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.

Sorry to tell you this, but if we suddenly woke up tomorrow and made all the possible drastic changes in a single day, it would take well over a decade for the effects to even start setting in.

The chaos we are living today could only have been prevented by starting many years in the past. So is the reality of very long geological cycles and feedback loops.

A decade from tomorrow is better than a decade from a decade from now

what do you mean?

As more extreme policies become required, fascists gain power because of the increasing disruption to the way of life that the average person in the region is accustomed to.

i think the people who were gonna be fascists anyway are already drunk on that mentality, regardless of what we tell them at this point.

i think theres already a foundation being built in the world's stage to fight back.

i guess we will have to see on that one.

Drastic measures can mean prevention, mitigation, or retribution. It's too late for prevention, so right now mitigation is the next best thing.

[–] kadu@lemmy.world 1 points 9 months ago

Mitigation follows the exact same "extremely delayed effects" logic I explained.
