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.

I don't know where we are going.

Famine, war, collapse of civilisation, rise of warlords, loss of knowledge. Everywhere. Within our lifetimes.

Just look at the first of those and the rest follow. Think about how likely it is that our civilisation will be able to grow crops in the quantity it has up until recently, even five years from now, given the increased frequency and severity of extreme climate events.

That's what I find confusing. We (global we) have already had enormous crop failures and disasters recently. https://www.agweb.com/news/crops/crop-production/farm-bureau-finds-2022-weather-disasters-amounted-21-billion-crop-losses these events can get amplified on social media and then it's disorientating to me when the effects slip away.

I think what I want is data:

https://ourworldindata.org/agricultural-production

I don't doubt it's going to get worse, but I'm struggling to understand the details of that. You're saying famine in Chicago, full on North Korean style society? War, yes I said already we already do that all the time. Not new. Warlords, not new. Loss of knowledge? Vague. I'm sorry but this is what I'm talking about. How did you reach these conclusions, if you know?

I don't follow. What is it you find confusing?

Unfortunately, due to the way time works, nobody can give you data from the future.

You're saying famine in Chicago

Yes.

full on North Korean style society?

I don't know what you mean by that.

I'm sorry but this is what I'm talking about.

Again, I'm not sure what you mean. What is what you're talking about?

How did you reach these conclusions, if you know?

Firstly, the accelerated pace of global warming compared to predictions; we've already exceeded 1.5C globally for a short duration and things are getting worse not better, fast. It looks like we're going to go well beyond 2C and we're going to get there very quickly. The greatest fears of climate scientists 10 years ago now look like optimistic pipe dreams.

Secondly, the inaction from society as a whole. The time to have acted in order avoid the issue was 60 years ago. We're now well into the situation where people are dying and billions, even trillions of dollars of damage is being done by extreme weather and yet there are people in governments who are still literally in denial about the scale of the problem or even whether the problem exists at all. And most critically, the populace is not holding those people to account. Governments are still issuing new oil and gas drilling licenses. Airports are still adding runways. Our civilisation continues to increase CO2 emissions which is the wrong direction if you want to save humanity.

As a civilisation or perhaps species, it seems that we do not have the capacity to deal with this problem. The reality of the situation seems to be beyond the grasp of most people. We don't, as a society, have the means of identifying and fixing the psychological shortfalls that inhibit most people from acknowledging the scale of the problem. It's like the problem is so big and its consequences so dire that people cannot bear to look at it with their eyes open. They would rather keep their eyes closed, even if doing so reduces the likelihood of them and their children surviving. Humanity is like a rabbit, frozen in the headlights of climate change.

I have a suspicion that many governments have already concluded behind closed doors that they cannot prevent global calamity and so are just trying to put off the inevitable downfall of their respective societies and live in comfort for as long as they can.
