Lester Brown, the global environmental leader, turned 81 this year and is closing The Earth Policy Institute, the environmental research organization he founded in 2001. His new book “The Great Transition” asserts that the world is shifting from fossil fuels to solar and wind energy.

A group of 17 renowned scientists from around the world are appealing for dramatic action to forestall the worst effects of climate change, issuing an “Earth Statement” that calls for a world powered with zero carbon emissions by mid-century.
The issue for Earth Day, 2015, is how we marshal the forces of technology toward the goal of creating a sustainable, high-throughput economy. Some of these new technologies will damage our environment. Some, like solar power, can help protect the environment.

One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and…

Lamont-Doherty Earth Observatory has been a leader in the study of our planet since its founding 65 years ago. Today, Observatory scientists continue the institution’s long tradition of addressing important questions in the Earth and planetary sciences.

Columbia University is teaming up with Cornell University to co-host the second International Global Food Security Conference to bring together 500-plus scientists to investigate the behavioral, biophysical, economic, institutional, political, social and technological drivers of current and future global food security.

Convincing farmers that it’s worth it to reduce their water consumption will rest on our ability to help develop local groups to manage aquifers at the community-level.

Iceland is pioneering a new technology to deal with climate change. Its Hellisheidi geothermal power plant, the world’s largest, hosts arguably the world’s most advanced program to capture and lock away globe-warming carbon dioxide.

Iceland has a complicated relationship with climate change. As in much of the far north, global warming is already exerting many effects here–arguably both good and bad. Yet the country contributes relatively little to the warming, since most of its energy comes from geothermal and hydro plants, which produce little carbon dioxide. Now, it is…
