Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

Scientists have presented a model that elucidates the chain of physical processes driving interannual Hadley cell expansion in the Northern Hemisphere. The Hadley circulation is a key atmospheric ...

Right now, the world’s best weather forecast model is a General Circulation Model, or GCM, put together by the European Center for Medium-Range Weather Forecasts. A GCM is in part based on code that ...

Special features of the Arctic climate, such as the strong reflection of the sun's rays off the light snow or the low position of the sun, amplify global warming in the Arctic. However, researchers ...

Explosive volcanic eruptions can influence the climate for years – for example, through ash and sulphur particles injected into the atmosphere that reduce solar radiation. Conversely, geological ...

Hardly a day passes without a popular article describing the latest scientific study of rapid changes in Antarctic glaciers and ice shelves, or the latest research highlighting a possible slowdown of ...

Over the past 60 years, scientists have largely succeeded in building a computer model of Earth to see what the future holds. One of the most ambitious projects humankind has ever undertaken has now ...
