Roger Pielke on Hurricanes and Human Choice:
Another danger: Public discussion of disasters risks being taken over by the climate lobby and its allies, who exploit every extreme event to argue for action on energy policy. In New York this week, Gov. Andrew Cuomo declared: "I think at this point it is undeniable but that we have a higher frequency of these extreme weather situations and we're going to have to deal with it." New York Mayor Michael Bloomberg spoke similarly.
Humans do affect the climate system, and it is indeed important to take action on energy policy—but to connect energy policy and disasters makes little scientific or policy sense. There are no signs that human-caused climate change has increased the toll of recent disasters, as even the most recent extreme-event report of the Intergovernmental Panel on Climate Change finds. And even under the assumptions of the IPCC, changes to energy policies wouldn't have a discernible impact on future disasters for the better part of a century or more.
The only strategies that will help us effectively prepare for future disasters are those that have succeeded in the past: strategic land use, structural protection, and effective forecasts, warnings and evacuations. That is the real lesson of Sandy.
