The effects of melting glaciers on tropical communities

A Penn State professor is researching the trickle-down effects that melting tropical glaciers have on food security and biodiversity, and what regional communities, like Cusco and Huaraz in Peru, can do about it.

Understanding the ebb and flow of Peru's glacial past

Many thousands of years ago, as the world slowly began to thaw at the end of the last ice age, the landscapes of southern Peru were quite different than the ones University of Maine's Gordon Bromley finds himself wandering ...

Melting glaciers pose threat beyond water scarcity: floods

The tropical glaciers of South America are dying from soot and rising temperatures, threatening water supplies to communities that have depended on them for centuries. But experts say that the slow process measured in inches ...

Tropical sea temperatures influence melting in Antarctica

Accelerated melting of two fast-moving outlet glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely the result, in part, of an increase in sea-surface temperatures in the tropical Pacific Ocean, according ...

Causes of melting tropical glaciers identified

The causes of melting of tropical glaciers over the past 10 000 years have at last been unveiled by a team of French researchers from CNRS, CEA, IRD and Universite Joseph Fourrier, together with a US researcher from the University ...

Volcanoes cool the tropics, say researchers

Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics—but suggest that such effects may have been masked in the 20th century by rising global temperatures. ...
