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.

The new standards require American automakers to increase fuel economy so that, across their product lines, their passenger vehicles would average 65 miles per gallon by 2031, up from 48.7 miles today. The average mileage for light trucks, including pickup trucks and sport utility vehicles, would have to reach 45 miles per gallon, up from 35.1 miles per gallon. Selling electric vehicles and hybrids would help bring up the average mileage per gallon across their product lines.

In many different areas. This is the per year registration fees in Ohio. These fees are meant to compensate for road damage, which is calculated based on vehicle weight. Except Ohio just said “well batteries are heavy, charge them.”

A lifted diesel super duty getting 12mpg will run you 0 dollars and 0 cents whereas even a plug in hybrid runs 150$ per year. Completely independent from the weight of the vehicle.

Biden can do what he wants but conservative states will constantly delay the transition to EVs, slowing adoption, infrastructure and the publics willingness at every opportunity.
