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.

Just keep in mind these kinds of investments nearly always underperform the market. So it'll be a hit to your portfolio. It's up to you if you're willing to make that tradee off.

I don't care at all as long as it's not below inflation.

I have my super with australian ethical and banking with great southern bank, but I'm sure both still invest in israeli companies and the like. If anyone have better suggestions I'd love to hear. From my researches I couldn't find much.

I'm much more worried about helping criminals get richer than to make a profit.

Are you talking about sustainable/ethical investments? Because that's straight up incorrect, on average sustainable funds (often called ESG for "ethical, social, governance") outperform the market. Commonwealth bank, one of Australia's big four banks would not be making this move to end loans to the fossil fuel industry if it was genuinely going to impact their bottom line.

Their bottom line might improve with the publicity they get for cutting off the fossil fuel companies. We don't even know how much they got from those anyway. They might not be giving up much.

And ESGs can outperform in some years. But over the long term (10+ years), and with the increased management fees, they don't.

The vanguard ESGV fund is, I think, similar to a total-market index fund but with fossil fuels removed, and it only has a very slight increase in management fees compared to their standard index funds (I think it's expense ratio is 0.09).

However, like many index funds, it's invested heavily into Nvidia, Google, Meta, Amazon, Tesla, Microsoft, Apple, etc. So a lot of that investment money isn't going to ethical companies, and if the AI bubble pops, those funds will be hit fairly hard (along with the whole market).
