Researchers have long been puzzled by the observed cooling of the eastern tropical Pacific and the Southern Ocean ...

We've been watching temperatures climb, extreme weather events intensify, and ice sheets shrink. Every weather forecast and climate projection relies on incredibly complex computer simulations that ...

Models, by definition, are approximations: useful, informative, and inevitably incomplete, because they are the only way to simplify a world too complex to grasp all at once. A new study on nitrous ...

The cover photo, taken at the Strait of Malacca in Malaysia, captures the Tyndall effect as sunlight filters through the clouds over the tropical Pacific. The interplay of light and shadow ...

Current global climate models (GCMs) support with high confidence the view that rising greenhouse gases and other ...

After a record fall, when nearly the entire United States experienced drought—unprecedented in US Drought Monitor history—water managers and planners nationwide are nervously hoping for a wet winter, ...

Climate models provide reliable projections of many aspects of a warming planet over the next century and beyond due to human-caused climate change. Climate models are sets of mathematical equations ...

To achieve the 2 °C target, the total amount of carbon that can still be emitted by human activities is limited. This total allowable carbon emission—called the remaining carbon budget—is illustrated ...

If temperatures continue to rise, by the end of the century, Delaware’s climate could resemble that currently experienced in ...

People often think of a heatwave as a temporary event, a brutal week of sun that eventually breaks with a cool breeze. But as the climate changes globally, in parts of Africa, that level of heat is ...
