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.

We need to invent carbon capture!

Meanwhile: trees

Trees doesn't work either, they die and release all that carbon back into the atmosphere

The goal is to harvest them to use them in construction work. A house frame can stay as is for over a hundred years or more, enough to regrow the trees harvested twice or more. We just need to make the harvesting process less energy intensive...

Trees do work though...

  1. Buy land that is not forested
  2. Plant trees
  3. Is forest and love trees replace dead trees
  4. Wow look consumed carbon
