Some of the recent research on climate change published in scientific journals includes:
May, Environmental Research Letters
Some 97 percent of scientists who presented their conclusions in research published in peer-reviewed journals agree that humans lie behind an observed increase in average, global temperatures. A team of researchers reviewed 2,000 scientific papers involving the work of 10,000 climate scientists published in the past 21 years and found that 97 percent not only agree that average temperatures have increased, but blamed humans and the release of heat-trapping gases into the atmosphere. However, only about half of the general public thinks that scientists agree on this point.
Heat rise estimated:
May, Nature Climate Change
The planet will warm up by between 4.3 and 7 degrees (F) by 2100, according to a study that combined observations of carbon dioxide and global temperature variations with the output of numerous climate computer models by a team from Victoria University in Australia. Previous studies have predicted substantial impacts on crops, weather and civilization with a 4 degree warming. A 7 degree warming would have drastic effects.
Missing heat found:
November, Quarterly Journal of the Royal Meteorological Society
The polar regions are heating up about eight times faster than the rest of the planet, which along with a lack of historical data on polar temperatures plus a lack of good data on temperature patterns in Africa largely explains a reported decrease in the pace of global temperature rise in the past decade, according to the a study by researchers from the University of New York.
Swamps store methane:
March, Nature, University of Exeter
Swamps, bogs and other water saturated environments have a peculiar chemistry that locks up huge amounts of methane by denying bacteria the oxygen they need to metabolize and release the methane. Turns out, methane is 25 times more efficient at trapping heat than carbon dioxide, so it’s a much more potent greenhouse gas. A rise in average temperatures and a projected increase in drought and weather instability could uncover those wetlands, resulting in a rapid change in chemistry that could release large quantities of methane. The frozen tundras of Siberia and elsewhere could also release prodigious amounts of methane as the planet warms – leading to a much more rapid increase in global temperatures than previously predicted.
Carbon dioxide and soil:
Indiana University, Ecology Letters
Increased carbon dioxide in the atmosphere can actually increase the amount of carbon dioxide released through decomposition in the soil. The researchers monitored carbon cycles in an experimental forest for 14 years and found that as carbon dioxide levels in the atmosphere rose the fungi and bacteria in the soil and on roots increased their activity and cycling of nitrogen which resulted in a sharp increase in the release into the atmosphere of even more carbon from the soil — and unexpected feedback effect not considered in most models.
