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.

It's ironic when you think about human history .... at one point in human development, there was a population bottleneck where there were only a few thousand individuals that we are all descended from. It basically means that we owe our present world to the survival of a few thousand people.

Now it seems our species will die out because of the greed of a small percentage of our population.

We came into being because of a few .... and we will die out because of a few.

It'll create a new bottleneck for sure, but I expect there to be a few communities built up by the richest of the rich to survive with as much comfortable as possible. A large number of the survivors will be their serfs, essential staff to maintain their comfort in exchange for a chance to survive.
