NEW YORK – Hurricane Harvey has left in its wake upended lives and enormous property damage, estimated by some at $150-180 billion. But the storm that pummeled the Texas coast for the better part of a week also raises deep questions about the United States’ economic system and politics.
It is ironic, of course, that an event so related to climate change would occur in a state that is home to so many climate-change deniers – and where the economy depends so heavily on the fossil fuels that drive global warming. Of course, no particular climate event can be directly related to the increase in greenhouse gases in the atmosphere. But scientists have long predicted that such increases would boost not only average temperatures, but also weather variability – and especially the occurrence of extreme events such as Hurricane Harvey. As the Intergovernmental Panel on Climate Change concluded several years ago, “There is evidence that some extremes have changed as a result of anthropogenic influences, including increases in atmospheric concentrations of greenhouse gases.” Astrophysicist Adam Frank succinctly explained: “greater warmth means more moisture in the air which means stronger precipitation.”
To be sure, Houston and Texas could not have done much by themselves about the increase in greenhouse gases, though they could have taken a more active role in pushing for strong climate policies. But local and state authorities could have done a far better job preparing for such events, which hit the area with some frequency.
