April 13, 2014 - What would it take to rein in climate change? A new U.N. report says the answer entails a massive shift to clean energy and possibly more drastic measures.
A rapid shift to less-polluting energy will be needed to avoid catastrophic global warming, because global emissions of heat-trapping greenhouse gases have accelerated to unprecedented levels, the United Nations reports today.
These emissions — largely from the burning of oil, gas and coal — grew more quickly between 2000 and 2010 than in any of the three previous decades and will need to be slashed 40% to 70% by mid-century and almost entirely by century's end to keep global temperatures from spiraling out of control, according to a landmark report by the U.N. Intergovernmental Panel on Climate Change.
Even those emissions cuts might not be enough. The IPCC report, striking a particularly urgent one, says countries might even need to enlist controversial technologies that remove carbon dioxide from the atmosphere. read more>>>
