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.

The damage we are creating will take thousands or millions of years to undo .... so the trajectory of problems is bad right now, will get worse in the next few decades and stay that way for a few centuries. That is if we don't figure out ways to make things even more worse.

And if we do get to the point of nuclear war and the inevitable nuclear holocaust after, it will take us a century to survive that, then centuries more to recover from the damage it will cause.

I do have hope that as imaginative and creative beings that we are, we may figure out ways to survive through all that.

However, I am also realistic and know how ignorant and depraved we can become in the face of disaster and our own mortality.

We've survived natural disasters in the past that were no fault of our own.

We don't know if we can survive disasters of our own making.

I don’t really like the rhetoric of “we” are doing this. The rich, the warmongers, the imperialists, the capitalists are the ones doing it to us and the world.

No raindrop feels responsible for the flood.

Terrible metaphor for this when the vast majority of this “flood” is being created by a small minority of people.

A billion people isn't a small minority. You and me are part of it.

"We" is a relative term when I use it here ... I don't mean specifically you ... or me ... I mean the majority of people everywhere in the world who actively don't do anything as a collective to stop all this insanity and just go about perpetuating the system that is slowly destroying all of us.
