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'm all for it and I'll watch as much as I can, but I'm really not sure what it aims to do? I have zero belief it'll have any effect on Trump and his goons.

I recommend:

  • Call your congressional representative and senators. Hearing from constituents, even ones they disagree with, tends to push congressmembers towards the right thing a little bit.
  • Organize locally, with people in your community. Showing that you've got people who are organized around an issue is much more powerful than individuals calling on their own; this tends to suggest that people will vote as a bloc for change, which is a big deal for elected officials.
  • Reach out to people whose lives are impacted by research. Think of for example facebook groups of people affected by a disease, or people with a vested interest in knowing about potential natural disasters. They're a natural constituency for pushing for policy change, even if they don't realize it yet.
