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:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The climate change we caused is here for at least 50,000 years – and probably far longer (theconversation.com)

In February 2000, Paul Crutzen rose to speak at the International Geosphere-Biosphere Programme in Mexico. And when he spoke, people took notice. He was then one of the world’s most cited scientists, a Nobel laureate working on huge-scale problems – the ozone hole, the effects of a nuclear winter.

So little wonder that a word he improvised took hold and spread widely: this was the Anthropocene, a proposed new geological epoch, representing an Earth transformed by the effects of industrialised humanity.

The idea of an entirely new and human-created geological epoch is a sobering scenario as context for the current UN climate summit, COP28. The impact of decisions made at these and other similar conferences will be felt not just beyond our own lives and those of our children, but perhaps beyond the life of human society as we know it.

It's here for 50,000 years if we do nothing, but we're likely going to do something. 200 years. Generations one and two will set up the carbon free energy infrastructure, generations three and four will manage the return to acceptable CO2 levels and environmental restoration.

Edit: y'all need to lay off the defeatism. It's really pathetic to read.

Are these "generations" in the room with us right now?

Maybe if we get cheap automated lunar manufacturing we could set up some solar shades?

That’s all i’ve got, no one is going to put massive effort into restoring a diffrent climate for the hell of it. By that point they’ve already adapted to the new normal. I mean you might see some efforts over time in a effort to cut forest fires and hurricanes, but given that emissions are still accelerating over fifty years after the UN found we need to get rid of them entirely i doubt there’s going to be much effort to undo that.

I think solar occlusion is the way to go; you could harvest solar power 24/7 and beam it back via microwave; you could directly occlude the amount of sunlight impacting the earth, enabling fine and localized changes, and it wouldn't require pumping unknowns into the atmosphere and hoping there isn't some kind of whiplash effect down the road.

it's just expensive as fuck due to the amount of material; a lunar manufacturing operation is a must.

That's magnitudes more expensive than stopping fossils right now. Not to mention the impact on ecosystems worldwide.
