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.

  • When we adopt the role of protagonist, name a villain with evil motives, and then collectively strive towards a common goal, we can cure diseases and win world wars. Yet the climate movement hasn’t created a narrative like this to maximize our cooperative power, largely because the fossil fuel industry beat us to it.
  • Our second task is to dramatically increase the number of voters who demand climate leadership.
  • Third, the climate movement doesn’t just need to change how we do politics, we must also change when we do politics. Climate policies are made at every level of government, and mayors want to win elections just like presidents do, which means they too are subject to the whims of their voters.
