How important is the climate change threat?

JP Morgan is putting $2.5 trillion into it.
A trillion here, a trillion there, pretty soon you're talking real money.
Topsoil restoration will take massive investment, too. No-till farming, "green manure, " etc.
It might be useful to pay attention to scientists who actually look at all aspects of climate change and have one warning to people like you and Josh:
“Stop using the worst-case scenario for climate warming as the most likely outcome.” https://www.nature.com/articles/d41586-020-00177-3
That has nothing to do with JPMs plans, or the farm article. Studies of soil loss are not done by the IPCC. I know one of the researchers at the University of Nebraska who contributed to the current estimate.
And scientists present multiple warming scenarios. If a shlock media outlet picks only the worst to report, that's sensation mongering, and not something I've supported here.
When I post here, I don't select the most dire scenario, and so am not really in need of your "warning."
A recent report of reputable climate scientists has pointed out that most estimates of where we'd be in 2020, made a couple decades ago, were actually overly conservative. Rates of pack ice and glacier melt, methane rise, fire incidence, habitat loss, etc were worse than initially expected. There seems to be an accelerated effect due to positive feedback.
A secret report?
Not really. First one I read was in Sci Am a few years ago....

https://www.vox.com/energy-and-environment/2019/12/4/20991315/climate-change-prediction-models-accurateSo, accurate on temps, too conservative on the
effects of that temperature rise average. If that distinction isn't clear, you can reread the articles. Googling "permafrost melting" is another possible way to see how feedback effects come into play, where you have ancient bogs thawing and releasing methane and carbon both. The general term "cryosphere" is handy in further understanding of how melting surfaces generally increase Earths absorption of heat. Ice is like a mirror, reflecting heat back into space. When it's melted, the resulting open land, or bog, or ocean, all become vastly better heat sinks.
