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.

Maybe EVs are not a comprehensive climate solution??

The proliferation of a new technology typically doesn't start from poor people.

It starts from fanatics first. I built my first EV. It was crap, I cut it apart and sold the metal (environmental footprint: awful). Then I built my second EV. It drove around 10 000 km, but had to be retired due to metal fatigue (enviromental footprint: neutral at best, lesson learned: big).

I bought my third EV on a crashed vehicle auction. New front axle, stretching the frame back to correct dimensions... I drive it every day, but it's a crap car that I'd not recommend to my worst enemy. :) Environmental footprint: positive, I can produce fuel for myself from April to October. But if the same vehicle would be used by someone who doesn't produce (or buy) renewable power, the footprint would be less positive.

Anticipating the demise of my factory-made electric microcar, I am however building another EV. Again the footprint is negative, but I need information about how to easily manufacture one, and obtaining information has a cost in resources. :(

Meanwhile, of course, truly rich folks buy fancy and electronics-laden self-driving EVs which some then proceed to crash or mishandle due to lack of clue. People are like that and it will stick out in statistics.

IMHO: if they hadn't bought an EV, they'd have bought another kind of status symbol and would have used it even more wastefully. What matters more is what the average person can and will do. And how do we influence the auto makers to produce less resource-intensive vehicles?
