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.

Love to see it. Unfortunately we're still early in the phaseout of HFCs via Kigali, and the chemical companies are doing their best to inject HFOs (and resulting PFAS) as far and wide as possible. We all need to shift to natural refrigerants ASAP. If you're buying a refrigerator, make sure it's r600a, a heat pump, r290 or r744, etc. Say no to HFOs (and HFCs).

Hey there your friendly neighborhood ref tech. R600a and R290 are straight up bad ideas ( more than a wee bit flammable (isobutan / Propane) ) and although r744 is good ( CO2 ) it's pressure are nuts. ( the whole system needs to be made of steel/iron) and would not work well with most common split systems. So ya nice idea I am not sure what's next but these are not the answers in private residents.

There are some cars driving around with r744. In a crash the front explodes like a bomb, but it doesnt get on fire
