Climate - truthful information about climate, related activism and politics.

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 the author of the article provided significant input into the drafting of what became the Inflation Reduction Act.

I'm cranky but yeah that's easy to do for a wealthy home-owning car-owning Californian. Would love to do what this person has done but I'll never own a home so ๐Ÿคทโ€โ™‚๏ธ

100% energy independence is the dream.

As an aside, utilities/private companies shouldn't be allowed to influence energy policy. Since they're trying to maximize profits they have a disincentive to support things that would be good for the public like residential solar and cleaner but capital intensive upgrades to infrastructure.

I don't think I'm trying to go there. You get better reliability more cheaply when transmission can move electricity from where the sun shines or the wind blows to where people are.

Wind turbines are also a lot more cost-effective when they're bigger, so things like community ownership of a few big turbines is a better choice than each household owning their own little one.

I agree, something like the municipal internet model for energy would be a great alternative. To clarify, I think energy independence will only be a viable option for the masses if storage technology advances enough to allow for days/weeks of backup power, but one can still dream.
