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 picture would of course look very different if manufacturers had chosen to make smaller inexpensive electric sedans.

I mean you are pretty explicitly expecting people to buy a car just to go to work and groceries.

More to the point NEVs in NA and quadracycles in Europe are already available, and indeed represented the majority of the EV market about fifteen to twenty years ago.

They didn’t really find a market in the US and most of the companies that made them failed, but have remained semi-successful in Europe where their low cost and less strict licensing requirements made them popular with teenagers and seniors.

Nevertheless, it was only with 250mi plus ranges that EVs actually stated to push gas cars off the road in any number.

Generally, on the internet, it is helpful to at least lampshade when you are proposing an idea that is very far off and/or disconnected from both the context of the conversation and the way you think the world actually does work, especially when in a community that regularly discusses legislative and technical details and changes of the clean energy transition.

When the conversation started from a news story about how a ok method of reducing emissions in the US is achieving more than technically better method because it’s seen slower adoption, passerby’s are going to assume given that context that you are talking about changes to be made in the few short years and decades we have to stop the destruction of civilization as we know it into account.

Aaand that's several more paragraphs on condescension.

So what I'm getting is this: your problem is that I didn't write my comment in the form of a watertight essay, while discarding any mention of anything that is unlikely to occur in the immediate future?

I don’t have a problem, I’m just explaining why when you start talking about the far future in reply to a problem in the here and now without any mention that’s what your doing you shouldn’t be surprised someone might think you were talking about a reasonable solution to that problem and explain some of the barriers to that solution.

Still it’s getting late, and we are off topic from off topic and dominating the comments on something completely unrelated to the conversation, so we should probably leave things here.

I apologize if I was to snarky in response to the rhetorical questions, and I do hope you have a lovely day/night.
