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.

Extreme heat should inspire urgency, not doom | On climate change, both denialism and fatalism are mere postures, not serious points of view. (wapo.st)

I think knowing that nothing is going to happen is a serious point of view.

A lot is happening though; it looks like Chinese emisions are starting to drop

We've likely already shifted from a 4°C world by 2100 to a 3°C by 2100. That's not enough but it's also a lot more than nothing.

All these governments and companies had enough data for literal decades to know this was going to happen and they all decided to do nothing but increase production...
