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.

And so installers were harder to come by, which means fewer people were told about it. Pretty easy to understand why it took a while to catch on.

Mine is air to water, so all you really need is someone who can plonk it there and then plumbers to do their stuff.

Vast majority of the work for mine was replacing the entire central heating system, but that would have been a good idea even if I wanted a gas boiler because of how old and shit it was.

Now my cat can sleep on top of the large double radiators around the house. Tbh that has to be one of the best features of it, flow temperatures low enough that a cat can comfortably sleep on it.

When i was trying to get a heat pump, i had to listen to a family friend hvac guy yell at me for 10 minutes cus he hates those damn things.

Ohhh I heard some of those! Got told that the heat pump alone would cost more than twice as much as I actually paid for a heat pump, all new radiators and replacing all the old pipework.

These cheap mini splits can be installed diy.

You vastly overestimate the capabilities of the average modern human being

That's incredibly short-sighted since they still paid for themselves.

Not for apartment dwellers.

Cool beans. Try being poor.
