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.

We can't reverse it, but we can limit how much more warming we get.

Wait is it time to freak out, or are we still being hopeful?

[–] classic@fedia.io 31 points 7 months ago

Yes it's time to freak out...

...about the AWESOME savings at your local Dollar Tree! Where plastic trinkets are 2 for 1 - that's right, 2 for 1 - all this week! The more plastic trinkets you buy the more you save!! Now THAT is a recipe for hope!!!

The time to freak out was probably before you or I were even born.

[–] ProdigalFrog@slrpnk.net 8 points 7 months ago

We should be freaking out, but as Silence7 says in the text body, we can still limit how much hotter things will get, but we need to move quickly.

Nah, we're getting ready to get fucked.
Whatever disagreement still exists is what kind of lube to use before we assume the position.

[–] ax_xa@lemmy.world 7 points 7 months ago (1 children)

There will be no lube.

It will be sand with shard of glass in it and every now and then some ghost pepper powder
