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.

I'll note that for most purposes, when people talk about going to 2°C above what it was in the late 1800s, they usually are talking about the long-term average, not one-day events.

Ah yes. If we all had a boat load of cash to just install solar panels and buy other shit to make things more green... But oh wait. We don't have that kind of cash in today's economy...

... because all that money is already allocated to the oil industry and the weapons it needs to keep going. If only there was some solution.

Also the problem isn't actually solar panels but grid storage, which itself would be significantly less of a problem if we didn't keep dumping money in to cars and car-centric infrastructure.

Most people don't realize that divesting from cars wouldn't take a massive investment but would actually be much cheaper. Parking minimums and suburbs are completely unsustainable. Building bike infrastructure is cheaper than maintaining car infrastructure, and it allows for increased density that increases property values and increases local tax revenue. Cars are massively subsidized, from direct subsidies to the auto and oil industries, to infrastructure like free parking, to all billions in Oil wars. We could literally just stop doing things that hurt us and come out ahead.

It's like we're smoking and making up excuses about how we can't afford to quit.

I live in mandatory car land. The older I get, the more I hate driving and dealing with insurance, traffic, registration, maintenance, fuel, and inspections.

Money spent generally = emissions.

It is cheaper to be greener in many cases. Pork/chicken/turkey/rice+beans are cheaper than beef. Gas sippers are cheaper than canyoneros and monster trucks. Bicycles, transit, and shoes are cheaper than cars. Reasonable housing is cheaper than a McMansion.
