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 ...

Current global climate models (GCMs) support with high confidence the view that rising greenhouse gases and other ...

Global climate models capture many of the processes that shape Earth's weather and climate. Based on physics, chemistry, ...

Climate models may be underestimating—by anything from half to two degrees—how much hotter India’s non-metropolitan cities ...

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 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 ...

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 ...

The report warns many economic models are failing to capture extreme weather events and rising uncertainty likely to dominate impacts in a hotter world.
