Oops! hazel,

is there no way to convert the thermal energy (from the oceans - implied, see post #38) into electrical energy?

Looks like the context got lost and this turned into a general rather than specific question.
Thanks to all contributors, I think I'll give this topic a rest for now. I'm an old geezer who'll probably be dead and gone by the time humanity screws the planet over which unfortunately looks like it may be sooner rather than later!
Ca' Canny A'budy and Play Bonny!

Coincidentally, the Arctic sea ice extent yesterday dropped to the record low value for the first time in this melting season.

There's some interesting ideas like the gas powered fridge & (valve)radio. But none of them lose heat overall. Global warming is the problem, but any fix has to reduce Global warming.
And with Siberian Methane in the mix with methane from cattle, and the Amazon rainforest being so rapidly taken out of the mix, the earth is entering a positive feedback loop. Those who say it can be fixed are dreaming, imho. Even if the emitters stopped immediately, warming would still continue.

So Wildfires are now an everyday event. When we hear of wildfires these days, we glaze over. 'Yeah yeah, another 2000 acres, mountain and a few villages burned down. Where was it? Oh Lytton in Canada. 5000 acres in Oz? That's not much. (yawn).' It matters to folks more if a vineyard is burnt down.
We're the same with murders. In fact (giving my age away) as a kid, in the days of Narrow Wheelbase tractors, I was horrified by the first tractor overturning I heard of on radio. The narrow guage tractors were much taller than wide, so they would roll over 270º, ending on a side, usually killing the driver. But someone died nearly every day, and as I listened to the news more regularly, I noticed myself becoming immune to the tragedy of a family losing the breadwinner, and Dad. They banned narrow wheelbase tractors in the 1970s here.
And we have to glaze over in this world, because you need to insulate your sanity from the madness if you are to be much use to anybody.

I don't know if it is because of rising sea levels now or expected rises expected due to temps in the Pacific Northwest averaging well above 110F (I think Portland and Seattle had a few days in a row at 116F! - roughly 47C) but finally numerous municipalities and others are standing "in yer face" with Big Oil and spitting between their teeth "Yer taes oot".

Here's a good news story from today's news https://www.bbc.com/news/av/world-australia-57675513
Using algae, brewers turned the CO2 into oxygen.

I knew if I waited long enough someone would come up with a solution!

It's not a solution to warming. Too little, too late.

While all that is pretty comical, in all seriousness the planet doesn't need saving. It will be just fine. It's the current residents that seem to be in some danger.

That's an imortant point. When harmful viruses or bacteria multiply inside our bodies, we throw a fever to burn them out. It looks as if Mother Nature does the same.

IMHO fine is a relative term. Nature good or bad will adapt, survival of fittest will prevail. Ecosystems will survive or not but it will be a domino affect.

Did you get that "It will be just fine" from one of your ex-president's speeches? I don't really think you understand the full implications of what's going wrong now. Extinct species will continue to be extinct. Exhausted resources will continue to be exhausted. Melted ice will continue to be melted, and Antarctica melting will be the threat for future generations. We were the ones whose leaders had a chance to sort this, and our generation blew it.

And ... you miss the point. The planet will still be a planet, in a binary system third major orbit from a pretty unremarkable star. There will be a lot less LIFE on it, and that should concern US, but the planet itself will be just fine.
(And now you made me explain the joke and just ruined it. Oh well..)
I think there is still time to take control of this. IT will not be without pain, but there is still time to adjust things so humanity can survive. It is not, however, time for contemplation. We must act and act effectively. EVERY effective act will help, but NOT acting will ensure a greater disaster. (We have long passed the point where we could totally avoid disaster. The objective now must be to limit the damage.)

Where did "Ice Ages" come from? How did the oceans rise high enough to flood what is now the heartland of the United States?
Did mankind even exist then? Were there any cows, and if so were any of them farting?
Why has the River Thames in London frozen solid over twenty times on-record?
I kindly suggest that this planet still has many mysteries up its sleeves that we really have no idea even exist. Of course it is usual for us to take "inconvenient correlations" and to try to make sense of them, but I think that it's just hubris to assert that "we actually know."
It could very well be that these are perfectly-natural cycles caused by some mechanism which we presently cannot guess. I think that there's a lot to be said for tempering your pronouncements with: "But, on the other hand, we could be totally wrong."

The most convincing theory is that of Milankovich. He showed that the superimposition of several different astronomical cycles causes periodical vulnerability to ice ages. Whether an ice age actually materialises depends on whether at least one of the earth's poles can freeze over. This requires either a polar continent or a landlocked polar sea. We currently have the former at the south pole and the latter at the north pole, hence the sequence of glaciations that marked the early history of mankind. We are now technically in an interglacial. However man-made warming will break us out of the glacial epoch and send us careering into a hot phase.[/QUOTE]
