| Last year global levels of atmospheric CO2, the primary driver of global climate change, increased by 0.6 pct, or 19 billion tons. In addition methane rose by 27 million tons after nearly a decade with little or no increase. The burning of coal, oil, and gas, is the primary source of increasing CO2 emissions. Oceans, vegetation, and soils soak up half of these emissions. The rest stays in the air for centuries. |
