The IPCC's key findings were agreed to unanimously by more than 130 governments, including those of the United States, China, India, and the European Union, and now are forming the basis for international policy. For the first time since its first assessment in 1990--and I repeat, 1990--the IPCC concluded that there is at least a 90-percent chance that manmade activities, through the burning of fossil fuels, are the major cause of global warming. Now, if we were told in any sphere that we had at least a 90-percent chance of diverting a disaster through changes we ourselves could make, would we not take action? Is the IPCC finding not a compelling reason to assume reasonable steps when climate change is occurring, even beyond the projections that were outlined just decades ago? So here on these charts we have some illustrations of just what the science is referring to: Arctic sea ice from NASA's images taken in 1979, 2005, and again in 2007 displaying the increase in the melting of the polar ice in September when the sea ice is usually at a minimum each year.
