We've been watching temperatures climb, extreme weather events intensify, and ice sheets shrink. Every weather forecast and climate projection relies on incredibly complex computer simulations that ...

Have you ever stopped to wonder how forecasters can predict the weather days in advance, or how scientists figure out how the ...

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 ...

Climate models provide reliable projections of many aspects of a warming planet over the next century and beyond due to human-caused climate change. Climate models are sets of mathematical equations ...

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 ...

After a record fall, when nearly the entire United States experienced drought—unprecedented in US Drought Monitor history—water managers and planners nationwide are nervously hoping for a wet winter, ...

Climate models have been the basis for concern about climate change for more than 35 years. The US government, the United Nations, and organizations across the world have used model projections to ...

Satellite image provided by the National Oceanic and Atmospheric Administration shows Hurricane Melissa churning northwest through the Caribbean Sea. The Category 5 hurricane is a recent example of ...

Scientists warn that unpredictable climate swings could bring mosquito-borne disease outbreaks years earlier than expected, urging governments to act now on surveillance and preparedness. Study: ...

The Heritage Foundation recently published a paper from the leading scientists at the Center for Environmental Research and Earth Sciences (CERES) that argues the debate over the causes and ...
