Here's the reality of global warming

From the Seattle PI: "What a difference one degree of global warming makes!" "A new report says climate change is accelerating much faster than expected. The "Copenhagen Diagnosis," which took a year to complete, is a synthesis of hundreds of research papers about human-induced climate change that have been published since the most recent assessment by the Intergovernmental Panel on Climate Change in 2007. The new report says that satellite and direct measurements show:

• Greenland and Antarctic ice sheets are losing mass and contributing to sea level rise at an increasing rate.
• Arctic sea ice has melted far beyond the expectations of climate models.
• Sea level has risen more than 2 inches in the last 15 years, about 80 percent more than expected, and could rise 3 to 6.5 feet by the end of the century.
• Carbon dioxide emissions from fossil fuels in 2008 were about 40 percent higher than in 1990.

"This report shows that, contrary to the claims of 'skeptics,' the scientific community actually underestimated both the magnitude and the rate of global climate change," said Edward Miles, a UW professor of marine affairs and director of the Pacific Northwest Climate Impacts Group at the UW.

"In addition, since 2005 the growth in fossil fuel emissions exceeds the worst-case scenarios of the Intergovernmental Panel on Climate Change, demonstrating clearly that world population growth and increasing demands for fossil fuels from the developing world are now a major driver of climate change," said Miles, who was not involved in preparing "The Copenhagen Diagnosis."
