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 ...

Climate is the average state of the atmosphere and the underlying land or water, on time scales of seasons and longer. Climate is typically described by the statistics of a set of atmospheric and ...

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 ...

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 ...

How do you measure climate change? One way is by recording temperatures in different places over a long period of time. While this works well, natural variation can make it harder to see longer-term ...

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 ...

Global heating over this millennium could exceed previous estimates due to carbon cycle feedback loops. This is the conclusion of a new study by the Potsdam Institute for Climate Impact Research (PIK) ...

A new study reveals that biochar, a carbon-rich material increasingly used in agriculture, can significantly influence how soils respond to warming when releasing nitrous oxide, a potent greenhouse ...

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 ...

Adaptation to climate has long been disparaged by climate advocates. Adaptation has been framed as an avoidable cost of the failure to mitigate, fundamentally limited in its effectiveness in reducing ...
