Latest NASA global temperature data.
Earth has never been hotter since Homo sapiens (we) discovered agriculture in the early Holocene. Likely even since the Eemian interglacial 120.000 years ago.
Fossil coal, oil and gas emissions caused it.
We need to stop making it worse.
We can if we want to.

we can if we do!!!
Yet another graph of surface temps that contradicts other graphs.
2024 is more than 1.5°C warmer since the last ice age.
The Corridor of civilization life is -0.5°C to 0.5°C

in this hypothetical instance, how long (just a ballpark estimate) co2 would stabilise and then decline?
50 years then centuries?
is there any recent article exploring this "after the peak" development?
He ignores tipping points...like altered ENSO in the referenced paper
He ignores other planetary boundaries, irreversible
He isn't worth including in these discussions frankly.
The uncertainties about carbon sinks and tipping points mean there is no way to make the claims he makes.
Further, were he correct, the timeline makes his claim irrelevant to life as we know it.
Ditch Mann, Go Potsdam.
Perhaps tech bros should abandon genAI and fund studies for this new earth
Land and ocean sinks have altered already in ways poorly acctd for. Amazon is 3% more deforestation away from a tipping point. Boreal forests, ice melt, Ag all worse than thought. The C cycle alteration changes the math here. And we aren't sure about how badly.
Turn Mann/Hayhoe off, they are causing harm.

Version that's written more simply that I like reading for myself: https://kids.frontiersin.org/articles/10.3389/frym.2023.1248929
So yeah, we are the generation that will set the pace. we can't shut up now.
This is a very long terraforming process.
And despite promises, we have no coping mechanism to sustain a fossil fuel based growth.
True there are technologies that would solve the problem.
But it's a gigantic Lego kit that no one wants to put together.
And we end up dying
Or it’s a runaway greenhouse effect that we never get control of again, and the Earth becomes uninhabitable.
Which, you know, would be bad.
