Heads in the Rising Tide


Officials from the state of Florida seem to have their heads in the sand (and other places); sand that is likely to be swept from their very own Florida shores as sea levels rise. However, surely climate change could be an eventual positive for Florida: think warmer climate and huge urban swathes underwater — a great new Floridian theme park! But, remember, don’t talk about it. I suppose officials will soon be looking for a contemporary version of King Canute to help them out of this watery pickle.

From Wired:

The oceans are slowly overtaking Florida. Ancient reefs of mollusk and coral off the present-day coasts are dying. Annual extremes in hot and cold, wet and dry, are becoming more pronounced. Women and men of science have investigated, and a great majority agree upon a culprit. In the outside world, this culprit has a name, but within the borders of Florida, it does not. According to a  Miami Herald investigation, the state Department of Environmental Protection has since 2010 had an unwritten policy prohibiting the use of some well-understood phrases for the meteorological phenomena slowly drowning America’s weirdest-shaped state. It’s … that thing where burning too much fossil fuel puts certain molecules into a certain atmosphere, disrupting a certain planetary ecosystem. You know what we’re talking about. We know you know. They know we know you know. But are we allowed to talk about … you know? No. Not in Florida. It must not be spoken of. Ever.

Unless … you could, maybe, type around it? It’s worth a shot.

The cyclone slowdown

It has been nine years since Florida was hit by a proper hurricane. Could that be a coincidence? Sure. Or it could be because of … something. A nameless, voiceless something. A feeling, like a pricking-of-thumbs, this confluence-of-chemistry-and-atmospheric-energy-over-time. If so, this anonymous dreadfulness would, scientists say, lead to a drier middle layer of atmosphere over the ocean. Because water vapor stores energy, this dry air will suffocate all but the most energetic baby storms. “So the general thinking, is that that as [redacted] levels increase, it ultimately won’t have an effect on the number of storms,” says Jim Kossin, a scientist who studies, oh, how about “things-that-happen-in-the-atmosphere-over-long-time-periods” at the National Centers for Environmental Information. “However, there is a lot of evidence that if a storm does form, it has a chance of getting very strong.”

Storms darken the sky

Hurricanes are powered by energy in the sea. And as cold and warm currents thread around the globe, storms go through natural, decades-long cycles of high-to-low intensity. “There is a natural 40-to-60-year oscillation in what sea surface temperatures are doing, and this is driven by ocean-wide currents that move on very slow time scales,” says Kossin, who has authored reports for the Intergovernmental Panel on, well, let’s just call it Chemical-and-Thermodynamic-Alterations-to-Long-Term-Atmospheric-Conditions. But in recent years, storms have become stronger than that natural cycle would otherwise predict. Kossin says that many in his field agree that while the natural churning of the ocean is behind this increasing intensity, other forces are at work. Darker, more sinister forces, like thermodynamics. Possibly even chemistry. No one knows for sure. Anyway, storms are getting less frequent, but stronger. It’s an eldritch tale of unspeakable horror, maybe.
