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.

Like, the solution has become very clear and apparent.

Solar panels and batteries on all homes. Wind energy wherever possible with gridscale backup. Electric vehicles for anything with an axle-weight below 10k. Hydrogen (if we must) for everything above 10k, until we have batteries with weight to performance ratios that can support trucking with electric.

Climate change and carbon reductions are only a technical issue if you insist that every one be working all of the time to justify their existence. Appreciating that most of almost everyones work is just 'busy' work in the exercise of justifying our existence, we could easily solve this issue.

Actually, big rigs being all ev is fine for last mile / in-city delivery.

Germany's electrified highway system looks very promising for longer distance truck transport too. It's basically the same system that overhead electrified rail uses. That way the battery only needs to be able to get the truck to and from that highway, the distance covered on the highway is charging time.
