IPCC: SAFE AMOUNT OF CARBON IS LESS THAN STORED IN WORLD'S FOSSIL FUELS
The Intergovernmental Panel on Climate Change released its fifth assessment last week, saying that without sustained and substantial reductions in greenhouse gas emissions the world is likely to see a 1.5C increase in temperatures above pre-industrial levels, and that climate change's effects will continue for several hundred years even if emissions are reduced. The report also warned that the amount of carbon the world can burn without heading for dangerous levels of warming is "much less than the carbon stored in fossil fuel reserves." The report stated that the oceans have become warmer, absorbing 90 percent of the extra heat energy accumulated between 1971 and 2010. A co-chair of the working group warned that extreme weather events are more likely. "Heatwaves are very likely to occur more frequently and last longer. As the Earth warms, we expect to see currently wet regions receiving more rainfall, and dry regions receiving less," he said. Meanwhile, a large freighter sailed through the Arctic Northwest Passage for the first time last week, as climate change opens much desired routes. The ship sailed from Vancouver to Finland, on a route that's 1,000 nautical miles shorter than shipping through the Panama Canal.
