California Joins 12-State Climate Change Agreement Ahead Of 2015 UN Conference In Paris
2015-05-20 09:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Business Times: California has joined a pact with 11 other states and countries to slash greenhouse gas emissions and tackle climate change. Gov. Jerry Brown signed an agreement Tuesday as part of a broader effort to pressure global leaders to adopt an aggressive emissions treaty at a United Nations-led summit in Paris later this year. This global challenge requires bold action on the part of governments everywhere, Brown said in a statement. Its time to be decisive. Its time to act. The 12-member agreement...

Climate change could cause cold-blooded animals' thermal tolerance to shrink
2015-05-20 05:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Cold-blooded animals can tolerate body temperatures only a few degrees above their normal high temperatures before they overheat, which could be a problem as the planet itself warms, according to San Francisco State University researchers. Ectotherms such as fish, reptiles and insects can stretch their body's tolerance of high and low temperatures a little bit at each extreme, but that stretch, or plasticity, is relatively small, the scientists found. As a result, the animals will see their "thermal...

California, international leaders sign climate change agreement
2015-05-20 00:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: California and leaders of 11 states and provinces signed an agreement on Tuesday to limit their output of heat-trapping greenhouse gases 80 to 95 percent by 2050, a goal they hope will help prevent runaway climate change. The target, which is based on a 1990 benchmark, will allow the individual governments, which collectively represent more than $4.5 trillion in GDP and 100 million people, to tailor reduction plans to fit their regional needs. Called "Under 2 MOU" for a Memorandum of Understanding...

Climate change could be a threat to electricity supply in Western US
2015-05-19 22:29:00| Climate Ark Climate Change & Global Warming Newsfeed
Verge: Droughts and high temperatures caused by climate change could play havoc with the electricity supply of the Western United States, say engineers in a study published in Nature Climate Change. As of 2010, more than 90 percent of America's electricity is generated by thermoelectric power stations -- facilities that use heat to create electricity, from burning coal to nuclear power. Many plant like this, however, rely on water for cooling, with these facilities accounting for 45 percent of water withdrawals...
Coal & climate change: a death sentence for the Great Barrier Reef
2015-05-19 22:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Conservation: Back in 1999, I made an upsetting discovery. By comparing the temperature tolerance of reef-building corals with the projected effects of rising carbon dioxide levels, I found that the oceans would soon grow too warm for corals to bear, meaning that coral-dominated systems like the Great Barrier Reef would disappear within 30-40 years. Much as I tried to find a mistake in my reasoning and calculations, the numbers kept telling me that one of the worlds most diverse ecosystems would disappear...
