Investing in Climate Change Mitigation

Investors must treat the crisis as an economy-wide threat? No. Investors have money, and they can use it however and wherever they think will do them the most good, whether that means monetary profit or the satisfaction of doing what’s good for the world, or some combination of the two.
The investment world hasn’t responded decisively? Again, no. Think of all the money that’s going into decarbonizing our transportation and energy sectors. That means alternative fuel (especially electric) cars and trucks, renewable energy, and nuclear.
It’s all fairly impressive, especially considering that the fossil fuels industries essentially own the U.S. law-making processes. This group of gargantuan corporations are ~125 years old, enormously profitable, and receive 7+ trillion dollars (worldwide) of subsidies annually. They use our atmosphere are their own private sewer, and no one even thinks about asking them to pay to clean up after themselves.
$7 trillion is a lot of money, regardless of your standard, which makes the article linked above from the International Monetary Fund worth your time.
Another issue here is improving our use of land, which basically translates into moving away from beef, so as to enable us to stop destroying the Amazon rainforest. As anyone could have guessed, however, the financial pressures here are analogous to those in fossil fuels, where the industry is putting a full-court press against plant-based and lab-grown meat, and has declared an all-out PR war.
Taking into consideration the economic pressures being applied by the industry incumbents, clean tech is actually doing fairly well. But will its progress be sufficient to avert catastrophe?
No one knows.
Maybe the answer depends on how people like you and me react and get involved.

It pains me to think that I live among Americans who are this stupid. This country has 880 million acres of farmland, and 34,000 acres of solar PV. That’s a ratio of 26K:1.
The New Yorker’s Andy Borowitz notes: If this comment doesn’t cinch the Peace Prize for him the Nobels are rigged.
In this day of utter confusion and the mincing of words, it’s good that we have a person in the U.S. Congress like Jasmine Crockett. The harsh reality is that it was a terrible idea to elect a criminal thug to lead the most powerful country on the planet, and she is perfectly willing to put this in plain language.
Points to be made here include:
If you can recognize the photo here, you’re at least 65 years old, probably 70+. It’s a small generator that converted some of the kinetic energy from your moving bicycle’s tires into the electrical energy required to power your headlight.
What makes the evil presence of Donald Trump so horrific in our lives is his amazing capacity to harness the “herd instinct” that Bertrand Russell identified.
Re: the reader’s comment here on The Grapes of Wrath, there is no doubt that the book challenges the basic tenets of capitalism, and it does so in what is perhaps the most forceful piece ever written in the English language.
The claim here, i.e., that the MAGA folks “believe in nothing” is incorrect, if only because of the trust they place in the infallibility of Donald Trump.
Yesterday I had the pleasure of meeting a woman from Ireland who had come here for a wedding.
