The Terrible Toll of Typhoon Haiyan Doesn't Excuse Bad Policy

The terrible toll of Typhoon Haiyan—estimated to have
killed more than 4,000 people—reminds us of the often awesome power of the weather.
Some say the death and destruction in Asia are symptoms of climate change and
that we can expect worse to come—unless we cut back on emissions of greenhouse
gases. Coincidentally, negotiators from around the world are meeting in Warsaw,
Poland this week and next to attempt to hammer out a deal that would do just
that. But cuts in emissions of greenhouse gases may not be the best way to
address the threat of hurricanes and typhoons, even if climate change is making
them worse.
When it hit the Gulf of Leyte in the Philippines, Haiyan
had sustained winds of 145 mph, with gusts of up to 170 mph, making it
comparable in intensity to the Great Galveston Hurricane of 1900, which had
winds of approximately 145 mph at landfall on the Texas Coast. The loss of life
in Leyte, currently estimated at between 3,600 and 4,500, may ultimately be as
great or greater than Galveston, where between 8,000 and 12,000—a quarter of
the town’s population—are estimated to have died, making it the most deadly
natural disaster in U.S. history.
Some activists claim that Haiyan is a symptom of climate
change and that it should be a wake-up call to take action to cut emissions of
greenhouse gases. Even theologians are getting in on the act, saying that the
typhoon is the result of the sin of climate denial! But those may not be the
most appropriate lessons. First, because it is far from clear that global
warming is leading to an increase in the number or intensity of typhoons and
hurricanes. Second, and more importantly, even if global warming does result in
more extreme weather events, cutting emissions will likely do little to reduce
the damage they inflict, while potentially costing a great deal, thereby
reducing people’s ability to take preventative or ameliorative action….
