In her new book, Ruth DeFries argues that we have continually created new technologies that allow our numbers to grow. But each new invention creates a new problem—which we solve with yet another innovation that creates the next problem. Will we be able to sustain this so-far successful cycle past the great leap in technology and population of the last century?
Replacing conventional building boilers with electric heat pumps in New York City buildings could substantially increase the viability of renewable energy use in the city, according to a recent study from researchers from the Earth Institute’s Sustainable Engineering Lab.
On Monday, June 2, President Obama will announce proposed federal rules aimed at curbing carbon emissions from existing U.S. power plants–possibly a landmark in U.S. climate policy. It is uncertain how far the rule will go, and the announcement is being closely watched around the world.
Carbon capture, storage and reuse has the potential to help us reduce CO2 emissions and combat global warming. The Lenfest Center for Sustainable Energy is bringing together experts from an array of fields to assess the state of the technology April 14-16.
Scientists from Columbia University’s Earth Institute will present important research results and special events at the Dec. 9-13 San Francisco meeting of the American Geophysical Union, the world’s largest gathering of earth and space scientists. Here is a guide in rough chronological order.
Trees play a vital role in cleaning air and absorbing carbon dioxide.
Last October, Superstorm Sandy provoked widespread frustration and fear after it left more than 7.5 million people in the New York Metro area without power. In the hardest hit areas, outages lasted two weeks or more. These failures led many observers to wonder if America’s aging electrical grid was up to dealing with emerging climate and other challenges.
Where are materials for all tech gadgets coming from? Where is e-waste going? What policies are associated with these issues and are they working? Find out at a panel discussion and screening of Terra Blight.
Pushker Kharecha and James E. Hansen write about their recent paper on the long-term health effects of nuclear power versus fossil fuels, and argue that nuclear power needs to be part of the solution to climate change.
So far, tensiometers have been tested in four central districts of Punjab, initially with more than 500 farmers the first year, and then peaking with an additional 4,500 farmers in 2011 before testing was scaled back. Data showed, on average, a 30 percent reduction in the water used in the test plots when compared with the standard practices employed in the control plots.
