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.

They reportedly use heavier duty starters and batteries, and it this supposed to start up if the battery is getting drained. It doesn't stop automatically under certain temps and maybe above certain temps, not sure on the latter. Whether they got the engineering right depends on the design and manufacturer.

I personally see it as a dead end for gas o ly vehicles because it requires too many assumptions to work automatically in all situations. It already works for hybrids, because it can just donits thing off of battery draw, it doesn't care about vehicle speed.
