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.

People were using other fuels before they start using fossil fuels. Like wood. It is double whammy - more CO2 (less efficient burning) and no CO2 recapturing by those burned trees.

Oh no! Not the 680M or fewer people burning one of the less dense forms of carbon for home heating and cooking food! This is very noteworthy alongside industrial and motor usage of hydrocarbons that have to be extracted from under the ground and water for the population of now over 8 Billion!

Much more efficient per person though. Or per Joule of energy.
