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.

All good points you are making here. One thing I would slightly disagree with is the fact that in Africa they are not offsetting emissions. A lot of the small African communities still consume energy. Mostly, it comes from running diesel or gas-powered generators, which are super inefficient and polluting.

Also, these projects can grow much larger and actually create a surplus of energy, which can then be sold to other parts of Africa and beyond, generating economic and environmental benefits.

The issue is that there is no good way of transporting energy out of Africa.

But these mini grids is a good starting off point for the locals for sure
