No one says the insolation will cancel the man-made global warming. But neither does the man-made global warming stop everything and prevent the earth from entering the ice age period.The point I get is that natural insolation will not be cancelling the impacts of man-made global warming. Another point is in the tittle: ice age, interrupted. Compare with:
Tate's "ice age" (defined by the presence of ice caps) is ending. Because of us. -- Olivier5
So your article agrees with me, or rather, my take on CC is far closer to current science than Tate's crypto-denialism. — Olivier5
It's good to insert what-if scenarios, but let's deal with what's real right now. It's not broken yet, let's deal with that.As for metronomes... sometimes they break. Gime a sledgehammer and a metronome, and I'll show you how it might happen. The metronome is our climate, the sledgehammer is greenhouse gases. — Olivier5
This is a report on a computer model. — Tate
If ice sheets and glaciers don't melt a bit in the summer, the ice accumulates and starts to advance—in past ice ages, sheets of ice covered all of Canada and most of the Northern United States.
I cannot comment on the computer model, but my argument is that this is very very bad news, not good news. — unenlightened
Ya think?but my argument is that this is very very bad news, not good news. — unenlightened
But it cannot go on indefinitely so as to stop the glacial cycle. — L'éléphant
Icebergs. That's why. Icebergs breaking away and migrating farther to other oceans and melting, causing changes in oceanic patterns which then causes the oceans to absorb excess CO2 from the atmosphere. The resulting cooling effect triggers the ice age.I don't see why not. — Olivier5

At current melt rate the northern hemisphere won't have any permanent ice by 2040, 2050 at the latest. — Olivier5
Firstly, the Wikipedia statement doesn't even make sense. Secondly, the cited articles don't support it. That Wikipedia article is going to be edited. — Tate
"Sea ice" you should say; Greenland ice will take a little longer to melt, fortunately. — unenlightened
But wiki is better than clickbait. — unenlightened
We the planet should be so lucky to re-glaciate, preferably before the 2024 election. — Bitter Crank
That click bait article was referred to by the Wiki article.
I'll be using a range of articles from scientific publications. — Tate
Tate
Ah. Apologies; since you had just said that, I thought that it was one of your articles. — unenlightened
I'm not gonna ask for source on this. I'm not concerned about sources. I'm more concerned about the logic of what you're saying. If icebergs are breaking away from the ice sheet, then they are mobile. If they're mobile, they're drifting to the other oceans. And if they're going to those oceans, then they are cooling those oceans, like the Atlantic. Which is what we need to happen so the oceans can absorb CO2. The ice need to migrate to faraway oceans, and not just stay in the antarctic. The arctic apparently is enclosed, trapping its ice.At current melt rate the northern hemisphere won't have any permanent ice by 2040, 2050 at the latest. — Olivier5
The gist of the OP seems to be that global warming maybe just what the doctor ordered for the coming ice age. Hot + Cold = Just right (re Goldilocks & the 3 bears). — Agent Smith
Actually the OP doesn't say that at all. — Tate
I read between the lines! Perhaps an overactive imagination. Apologies, I'm into conspiracy theories! :blush: — Agent Smith
Let's not do that, ok? — Tate
I don't know, this thread has not gone anywhere in millions of years of discussion. Maybe a good conspiracy theory could liven it up a bit. — Metaphysician Undercover
The Drake passage opened 33.9 million years ago (the Eocene-Oligocene transition), severing Antarctica from South America. The Antarctic Circumpolar Current could then flow through it, isolating Antarctica from warm waters and triggering the formation of its huge ice sheets. — Tate
Whichever model winds up being most accurate, Dutton says it’s important to understand that the Antarctic ice sheet has an intrinsic tipping point.
“And there’s a real possibility we’re very close to it,” she says. “And we need to do everything in our power to prevent that from happening.”
I wonder if the tipping point they're talking about is where the loss of Antarctica's albedo effect causes positive feedback on warming. — Tate
