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.

Also only 51% of Ethipians have access to electricity. That is access for at least four hours a day and enough to charge a phone, have some light and other light tasks. Charging an EV is another league entirly.

So this might backfire badly. At the same time it makes oil infrastructure obsolete and China is selling extremely cheap EVs these days. The BYD Seagull at $11,000 is rather competitive for a new car and something like a Guang Hong Mini for $4500 is also available. Obviously that is not used cars territory, but we are going to see second hand cars of these cars as well and they will be even cheaper.
