Large Rise in CO2 Emissions Sounds Climate Change Alarm
2013-03-08 18:22:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Desk: The chances of the world holding temperature rises to 2C the level of global warming considered "safe" by scientists appear to be fading fast with US scientists reporting the second-greatest annual rise in CO2 emissions in 2012. Carbon dioxide levels measured at at Mauna Loa observatory in Hawaii jumped by 2.67 parts per million (ppm) in 2012 to 395ppm, said Pieter Tans, who leads the greenhouse gas measurement team for the US National Oceanic and Atmospheric Administration (NOAA). The record...

Climate change is making animals shrink
2013-03-08 13:52:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: Humans might adapt to climate change through some mixture of mitigation, adaptation, and suffering (like relocating Coney Island several miles into interior Brooklyn, or saying goodbye to chocolate). But the animal kingdom? Many species are already coping with rising temperatures by physically getting smaller [$ub req]. The reasons are complex and vary between species, but the CliffsNotes version is this: Animals (especially cold-blooded ones) often develop faster metabolisms in warmer temperatures,...

Warming Lakes: Climate Change Threatens the Ecological Stability of Lake Tanganyika

National Geographic: Tropical lakes in East Africa dont grab headlines the way polar bears do, but climate change is having an effect on them, too. Although the changes are not as visible as melting polar ice caps, they are no less real. As in many lakes around the world, water temperature is on the rise in Lake Tanganyika. This and other climate-related factors are causing subtle but significant changes that threaten the ecological stability of the lake and the livelihoods of people who depend on it. With air...

Australia links 'angry summer' to climate change at last
2013-03-07 12:29:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The hottest summer on record. The hottest January on record. The hottest day on record for Australia as a whole. Bushfires in every state and territory. Daily rainfall records and major flooding. Over a period of 90 days, these were some of the 123 extreme weather records broken during Australia's "angry summer". Despite the dramatic headlines and "flame-seared images" that documented extreme weather over the summer, the Australian media largely failed to make the link to climate change. Of 800...

Climate Change Might Open Up Northwest Passage to Shipping by 2050
2013-03-07 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Investigating what is sometimes seen as one of the more favorable effects of climate change, a pair of scientists from UCLA has done a careful analysis of the melting of Arctic sea ice and concluded that it could lead to ships traversing the ice-free Northwest Passage (NWP) by 2050. It would also lead to much shorter transit times through the existing North Sea Passage (NSR). These developments may greatly reduce the time and cost of shipping but would also lead to unforeseen economic and geopolitical...
