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.

China is winning on renewables. Will it win on green steel, too? While the U.S. backtracks on green steel commitments, Chinese companies are starting to make iron with hydrogen. (www.canarymedia.com)

reducing the environmental impact of human activities, redistributing income and wealth within and between countries, and encouraging a shift from materialistic values to a convivial and participatory society

I never said anything contrary to this. Reducing climate impact of energy is more important to human sustainability than local environment cleanliness, but certainly environment sustainability is also important. Degrowth is not needed. Taxes on pollution GHGs and polution (or better, regulatory obligation to clean up any) are. UBI in general and with those taxes as a specific funding component is great policy, and voluntary. Don't want to pay pollution or income taxes, then don't produce anything. Can still get rich from work, and letting UBI trickle back up to those who produce. UBI/wealth redistribution increases consumption, as more of it can be afforded by more people. The natural way of redistributing income among nations is to not protect domestic oligarchy.

There are systemic approaches to achieving clean growth that makes everyone, except those dependent on profit from slavery, happier. Evangelizing veganism and carbon footprints is fine when voluntary. Evangelism being successful on a mass scale, however unlikely, still leads to the usual coalition for fascist solutions, or accusations of it.

There are perfect effective systemic voluntary solutions (UBI, carbon taxes) to sustainability. Degrowth, will never be popular. Carbon footprint, was a shift to personal responsibility PR ploy paid for by BP. Degrowth, as a policy goal, or just loose association (like DEI) with one political party, would have a divisive benefit to oligarchism, and making reactionary oligarcho-fascism "populist".

We got here, because I was arguing with dishonest troll spouting loser US empire propaganda, btw. Climate terrorism is awesome, because China did not solve it in 2023, according to them. By coincidence, the climate terrorist supporter also advocates for degrowth.
