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.

The city belongs to a small handful of jurisdictions that pledged to reduce greenhouse gas emissions 80% by 2030, relative to a 1990 baseline measurement, as well as maintain complete carbon neutrality by 2030. Staff presented the most recent data on emissions from 2024 to the council, which showed a marginal decrease from the previous year but still a ways out from the 80% reduction target

The last repeat of 2030 in the above is because they're talking about cutting actual emissions by 80% by 2030, and using offsets for the remaining 20%
