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.

Evidence shows how major fossil fuel companies use climate disinformation and greenwashing to delay climate action and evade accountability.

The report: Decades of Deceit: The Case Against Major Fossil Fuel Companies for Climate Fraud and Damages

From the report:

Research has determined that just 122 companies are responsible for more than 94 percent of all industrial carbon dioxide (CO~2~) emissions since 1959 and 75 percent of all industrial CO~2~ emissions since 1981. In these time frames, fossil fuel companies already had clear scientific evidence that their products were contributing to climate change.
