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.

It's more like saying "the Heisenberg exploded, hydrogen blimps won't work"

The Heisenberg exploded because of ruptured bladders and structural cables snapping, among other things. Hydrogen blimps could work - technologically they're still very feasible

But they're too risky to half ass, and their biggest proponents have shown themselves to be incompetent in the face of the engineering challenges involved

It's not just shit technology - it's about execution. If no one can demonstrate good execution, we have nothing. Better ideas have been killed for less... This whole concept is riddled with unsolved problems - it's not feasible with the players on the board

This is too important to fuck around.

Heisenberg exploded? The scientist or the one from Breaking Bad?
