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.

Systems can be broken and incentivise poor behaviour while individual actions also make a difference.

Besides, where will your political change come from? people who wont even change their diet? Just like how all those environmental protections were brought into being by people who criticised the people chaining themselves to trees for thinking individual actions mattered?

The meat industry is terrified of vegans, they spend millions rewriting laws and producing propaganda to limit us. maybe they have reasons why.

One place individual action worked was when people started making a thing of divesting from coal power plants. It worked because the pension funds followed the popular lead. With investors fleeing it is hard for coal power plants to maintain themselves, jars to get loans. It shortened many power plants' lives significantly

Where it hasn't worked: recycling
