How Climate Change Will Alter Our Food
https://blogs.ei.columbia.edu/2018/07/25/climate-change-food...

“Researchers found that plants’ protein content will likely decrease significantly if carbon dioxide levels reach 540 to 960 parts per million, which we are projected to reach by 2100. (We are currently at 409 ppm.) Studies show that barley, wheat, potatoes and rice have 6 to 15 percent lower concentrations of protein when grown at those levels of CO2. The protein content of corn and sorghum, however, did not decline significantly.”

Fewer nutrients

"When grown under the CO2 levels expected by 2050, reductions of protein, iron, and zinc in common produce in some parts of the world could be anywhere from 3-17 percent. And if emissions continue at the current rate, in many countries, these nutrient declines could turn dire."

Climate change is already affecting global food production—unequally

“The world's top 10 crops— barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat—supply a combined 83 percent of all calories produced on cropland. Yields have long been projected to decrease in future climate conditions. Now, new research shows climate change has already affected production of these key energy sources—and some regions and countries are faring far worse than others.”

Ozone destruction

In other words, heat-trapping gases contribute to creating the cooling conditions in the atmosphere that lead to ozone depletion. Greenhouse gases absorb heat at relatively low altitudes and warm the surface--but they have the opposite effect in higher altitudes because they prevent heat from rising.

In a cooler stratosphere, ozone loss creates a cooling effect that results in further ozone depletion.

Less atmospheric oxygen

Falling oxygen levels caused by global warming could be a greater threat to the survival of life on planet Earth than flooding, according to new research.

Higher suicide rates as temperatures go up

Our calculations suggest that projected changes in suicide rates under future climate change could be as important as other well- studied societal or policy determinants of suicide rates (see Fig. 5a).

In absolute value, the effect of climate change on the suicide rate in the United States and Mexico by 2050 is roughly two to four times the estimated effect of a 1% increase in the unemployment rate in the European Union20, half as large as the immediate effect of a celebrity suicide in Japan45, and roughly one-third as large in absolute magnitude (with opposite sign) as the estimated effect of gun restriction laws in the United States46 or the effect of national suicide prevention programmes in Organisation for Economic Co-operation and Development countries47. The large magni- tude of our results adds further impetus to better understand why temperature affects suicide and to implement policies to mitigate future temperature rise.

Unhealthy blood CO2 concentrations causing stress on the autonomic nervous system have been measured from people in common office environments where reduced thinking ability and health symptoms have been observed at levels of CO2 above 600 ppm for relatively short-term exposures. Although humans and animals are able to deal with elevated levels of CO2 in the short-term due to various compensation mechanisms in the body, the persistent effects of these mechanisms may have severe consequences in a perpetual environment of elevated CO2. These include threats to life such as kidney failure, bone atrophy and loss of brain function. Existing research also indicates that as ambient CO2 increases in the near-future, there will be an associated increase in cancers, neurological disorders and other conditions.

No. These CO2 measurement levels are at 9,000 feet, not on the surface at sea level. The CO2 concentration at the surface is much higher, and it is becoming very common for CO2 levels to exceed 1,000 ppm at the surface, going up to 4,000 ppm in closed areas, like houses.

The measured CO2 level has seasonal peaks and lows. What is important is the Mean keeps climbing. What is also important is the rise in the mean is starting to go exponential. A decade ago, the mean was increasing about 1 ppm per year. This past year, it is increasing at 3 ppm. All the projections from the 70's have been with the assumption that the CO2 level increase would be a linear ramp up, indicating when the troposphere, the breathable atmosphere, goes into Thermal Runaway, around 2070. If the ramp up is going exponential, then the conditions for Thermal Runaway move closer, possibly around 2040. The commencement of Thermal Runaway is a mass extinction event. This is the reason for all the "sooner than expected" headlines.
