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.

When it comes to global thresholds .... if you think you are close to the threshold ... you're probably past the point of no return and you're in danger.

I wish I had been old enough during the time we could've still made changes to make a difference. I try to do my best but sometimes I can't help but feel that the time to make serious changes and avoid catastrophe has passed. Good luck in what comes ahead, everyone.

There is coal, oil, and gas in the ground. There are forests yet standing. We're too late for no change — but not too late to make a very big difference in the outcome.

Even in the best case scenario of we stop doing anything at all that harms the planet this second, we will still be in for a hell of a time within like 20 years. Most people aren't willing to change their lives to this degree, so we will keep going down this path until its inevitable conclusion, the end of civilization as we know it. Anything less is a copium.

Success is far from guaranteed. But doom is in no way inevitable. I'll be fighting for every tenth of a degeee

I mean, at the rate we're heading for the cliff, seems like it will be a fight against everyone else on earth. This video I think summarizes it well

Why? When you cared back then the frustration must have been at least the same it is now. The hope might have been bigger, but at the same time, you would have been part of a very small minority. And I think it would have been hard to endure that almost nobody you know thinks similarly. You might have been the only doomer they know. And how fast we manage to screw up our planet, you would have likely gotten old enough to come to the same conclusion you came to now: we won't make it.

You're right. I should have been a better agent of change as a sperm.

Do what you can, anyway.

Friendly reminder: If you aren't fighting conservatism, you aren't fighting climate change.

People underestimate how much oxygen is generated by the sea until we start suffocating.

Seven or nine?
