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 ...

Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are ...

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 ...

Tiny marine plankton that build calcium carbonate shells play an outsized role in regulating Earth’s climate, quietly pulling carbon from the atmosphere and helping lock it away in the deep ocean. New ...

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 ...

Science is nuanced. This basic truth certainly holds for the field of atmospheric science, where the complexities of the airy environment are investigated. The climate science subdiscipline explores ...

Click the downloadable graphic: What is attribution science? Humans have increased Earth’s temperature, mainly by burning fossil fuels like coal, oil, and methane gas. The resulting heat-trapping ...

The report warns many economic models are failing to capture extreme weather events and rising uncertainty likely to dominate ...
