Prof. Göran Ekström	Professor	Göran Ekström's main research interest is global earthquake seismology. This includes the detailed study of individual earthquake ruptures, and the relationship between seismicity and the large scale tectonic deformation of the crust and mantle over geologic time. Prof. Ekström's teaching interests include Environmental Geology, in particular the science and policy aspects of the assessment and mitigation of Geologic Hazards.

Look at Glaciers Past Suggests Greenland Melting Could Rapidly Heighten Sea Level

North American Ice Sheet Dwindled Fast in Conditions Like Today's

In the face of warming climate, researchers have yet to agree on how much and how quickly melting of the Greenland ice sheet may contribute to sea level rise.

New Dating Technique Points to Differences Over 7,000 Years

The vast majority of the world’s glaciers are retreating as the planet gets warmer. But a few, including ones south of the equator, in South America and New Zealand, are inching forward. A new study in the journal Science puts this enigma in perspective.
Glacial Earthquakes Point to Rising Temperatures in Greenland
March 23, 2006
Seismologists at Columbia University and Harvard University have found a new indicator that the Earth is warming: "glacial earthquakes" caused when the rivers of ice lurch unexpectedly and produce temblors as strong as magnitude 5.1 on the moment-magnitude scale, which is similar to the Richter scale. Glacial earthquakes in Greenland, the researchers found, are most common in July and August, and have more than doubled in number since 2002.

A new study adds evidence that climate swings in Europe and North America during the last ice age were closely linked to changes in the tropics. The study, published this week in the journal Science, suggests that a prolonged cold spell...
