UN climate report urges end to fossil fuel emissions by 2100
COPENHAGEN, Denmark - Climate change is happening, it's almost entirely man's fault and limiting its impacts may require reducing greenhouse gas emissions to zero this century, the U.N.'s panel on climate science said Sunday. "We have the means to limit climate change," IPCC chairman Rajendra Pachauri said. "The solutions are many and allow for continued economic and human development. All we need is the will to change, which we trust will be motivated by knowledge and an understanding of the science of climate change." The report released Sunday caps its latest assessment, a mega-review of 30,000 climate change studies that establishes with 95-percent certainty that nearly all warming seen since the 1950s is man-made. Today only a small minority of scientists challenge the mainstream conclusion that climate change is linked to human activity. The reports must be approved both by scientists and governments, which means political issues from U.N. climate negotiations, which are nearing a 2015 deadline for a global agreement, inevitably affect the outcome. The report is meant as a scientific roadmap for the U.N. climate negotiations, which continue next month in Lima, Peru. The IPCC carefully avoided taking sides in that discussion, saying the risks of climate change "Are generally greater for disadvantaged people and communities in countries at all levels of development."
