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.

The race between climate change and the fossil fuel phaseout is growing more, well, heated. Without substantial policy intervention, the planet is on track to surpass a catastrophic temperature threshold within the next decade, the U.N. Intergovernmental Panel on Climate Change forecasts. I have to hope human ingenuity and an instinct for self-preservation will help us make our deadline.

lol @ "in time"

In time for what? Will we turn away in time to still make tons of money extracting and burning fossil fuels?

You betcha. We're right on time for that.
