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.

Well, yeah. They've stopped building at scale internally. Now they are trying to export as much capacity as possible.

Been waiting for this for 20 years ... (was shocked how much those emissions rose post 2004)
What's important now, is that India and Africa don't follow the same type of concrete path

'China’s in-use cement stock – a measure of all the material in buildings, roads and structures – was about the same in 2013 as the roughly 15 tonnes per person in the US'

Where can i get data for each country's in-use cement stock ? Seems like useful metric (I think incorp in my model)

Good data, perspective and not pandering. Thanks for the link.
