The ‘substantially heavier’ is doing a lot of work there, given the change is only about 5 to 10% on average and typically EV’s are still not the heaviest vehicles in their same class. Compared to the car obesity epidemic in North America, the drivetrain is irrelevant. A European EV for instance is nearly always going to far, far lighter than a modern US gas car.

Also, becuse if the road degradation is exponentially tied to tire wheight it is almost always a function of trucks, busses, and freeze thaw cycles, cars tend to be to light to cause significant share of the damage.

Break dust is an odd thing to bring up, seeing as one of the other common gripes with EVs is that they use their breaks so extremely rarely that they corrode and might be ineffective in an emergency.

Tire dust is an factor, but again one that’s more impacted by the increase in North America’s car size than drivetrain and which is reduced by getting cars back to sane sizes and out of dense areas like cities, not pretending that a 80 to 90% reduction in one of the largest causes of climate change is somehow the same.

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.
