Don't be such a pessimist. There are plenty of people who want climate action and are prepared to sacrifice for it. We can also demand more from our governments without blaming individuals. My government keeps approving new coal and gas plants with reckless abandon even though they could easily be wind or solar. We're allowed to demand more action from them.

Ehh, I started riding a bike and edging toward veganism to reduce my footprint, but it definitely feels like I'm in the minority. And I live in CA, which should be the leader in all of this, sadly.

It's getting better. But way too slowly.

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.
