U.S. still by far the largest per capita emitter of greenhouse gases
By Summit Voice
FRISCO — As delegates to the COP 18 climate talks in Doha, Qatar struggle to find agreement on basic issues — like how to account accurately for greenhouse gas emissions — the Global Carbon Project is reporting that carbon dioxide emissions will climb by 2.6 percent in 2012 to reach a record high of 35.6 billion tons in 2012.
FRISCO — With temperatures in polar regions rising twice as fast as the global average, there’s a good chance that between 30 to 85 percent of near-surface permafrost could melt, releasing billions of tons of carbon into the atmosphere by the end of the century.
But most existing climate models don’t accurately account for the impact of permafrost carbon dioxide and methane emissions, according to a new report from the United Nations Environment Program. The report recommends that the IPCC compile a special assessment report on permafrost. It also recommends that nations with extensive permafrost create national monitoring networks and make plans to mitigate the risks of thawing permafrost. These nations include Russia, Canada, China, and the United States.
