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.

Electric cars are not THE solution.

A tire that lasts a lifetime would shed less particles than ~~one that needs replacing every so many miles~~ all the tires used in the same timeframe, would it not?

The reason tires need replacing is because they're relatively thin. Airless tires aren't wear-less tires.

Not to mention that airless tires make for a horrible ride.

Actually earlier prototypes were wear-less, from both companies that were developing them.

As for the horrible ride, from what I've seen, that's not a problem. But even if it was perhaps that should be solved by other aspects of the car.

They're not prototypes, they exist and they're called tweels. They're only really useful for low-speed industrial equipment where ride quality is a low priority.
