PNAS Report (Might as well die)
Aug 16^th, 2019 at 9:06am

PNAS claims that global warming is feeding into other geophysical processes that aren’t directly related to carbon dioxide emissions, such as the mass release of methane from permafrost melting.

Goodbye Jumbo

So this convergence is producing what PNAS calls a “Hothouse Earth,” where global warming comes on so suddenly that it is no longer directly related to the capitalist burning of fossil fuels and...and there would be no way to contain it.

Hey porcupine I see you're back to your usual self promoting global warming paraphernalia.

Don't worry love we're not going to die and I'm sure whatever is going to happen has already happened before as we all know climate change is real and never ending.

So don't go jumping of a bridge any time soon, it will be all for nothing.

Look at that, everybody. Koch-funded tool Ajax has himself a map that makes no sense and doesn't explain god damn thing.

Nevermind how permafrost contains huge quantities of organic matter which sequesters carbon that has been frozen in place for thousands of years and that the rapid thawing and consequent decomposition of this organic matter would release vast amounts of methane, contributing significantly to the greenhouse effect warming the atmosphere already resulting from the burning of fossil fuels.

No, forget because Ajax has a map that doesn't explain a single god damn thing

Also nevermind that tis rapid thawing sets up another positive-feedback loop; increasing the greenhouse effect leads to more rapid and extensive permafrost melting, releasing more methane, in turn intensifying the greenhouse effect, thus further accelerating permafrost melting, and so on.

How could they have been "tropical" when the Antarctic is not in the same latitude?

As the bigot turns...stupid hippie.

You didn't do history or geography?

Antarctica was once part of Pangaea.

"THE world’s ultimate jigsaw puzzle will be missing a couple of pieces when it is next put together. A Pangaea-like supercontinent is forecast to form in 250 million years, but a new model predicts that superplumes rising from hotspots deep in the Earth’s mantle will keep South America and Antarctica from re-merging with the other continents.

Supercontinents form, break apart, then form again every few hundred million years. Geophysicists have traced the process back to early in Earth’s history by measuring magnetic fields in ancient rocks, and some have attempted to extrapolate from the present motion of the plates the likely shape of the next supercontinent."

https://www.newscientist.com/article/mg21128304-400-the-next-pangaea-will-have-p...

So according to the model it can't ever be tropical again. Of course models have been known to be wrong. Wink

What is there to suggest that it didn't occur the same way in all past similar events, basic logic would say that it is an unavoidable consequence of excessive warming ?
