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 sincerely doubt Rivian has any cars in the pipeline that aren't SUV, truck, or crossover.

But yes, if someone's gonna drive a fucking excessive vehicle, it's better that it's electric than ICE, absolutely.

Their pipeline is all smaller than their current R1S and R1T at least. I'd guess 5000 lbs for R2 and 4400 for R3. I hate these bloated vehicles too but weight should creep down as battery density continues to improve along with charging infrastructure. The problem is the culture (and the infrastructure and the non-existent pedestrian safety standards).
