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 you look at most reources you will find that the richest 10% make up about half of the global resource consumption. That is not just true for energy, but also for things like food due to meat. At the same time there is a minimal base for resources and we are going to adapt to new circumstances. Especially with resource constraints not being a total cut, but a slower process, this is bound to happen.

It becomes even more striking, when you look at how resources are disributed globally. Brazil for example is in a decent state. Able to provied enough food for its population and has a good bit of renewables. Obviously poverty and crime is common today, but it is certainly a workable position. Europe as a whole might be able to just cut down and survive for a bit. Nearly 29% of primary energy of the EU come from low carbon sources and the EU is food independent, with massive overconsumption of energy and food. So cut backs and some adaption might make it work.

Poin is that it is that a 90% death rate is very likely massivly overstated. Some regions will be in trouble, but not everybody will be.
