaintiff Journey in Kauai is threatened by 

extreme storm events. In 2015 an unprecedented 

number of hurricanes threatened the Hawaiian Islands, 

again enhanced by human-induced climate change.

(Figure 15).

e. Plaintiff Victoria, White Plains, NY lived 

through Super storm Sandy in New York. Many people 

died and many were evacuated for over a week 

(including my wife and daughter and family who were in 

Hoboken, NJ), with great cost and human suffering.

Super storm Sandy was bigger and stronger, and impacts 

were much worse because of human-induced climate 

change. (Figure 16).

f. Plantiff Jacob, Roseburg, Oregon, lives on a 

farm and enjoys the outdoors. He has become very 

concerned and influenced by the expanding wildfire 

season, especially in 2015, when smoke degraded the air 

quality on many days. The wildfire season has become 

longer and more intense due to human-induced climate 

change. (Figure 17).

g. Plaintiff Jaime from Cameron, AZ, has 

experienced water shortages related to increasing 

significant drought, wildfires and heat waves. Wildfires, 

drought and heatwaves have increased in the area of 

Jaime’s home and reservation because of human-induced 

climate change. (Figure 17).

h. Plaintiff Zealand lives in Eugene, 

OR and has had to be evacuated from the 

backcountry due to wildfire. In the fall of

2017 Zealand suffered another loss when his 

grandmother’s trailer park in Santa Rosa 

burned to the ground during one of the 

wildfires that blazed through California (as 

part of what is known as the extremely 

destructive Tubbs fire). Global warming 

directly contributes to increased risk of 

wildfire. (Figures 17 and 18).

i. Plaintiff Nathan has experienced

thawing permafrost and wildfires around his 

home in Fairbanks, Alaska, especially in 

2015. Thawing permafrost is uneven and 

more likely on sunlight slopes, and has led to 

tilted and broken buildings and frost heaves 

in roads. Wildfires were widespread in 

Alaska in the summer of 2015. These harms 

are made worse by human-induced climate 

change. (Figure 19).

4. Conclusions and Recommendations

Based on over 40 years of 

experience, it is my expert opinion that 

Plaintiffs including Jayden, Levi, 

Xiuhtezcatl, Victoria, Jaime, Journey, 

Zealand, and Nathan are already 

experiencing extreme weather events that 

have been exacerbated due to 

anthropogenic climate change. 

Furthermore, based on the regions 

where they live, it is my expert opinion that 

they are likely to experience even greater 

impacts from extreme weather events in the 

coming decades. 

A summary of the way human 

influences affect storms and precipitation is 

given in Figure 7.

There are increasing numbers of 

billion dollar disasters in the U.S. and 

around the world. In the U.S. in the past 20 

years there has been on average over $42 

billion in weather-related disaster costs, 

according to NOAA. Figure 20 shows 

numbers worldwide from Munich Re for 

1980 through 2016 (based on data 

downloaded 4 July 2017) along with the 

contributions from weather and climaterelated events in billions of U.S. $. A lot of 

this depends on where the disaster happens 

and how much infrastructure is present, and 

it does not measure the human factors, such 

as strife and loss of life, especially in 

developing countries.

Of course, extreme weather has 

always happened, but now thresholds are 

being crossed, records broken, and so at 

least a portion of these losses can be 

ascribed to climate change. There is no 

precise tool for how much should be 

ascribed to human influences. On the one 

hand, records can be broken even without 

climate change. At the very least, the 

storm, precipitation and weather-related

events are amplified by water vapor increases of 5 to 10% since 1970, and these lead to 5 to 20% 

increases in precipitation intensity, or more. But it is not appropriate to then assign only 5 to 

20% of the cost of the disaster to human-induced climate change because the damage is highly 

nonlinear. Once thresholds are crossed, things break, burn or die!

In my expert opinion, it is generally accurate to say that extreme events, which break 

records and cross thresholds, would not have happened without global warming, because 

otherwise the event would have been well within previous experience. Thus, thresholds are 

crossed and records are broken because of anthropogenic climate change. Moreover, every event 

is different. Events occur in different places and evolve very differently, whether floods, 

wildfires, or heat waves, but they all have one aspect in common, they would not have been as 

severe without the human influence. In light of this, one could argue that the whole cost might 

be assigned to climate change. Certainly, a very good case can be made that damages due to 

climate change are likely already well over $10 billion per year.

Hence the increased ocean temperatures and the increased water vapor in the atmosphere 

have led to changes in extremes, which have huge impacts on society and on ecosystems and the 

environment. Thus, climate extremes exacerbated by human-induced climate change already 

pose a serious risk of harm to people’s lives, personal security, and property in new ways. The 

causes of the global warming are clear and future projections are for more of the same but with 

increasing magnitude. What are extreme and unusual events now, boosted by the right kind of 

circumstances (weather system), will become commonplace in a decade or two. Without 

immediate reductions in fossil fuel emissions, farming may become difficult unless major 

evolution occurs (different crops), and by mid-century many trees and ecosystems will no longer 

be viable where they currently stand.

The atmosphere is global; we share these problems with other nations, although when 

considering cumulative emissions, the U.S. has been the biggest contributor by far. As scientists, 

we can lay out the facts and evidence, and the prospects, but fully addressing climate change

requires government leadership. 

The costs of the increased frequency and destructiveness of extreme weather events are 

not borne by those who cause the problem. There is still time to manage the problem and avoid 

the worst possible outcomes, and there can be major economic advantages as well greater energy 

efficiency when transitioning off fossil fuels. It does not have to cost more if done in the right 

way. 

These youth Plaintiffs and future generations will continue to live with even more 

extreme weather events, which will threaten their personal security, property, and lives. 

However, swift action to reduce emissions and transition off of fossil fuels can slow and 

eventually stop further damage to the climate system and water cycle. Therefore, in my expert 

opinion, the federal defendants in this action should be required to swiftly decarbonize the U.S. 

energy system, as an essential step to protect children and future generations from the real 

dangers posed by human-induced climate change. We are all together on this spaceship Earth.

What the U.S. government does with our national energy system and emissions matters 

immensely to our ability to preserve a livable climate for our posterity.
