Climate modeling is one of the most demanding intellectual exercises humans have ever attempted. Scientists are essentially ...

Current global climate models (GCMs) support with high confidence the view that rising greenhouse gases and other anthropogenic forcings account for nearly all observed global surface warming—slightly ...

Internal climate variability refers to the natural fluctuations arising from the chaotic interactions within the atmosphere, ocean, cryosphere and land surface. Ensemble climate models exploit this ...

Gerald A. Meehl (Chair) is a Senior Scientist at the National Center for Atmospheric Research. He received his PhD in climate dynamics from the University of Colorado. His research interests include ...

The warnings are no longer theoretical. A March 11 report, covered by the Hartford Courant, suggests that scientists at NOAA, ...

Climate is constantly changing and will continue to do so; we cannot assume a stable climate system even in the absence of anthropogenic influences. Such variability manifests itself over a continuum ...

The intensifying and expansive heat wave affecting around 150 million people in the United States from Wisconsin to Washington, DC, bears the hallmarks of human-caused global warming. Hundreds of ...

A new Murdoch University study has found that cold-blooded animals (ectotherms) are unable to adjust physiologically to daily temperature fluctuations, a limitation that could leave them increasingly ...

A new report from the American Academy of Microbiology examines how attribution science is measuring the infectious disease burden caused by climate change.
