The French Academy of Science said in a report published Thursday that global warming exists and is unquestionably due to human activity. "Several independent indicators show an increase in global warming from 1975 to 2003. This increase is mainly due to the increase in the concentration of carbon dioxide," the academy said in conclusion to the report. "The increase in carbon dioxide, and to a lesser degree other greenhouse gases, is unquestionably due to human activity," said the report,...

NSF invites media to participate in a webcast briefing on Thursday, Oct. 28 at 1:00 p.m., EDT Clouds are "the largest source of uncertainty" in projections of climate change, according to the Intergovernmental Panel on Climate Change (IPCC). This uncertainty arises because different types of clouds exert different forces on climate: Some clouds help cool the Earth and some clouds help warm it. So far, no one knows which effect will win out as the climate continues to change. This uncertainty...

A new review released Monday says that the U.N.'s climate panel needs to "fundamentally reform" its structure in order to try and prevent the embarrassing errors found in a 2007 study on global warming. A U.N.-requested investigation of the Intergovernmental Panel on Climate Change (IPCC) discovered that the Nobel Prize-winning body was successful, despite the "Climategate" scandal that took place before the Copenhagen meeting last fall. The five-month review plans to replace the IPCC's...

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...
