BERLIN (AP) — The U.N.'s expert panel on climate change says necessity and reality don't match when it comes to reducing greenhouse gases to combat global warming.
The Intergovernmental Panel on Climate Change says right now, global emissions are actually on the rise, though they need to drop by 40-70 percent by 2050 to keep the global temperature rise below 2-degrees C (3.6-degree F).
On average global emissions rose by 1 gigaton a year between 2000 and 2010, outpacing growth in previous decades to reach "unprecedented levels" despite some efforts to contain them.
The panel didn't get into who should do what in the 33-page summary.
Leaked drafts of a larger document showed the biggest reason for the rising emissions is the higher energy needs resulting from population growth and expanding economies.
