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.

Carbon capture company emits more than it captures (climateandcapitalism.com)

Between April 2021 and October 2024, British physicist Michael de Podesta paid £40 per month to carbon capture company Climeworks. In return, the company promised to remove 50 kilograms of carbon dioxide each month. But in September 2024, de Podesta wrote that “when I checked the other day they had removed precisely no CO₂ from the atmosphere”.

The following day, de Podesta wrote, “I conclude that I am indeed a gullible idiot.”

Climateworks’ business model involves selling carbon credits for CO₂ that it hopes to capture in the future

Good scam if you can convince people...so have they convinced anyone

Microsoft, UBS, Morgan Stanley, Stripe, Shopify, British Airways, Lego, Swiss Air, PwC, and TikTok.

Oh /s

I guess "in the future" is a promise you can always give, like "free beeer tomorrow"

There is absolutely no way to remove carbon from the atmosphere in quantities that will make any kind of difference. The only thing we can do is to stop polluting. This does not start with cars, it starts with cruise ships and industry. And since we all know that will never fucking , just celebrate the end of the world.

Honestly, I don’t even know why the sub exists.

Seconded. Plant life has spent hundreds of millions of years perfecting carbon capture. We're so cocky as a species, thinking we can speed-run terraform tech and that might somehow allow us to continue our culture of constant growth without consequence.

Relying on carbon capture to fix climate change is like calling in a construction company to rebuild your house while it's still actively on fire.

Probably worth trying though?

We can concentrate energy way better than plants can, so the possibility is there. The problem is that as Climateworks is a private company, they are not releasing the data that might help others.
