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.

What does life expectancy have anything to do with energy consumption? I was talking about overpopulation. More people equals more energy consumption. That's just science.

We have a much better understanding of disease these days, so we can indeed keep our longer life expectancy, without acting like we somehow need even more people on the planet.

Once upon a time, the internal combustion engine didn't even exist. How did people get around? Either on foot or by horse. Or bicycle, if you wanna get fancy, without burning any more fuel than the calories you consume.

Once upon a time human generated electricity didn't exist. I mean sure it's nice and all, but people lived without it for hundreds of thousands of years.

And once upon a time gunpowder and shit didn't exist. Welp, that and other cats are out of the bag now ain't they?

I dunno, it just seems to me that overpopulation and the human addiction to energy is like 3/4 of the overall problem.

People living to old age means more people are alive at the same time, that's just math.

And people living on ventilators and suffering dementia or paralysis or other debilitating ailments is hardly anything worth calling any sort of quality of life. I'm 42 right now, and at the rate things are going, both with my own health plus the rate people are ruining the planet, I kinda hope I croak by age 60 or so.

The human body isn't meant to last forever, and if they ever think they gotta put me on a machine for any length of time, I'm gonna be like fuck that, time to check out.
