Climate - truthful information about climate, related activism and politics.

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.

We were supposed to hit peak emissions. Why won’t they stop rising? (www.vox.com)

I hear your concerns, man. But a cursory look at the current science behind how we describe things like BOE and Clathrate Gun don’t leave us with mere years between now and instant hotpot catastrophe.

I don’t think it’s useful (if your goal is to promote the mitigation of these events and a livable world for future generations) to catastrophise at that pitch and make it sound like we’re fucked.

We’re not fucked. Things are going to get a lot harder. A lot harder. Much badness. But we’re not fucked. There’s room to work here. And we need to start doing a LOT of work without making it sound like starting wouldn’t do us any good.

I get that you have hope, but magical thinking isn't going to fix this unless you are literally capable of magic or you have a time machine powered by positive thoughts or something.

We are already globally over capacity on fresh water. Crops are already failing. The earth is already at heat storage capacity. Carbon emissions are still rising. Population numbers are still rising. Capitalist industry is still posting record profits.

Most people won't even consider a vegan diet and campaigning for community gardens and bike lanes isn't going to magically increase the heat storage capacity of the oceans.

So I am genuinely asking you, mitigation of resourse depletion, works how? Mitigation of thermodynamics works how?

What type of hard work do you think can fix this?
