Der Spiegel reports that the IPCC’s new draft report is backing off the claim of mass AGW-caused extinctions.
“There is very little confidence that models currently predict extinction risk accurately,” the report notes. Very low extinction rates despite considerable climate variability during past hundreds of thousands of years have led to concern that “forecasts for very high extinction rates due entirely to climate change may be overestimated.”
In the last assessment report, Climate Change 2007, the IPCC predicted that 20 to 30 percent of all animal and plant species faced a high risk for extinction should average global temperatures rise by 2 to 3 degrees Celsius… The current draft report says that scientific uncertainties have “become more apparent” since 2007.
How about that? As the research continues, we know more about what we don’t know. Anti-science types might not grasp that thisus an indicator of good science, and may jump on it as evidence that scientists don’t really know anything about climate change. I expect that. What I’m curious about is whether the acolytes who worship the IPCC reports like holy scripture will give this due notice or pretend it never happened?
