UN: Emissions Vows Not Enough to Avoid Targeted Rise
A new United Nations study says carbon cuts pledged in the Copenhagen Accord can't keep the world from warming more than 2 degrees Celsius.
The study was released today at the UN Environment Programme meeting in Indonesia.
Widely used climate models predict devastating impacts if the global mean temperature rises more than 2 degrees.
But new UN modeling says pledges made in the accord will fall, at best, 500 megatons short of cutting carbon enough by 2020 to meet the temperature goal.
UNEP Executive Director Achim Steiner says the world needs more aggressive measures, including big investment in reducing deforestation, possibly separate from any new global treaty.
He warned any such treaty has become more difficult to get since the failure in Copenhagen.
