Climate - truthful information about climate, related activism and politics.

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.

It's very on brand for California to outright ban something the poors use in the name of saving the climate. All while looking the other way at big business like OpenAi

If they really wanted to reduce petroleum using cars they could remove or reduce minimum parking, zoning laws, ban strodes in urban environments, require protected bike lanes ect.

Walkable cities and affordable public transportation is the real answer, but the absurdly rich and authoritarian neolib CA prefers lip service, green washing, and gentrification.

EVs are already close to price parity (and there are some screaming deals, new and used) and battery prices continue to plummet. Gas cars will be on the roads in CA until at least 2050. The poors will drive EVs because they will be cheaper than gas cars by then (probably long before then). Yes we need walkable communities and trains and bikes but this ban is not the big scam you think it is. Keeping gas cars doesn't magically fix the actual issues with the egregious use of personal vehicles. We need fewer cars, but the cars we do have need to be electric.

The repairability of EVs is shit. Tesla doesn't sell off the shelf parts for example. There is no Toyota Corolla of EVs or anyone going in that direction, as far as I can see, especially for the west.

There would need to be a battery tech breakthrough, right to repair laws, standardization ect. Lithium batteries are too expensive and they are not getting cheaper.

There's barely even a Toyota Corolla of ICE anymore. Everything is moving against right to repair and getting more techy. The Bolt is pretty close and is coming back, and there will be more cheaper cars. I don't care about Tesla, they aren't the whole market and they are awful for many reasons. And batteries absolutely are getting cheaper:

Banning the (unfortunately dominant) mode of transportation without having the viable alternative ready is so fucking naive it hurts. Where is HSR? Where are the needed effective commuter rail projects?

The viable alternative is electric vehicles, and they are already here. I hate cars and want rail/bikes/density too but nobody is naively banning cars here.
