Global greenhouse-gas emissions already have passed the point where the worst effects of global warming could be averted, and they are still rising, according to the third annual United Nations report on the so-called emissions gap.
Some countries have made pledges to help reverse this trend by lowering their emissions. However, the report by the U.N. Environment Programme warns that the gap between these pledges and reductions necessary to cap average global warming at 2 degrees Celsius (3.6 degrees Fahrenheit) by 2020 continues to widen.
“In addition we have one year less to close it,” said Niklas Höhne, one of the UNEP report’s lead authors.
