Something unexpected happened in the climate science community over the past two years. While global temperatures soared to unprecedented levels in 2023 and 2024, researchers found themselves unable ...

High-sensitivity climate models should not be excluded when predicting future regional climate impacts because the level of warming measured globally is not always the only good indicator of regional ...

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 ...

Many people feel anxious about climate change and other trends in the world around us. However, there are constructive ways ...

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

Atmospheric aerosols from human activity influence climate. Uncertainties in the understanding of their effects limit our knowledge about climate change. Aa Aa Aa What is the source and composition of ...

Over the past four years, the Biden Administration relied extensively on integrated assessment models (IAMs) to quantify the economic effects of carbon-dioxide emissions via a construct known as the ...

As we celebrate Earth Month, we are kicking off a series of retrospectives on National Academies’ reports and activities related to climate science. The National Academies took on the complex ...

Climate forcings drive changes in the Earth system, causing its components to respond and interact in many ways, often on different timescales. Tectonic processes, for example, generated by mantle ...
