LONDON (AP) — A U.N.-backed study has found that the world needs to cut by more than half its production of coal, oil and gas in the coming decade to maintain a chance of keeping global warming from reaching dangerous levels. The report published Wednesday by the U.N. Environment Program noted that many governments have made ambitious pledges to curb greenhouse gas emissions. But it found they are still planning to extract double the amount of fossil fuels in 2030 than what would be consistent with the goal of keeping global temperature rise below 1.5 degrees Celsius (2.7 degrees Fahrenheit). Climate experts say the world must drastically reduce the burning of fossil fuels as soon as possible.
