Thermodynamical and dynamical aspects of the climate system response to anthropogenic forcing are often considered in two distinct frameworks: the former in the context of the forcing–feedback ...

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 ...

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 ...

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 ...

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) ...

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 ...

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 ...

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 ...

The DSCIM model, which was adopted by the Biden Administration, attempts to quantify the social cost of carbon (SCC). Adjusting DSCIM to more reasonable assumptions results in a substantial reduction ...

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 ...
