Even weak tropical cyclones have grown more intense worldwide – we tracked 30 years of them using currents

In analyzing those records, we found that the ocean currents induced by weak tropical cyclones became stronger globally during the 1991-2020 period. We calculated that the increase in ocean currents corresponds to a 15% to 21% increase in the intensity of weak tropical cyclones, and that intensification occurred in all ocean basins.

We also found evidence of increasing intensity in the changes in water temperatures measured by satellites. When a tropical cyclone travels through the ocean, it draws energy from the warm surface water and churns the water layers below, leaving a footprint of colder water in its wake. Stronger tropical cyclones bring more cold water from the subsurface to the surface ocean, leading to a stronger cooling in the ocean surface.

The 2022 Atlantic hurricane season officially ends on Nov. 30, after 14 named storms and eight hurricanes. It isn’t clear how rising global temperatures will effect the number of tropical cyclones that form, but our findings suggest that coastal communities need to be better prepared for increased intensity in those that do form and a concurrent rise in sea level in the future.

I've not seen anything to indicate that renewables have a problem with frequency regulation and syncing with the grid they're feeding into. Hell, you can get synchronous inverters and generators for personal boats now.

... and more than about 20% "renewables" is all the networks can absorb before they become unstable.

A 20% contribution from renewable technologies that are barely 30 years old. At a lower per-watt cost than coal. Pretty amazing. Keep watching.

If they cannot overcome the problem now how will they do it at higher penetrations?

Do you seriously doubt that such problems are solvable?

From a reputable source.

And the biggest problem and the one the folks promulgating the "renewables" solution appear to be ignorant about are the economics (But then they are either profiteers, who tend to be fairly morals deficient or who favor solutions which, historically, have never been demonstrated to work)

Tassy Hydro have demonstrated what it takes to make a "renewables" system work and it eventually required solar, wind, inertia wheels, batteries and, they still needed to retain the old diesel generator system as backup. Since there's only 1,300 people using the system the scaling required to make this work for the entire country will have a horrendous cost and probably bankrupt us for eternity.

I'm a big fan if conservation and since the nuclearization of the extant system only requires replacing the boilers it's go nuke or go broke.

Good post - the evidence keeps piling up. But the deniers and trolls have changed their tactics now. They did the "no such thing as ACC" gig as long as they could get away with it. They were wrong, but want you to forget about that. Now, they switch to "but it's hopeless - you can't fix it" shtick. This will probably work better for them in propping up the fossil fuel industry.
All technologies involve risk - they won't all work out as hoped. But some end up working better than hoped. No matter - the deniers sit on their duffs and peddle their "nothing will work - it is hopeless" nonsense while the engineers and inventors work hard, take risks, and will likely end up saving our planet. We just have to say it - denialists of some form are always among us; not leading, not following, just getting in the way.

That one unique example doesn't scale up any better than my sailboat scales up to a containership. Repeating it doesn't make it realistic. Give it up, already.

A week or two ago some guy at the UN said that to meet their climate goals in the desired time frame they needed 5 trillion a year.
Wonder how they'll get it, I guess just print it, or get it from China, right.
Meanwhile back at the ranch, (I mean Italy,) maybe they know something that others don't.

Apparently BOM has recently found that the two adjustments of the temperature records was not doing the job in their new maximums for temperatures and they have made another adjustment.

If you cannot play the ball, play the man.

As someone who spent almost their entire working life looking for oil and gas I can reliably inform you that it's going to run out and it may be faster than you think now that politically powerful ratbags are discouraging exploration. Couple that with the environmental damage we do in burning coal to generate electricity and that consequently we need to stop doing it, one can make a very good case for transitioning away from fossil fuels.

"Renewables" are a mugs game (What does the slang mug mean? (1) : fool, blockhead. (2) : a person easily deceived. : punk, thug) and allowing politicians to design electrical power networks from sales brochures is another.

Go nuke.

Renewables will and can work and in some countries are close to working already. The next 10 years Will demonstrate it can work long term and financially correctly

Nuclear is too much a political hot potato to work widespread

Wasn't it just last year that the Panic was.. OMG.. The Atlantic circular current is slowing and may stop..
Upwelling caused by natural phenomena is part of the ecological cycle, the cold water brings up the nutrients that feed the microorganisms that feed the krill, that feed the whales and sprats that feed the fish that feed the cod and tuna that feed people.
Its funny how the drivers of renewables never scream about the abuse of nature and the need to drive conservation.. its always driving towards more tech and more profits..
Makes one wonder about agenda's.. mind, some of us wondered that about Covid and guess what..
Same ole voices..

Wow, I must have been taught incorrectly in Philosophy 101 Logic. Apparently if a person says one thing that is incorrect, everything they say is incorrect? Wow, that would make everything so much simpler if I could completely dismiss what some people say.
And now we know that one of the deniers on this thread actually works/worked in the fossil fuel industry. Hilarious - I should have known.
Will it really help an ACC thread to weave in COVID conspiracies and denialism?

Philosophy 101 Logic..
One person denying another person's denial = 2 Deniers.
I've nothing against so called renewables as I have been using 12v wind generators since the 80's but, they are only part of the solution.. does the world contain enough materials/minerals to build enough renewables for an 8 billion and growing population.
Nuclear is an essential and fossil needs tapering not cutting dead by politicians going for the populist vote.. remember the big Go Diesel con than was fostered on us a coupla decades back.. cheap cleaner fuel and cars they said..
That didn't last long.. diesel now costs more than gas both as fuel and cars yet both are cheaper to produce.
Maybe if you were less of an attack dog you'd get a pat on the head once in a while..

[boatman61]

As far as weaving in Covid..
Its the same fear mongering and denial of any other alternatives than the current politically and profits driven agenda..
SFA to do with the good of Humanity.. Pfizer was the only Good vaccine, everything else will either kill you or is useless.
Didn't see anyone on here lobbying for free Patents for the Third World..
Mind.. if that had happened there'd possibly be 636,440,663 or so more people to find energy for..
