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.

That's optimistic. People only learn from failure. Jingoists would have framed Gore as weak (like Carter) for letting 911 happen and not replying with a rampage, later to have gone on stupid wars anyway. People only remember the failures, not what was done right and managed right in the background for them.

I really don't think it was. This is a very well known point of contention clinton administration vs bush/cheney administration. They still were cold war russia focused and clinton was terrorist focused. Its like the 911 report. You read it and its very obvious all they had to do was make cockpick access external and not have direct access to the passenger area. Instead we got the patriot act and security theater. The book is there and anyone can read it but it was long and non readers just won't.
