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.

Also, notably, the Pentagon (US DoD), which has been making plans for preparing or moving facilities (especially navy bases) for rising sea levels and other climate change effects for at least 2 decades.

When I learned about that it made perfect sense, because long-term projections and planning is what they do, and I realized that everyone who denied the climate change evidence was an ignorant fool. If DoD is doing prep work for it then there's more than just evidence of occurrence, there's enough practical data to do serious planning with.

That makes an excellent point to bring up with deniers. Love to see one stumble-fuck around trying to praise the military while saying they must be run by liberals.

It is a good point but I have a family member who will begrudgingly not push back too much about whether climate change is happening (though you can tell he wants to) but will argue that you can’t prove it’s man made.

You’re fighting decades of propaganda and it’s hard.
