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.

Because relentless bad news breeds cynicism, which is demoralizing and self-defeating. In this community there's already plenty of that to go round. The full story is slightly more complex.

Economic growth makes us all better,

No. Economic growth under capitalism is the problem. Capitalism requires infinite growth on a finite planet, and this is what got us here in the first place. So this is not a sustainable economic system.

Having a country with billions of people is more of a problem than economic growth. We should cull the global herd by 90% for the sake of the planet and the survival of the species. Coincidentally, this would also impact economic growth, so I guess it’s a win-win.

To be clear, the problem is a factor of total population and per-capita economic activity. So reducing either will logically mitigate the problem. (The X factor being technology.)

You seem to be advocating global genocide so your take is rightly unpopular.

But clearly population is a major part of this problem. The sheer figure for human biomass is totally unsustainable for any kind of healthy global ecosystem. Personally I find it irritating that there are so many who deny these inconvenient facts.

That’s not actually genocide. I suggest it be random.

Okay Thanos, that's enough for today. But you may be excited to know that birth rates across the globe are falling to the point that a population decline is in the works.

Thanos was right, but he was weak. Half? That only buys time.

It does make me happy the population is going down, but it will go back up again. We have too many people for the resources of our planet, and the way we use those resources. We need to give back large amounts to Mother Earth.

I dunno man, I bet the current population trajectory plus improvements in efficiency/ conservation with a lot less capitalism will likely be sufficient. 90% just seems like a lot more work than necessary.

Prior to the Industrial Revolution the population hovered around 1 billion give or take a few hundred million. Let’s go back there.

The planet could handle more with modern tech and conservation practices.

That’s never gonna happen
