We were thrilled to welcome Bill Gates recently to the Earth Institute for a wide-ranging informational meeting led by director Jeff Sachs. The half-day visit was a lively, frank and open exchange of ideas between Mr. Gates and Earth Institute faculty members debating the challenges and immense opportunities for human development in the areas of…
The magnitude 6.0 earthquake that struck Malawi on Saturday night, December 19, spurred us into action. We had been closely following the earthquakes there, but this one confirmed the unusual nature of the seismic sequence. It also happened to be the most destructive. Leonard Kalindekafe, director of Malawi’s Geological Survey, asked us to come and…
In Reversal, Land Is Cleared for Global Trade and Big Cities, Says Study
As a child, I believed that I could hear the ocean in a seashell. Now when I think about the sounds of the sea, I imagine the roar of waves crashing on the beach. But from the vantage point of a ship with noisy engines, the water seems silent. In 1490, Leonardo da Vinci observed,…
“A scientific network set up recently by India’s environment ministry will contribute formally to the Intergovernmental Panel on Climate Change (IPCC), the country’s prime minister has announced.
Today we arrived at McMurdo, an American research station that hosts Antarctica’s largest community—about 1,000 people during austral summer. To get here, a US Air Force cargo plane picked us up in Christchurch, New Zealand, and landed us on the ice nearby. Today is a balmy summer day of 30°F, not much colder than the…
Earthquakes can be devastating, as Haiti has shown. They can trigger tsunamis, like the one in Indonesia in 2004, and create enough ground shaking to topple buildings. Aftershocks can prevent people from returning to their homes for weeks, even months. The immediate response to a natural disaster is to search for those lost, treat the…
Africa is ripping apart along a 4,000 kilometer seam called the East Africa Rift, which stretches from the Red Sea to Mozambique. This huge continental tear started in the north about 25 million years ago and has been gradually unzipping to the south, with rifting in Malawi starting about 10 million years ago. Breaking up…
In December, nearly a dozen earthquakes of magnitude 5 or greater rattled the southeast African nation of Malawi, killing four, injuring hundreds, and making thousands homeless. The region had been calm for decades, so the earthquakes caught everyone by surprise. But aftershocks continue, and more quakes can be expected. Seismologists from Columbia University’s Lamont-Doherty Earth…
