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 main problem I see with all this is that change will move at the speed of the economy and finances ... companies and businesses will wait to see if someone or something will come along that will make a ton of money quickly and easily while also doing something for the environment and that people like. None of the investors will actively go out to encourage anyone to develop this magical unicorn business. They will all just wait around to see it appear on a stock ticker and give them promise of profit.

The only solution like that would be something like carbon capture and investors put a lot of money into that. To not emit as much, we need to deploy a lot of different solutions. Those however replace old ones, which means old industry is fighting hard to stop it.
