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.

Four years ago, European officials made a plan to reduce dependence on Russian gas and ramp up renewable energy, but a new study found it only reinforced existing decarbonization trajectories and missed the opportunity to meaningfully accelerate the clean energy transition.

Most renewable energy infrastructure is made in China using fossil fuels, and shipped from there using fossil fuels. So that is negatively affected by blockage.

The fraction of fossils of world primary energy use remains effectively at some 80%, so there is no energy transition.
