Climate models that give a low warming from increases in greenhouse gases do not match satellite measurements. Future warming will likely be worse than thought unless society acts, according to a new ...

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 ...

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 ...

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 ...

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 ...

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) ...

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 ...
