New study states that climate change may not be reversible

17 nations are responsible for 80 percent of the world's carbon emissions

The threat of global warming is quite an immediate one, having a potential to not only cause irreparable damage to global ecology but also, if left unchecked, to make the planet earth unliveable. Visible effects of global warming have already been felt, with scientists recently collating data on the rise in sea levels because of global warming, noting the increase to be around 11 millimeters. Of course the issue of whether or not the effects of global warming climate change can be reversed has been a hotly contested subject for many years now with conventional wisdom urging that regardless of the damage done so far, carbon emissions, which contribute directly to global warming, must be cut down upon.

However a new study suggests that perhaps it is too late, that carbon emissions are now too high for humanity to turn back the tide of climate change. Researchers at the Tyndall Centre for Climate Change Research at the University of East Anglia in Britain have found that it is unlikely that global warming, which stands at 2C above pre-industrial levels, will ever be reverted, saying that carbon emissions had gone beyond a level to control.

The research, published in the journal, Nature Climate Change stated that carbon dioxide emissions had reached 35.6 billion tons this year, an increase of 2.6 percent from last year and an alarming 58 percent increase since the 1990s.

Tyndall's director, Corinne Le Quere, said, "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. I am worried that the risks of dangerous climate change are too high on our current emissions trajectory. We need a radical plan."

The study found that even though in recent years there had been urgent calls to cut down on CO2 emissions, the year 2000 onward saw the most average increase with 3.1 percent compared to 1 percent in 1990 and 1.9 percent in the 1980s. Seconding these results were figures posted by the World Meteorological Organization (WMO) which stated that CO2 emissions had hit a new high in 2011, according to its annual Greenhouse Gas Bulletin. The report stated that carbon dioxide levels had reached 391 parts per million in 2011 alone and that CO2 emissions were responsible for 85 percent of global warming.
