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.

All these businesses know they are doing the wrong thing but the CEOs answer to share holders and shareholders only focus on profit. Governments are the only way to fix these big societal issues because any business who is early to make costly changes that affect profit in the short term will get killed in the market. If the government mandates changes, all businesses have to comply. No business has to stick it’s neck out to change, it’s an industry expense they all must make. Businesses hate risk without profit growth potential. The capitalist system just isn’t designed for these types of changes without a government guiding hand.
