Global warming projected to rise due to record 'high level' of carbon emissions
It is increasingly unlikely that global warming will be kept below an increase of two degree centigrade (3.6F) above pre-industrial levels, a study has revealed.
Data show that globally CO2 emissions in 2012 hit 35.6 billion tonnes, a 2.6 percent increase from 2011 and 58 percent above 1990 levels.
The researchers said that emissions are the largest contributor to future climate change and a strong indicator of potential future warming, the BBC reports.
According to the report, many low-lying nations have used the UN conference, which is currently underway in Doha, to call for a threshold temperature rise less than 2C, arguing that even a 2C rise will jeopardize their future.
"These latest figures come amidst climate talks in Doha, but with emissions continuing to grow, it's as if no-one is listening to the scientific community," Corinne Le Quere, director of the Tyndall Centre for Climate Change Research at the University of East Anglia, said.
The researchers' paper said that the average increases in global CO2 levels were 1.9 percent in the 1980s, 1.0 percent in the 1990, but 3.1 percent since 2000, the report said.
The report estimated that carbon dioxide (CO2) accounted for 85 percent of the 'radiative forcing' that led to global temperature rises, the report added.
