How hot will it be this century? The latest climate models suggest it could be worse than we thought
Climatologists use mathematical models to project Earth’s future in a warming world, but a group of latest models included surprisingly high values for a measure called “climate sensitivity.” Climate sensitivity refers to the relationship between changes in carbon dioxide in the atmosphere and warming. High values are a bad surprise. If they’re right, that means […]

Even 50 years ago, climate models were far more accurate than deniers claim
It’s a common refrain from those who question the findings of climate science: the computer models scientists use to project future global warming are inaccurate and shouldn’t be trusted to help policymakers decide whether to they must take potentially costly measures to limit greenhouse gas emissions. A new study effectively quells this argument by examining […]
Climate models have understood global warming well
There’s a favorite argument among those who doubt mainstream climate science: climate models overestimate the rate at which the Earth is warming. This claim resurfaces time and time again and is often based on single instances of uncertainty or hand-picked data. Various studies have looked closely at individual climate models in recent years and have […]
Individual climate models may not provide the complete picture
UNIVERSITY PARK, Pennsylvania — Equilibrium climate sensitivity — the sensitivity of Earth’s climate to changes in atmospheric carbon dioxide — may be underestimated in individual climate models, according to a team of climatologists. “Probabilistic estimates of climate system properties often rely on comparing the model simulation with observed temperature records and an estimate of internal […]
