Scientists can now study climate change in far more detail with powerful new computer software released by the National Center for Atmospheric Research (NCAR).The Community Earth System Model (CESM) will be one of the primary climate models used for the next assessment by the Intergovernmental Panel on Climate Change (IPCC). The CESM is the latest in a series of NCAR-based global models developed over the last 30 years. The models are jointly supported by the Department of Energy (DOE) and...

Global warming is at least partially to blame for a recent bout of hot and dry weather that has triggered wildfires in Russia, according to experts interviewed by AFP and BBC News this week. "The Russian heatwave is related to a persistent pattern of circulation drawing air from the south and east (the very warm steppes)," Dr. Jeff Knight, a climate variability scientist at the UK Met Office, told BBC Science Reporter Katia Moskvitch Tuesday. "Circulation anomalies tend to create warm and...

California, Pacific Northwest and Colorado achieve positive net impacts; other states languish A climate-change study at Sandia National Laboratories that models the near-term effects of declining rainfall in each of the 48 U.S. continental states makes clear the economic toll that could occur unless an appropriate amount of initial investment "” a kind of upfront insurance payment "” is made to forestall much larger economic problems down the road. Why tie climate change to...

Greatest Risks Seen in 14 States: AZ, AR, CA, CO, FL, ID, KS, MS, MT, NE, NV, NM, OK and TX; How Big a Threat to Food Supply? At-Risk Counties Are Home to Over $100 Billion in Crops. WASHINGTON, July 20 /PRNewswire-USNewswire/ -- Over 1,100 U.S. counties-- more than one-third of all counties in the lower 48 states -- now face higher risks of water shortages by mid-century as the result of global warming and more than 400 of these counties will be at extremely high risk for water...

A key tool is the JRC's methodology to quantify changes to the amount of carbon in soils and biomass when land use changes as a result of biofuels production. This is an important factor in the sustainability assessment. The methodology follows the Intergovernmental Panel on Climate Change (IPCC) guidelines for national greenhouse gas inventories and is supported by comprehensive global data collected by the JRC. The methodology was the basis for the Commission decision on the guidelines for...

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...
