Another enormously powerful storm is barreling towards the United States. Hurricane Florence is projected to strike the Carolinas and Georgia late this week, inflicting severe wind and storm surge damage. Just as dangerous is the projection that it will probably stall out near the coast, dumping most of its rain in a small area and causing massive flooding far inland — just as Hurricane Harvey did to Houston last year.

It is a terrifying and dangerous situation for residents of the affected states. In the longer term, it is also an object lesson for how conservative Republicans are failing the absolute most basic task of governance: representing the interests of their constituents. Republican policymakers have been twiddling their thumbs while a huge threat bears down on their states — if not actively making things worse.

Climate change is the unavoidable background for all major weather events now. While one can't pin any one event on it, there is decently strong suggestive evidence that climate change is making hurricanes more powerful and will continue to do so in the future. And as Robinson Meyer points out, there is initial evidence that it's slowing them down as well — thus making their flooding worse. Hurricanes have slowed by about 10 percent since 1949 across the world, and "a warmer world will have more stagnant, slow-moving air masses," he writes.

More important, the rising sea level (up four to eight inches and counting over the last century) is unquestionably caused by climate change, and will certainly badly worsen the flooding from Florence.

Of all the Republican state governments on the Eastern Seaboard, North Carolina's is probably the most irresponsible. As Jenavieve Hatch explains, six years ago the Republican majority in the state legislature in North Carolina passed a bill suppressing a report from the state's own experts warning of the risks of sea level rise:

A panel of scientists on the state Coastal Resources Commission issued a dire warning in March 2010, estimating that the sea levels along the state's coast would rise 39 inches over the next century. Conservative lawmakers and business interest groups feared the report would hurt lucrative real estate development on the state's coast and sought to undermine it … Conservative state Rep. Pat McElraft, whose top campaign contributors were the North Carolina Association of Realtors and the North Carolina Home Builders' Association, drafted a bill in response that rejected the panel's predictions.

The bill passed in 2012. It's classic American conservative policymaking — half taking dictation from big business, half science denial. The latter part is important, as no sensible real estate investor really wants to see his properties flooded or blasted down their foundations by gale-force winds. And now the bill for this awesome act of hubris and self-harm is going to arrive tomorrow — and I'd wager wealthy conservatives will be as affected as anyone.

South Carolina isn't quite so obviously self-harming as its neighbor, but that's about all that can be said for it. Its Republican state government and congressional delegation is filled with science deniers and people who automatically vote against any climate diplomacy or regulation. Meanwhile, Georgia's Gov. Nathan Deal (R) used to be a full-fledged climate denier in Congress (like the rest of the delegation), but has clammed up on the issue since becoming governor in 2011.

This sort of retreat from denial seems more and more common in conservative politics (perhaps driven by these clockwork extreme weather disasters), replaced mainly by a lot of evasion and double talk. But that is far from good enough. Just like Florida, the Carolinas and Georgia very badly need two things: a massive federal investment program to ruggedize their built environment and an all-out diplomatic push to secure an international agreement on climate policy. Local politicians won't even be able to properly help their own cities alone, much less conduct international diplomacy. The biggest greenhouse gas emitter by far these days is China, so any successful attack on climate change must be international, and hence must be led by the federal government.

Mainly this would mean mounting our own crash decarbonization program, and using that progress to challenge, help, and stimulate other such efforts. Ultimately China is just as doomed as Florida if climate change is not checked, which is why they are making heroic efforts to cut their emissions and build out their renewable sector.

The U.S. has a lot of power and wealth. We could be pulling our weight here, and helping our own citizenry in the process. But instead we're the worst laggard in the world. And when Trump pulled out of the Paris climate accords, virtually the entire Republican Party either cheered or kept quiet. The citizens of Georgia and the Carolinas — many of whom tried their hardest to get their representatives to pay attention to reality, it's important to note — are about to pay the price.
