It's common knowledge that we have known about the greenhouse effect since the late 19th century. Having started Andrea Wulf's "The Invention of Nature" about Alexander von Humboldt, its interesting to read that he observed human activity changing climate as well as destroying ecosystems and tried to warn of the risk at the very beginning of that century.

Good thing we paid attention and rapidly learned not to trash the planet, eh?

When nature is perceived as a web, its vulnerability also becomes obvious. Everything hangs together. If one thread is pulled, the whole tapestry may unravel. After he saw the devastating environmental effects of colonial plantations at Lake Valencia in Venezuela in 1800, Humboldt became the first scientist to talk about harmful human-induced climate change. Deforestation there had made the land barren, water levels of the lake were falling and with the disappearance of brushwood torrential rains had washed away the soils on the surrounding mountain slopes. Humboldt was the first to explain the forest’s ability to enrich the atmosphere with moisture and its cooling effect, as well as its importance for water retention and protection against soil erosion. He warned that humans were meddling with the climate and that this could have an unforeseen impact on ‘future generations’.

Why did I do this today? Because of the ZEC calculation I mention in #1 .
The Zero Emissions Commitment = how much warming can be expected after CO2zero.

That 10 year lag after a CO2 pulse would locate the span for ZEC at 10 years.
@MichaelEMann says in this conversation with the director of #DontLookUp , that the oceans are going to keep taking up lots of CO2 for quite a while – which, he says, counters the warming tail and shortens it. redgreenandblue.org/2022/01/19

My chart above says: there is no warming tail.

And my assumption in #1 says: if the weakening AMOC leads to less and less ocean CO2 uptake, like the paper states, our continued emissions, should they continue, increase the CO2 growth peaks.
But that's not going to directly immediately changing the amplitude of the °C anomaly, as I found out in my chart above.

Okay.
Now to the thing I had actually planned for today: plotting Antarctic CO2 and Greenland's local temperature from before the Younger Dryas.

I despair. Again.

“BP to slash green investment and ramp up gas and oil” bbc.com/news/articles/c3374ekd

My main takeaway is that oil companies make obscene returns from extracting a natural “resource” no-one can truly own (160% profit? WTAF!?) and they and their shareholders place greed above the whole of humanity. I realise this is not news. So, roll on the apocalypse because yay money!
