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.

This sounds like consumerism with extra steps to me, since emissions are mostly coming from industry, not individuals.

A lot of carbon has to be emitted for the manufacturing and distribution of goods and a lot of the time it exceeds their lifetime energy consumption (and its equivalent carbon emission).

Best case scenario would be making goods more modular and reliable, so it doesn't need replacement as soon, and making it so older ones can be updated or at least mantained for longer.

e: I'm not even considering material cost and extraction.

Which is why its so brilliant. People are being forced to be consumers with a consciousness(EV). So if they can take advantage of it well more money.
