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...

As part of its most comprehensive study of climate change to date, the National Research Council today issued three reports emphasizing why the U.S. should act now to reduce greenhouse gas emissions and develop a national strategy to adapt to the inevitable impacts of climate change. The reports by the Research Council, the operating arm of the National Academy of Sciences and National Academy of Engineering, are part of a congressionally requested suite of five studies known as AMERICA'S...

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...

Fulfilling Copenhagen Accord will require variety of efforts ranging from 'Herculean' to the readily actionable, scientists say Major greenhouse gas-emitting countries agreed in December climate talks held in Copenhagen that substantial action is required to limit the increase of global average temperature to less than 2 degrees C (3.6 degrees F). In a paper appearing May 3 in the Proceedings of the National Academy of Sciences (PNAS), Veerabhadran Ramanathan and Yangyang Xu, climate...

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...

Iceland's volcanic eruption, which grounded air traffic for days, may provide rare clues as to how flights encourage climate change, adding to evidence from a ban on US flights after the World Trade Center attacks on September 11, 2001, according to a recent Reuters report. How jet fuel being burned at high altitudes affects climate is poorly understood, largely because scientists cannot often compare plane-free skies with the everyday air traffic that clutters many regions. Not since 2001...

New Climate Central projection map shows local and national retreat of freezing temperatures in March On March 31, Climate Central published an interactive animated map showing what we might expect in Marches to come as the climate warms. Developed by Climate Central scientists, the map uses special high-resolution projections covering the Lower 48 states to show where average March temperatures are expected to be above or below freezing each decade this century. The map also compares...

New interagency program to generate high-resolution tools for addressing climate change The National Science Foundation (NSF) and the U.S. Departments of Energy and Agriculture held a webcast announcing the launch of a joint research program to produce high-resolution models for predicting climate change and its resulting impacts. Called Decadal and Regional Climate Prediction Using Earth System Models (EaSM), the program is designed to generate models that--significantly more powerful than...

Australia's average temperature is on the rise, providing compelling evidence of the validity of climate change, claims the country's top group of scientists in a report released on Monday. The Commonwealth Scientific and Industrial Research Organization (CSIRO), in a joint "State of the Climate" report with the Bureau of Meteorology, presented findings that the country's mean temperature has increased by 0.7 degrees Celsius in the past 50 years, though some areas have experienced as much as...
