Query: ’Extremely remarkable’ 2017 heads toward record for hottest year without an El Niño episode.

Relevant passages:
El Niño <=SEP=> El Niño -LSB- ɛl_ˈniːnjoʊ -RSB- ( -LSB- el ˈniɲo -RSB- ) is the warm phase of the El Niño Southern Oscillation ( commonly called ENSO ) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific ( between approximately the International Date Line and 120 ° W ) , including off the Pacific coast of South America . El Niño Southern Oscillation refers to the cycle of warm and cold temperatures , as measured by sea surface temperature , SST , of the tropical central and eastern Pacific Ocean . El Niño is accompanied by high air pressure in the western Pacific and low air pressure in the eastern Pacific . The cool phase of ENSO is called `` La Niña '' with SST in the eastern Pacific below average and air pressures high in the eastern and low in western Pacific . The ENSO cycle , both El Niño and La Niña , cause global changes of both temperatures and rainfall .   Developing countries that are dependent upon agriculture and fishing , particularly those bordering the Pacific Ocean , are usually most affected . In American Spanish , the capitalized term `` El Niño '' refers to `` the little boy '' , so named because the pool of warm water in the Pacific near South America is often at its warmest around Christmas . The original name , `` El Niño de Navidad '' , traces its origin centuries back to Peruvian fisherman , who named the weather phenomenon in reference to the newborn Christ . `` La Niña '' , chosen as the ` opposite ' of El Niño , literally translates to `` the little girl '' .

La Niña <=SEP=> La Niña ( -LSB- lɑːˈniːnjə -RSB- , -LSB- la ˈniɲa -RSB- ) is a coupled ocean-atmosphere phenomenon that is the counterpart of El Niño as part of the broader El Niño -- Southern Oscillation climate pattern . The name La Niña originates from Spanish , meaning `` the little girl '' , analogous to El Niño meaning `` the little boy '' . It has also in the past been called anti-El Niño , and El Viejo ( meaning `` the old man '' ) . During a period of La Niña , the sea surface temperature across the equatorial Eastern Central Pacific Ocean will be lower than normal by 3 to 5 ° C . In the United States , an appearance of La Niña persists for at least five months . It has extensive effects on the weather in North America , even affecting the Atlantic Hurricane Season .

Instrumental temperature record <=SEP=> The instrumental temperature record provides the temperature of Earth 's climate system from the historical network of in situ measurements of surface air temperatures and ocean surface temperatures . Data are collected at thousands of meteorological stations , buoys and ships around the globe . The longest-running temperature record is the Central England temperature data series , that starts in 1659 . The longest-running quasi-global record starts in 1850 . In recent decades more extensive sampling of ocean temperatures at various depths have begun allowing estimates of ocean heat content but these do not form part of the global surface temperature datasets .
Query: So it’s been a surprise to climate scientists that 2017 has been so remarkably warm — because the last El Niño ended a year ago.

2014–16 El Niño event <=SEP=> The 2014 -- 16 El Niño was a warming of the eastern equatorial Pacific Ocean that resulted in unusually warm waters developing between the coast of South America and the International Date Line . These unusually warm waters influenced the world 's weather in a number of ways , which in turn significantly affected various parts of the world . These included drought conditions in Venezuela , Australia and a number of Pacific islands while significant flooding was also recorded . During the event more tropical cyclones than normal occurred within the Pacific Ocean , while fewer than normal occurred in the Atlantic Ocean .
Query: Which means that if the planet is five degrees warmer at the end of the century, we may have as many as 50 percent more people to feed and 50 percent less grain to give them.”

Relevant passages:
Human overpopulation <=SEP=> Human overpopulation occurs when the ecological footprint of a human population in a specific geographical location exceeds the carrying capacity of the place occupied by that group . Overpopulation can further be viewed , in a long term perspective , as existing when a population can not be maintained given the rapid depletion of non-renewable resources or given the degradation of the capacity of the environment to give support to the population .   The term human overpopulation refers to the relationship between the entire human population and its environment : the Earth , or to smaller geographical areas such as countries . Overpopulation can result from an increase in births , a decline in mortality rates , an increase in immigration , or an unsustainable biome and depletion of resources . It is possible for very sparsely populated areas to be overpopulated if the area has a meagre or non-existent capability to sustain life ( e.g. a desert ) . Advocates of population moderation cite issues like quality of life , carrying capacity , and risk of starvation as a basis to argue against continuing high human population growth and for population decline . Scientists suggest that the human impact on the environment as a result of overpopulation , profligate consumption and proliferation of technology has pushed the planet into a new geological epoch known as the Anthropocene .
Query: In Alaska, already, researchers have discovered remnants of the 1918 flu that infected as many as 500 million and killed as many as 100 million”

Relevant passages:
Spanish flu <=SEP=> The Spanish flu, also known as the 1918 flu pandemic, was an unusually deadly influenza pandemic caused by the H1N1 influenza A virus. Lasting from February 1918 to April 1920, it infected 500 million people – about a third of the world's population at the time – in four successive waves. The death toll is typically estimated to have been somewhere between 17 million and 50 million, and possibly as high as 100 million, making it one of the deadliest pandemics in human history. The first observations of illness and mortality were documented in the United States (in Kansas and New York City, and months before, in December 1917, at Camp Greene, North Carolina), France, Germany, and the United Kingdom. To maintain morale, World War I censors minimized these early reports. Newspapers were free to report the epidemic's effects in neutral Spain, such as the grave illness of King Alfonso XIII, and these stories created a false impression of Spain as especially hard hit. This gave rise to the name "Spanish" flu. Historical and epidemiological data are inadequate to identify with certainty the pandemic's geographic origin, with varying views as to its location.
Query: According to the WHO, exposure to particulate matter increases the risk of acute lower respiratory infection, chronic obstructive pulmonary disease, heart disease, stroke and lung cancer.

Air pollution <=SEP=> Air pollution occurs when harmful substances including particulates and biological molecules are introduced into Earth 's atmosphere . It may cause diseases , allergies or death in humans ; it may also cause harm to other living organisms such as animals and food crops , and may damage the natural or built environment . Human activity and natural processes can both generate air pollution .   Indoor air pollution and poor urban air quality are listed as two of the world 's worst toxic pollution problems in the 2008 Blacksmith Institute World 's Worst Polluted Places report . According to the 2014 WHO report , air pollution in 2012 caused the deaths of around 7 million people worldwide , an estimate roughly matched by the International Energy Agency .

Particulates <=SEP=> Atmospheric particulate matter -- also known as particulate matter ( PM ) or particulates -- are microscopic solid or liquid matter suspended in the Earth 's atmosphere . The term aerosol commonly refers to the particulate/air mixture , as opposed to the particulate matter alone . Sources of particulate matter can be man-made or natural . They have impacts on climate and precipitation that adversely affect human health .   Subtypes of atmospheric particulate matter include suspended particulate matter ( SPM ) , thoracic and respirable particles , inhalable coarse particles , which are -LSB- coarse -RSB- particles with a diameter between 2.5 and 10 micrometers ( μm ) ( PM10 ) , fine particles with a diameter of 2.5 μm or less ( PM2 .5 ) , ultrafine particles , and soot   The IARC and WHO designate airborne particulates a Group 1 carcinogen . Particulates are the deadliest form of air pollution due to their ability to penetrate deep into the lungs and blood streams unfiltered , causing permanent DNA mutations , heart attacks , and premature death . In 2013 , a study involving 312,944 people in nine European countries revealed that there was no safe level of particulates and that for every increase of 10 μg / m3 in PM10 , the lung cancer rate rose 22 % . The smaller PM2 .5 were particularly deadly , with a 36 % increase in lung cancer per 10 μg / m3 as it can penetrate deeper into the lungs .

Tundra <=SEP=> In physical geography , tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons . The term tundra comes through Russian тундра ( tûndra ) from the Kildin Sami word tūndâr `` uplands '' , `` treeless mountain tract '' . There are three types of tundra : Arctic tundra , alpine tundra , and Antarctic tundra . In tundra , the vegetation is composed of dwarf shrubs , sedges and grasses , mosses , and lichens . Scattered trees grow in some tundra regions . The ecotone ( or ecological boundary region ) between the tundra and the forest is known as the tree line or timberline .

Permafrost <=SEP=> In geology , permafrost is ground , including rock or ( cryotic ) soil , at or below the freezing point of water 0 C for two or more years . Most permafrost is located in high latitudes ( in and around the Arctic and Antarctic regions ) , but alpine permafrost may exist at high altitudes in much lower latitudes . Ground ice is not always present , as may be in the case of nonporous bedrock , but it frequently occurs and it may be in amounts exceeding the potential hydraulic saturation of the ground material . Permafrost accounts for 0.022 % of total water on earth and exists in 24 % of exposed land in the Northern Hemisphere . It also occurs subsea on the continental shelves of the continents surrounding the Arctic Ocean , portions of which were exposed during the last glacial period , with global weather implications .   A global temperature rise of 1.5 C-change above current levels would be enough to start the thawing of permafrost in Siberia , according to one group of scientists .
Query: He said: ‘We have had five warming cycles since about 900AD, each followed by a dramatic cooling cycle.’

Relevant passages:
Ice age <=SEP=> An ice age is a period of long-term reduction in the temperature of Earth 's surface and atmosphere , resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers . Within a long-term ice age , individual pulses of cold climate are termed `` glacial periods '' ( or alternatively `` glacials '' or `` glaciations '' or colloquially as `` ice age '' ) , and intermittent warm periods are called `` interglacials '' . In the terminology of glaciology , ice age implies the presence of extensive ice sheets in both northern and southern hemispheres . By this definition , we are in an interglacial period -- the Holocene -- of the ice age . The ice age began 2.6 million years ago at the start of the Pleistocene epoch , because the Greenland , Arctic , and Antarctic ice sheets still exist .

Little Ice Age <=SEP=> The Little Ice Age ( LIA ) was a period of cooling that occurred after the Medieval Warm Period . Although it was not a true ice age , the term was introduced into scientific literature by François E. Matthes in 1939 . It has been conventionally defined as a period extending from the 16th to the 19th centuries , but some experts prefer an alternative timespan from about 1300 to about 1850 . Climatologists and historians working with local records no longer expect to agree on either the start or end dates of the period , which varied according to local conditions .   The NASA Earth Observatory notes three particularly cold intervals : one beginning about 1650 , another about 1770 , and the last in 1850 , all separated by intervals of slight warming . The Intergovernmental Panel on Climate Change Third Assessment Report considered the timing and areas affected by the Little Ice Age suggested largely-independent regional climate changes rather than a globally-synchronous increased glaciation . At most , there was modest cooling of the Northern Hemisphere during the period .   Several causes have been proposed : cyclical lows in solar radiation , heightened volcanic activity , changes in the ocean circulation , variations in Earth 's orbit and axial tilt ( orbital forcing ) , inherent variability in global climate , and decreases in the human population .

Soil <=SEP=> Soil is a mixture of minerals , organic matter , gases , liquids , and countless organisms that together support life on Earth . Soil is a natural body called the pedosphere which has four important functions : it is a medium for plant growth ; it is a means of water storage , supply and purification ; it is a modifier of Earth 's atmosphere ; it is a habitat for organisms ; all of which , in turn , modify the soil .   Soil is called the Skin of the Earth and interfaces with the lithosphere , the hydrosphere , the atmosphere , and the biosphere . The term pedolith , used commonly to refer to the soil , literally translates ground stone . Soil consists of a solid phase of minerals ( the soil matrix ) and organic matter , as well as a porous phase that holds gases ( the soil atmosphere ) and water ( the soil solution ) . Accordingly , soils are often treated as a three-state system of solids , liquids , and gases .   Soil is a product of the influence of climate , relief ( elevation , orientation , and slope of terrain ) , organisms , and its parent materials ( original minerals ) interacting over time . Soil continually undergoes development by way of numerous physical , chemical and biological processes , which include weathering with associated erosion . Given its complexity and strong internal connectedness soil has been considered as an ecosystem by soil ecologists .   Most soils have a dry bulk density ( density of soil taking into account voids when dry ) between 1.1 and 1.6 g/cm3 , while the soil particle density is much higher , in the range of 2.6 to 2.7 g/cm3 . Little of the soil of planet Earth is older than the Pleistocene and none is older than the Cenozoic , although fossilized soils are preserved from as far back as the Archean .   Soil science has two basic branches of study : edaphology and pedology . Edaphology is concerned with the influence of soils on living things . Pedology is focused on the formation , description ( morphology ) , and classification of soils in their natural environment . In engineering terms , soil is referred to as regolith , or loose rock material that lies above the solid geology . Soil is commonly referred to as earth or dirt ; technically , the term dirt should be restricted to displaced soil .   As soil resources serve as a basis for food security , the international community advocates its sustainable and responsible use through different types of soil governance .

Effigy Mounds National Monument <=SEP=> Effigy Mounds National Monument preserves more than 200 prehistoric mounds built by Native Americans . Numerous effigy mounds are shaped like animals , including bears and birds . These were built mostly in the first millennium , by peoples of the Woodland Culture . As of 2017 , they have been featured on the US quarter .   The monument is located primarily in Allamakee County , with a small part in Clayton County , Iowa , in the midwestern United States . The park 's visitor center is located in Harpers Ferry , Iowa , just north of Marquette .
Query: Not everyone is convinced that the evidence is in that climate change is responsible for extreme swings between drought and deluge.

Physical impacts of climate change <=SEP=> This article is about the physical impacts of climate change . For some of these physical impacts , their effect on social and economic systems are also described .   This article refers to reports produced by the IPCC . In their usage , `` climate change '' refers to a change in the state of the climate that can be identified by changes in the mean and/or variability of its properties , and that persists for extended periods , typically decades or longer ( IPCC , 2007d :30 ) . The climate change referred to may be due to natural causes and/or the result of human activity .

Scientific consensus on climate change <=SEP=> There is currently a strong scientific consensus that the Earth is warming and that this warming is mainly caused by human activities. This consensus is supported by various studies of scientists' opinions and by position statements of scientific organizations, many of which explicitly agree with the Intergovernmental Panel on Climate Change (IPCC) synthesis reports.  Nearly all actively publishing climate scientists (97–98%) support the consensus on anthropogenic climate change, and the remaining 2% of contrarian studies either cannot be replicated or contain errors.
