Two teams of Yale researchers independently reached identical conclusions about the nature of Pacific currents in the Pliocene era, a time with carbon dioxide levels and sea surface temperatures ...

A large dead zone existed in the North Atlantic Ocean the last time global temperatures were as high as they could be 100 years from now, according to a new study led by an N.C. State University ...

A recent study by an international research group led by Prof. AO Hong from the Institute of Earth Environment of the Chinese Academy of Sciences has revealed Asian climate variability and dynamics ...

Projections based on climate models for the mid-Pliocene Warm Period (about 3 million years ago) suggest that countries in the tropical and subtropical southern hemisphere, including Brazil, may face ...

The amount of heat-trapping carbon dioxide in the atmosphere has shot past a key milestone — more than 50% higher than pre-industrial times — and is at levels not seen since millions of years ago when ...

From the ancient sludge of lakebeds in Asia’s Tibetan Plateau, scientists can decipher a vision of Earth’s future. That future, it turns out, will look very similar to the mid-Pliocene warm period – ...
