Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

How do I invest in green tech initiatives and companies? (fedia.io)

Trump is giving the world a very expensive lesson in fossil fuel dependence. Now is the time to invest in companies that are moving us towards this green future, but how?

ETFs are garbage, IMO. Supposedly "green" ETFs have polluters like Shell, Boeing, CrApple, Total, Transocean, and so much more. According to a report in 2021, 70% of companies in "sustainable" ETFs are "misaligned" aka greenwashing.

I found private investment / crowdfunding companies that allow ESG investments, but recently watched a video that the entire market (private equity in general) was heading off a cliff and to divest ASAP. It hasn't spooked me completely as it's just a video, but I need to do some research.

Regardless, these are the ones I found:

My questions to y'all: how do you invest in green tech? Can you recommend alternatives to the ones I named?

Private investment almost invariably has negative returns, and even ESG ETFs are sketchy as you note.

As others have written, for positive returns, focus on capital investments in your own life. I have a solar subscription with a 10% IRR and recently replaced my pool pump with a variable speed one: $2,000 installed that saves $300/annum with an average lifespan of ten years for an 8.1% IRR.

Go solar. Replace your gas heat with a heat pump. Install on demand or electric heat pump water heaters. Swap your gas car for an electic.

Vote both at the ballot and with your wallet against MAGA policies.
