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.

one of the big American car mfg like GM was bragging that they developed a mushroom-based automotive tire that used no petroleum and was non-toxic/organic but then never produced any for sale and i cant find any press releases now for it.

I never heard of a mushroom or fungus tire but Goodyear has been working on a tire made from old recycled tires and moss. I think most manufacturers have recycled and or sustainable products but they still cost more than the base level tire most people end up buying. I have heard some manufacturers are looking at using organic rubber from tree and dandelion farms.
