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.

I heard that Belgium has mandated that all new house builds must be passive homes going forward. (very cool) Can anyone confirm or deny that? Have any other regions made that forward-thinking policy?

I spoke to a real estate agent in the US who didn’t even know what a passive house was, and after I explained it he was sure that no such house existed in his whole state. I was blown away by the gross oversight.

In another US region, someone who needed a new roof said they did an exhaustive search for a roofer who could install a vegetated roof. Not a single roofer in their city or neighboring city could do that. WTF.. how are people so not on the ball at this stage?

Wow. That's just sad.
