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.

Fear often sits behind anxiety, and there’s been growing attention to climate anxiety. We don’t see that climate anxiety is really widespread among populations, but it is higher among younger people. Often it motivates action. What we found was that there is a positive relationship between climate anxiety and taking action to tackle climate change. Fear can be a motivator in the same way that we were just saying about anger.

This could be interesting to be studied more. All too often I hear "we need to stay optimistic to act" and "doomerism leads to inaction" without anything to back that up.

Decades of optimism about climate change have lead to hardly any action.

Personally I believe the average person needs to worry much more than they do now. While more people know about human made climate change now, most of them do so only superficially and very optimistically.
