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.

The higher the number, the greater the government’s justification for compelling polluters to reduce the emissions that are dangerously heating the planet. During the Obama administration, White House economists calculated the social cost of carbon at $42 a ton. The Trump administration lowered it to less than $5 a ton. Under President Biden, the cost was returned to Obama levels, adjusted for inflation and set at $51.

The new estimate of the social cost of carbon, making its debut in a legally binding federal regulation, is almost four times that amount: $190 a ton.

The Chevy Bolt is cheap and feels it. Read my other comment on it; I have driven one more than a few times, ridden in one even more often, and it’s absurdly bad compared to even a base level Mazda3 in interior quality. It honestly feels cheaper than my my first car, an early 90’s Toyota Tercel, let alone compared to a modern import. If the Bolt is the future of EVs, we’re doomed, because it’s not fun to drive and every moment in it is a reminder that it’s cheap for a reason. It may be better than the Prius C due to being an EV, but that’s not exactly a high bar to clear, and I’m pretty sure it will lose where it counts, customer satisfaction. I can’t imagine someone with the money to buy something better puts the money down for a Bolt and is happy with their decision after six or 12 months, let alone the decade plus that we all should be keeping our vehicles to defray the environmental cost of their construction.

That leaves people with limited financial options, the people forced to buy either a used ICE vehicle or the cheapest EV when their old car dies; you’ll probably recognize them as the working poor (and their ranks are growing thanks to runaway capitalism). If the solution is to force them into terrible vehicles, perfect; the Bolt should serve as a wonderful reminder that profits are valued above them at every step.

I agree that it is cheap. It's entirely possible for manufactures to do a lot better at that price point, but it's less profitable.

Right, and since profits are king, the affordable electric cars will stay terrible because an ICE is $1k or so to manufacture while an electric power train including battery is at least five times that in cost. When you look at a $27k car, tax incentives excluded (especially because some people will be unable to use them), the electric car has to be cheapened, every corner cut, or the profits just won’t be there.

Again, it’s dollar for dollar, when you sit in a $20k Mazda versus a Chevy Bolt that will cost the same if the full $7k tax incentive is realized, the quality difference is tangible. Until that’s addressed, there won’t be people wanting to buy that car.

They've been selling out the entire Bolt manufacturing capacity. So clearly people do want it

Do they, or is there a lack of an alternative in that niche? Again, I can only speak from my personal experience driving and riding in one; I’d choose pretty much anything else with four wheels.

There have been a few other low-cost models. Also all selling out.

They'll make them fancier if that stops happening
