Greenhouse gas cuts 'not enough' to curb warming: UN
Countries will have to make far greater cuts in greenhouse gas emissions if the world is to limit the rise in global temperatures to two degrees Celsius or less, the UN has warned.
Commitments made since December's Copenhagen climate conference have been insufficient, the United Nations Environment Programme (Unep) said in a report at its annual meeting on the Indonesian island of Bali.
"No one should assume that the pledges will be enough," Unep director Adrian Steiner said.
"Countries will have to be far more ambitious in cutting greenhouse gas emissions if the world is to curb a rise in global temperature."
The Copenhagen summit struck a last-minute compromise that set a goal of limiting warming to two degrees Celsius (3.6 degrees Fahrenheit) and pledged a total of nearly 30 billion dollars in aid to poor countries by 2012.
