Are terrorists more of a threat than slippery bathtubs?
Are terrorists more of a threat than slippery bathtubs?
President Barack Obama, er, slipped into hot water when The Atlantic reported that he frequently suggests to his staff that fear of terrorism is overblown, with Americans more likely to die from falls in tubs than from attacks by terrorists.
The timing was awkward, coming right before the Brussels bombings, but Obama is roughly right on his facts: 464 people drowned in the U.S. in tubs, sometimes after falls, in 2013, while 17 were killed here by terrorists in 2014 (the most recent years for which I could get figures). Of course, that’s not an argument for relaxing vigilance, for at some point terrorists will graduate from explosives to nuclear, chemical or biological weapons that could be far more devastating than even 9/11. But it is an argument for addressing global challenges a little more rationally.
The basic problem is this: The human brain evolved so that we systematically misjudge risks and how to respond to them.
Our visceral fear of terrorism has repeatedly led us to adopt policies that are expensive and counterproductive, such as the invasion of Iraq. We have ramped up the intelligence community so much that there are now seven times as many Americans with security clearances (4.5 million) as live in Washington, D.C. Meanwhile, Donald Trump responded to the Brussels attacks with crowd-pleasing calls for torture or barring Muslims that even Republican security experts agree are preposterous.
On the same day as the attacks, a paper by James E. Hansen and other climate experts was released arguing that carbon emissions are transforming our world far more quickly than expected, in ways that may inundate coastal cities and cause storms more horrendous than any in modern history. The response? A yawn.
Hansen is an eminent former NASA scientist, but he’s also an outlier in his timing forecasts, and I’m not qualified to judge whether he’s correct. Yet whatever the disagreement about the timeline, there is scientific consensus that emissions on our watch are transforming our globe for 10,000 years to come. As an important analysis in Nature Climate Change put it, “The next few decades offer a brief window of opportunity to minimize large-scale and potentially catastrophic climate change that will extend longer than the entire history of human civilization thus far.”
To put it another way, this year’s election choices may shape coastlines 10,000 years from now. Donald Trump and Ted Cruz have both mocked the idea of human-caused climate change, with Trump suggesting that it is a hoax invented by China to harm the American economy (he now says that last point was a joke).
The upshot is that Brussels survived this week’s terrorist attacks, but it may not survive climate change (much of the city is less than 100 feet above sea level).
Doesn’t it seem prudent to invest in efforts to avert not only shoe bombers but also the drowning of the world’s low-lying countries?
