Climate change causing US wildfire season to last longer, Congress told

Guardian: America's wildfire season lasts two months longer than it did 40 years ago and burns up twice as much land as it did in those earlier days because of the hotter, drier conditions produced by climate change, the country's forest service chief told Congress on Tuesday. But the forest service was forced to make sharp cuts to fire prevention programmes, and reduce the numbers of fire-fighters and engines because of budget pressures, Thomas Tidwell, the chief of the United States Forest Service, told...

Climate change, Arctic amplification, Jet stream causing Extreme weather

Bay Area Indymedia: "An important part of the global air motion in the mid-latitudes of the Earth normally takes the form of waves wandering around the planet, oscillating between the tropical and the Arctic regions. So when they swing up, these waves suck warm air from the tropics to Europe, Russia, or the US, and when they swing down, they do the same thing with cold air from the Arctic," explains lead author Vladimir Petoukhov. "What we found is that during several recent extreme weather events these planetary...

Commercial fishing and climate change causing shrinking fish sizes
2013-01-31 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Radio Australia: A new study by Australia's peak scientific body, the CSIRO, shows that fish around the world are shrinking in size. Commercial fishing and climate change are believed to be the main culprits behind the decrease in body size. But CSIRO scientists say the shrinking size is also leading to a drop in fish populations with smaller fish more susceptible to predators. Correspondent: Jennifer Macey Speakers: Dr Asta Audzijonyte, CSIRO marine and atmopheric research unit; Professor Jessica Meeuwig,...

Climate change causing headaches for winemakers

Bloomberg: Terraced vineyards meander along the Douro River in Portugal. The hillsides allow Port producers to plant in higher or lower elevations depending on weather. (Fladgate Partnership Vinhos S.A)To paraphrase Shakespeare, in the vineyards of the world, something worrisome this way comes. 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?
2013-01-01 18:53:00| Climate Ark Climate Change & Global Warming Newsfeed
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...
