The scientists working on the IPCC assessments have carefully documented observed changes in air temperature, ocean temperature, ice retreat, and sea level rise since the past century.

For example, the latest (fifth) assessment report from the U.N.'s Intergovernmental Panel on Climate Change (IPCC) projects that the global average sea level rise over the course of the 21st century would be in the range of 10 to 32 inches, with a mean value of about 19 inches.

The obsession with average sea level rise compared with other coastal hazards (increases in water levels driven by storms as well as tsunamis) is a good illustration of how the focus on climate change is distorting assessments of risks and hazards.

At the Copenhagen conference in December 2009 the Director of the U.S. Navy Task Force on Climate Change, Rear Admiral David Titley gave a somber assessment of the risks presented by climate change, including the likely need for greater humanitarian and disaster relief missions, and the dangers posed by such «wild cards» as ocean acidification and rising sea lChange, Rear Admiral David Titley gave a somber assessment of the risks presented by climate change, including the likely need for greater humanitarian and disaster relief missions, and the dangers posed by such «wild cards» as ocean acidification and rising sea lchange, including the likely need for greater humanitarian and disaster relief missions, and the dangers posed by such «wild cards» as ocean acidification and rising sea levels.
