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 overall message here I think is: action is still necessary, but the reality is that we're too caught up in politics and economics and we missed our chance at mitigation. Now we need to look to how to cope with what's coming.

We can't stop the sun from growing so anything we do here on earth is ultimately meaningless.

Eventually there will be a heat death of the universe, so that technically makes all existence 'meaningless' if you consider an ending to make everything before it meaningless.

Before then though, there will be a lot of existing going on for living beings, who fill their lives with meaning and joy and connection while they remain alive, and we'd rather like it if our environment wasn't a complete garbage fire while doing so.

You can make any question existential enough to void everything of meaning. Nobody cares about being effortlessly technically correct, they care about effort to correct something immediately material and consequential. "We're all gonna die so who cares?" Is the doomerist get out of jail free card to excuse being a part of, or a tool of those creating the problem. May as well not voice any opinion at all, because it won't be remembered forever. May as well just commit suicide because your relationships and your ultimate impact on the world and humanity through your existence is pointless because The Universe will end at some impossibly distant point in the future beyond what we can even pretend to understand as a scale of time. What a useful observation.

Technically, we can. We probably will be able to do that a few hundred years from now and a few hundred years is nothing to something like the sun
