Washington Post: Economist Robert Pindyck of the Massachusetts Institute of Technology recently examined the computer models that estimate the effects and costs of climate change -- and he didn't like what he found. The models reflect two gaping uncertainties, he says. First, we don't know how much increased atmospheric carbon dioxide (CO2) will raise global temperatures. "There are feedback loops' -- interactions between greenhouse gases and weather -- "that aren't easy to measure.' The models make assumptions....

Tiny algae signal big changes for warming Arctic lakes

Mongabay: The mighty polar bear has long been the poster child for the effects of global warming in the Arctic, but the microscopic diatom tells an equally powerful story. Diatoms are a type of algae that form the base of the food chain in watery habitats the world over. Disturbances among lake diatoms have exposed the impacts of rapid warming in the Hudson Bay Lowlands of eastern Canada, researchers reported Oct. 9 in the Proceedings of the Royal Society B.

Global warming might not be on hiatus, after all

HNGN: Many researchers believe global warming has slowed to a halt; but the heat may have just been hiding. Climate data only covers about 84 percent of the planet because many Polar regions and areas of Africa are largely undocumented, a University of York news release reported. Researchers decided to reconstruct the missing temperatures using satellites and data from weather stations and ships. The team predicted that global warming in the Arctics is happening eight times faster than anywhere...
Australias Politics of Global Warming

New York Times: Huge clumps of strange, pink-stringed jellyfish drifted into the protected bay near my home in Sydney last year. Thousands swarmed under the surface, stinging indiscriminately. I swam through them in a full-body wet suit for several long months with my swimming group, wondering if warmer currents had changed the habitat patterns. Scientists are now talking about a peculiar jellification of the sea, prompted by climate change. We smeared ointments on our faces and packed antihistamines and creams...

'Missing heat' discovery prompts new estimate global warming: Arctic warming fast
2013-11-13 15:59:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: An interdisciplinary team of researchers say they have found 'missing heat' in the climate system, casting doubt on suggestions that global warming has slowed or stopped over the past decade. Observational data on which climate records are based cover only 84 per cent of the planet -- with Polar regions and parts of Africa largely excluded. Now Dr Kevin Cowtan, a computational scientist at the University of York, and Robert Way, a cryosphere specialist and PhD student at the University of Ottawa,...
