A new open-access tool that dramatically speeds up the evaluation of climate models has been launched by an international team of scientists. The Rapid Evaluation Framework (REF) allows researchers to ...

Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are called isotopes. As water evaporates or moves through the atmosphere, the ...

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 ...

Scientists have developed a powerful new way to trace the journey of water across the planet by reading tiny atomic clues hidden inside it. Slightly heavier versions of hydrogen and oxygen, called ...

Agency cuts, layoffs and policy shifts are throwing America’s role into question. The world’s largest climate modeling initiative is quietly ramping up its next project, but U.S. participation is a ...

Models, by definition, are approximations: useful, informative, and inevitably incomplete, because they are the only way to simplify a world too complex to grasp all at once. A new study on nitrous ...

Rapid attribution reports generate good headlines and play into the narrative that anthropogenic climate change causes everything bad, ...

Lee Zeldin opened a meeting of the Heartland Institute, which has compared environmental advocates to the Unabomber.

Most Americans now accept the basic physics of climate change—that manmade greenhouse-gas emissions are raising global temperatures. Yet the public discussion of climate change is still remarkably ...
