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.

Really wish some extreme actions were being taken. Shit like: everyone can trade in their gas cars for electric ones.

i agree, but how would we produce that many electric cars in a green way fast and with what money? focus on developing public transit and cities designed around bike lanes and local industry with a heavy emission tax to pay for it would be a better idea imo

That isn't nearly extreme enough. Electric cars are a weak half measure that fails to really deal with the problem. Investment in public transport, heavier taxation on personal transport, overhauling of energy generation, complete restructuring if global supply chains. These are the kind of changes we need.

We at the personal level need to accept that there is no way to continue with our lives exactly as they are and just make little tweaks like, oh you plug in your car now! Simple! No, a lot more needs to change. Our diets, the things we can buy, how easy it is to get unusual goods, the speed with which they reach us... where and how we can travel. These all need to change in major ways.

Extreme actions are being taken. Conservatives are trying harder than ever to increase oil and gas production, to de-list protected territories and wetlands and to defeat any remaining environmental protectiins that still somehow exist. They are succeeding to the extreme.

Conservatives are delighted they are entering a win-condition against life on earth. Their corporate overlords will reward them with golden crumbs in these final days.

The silver lining is, while we may have all lost the ability to live long lives, we haven't lost the ability to make conservatives suffer for killing us all.

Electric are only trying to save the car industry, not us:

I can't afford an electric car that has the range to get to work, and my 20 year old cars aren't worth much
