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 ...

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

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 scenarios must include fairness and equity to create realistic emissions pathways and support global cooperation.

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

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

More than 295 million people globally experienced hunger and starvation in 2025 because of conflict, displacement, climate change and economic disasters. The bad news is that things are going to get a ...

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

Researchers say governments and financial institutions underestimating threat because they rely on models that assume climate ...

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 ...
