2,400 delegates from 180 nations met in Bonn, Germany for preparatory talks under the UN Framework Convention on Climate Change (UNFCCC). The meetings were intended to shorten the huge 200-page draft negotiating text outlining options for combating global warming.

The main stumbling blocks include level and source of financial support and scale of emission reductions. Poor countries want support for mitigation and adaptation to come from developed nations since they are historically responsible for climate change.

Industrialize countries have tabled emission reduction pledges of 15 to 21 percent below 1990 levels, which will not stop global warming from surpassing the critical 2 degree Celsius threshold.
