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 went to a climate protest in Canada last week and it was way to tame to actually get anything accomplished.

The main part of the protest was walking down a main artery. For protesters, there is incentive to walk slowly and spread out to make the walk longer and disrupt status-quo longer, but the organizers clearly only had permission to march for a specific duration so they were in the back hurrying people forward so we'd stay within our allotted time window. Maybe 30 minutes. Once a year. It was pointless.

Add to that that 90% of the people there were exactly the people you'd expect to be there and it just felt like a waste of time.

It absolutely was a waste of time, nobody noticed or gave a shit.
