Washington - New US government figures show the amount of heat-trapping carbon dioxide (CO2) in the air jumped dramatically in 2012, making it very unlikely that global warming can be limited to another 2°C. Many governments set a 2° increase as the upper limit.

US government scientists report that CO2 levels jumped by 2.67 parts per million for a total of just under 395 parts per million compared to 2011.

That's the second highest rise in carbon emissions since records started being kept in 1959. Only 1998 had a bigger increase.

Scientists say hopes of limiting warming to 2° are fading away to almost nothing.
