It has been known for some time that hurricanes need warm-enough surface temperatures in the oceans in order to form. The critical temperature turns out to be 26.5°C or 79.7°F.

Climate change is increasing sea temperatures, and even a few degrees matters.

In 2017 the exceptionally high surface temperatures in the Gulf of Mexico that launched Hurricanes Harvey, Irma and Maria were measured at 32°C or 89.6°F.

There have been many suggestions for cooling surface temperatures enough to prevent hurricanes from forming, but they have all seemed impractical.

Until now.

The Norwegians have long stopped ice forming in their fjords by efficient “bubble curtains” - bubbles of compressed air blown from perforated pipes, bringing relatively warm water from depths to the surface. Their scientists have pointed out that the system could be used for the opposite effect, bringing cooler water from (ideally) 100 meters to 150 meters below the surface to reduce the surface temperatures.

The first site for a real test may be the Yucatán Straits, which connect the Caribbean Sea to the Gulf of Mexico.

Reversing climate change, if it can happen at all, is a long term prospect.

When set against the enormous costs of destructive hurricanes, this idea for an interim solution may prove to be both practical and cost-effective. If you're interested in the idea and its progress, you will find many reports on it if you click the image above.

“The Universe is made of protons, neutrons, electrons and morons”
Animals can't believe the stupidity of people who deny climate change

The USA's current administration (but only a minority of its people and States) is, to put it bluntly, anti-science and anti-truth, possibly for related reasons, as well as anti-environment (for some mix of oil greed, corporate lobbying, stupidity and vindictiveness against anything Obama accomplished). We still have to see whether raging fires, floods and a succession of Category 5 hurricanes will put a dent in all this - but the three links above about the US Administration are very sobering, to put it mildly.

My younger daughter produced the wonderful face-palm montage above, for a different reason, and I thought it was too good not to snaffle. Hurricane Irma is the second Category 5 storm to hit the south-east USA this year, where it regained strength after passing over record-warm seas, and Texas is still suffering flooding with toxic water in the aftermath of Hurricane Harvey, with other strong hurricanes brewing.

Since extreme weather is not a new thing, the question keeps coming up: “Is our weather getting worse?”

The best answer to that in 2012 was Channel 4's super documentary, which can't be ignored today. I captured it in an article which you can find here, or click my summary image below.
Global warming and climate change - is our weather getting worse?

Oxfordshire Skies, 9th September 2017 (as Hurricane Irma hit Florida)

While in communication with relatives in Florida, luckily all safe now, we were staying in a self-catering converted barn in the Cotswolds. We experienced unsettled cold weather, with sudden cloudbursts that turned streets into trainer-deep streams, and also some impressive skies like these (possibly the remnants of Hurricane Harvey).

Maybe the planet is trying to tell us something?
