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.

The growing field of ​“firetech” is reinventing the age-old practice of prescribed burns and devising other novel methods of preventing and suppressing fires.

Humans are just so arrogant that they think they can fix nature. There's forests evolved together with fires. If you prevent fires, you can do more damage than good.

The carbon cycle evolved to be near enough to circular to not have run itself out of carbon in millions of years. It maintains this balance though changes in evolution that take tens of thousands of years minimum, not fifty. We’ve all but doubled the amount of carbon in the atmosphere, we need to get as much of it out as soon as possible or we know what will happen.

We’ve already done vast damage, and are well on our way to all but exterminating our reefs and a large slice of ocean life. That’s not can happen, that’s absolutely will happen unless we intervene. Much like with dams, the chance of some localized ecological damage is not just acceptable but a bargin compared to what doing without really means.

OK so? You didn't understand what I said. We're trying to fix the problem we caused by trying to change nature in unpredictable ways, with unpredictable consequences. Se need to focus on the root of the problem.

Nature isn't unpredictable. It's done the same thing forever. We are the ones fucking it up.

What's hard to predict are the consequences of us further messing with it. We always think we can just tweak things. Like fixing forest fires or seeding clouds of sulfur. We're just naive apes with fancy tools.

If we valued a homeostatic, intentional civilization we could be the immune system of the planet instead of the capitalistic cancer we currently are.

There are degrees of uncertainty, and there you don’t have to try a new, or in this case old, idea everywhere all at once. The problem is too mich carbon is in the air, getting as much of it out as quickly as practical is the priority. Nothing mentioned here seems to be at odds with cutting carbon emissions, so i don’t see why you seem to think that it’s one or the other.
