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.

Peaceful marches are effective for both independents and Democrats, while civil disobedience has a positive effect among Democrats. These effects are isolated to those who are most certain of anthropogenic climate change. No effect is observed among Republicans. Despite evidence from other studies suggesting the possibility, no “backfire” effects are observed for any group or protest type.

Interesting review, many references. Well-targeted protests can help to keep policymakers motivated, especially prior to critical moments like decisions before COPs (during the last days, it's too late). But what about the effectiveness for the protestors themselves? - directing a lot of energy to such actions might distract youth from focus on developing an 'expert' career to help climate more substantially (am thinking from own past experience...).

I don't think I've seen a longitudinal study like that, but what I've seen in practice is that teenagers who start off leading local protests end up becoming activists who engage with municipal and provincial/state government on an ongoing basis.
