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 wish it gave me hope. I guess the only bright side is "we're trying, maybe, a little".

In another post a while back, someone (may have even been OP), said something to the effect of 'carbon capture is just social permission to keep using fossil fuels'. I think about that a lot, and definitely agree.

I would change this slightly to:

the idea of future carbon capture is just social permission to keep using fossil fuels right now'

Because of this it is in my opinion actually harmful. And don't even start thinking about who gets to shoulder potential future costs vs todays profits.
