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.

Yes.

Those towns can pull themselves up by their bootstraps. Not your mama.

When amoc or Thwaites collapses it isn’t like we are going to have a choice. (The choice has already been made by not radically reducing greenhouse gas emissions)

Yes, and thus shall begin the mass migrations of homeless, hungry and desperate people with nothing to lose.

Unsurprising that this is such a trope of near-future science fiction.

It began years ago, haven't you heard of the migrants caravans from south/middle americas?

[–] Sir_Kevin@lemmy.dbzer0.com 1 points 2 months ago

That's nothing compared to the population of all the coastal cities.

[–] shasta@lemm.ee 4 points 2 months ago

That's not an opinion, that's a question

[–] Granite@midwest.social 3 points 2 months ago

That won’t happen though because global warming is a myth, and the earth is 6K years old and static.

Wait, why is my house floating away? Why didn’t anyone warn us?!

Please ocean, stop taking our towns /s
