Exceptionally long heat waves and other hot events could become commonplace in the United States in the next 30 years, according to a new study by Stanford University climate scientists. "Using a large suite of climate model experiments, we see a clear emergence of much more intense, hot conditions in the U.S. within the next three decades," said Noah Diffenbaugh, an assistant professor of environmental Earth system science at Stanford and the lead author of the study. Writing in the journal...

Climate scientists have emerged from an inquiry with their reputations still intact. The Independent Climate Change Email Review was set up by the University of East Anglia (UEA) after over 1,000 emails were hacked into through its servers. Climate "skeptics" claimed that the emails proved that UEA scientists manipulated key climate data involving climate change. However, these accusations are largely dismissed by the report. The review did not discover anything in the emails to undermine...

The small number of scientists who are unconvinced that human beings have contributed significantly to climate change have far less expertise and prominence in climate research compared with scientists who are convinced, according to a study led by Stanford researchers. In a quantitative assessment "“ the first of its kind to address this issue "“ the team analyzed the number of research papers published by more than 900 climate researchers and the number of times their work was...

Anaerobic manure treatment lagoons may release more methane than current rules allow The approach the U.S. Environmental Protection Agency (EPA) uses to estimate greenhouse gas emissions from agricultural anaerobic lagoons that treat manure contains errors and may underestimate methane emissions by up to 65%, according to scientists from the University of Missouri. Anaerobic lagoons treat manure on some animal feeding operations prior to application to crops as a fertilizer. Methane, one...

The Earth is heading for a 5.4-degree Fahrenheit warming trend by the year 2100 despite promises to curb carbon emissions, according to a study released during UN talks on Thursday. Bill Hare of Germany's Potsdam Institute for Climate Impact Research (PIK), said there is a "virtual certainty" that global warming will exceed 2.7 F by 2100. It could very likely exceed 3.6 F and there's a "more than 50-percent chance of exceeding 5.4 F by 2100." Nearly 120 countries have signed up to take...

Vegetation around the world is on the move, and climate change is the culprit, according to a new analysis of global vegetation shifts led by a University of California, Berkeley, ecologist in collaboration with researchers from the U.S. Department of Agriculture Forest Service. In a paper published today in the journal Global Ecology and Biogeography, researchers present evidence that over the past century, vegetation has been gradually moving toward the poles and up mountain slopes, where...

The head of the United Nation's climate change panel defended its case against an academic council charged with reviewing its research methods after a string of challenges to its findings. Rajendra Pachauri, a chairman of the Intergovernmental Panel on Climate Change (IPCC), said there was an error made when warning that the Himalayan glaciers could melt by 2035.  However, he said there was some value to the findings. "Alright, there was this error, but there is a whole lot of valid...

NSF-supported climate scientist Mark Flanner and colleagues find differences in the rates for spring warming and snow cover decline in Eurasia and North America, and are studying whether aerosols are a key factor Over the past 30 years, springtime snow melt and warming appear to be proceeding at a faster rate in Eurasia than in North America. Climate scientist Mark Flanner, an assistant professor at the University of Michigan and a recent Advanced Study Program graduate at the National...

They may be more tolerant of droughts than previously thought A new NASA-funded study has concluded that Amazon rain forests were remarkably unaffected in the face of once-in-a-century drought in 2005, neither dying nor thriving, contrary to a previously published report and claims by the Intergovernmental Panel on Climate Change. "We found no big differences in the greenness level of these forests between drought and non-drought years, which suggests that these forests may be more tolerant...

The struggling Intergovernmental Panel on Climate Change has given an outside science group complete control to review its rules, procedures and reports on global warming. The InterAcademy Council, a Netherlands-based organization of the science academies of 15 nations, will undertake the task of reviewing the IPCC's reports by independently choosing reviewers, a scientist close to the situation, who asked not to be named, told the Associated Press (AP). The IPCC has had several troubling...
