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 never changed my pads in 65k miles so that's not true sorry.

They are on average slightly heavier but we're talking 100-200kg. That's nothing, 10-15%, definitely not "substantially". Less if you add fuel to the ICE.

There's not any extra pollution. There's an investment cost and then tyre wear. Which you get from an ICE. Along with, you know, all the pollution from the combustion engine. Which is at most 24% efficient (more likely middle teens) and only continues to pollute rather than electric vehicles which don't.

Electric cars may not be the ultimate solution but they're a damn sight better than the status quo so let's stop this kind on hysterical posting eh?
