Canada: Rising carbon emissions from oilsands a 'unique' challenge, federal cabinet told

CBC: Greenhouse gas emissions from increasing oilsands production will rise faster than Canada's ability to curb them, the federal government was warned before new emissions reduction targets were announced last week. Cabinet documents obtained by CBC News reveal the thinking behind the scenes as the cabinet members mulled over various proposals for Canada's target to cut its greenhouse emissions by 2030. The documents marked "secret" also suggest Canada should try to negotiate new North American-wide...

Energy subsidies top $6.6 trillion, lift carbon emissions by fifth: IMF study
2015-05-19 22:51:00| Climate Ark Climate Change & Global Warming Newsfeed
Age: The world subsidises energy consumption to the tune of more than $200,000 per second, with about 60 per cent of that going to support coal, according to researchers at the International Monetary Fund. In a paper published by the IMF, the authors found that energy subsidies are much more than previously estimated. These will rise to $US5.3 trillion ($6.6 trillion) in 2015, or about 6.5 per cent of total global output. For some developing nations, such as in the former Soviet Union and Pakistan,...
Shellfish species shrinking as rising carbon emissions hit marine life

Guardian: Sea creatures are set to shrink as the worlds oceans become more acidic. That is the startling warning given by an international group of biologists who have charted the likely impact of rising carbon dioxide levels on marine life. The group reveals that not only are hundreds of marine species likely to be wiped out as more and more carbon dioxide is dissolved in the Earths oceans but also that creatures that do survive in particular those with shells, such as clams, oysters and snails will...
Carbon emissions from peatlands may be less than expected

ScienceDaily: Duke University scientists have discovered a previously unknown dual mechanism that slows peat decay and may help reduce carbon dioxide emissions from peatlands during times of drought. "This discovery could hold the key to helping us find a way to significantly reduce the risk that increased drought and global warming will change Earth's peatlands from carbon sinks into carbon sources, as many scientists have feared," said Curtis J. Richardson, director of the Duke University Wetland Center and...

US carbon emissions are rising again. Can Obama push them back down?
2015-04-21 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Vox: One of the most promising climate-change stories of the last decade was the steep plunge in US carbon dioxide emissions after 2005. Before then, US emissions had been rising relentlessly for decades. Suddenly, they were falling. That drop was partly due to the US fracking boom, which created a glut of cheap natural gas and spurred utilities to burn less coal for electricity. It was partly due to various clean-energy and efficiency measures. And it was partly making real progress on global warming....
