Parts of the central United States may become more prone to summertime drying than earlier thought, based on new simulations of climate change that involve both global and regional climate models.

A grand solar minimum would slow global warming but not stop it.

A rare confluence of three atmospheric patterns drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably.

Scientists are zeroing in on microbes that eat carbon in the soil and release it back to the atmosphere, thereby influencing global climate.

Levels of carbon dioxide in the atmosphere are fluctuating more than they used to from one season to another, according to observations from the HIPPO field project. This may be a sign of significant changes in northern ecosystems.
