Over the last decade, global warming has started affecting those narrow zones best suited for growing wine grapes. Warmer temperatures are a mixed blessing for winemakers. In colder climates like Bordeaux and Burgundy,...

Is Climate Change causing an exponential rate of Ice sheet Mass Loss, sea level rise?

Bay Area Indymedia: The thesis that Hansen has put forward for several years is that Ice Sheet collapse is a non-linear process: that with the inclusion of amplifying climate feedbacks it is likely to follow an exponential rate of acceleration - a doubling rate. It might be a 10 year doubling time, or less. This will lead to extensive sea level rise, perhaps in the order of 5 metres this century. But accurate data measurements of ice mass loss via laboriously estimating mass input and output has only been available...
