Ocean-measuring satellite launched
A French-US satellite, which will provide the most accurate monitoring ever of rising sea levels and track the effects of climate change, was launched into orbit on Friday from a California base. A rocket carrying the Jason 2 satellite took off from Vandenberg Air Force base. Jason 2 is a 510kg oceanography space lab designed to provide precise monitoring of rising sea levels and currents, which are among the most serious consequences of global warming.
