Harvey Is What Climate Change Looks Like

In all of U.S. history, there’s never been a storm like Hurricane Harvey. That fact is increasingly clear, even though the rains are still falling and the water levels in Houston are still rising.

But there’s an uncomfortable point that, so far, everyone is skating around: We knew this would happen, decades ago. We knew this would happen, and we didn’t care. Now is the time to say it as loudly as possible: Harvey is what climate change looks like. More specifically, Harvey is what climate change looks like in a world that has decided, over and over, that it doesn’t want to take climate change seriously.

Houston has been sprawling out into the swamp for decades, largely unplanned and unzoned. Now, all that pavement has transformed the bayous into surging torrents and shunted Harvey’s floodwaters toward homes and businesses. Individually, each of these subdivisions or strip malls might have seemed like a good idea at the time, but in aggregate, they’ve converted the metro area into a flood factory. Houston, as it was before Harvey, will never be the same again.

…Climate change is making rainstorms everywhere worse, but particularly on the Gulf Coast. Since the 1950s, Houston has seen a 167 percent increase in the frequency of the most intense downpours. Climate scientist Kevin Trenberth thinks that as much as 30 percent of the rainfall from Harvey is attributable to human-caused global warming. That means Harvey is a storm decades in the making….

….The symbolism of the worst flooding disaster in U.S. history hitting the sprawled-out capital city of America’s oil industry is likely not lost on many. Institutionalized climate denial in our political system and climate denial by inaction by the rest of us have real consequences. They look like Houston.

Once Harvey’s floodwaters recede, the process will begin to imagine a New Houston, and that city will inevitably endure future mega-rainstorms as the world warms. The rebuilding process provides an opportunity to chart a new path. The choice isn’t between left and right, or denier and believer. The choice is between success and failure.
