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.

New fuel-economy standards, which President Trump said he finalized Saturday, would kill a federal effort to speed the transition to electric vehicles.

Electricification is the one thing that could make the price of gas irrelevant for Americans

Are you registering miles per year on roads as well?

Why would someone who drives 10 miles a day past the same massive registration cost as someone who drives 100 or 500 miles per day?

That's why it's tied to gas atm. The higher usage the more you pay.

Sorry, I missed the point where registration includes odometer readings. Sure, it's possible that someone could be driving 10k miles off-road and 100 miles on-road, thereby paying for more than they're using, but it seems quite niche and less complicated a trade-off (and much less tied to fossil fuels) than gas tax.

You said it should be tied to registration. But it's tied to gas because that reflects miles/usage and wear better

Did you read anything I wrote about electrification? The moment you add a battery it stops reflecting usage.

How will registration only be fair to those who don't drive much and still make those who drive constantly/ for work pay more?
