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...
Harvard researchers have discovered a "super-Earth" orbiting a red dwarf star 40 light-years from Earth with telescopes no larger than those used by amateur stargazers...
...team believes that the planet—named GJ1214b after the red dwarf star it orbits and 6.5 times the Earth's size—is primarily composed of water and ice but, at roughly 400 degrees Fahrenheit, is too hot to sustain life...
Harvard astronomy professor David Charbonneau and his colleagues discovered the super-Earth using the MEarth (pronounced "mirth") Project, an array of eight robotic telescopes that have monitored 2,000 red dwarf stars since...
...Naturally, the plan is not without its critics. The environmental group Friends of the Earth says it will do little to reduce traffic, since driving, for the most part, will still be cheaper than using public transport, even on long trips. And some transport experts argue that road improvement projects - such as building better links connecting the main highways that crisscross the country - would be more effective at reducing congestion. "It's not simply about using cars and roads less, but about using them better," says Christophe Nicodème, head of the European Union Road Federation...
