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.

Perhaps the tax credit should be down payment assistance of the same value for those who purchase the EV if they have a household income below 150k. Maybe limit it to vehicles below a certain total cost as well.

Up front cost is a bigger road block than taxes.

Aren't your just describing the current credit? There's a mechanism for the dealer to provide the incentive at the time of purchase vs during tax filing the following year. There's also an income limit for eligibility.

That being said, the whole point is to move battery supply chains to the US, not to actually make cheap cars for folks.
