Un nuevo Atlas Sudamericano de Sequía revela que las sequías severas expandidas y los períodos inusualmente húmedos sin precedentes han ido aumentando desde mediados del siglo XX.
A new South American Drought Atlas reveals that unprecedented widespread, intense droughts and unusually wet periods have been on the rise since the mid-20th century.
Lawsuits based on corporate misrepresentations to investors are gaining attention from those who want to see companies held more accountable for environmental damage–including risks associated with climate change.
On a ledge just inside the lip of Chile’s Quizapu volcanic crater, Philipp Ruprecht was furiously digging a trench. Here at an elevation of 10,000 feet, a 1,000-foot plunge loomed just yards away, and wind was whipping dust off his shovel. But the volcanologist was excited. Ruprecht had just found this spot, topped with undisturbed wedding-cake layers of fine, black material that the crater had vomited from the deep earth some 84 years ago. Samples from the currently inactive site might shed light on its exceedingly violent behavior.
High in the southern Andes, Chile’s Quizapu crater is one of South America’s most fearsome geologic features. In 1846, it was the source of one the continent’s largest historically recorded lava flows. In 1932, it produced one of the largest recorded volcanic blasts. The volcano is currently inactive, but could revive at any time. What is next?
On every continent and ocean, Earth Institute field researchers study the dynamics of climate, geology, ecology, human history and more. Here is a list of expeditions going on this year, and beyond.
In this Q&A, Arthur M. Greene discusses improving climate and agricultural modeling in South America using a new stochastic simulation of future climate.
Earth Institute scientists explore how the physical world works on every continent — over and under the arctic ice, in the grasslands of Mongolia, on volcanoes in Patagonia, over subduction zones in Papua New Guinea, and on the streets of New York City.
After more than six weeks trawling the Peruvian Andes in search of palaeoclimate clues, our field team is visiting the last site, a potential calibration sites near Coropuna. The objective of that ongoing work is to refine the cosmogenic surface-exposure method for the tropics, thereby improving the precision of new and existing datasets.
Our field team has set camp at 5045 m on the dusty slopes of Ampato, an extinct, ice-clad volcano in the Western Cordillera. This is the very mountain from which Juanita, the famous Incan ‘ice maiden’, was plucked back in 1995. The tents are clustered in the lee of a large glacial erratic and, now the clouds have cleared, the view is second to none, taking in the dry plains far below and myriad volcanic peaks in every direction.
