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.

phev should not be allowed. they're not zero emission. Fuck Toyota for knowingly championing hybrid tech which extended petrol cars for decades.

Disclaimer: I don't think PHEVs are zero-emission. And I don't know why Canada thinks they are. With that said, let's carry on...

Since hybrid cars have less fuel consumption and the range of those vehicles don't suffer as much in colder climates, I do think it's a nice transitional technology between ordinary ICEs and full battery EVs.

Once we reach the point where charging stations especially fast charging stations are commonplace (it still isn't the case here sadly) though, it can go straight to the dustbin of history.
