New UN Climate Report = we've hit 'tipping-points'

Could it be natural climate change does not have human caused options?

1) All the forests on Earth = one ( 1) world forest equivalency ( wfe ).
2) Anthropogenic greenhouse gases added to the atmosphere each year are equivalent to burning all the forests down, fifteen times over
3) An annual forest fire larger than the entire surface of the planet. Land and oceans combined.
4) A fire that large cannot happen naturally, due to the fact that we have only one (wfe).
5) Naturally, burning all the forests down, plus all 130-active volcanoes going off each year, couldn't remotely touch man's impact.
--------------------------------------------------------------------------------------
6) There isn't a single organism on the planet which has the ability to 'evolve' at a pace equal to that of climate change in order to 'adapt.'
7) 'Climate sensitivity', a measure of global warming with a doubling of the atmospheric concentration is calculated at a temperature at which humans will become extinct.
8) 5-Million humans died of 'heat-death' last year.
9) We put more carbon in the atmosphere last year than ever before.
10) It's a mathematical certainty that we're inviting our own extinction.
11) The timescale is dependent upon what we do.
12) And we haven't mentioned positive feedback mechanisms, which are already in play.

So nothing that nature hasn't already done through a super Volcano.

1) I'd parse it out on a 'pre-industrial', more technology- void context.
2) The old-world cut its forests down to build & burn until they had a timber crisis.
3) Then they switched to coal, to burn and make brick for construction, since the wood was gone, or came to the New World to cut it down and burn it, or both.
4) The coal mines flooded, which led to a national competition for a water pumps to clear the mines.
5) Which led to quality cylinders and pistons.
6) Which led to the Newcomen engine.
7) Which was improved by Watt, leading to exponential growth in steam power.
8) Which is where carbon dioxide really started taking off.
----------------------------------------------------------------------------------
9) Without the industrial revolution, we'd never have had mechanized agriculture or artificial fertilizer, and populations would have been constrained by Thomas Malthus calculus.
10) The middle class wouldn't exist as we know it, and some inventions would never have gotten traction, as they need the discretionary spending of a middle class to take hold.
11) No modern medicine.
-------------------------------------------------------------------------------------
12) 'Natural' climate change would move on Milankovich-cycle velocity time-scales, nothing like what we're doing.
13) And nothing as complex, as Earth's 'chemistry' would be 'feral.'

Now you're talkin'!
My brother lives in one in Nevada, and even here, in North Texas, when Yellowstone caldera goes, no one around here will be around to talk about it.
I don't think humans have been on Earth during one of these episodes.
They're certainly capable of altering the climate according to the paleorecord.
Explosive eruptions, reported since writing was invented, and investigated by volcanologists are reported not to have altered the weather for more than 4-years or so.
This is where the concept of 'nuclear winter' and 'global-cooling' originated.
Benjamin Franklin wrote about it, and is credited with the invention of the 'parasol-effect' we're experiencing right now, with coal-fired power-plant, sulfur-dioxide aerosols cooling the entire planet.
When 'Frankenstein' was written by Mary Shelley, she was vacationing during the 'year without a summer.' Mount Agung had erupted in what is now the Indonesian archipelago, and it cooled the whole planet for two years before all it's ash rained out.

Go to NASA's website, they'll provide you with the models and specifications for the required supercomputers.

They went thataway {points both directions]

I'd equate Simulation theory to Maya

https://www.hinduwebsite.com › hinduism › essays › maya.asp
Maya is a state of existence, a point of view, caused by the imperfect discriminating intelligence (buddhi), which according to Hindu scriptures, is an aspect of Prakriti and the nearest in the hierarchy to the pure consciousness. From that limited perspective we experience duality and plurality.

3) Neither ( anthropogenic greenhouse gas) - induced global warming, or climate change are natural phenomena.
4) What humans do with the information is not germane to climate science.

I fail to follow this.

Younger Dryas. All previous human civilizations' traces have been obliterated by churn.

1) Go to NASA's website and see what you can find.
2) I read 'books!' You'll find the citation on page- 420, of David Wooten's book, 'The Invention of Science.'
3) The Younger Dryas isn't associated with super-volcanos as far as I can remember.

[freebeard]

Supervolcano is a subset of Catastrophism. Apologys if I over-generalized.

Would you find an interloper from the Oort Cloud or a micro-nova more likely?

You'll find the citation on page- 420,

I see what you did there.

I'm not going to revisit any space-based conversations. You guys ----- me off so much with the S-O ---- I swore I'd never give it another thought.
I've left all my space stuff at home and that's where it'll stay.
I'm sure you already know that all asteroids are actively monitored.
I don't believe in micro-nova.

[oil pan 4]

Micro-Nova have been observed coming from lone M-class stars like the sun. The micro-Nova has a lot more evidence than man made global warming.
