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.

First, most credit should be based on recent years. You can only ask for relative progress, meaning improving year over year from recent progress instead of going from 0 to 100% renewables by tomorrow.

EU has greatest success in recent years in terms of emission reductions, but only because their energy growth has been slowing. China has much higher renewables growth from a much higher renewables base, but their emission reductions are more modest because of massive energy growth relative to massive manufacturing growth. At the same time, any growth rate at all from here is going to lead to massive emission reductions in upcomming years, just as it can continue in EU.

Trump's UN speech is desperate extortion/war cry on EU and world to end breakthrough dead ender energy extermination on the cusp of clear human victory path.
