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.

Heat pumps were supposed to transform the world. But it’s not going as planned. | Heat pump sales, critical to the transition to clean energy, have slowed in the U.S. and stalled in Europe. (wapo.st)

HOA has banned solar and Gas heat is still way, way cheaper here. I could go heat pump, but I'd be paying 4-5x higher just to stick to my principals.

So glad my state banned the ability for HOAs to do that.

HOA has banned solar How is that legal???

It's 'ugly'. Also the rules were set in the 80s and I guess people didn't care then. And it's not like a law has been passed removing their authority to do so.

Each state is varying levels of stupid. One of the few times where the existence of the Federal government makes sense. They should ban the bans at the Federal level.

I'm in the same boat. The cost to run it would be comparable to what we pay now for heat + AC, but with a $22500-ish installation cost up front, and no chance of recouping any of that through ongoing savings. That's hard to stomach, as much as I'd like to.

How big of a house do you have?!?

[–] [email protected] 8 points 3 weeks ago (1 children)

Not unreasonably big, but my state started offering rebates on heat pumps some time ago, and the price of installation mysteriously went up by about the same amount as the rebate shortly thereafter. Quite a coincidence, that...

My state has been offering rebates for years and for a 1200 sq ft house installation and the heat pump was about $3k. Going from an old forced air furnace to that just about halved my winter electric bill!

The down sides would be the outer rooms can get a bit chilly, but for me at least it's far from a deal breaker.
