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.

Why Can’t the U.S. Build 5-Minute E.V. Chargers? Chinese automakers have rolled out chargers that can mostly recharge a car’s battery in about five minutes. Yet U.S. technology lags far behind. (www.nytimes.com)

Where on earth did you get 50 kW from? My car isn't very efficient and it's more like 18 kW on the freeway.

With an average consumption of 50 kW a first gen Nissan Leaf would last like 20 minutes. They were short range, but not that short.

Haha, I knew I was making a mistake when I was writing that figure.

ICE efficiency is around 22% so 50 kW × 0.22 = 11 kW constant.

Your figure of 18 kW is more pragmatic/empirical, so I defer to your measurement :)
