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.

Following up on an paper posted earlier this week on disproportionate carbon emissions based on income. This article, by one of the paper's authors, proposes the possibility of imposing carbon tax on investment income as a more equitable means of influencing emissions.

Instead of putting the responsibility for cutting emissions on consumers, maybe policies should more directly tie that responsibility to corporate executives, board members, and investors who have the most knowledge and power over their industries. Based on our analysis of the consumption and income benefits produced by greenhouse gas emissions, I believe a shareholder-based carbon tax is worth exploring.
