The third report, which was expected to be formally announced later in the morning, makes clear the world must quickly embrace a basket of technological options - both already available and developing - just to keep the temperature rise to 3.6 degrees Fahrenheit.
Much of this week's debate has centered around how much it will cost to adopt greener policies.
China is facing increasing international pressure as its economy expands - it posted 11.1 percent growth in the first quarter - and it pumps increasing amounts of greenhouse gases into the atmosphere.
At this week's meeting, Beijing campaigned for wording that would clearly blame the top industrialized countries in North America and Europe for global warming and give them the responsibility for solving it, rather than latecomers like China and India, delegates said.
Chinese delegates did not discuss their positions publicly, but environmental activists suggested Thursday that China was being unfairly targeted, saying it was making strong efforts to improve energy efficiency and rein in emissions.
Stephan Singer, of the conservation group WWF International, said China had a worthy target of increasing energy efficiency by 20 percent from 2006 to 2010.
``It's a very ambitious target and I would wish many industrialized countries would have the same target,'' Singer told reporters.
The U.S. remained surprisingly quiet on most issues at the meeting, but some delegates said it appeared to be content letting China take the lead. However, the U.S. delegation was vocal over the role nuclear power could play in efforts to reduce greenhouse gasses. European nations reminded policymakers not to forget the security risks that could be associated with that.
The Independent (UK): Malaria fear as global warming increases
Published: 04 May 2007
Global warming could lead to a return of insect-borne diseases in Britain such as malaria, and increased incidence of skin cancer caused by exposure to the sun, a government report warns today.
With temperatures forecast to rise into the high 30s this summer, scientists fear Britain could be in line for at least one extreme heatwave before 2012. Tick-borne diseases are set to increase, along with the threat of other diseases associated with hotter climates.
The report by a group of scientists for the Department of Health updates earlier warnings that climate change could see heat-related deaths rise to more than 2,800 a year in Britain. Heatstroke claimed the lives of nearly 15,000 people in France in exceptional conditions in 2003, and today's report by the Department of Health warns that could be a taste of things to come in Britain.
The French deaths were caused when temperatures soared to 40C, but some forecasters have warned that Britain could be heading towards such temperatures as a result of the changing climate.
Last month was the hottest April on record and plants and wildlife are reacting to the hotter temperatures in a spring which has felt more like summer for many in the south of England.
The report comes as the UN's Intergovernmental Panel on Climate Change (IPCC) prepares to release highly controversial proposals for averting the worst consequences of global warming.
