Environment ministers from over 180 nations gathered on Friday in Nairobi, Kenya to mark the end of a two-week UN climate summit. Delegates agreed to review the Kyoto Protocol in 2008 in order to expand the fight against global warming beyond 2012.

The UN Framework Convention on Climate Change (UNFCCC) gathered over 6,000 delegates to focus on issues such as adaptation to climate change and different methods of transferring climate change technology. Fast growing industrial nations like China and India will be able to join the Kyoto pact in 2012 when the first period of the deal comes to a close.

The summit is the offspring of the 1992 Rio Summit, which highlighted the need to belt the rising effects of global warming. The Kyoto protocol was created to try to tackle problems with the fossil-fuel gases that cause this problem. At the 1997 Kyoto gathering, a pact was agreed to by all participating 35 industrial nations to reduce emissions of greenhouse gases by 5 percent below 1990 levels by 2012.

The United States has been a notable holdout. President George Bush opposed the agreement, saying it would damage the U.S. economy and should have obliged poorer countries as well. US currently accounts for 20 percent of the world's greenhouse emissions.

The following annual UNFCCC meeting will be held in Indonesia from December 3-14, 2007.
