A CONVERSATION WITH PHILIP RASCH, PhD, CHIEF SCIENTIST FOR CLIMATE AT THE PACIFIC NORTHWEST NATIONAL LABORATORY

by Erica Rex Dr. Philip Rasch focuses on understanding the connections between clouds, chemistry, and the climate. He co-chairs the Atmospheric Model Working Group of the Community Climate System Model project. Dr. Rasch and his team create mathematical models of what the Earth’s climate might look like in the future by varying their assumptions about conditions such as carbon dioxide concentration and temperature. Each of the scenarios created using these models provides insights into what... [Read more]

GEOENGINEERING THE CLIMATE II: THE DOWN SIDE

by Erica Rex Despite its great potential for remedying the climate crisis, once put into practice, geoengineering may turn out the way of many panaceas. A great idea in theory, and an expensive disaster in practice. In the 21 August 2009 issue of the journal Science, scientists Gabriele C. Hegerl of the Grant Institute in Edinburgh, Scotland, and Susan Solomon of the National Oceanographic and Atmospheric Administration in Boulder, Colorado, point out some of the downsides. They write: “ [By]... [Read more]

ALBEDO YACHTS AND ALGAE BLOOMS: CURES FOR THE EARTH’S MAN-MADE FEVER?

by Erica Rex Question: since we’re the ones responsible for breaking the climate, shouldn’t we be the ones to fix it? This is exactly the question posed by climate scientists at the The Royal Society, a hallowed UK institution whose past members include such luminaries as Sir Isaac Newton and Charles Darwin. Last week, the society issued a study called “Geoengineering the Climate: science, governance and uncertainty.” The study points out that it is likely the Earth will... [Read more]

THE HOT ZONE

Welcome to The Hot Zone, a climate change and global warming blog sponsored by the Goddard Institute for Space Studies and Astrobiology Magazine. Last year, James Hansen, director of the National Aeronautics and Space Administration Goddard Institute for Space Studies and Adjunct Professor of Earth and Environmental Sciences at Columbia University’s Earth Institute, wrote these words: “Our home planet is dangerously near a tipping point at which human-made greenhouse gases reach a level... [Read more]
