Writing in a paper published Wednesday in Nature, scientists describe what they call the velocity of climate change, or more specifically, the speed of Earth's shifting climatic zones. As global temperature rises over the next century, the scientists argue, Earth's habitable climatic zones will start moving too, generally away from the Equator and toward the poles. That means many species of plants and animals will also have to move in order to survive. Whether or not they do will depend on several factors, but two of the most important are how fast a species can adjust its habitat...
Until now, ecologists have mostly focused on these factors as they affect individual species, but the new paper takes a more global view. By combining temperature projections on a very fine scale with global topographic maps, researchers have predicted change not for specific species, but for the climatic zones they need to keep up with...
Indeed, because global temperature is rising now, ecosystems are already on the move. "Once you explain it to people, it makes intuitive sense," says co-author David Ackerly, a University of California, Berkeley, biologist. "We know what it's like to drive north to escape the heat. It's concrete, rather than the abstractness of rising average temperatures." (See the top 10 green ideas...

...There's a complete turnaround," says Gianander Dua, an importer based in New Delhi. He represents not just French and Italian wines but also those from Argentina and Austria, which are much smaller wine-exporting countries. They all see the Indian consumer as a safe harbor in a global recession, Dua says. "The buying capacity in India is there." (Read "Recession? Not in New Delhi's Luxury Stores...
