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.

Wherever you look, you'll hear headlines claiming we've passed 1.5 degrees of global warming. And while 2024 saw record breaking climate change, this might n...

No, it's not "game over". It will never be game over. Humans do not have the ability to destroy the planet.

What we do have is the ability of making it hard for lots of regions to sustain complex biodiversity and human activity. The more and the faster the average global temperature increases, the more people will be displaced and biodiversity lost.

Nature will always bounce back because nature operates in geological scale. But human civilization will suffer a lot. Vast areas will be progressively destroyed by droughts, floods, fires and encroaching sea, which will continue increasing migration to safer places, causing more and more unrest and war.

So, yeah. Never game over, just progressively crappier levels.

I think they mean game over for us. And yes, it’s game over for humanity on a global scale. Good, we suck.

It's not though. You an I would probably die if your civilization collapses, but millions of people live away from civilization. Humans will definitely survive this, but many modern societies won't.

Easy as hell to be a doomer. That's why I admire scifi authors that dare to guess the form a better world may take. And yes I'd appreciate any "hopeful scifi" media recommendations.
