The Bottom Line on Global Warming
From ThinkProgress.org: Scientists and policymakers have generally settled on 2°C as the amount of global temperature increase, over pre-industrial levels, the climate can take without creating truly dangerous upheavals. Because the effect of carbon in the atmosphere is cumulative, staying below that threshold requires a hard limit on the amount of carbon the world emits between now and 2100. We’ve already blown through a bit over half of that “carbon budget.” Last week’s World Energy Outlook 2014 from the International Energy Agency (IEA) projects that , on our current course, we’ll chew through the rest by 2040. The bottom line is we cease all CO2 emissions by 2040, which won't happen. So 2 degrees Celsius is not going to happen. While IEA projects that renewables will grow aggressively between now and 2040, overtaking coal as the globe’s leading source of electricity, and that coal and oil use will effectively plateau by that point, fossil fuel use — and thus carbon emis...
