UN Secretary General Ban Ki-moon welcomed a new report outlining the serious effects of global warming, and urged governments to adopt prompt action to avert extreme weather and its effects on the world population, according to dpa. The report - the second of three instalments by the Intergovernmental Panel on Climate Change - was released in Brussels earlier Friday following years of study involving hundreds of scientists and government officials. "The impacts of climate change are increasingly noticeable, and likely to become more so in the future as extreme weather events intensify," Ban said in a statement. He called for "adequate, large-scale adaptation measures" without delay to counter some of the worst consequences predicted by the IPCC report. The UN has planned a summit to review the Convention on Climate Change to be held in Bali, Indonesia, in December, and make improvements before current provisions in the document are to expire in 2012. The conference would allow governments to devise new ways to fight global warming.
