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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The power company here keeps pushing heat pumps, but it frequently gets down below freezing and often below 0F during the winter, and my understanding is that heat pumps just can't efficiently keep up with that, if at all, so supplementary heat is still needed. Is that no longer the case? "Every American" includes a lot of people in that same situation.
The article cites that it would save the average American $550 a year on utilities, so when you consider that it costs ~$15-30k to have a heat pump installed, we're looking at a 27-55 year break-even point.
It makes sense for new construction but they seem to be advocating for retrofitting existing homes, and I just don't see how they're making the claim that it's economically viable. It'd take some mega subsidies to make that possible for most people, I think.
In addition to Thejevans points, your cost estimate is very high. That cost would be in line for a geothermal heat pump, which is far more efficient. Air to air heat pumps can be installed for more like $3-10k in most residential homes. And on the higher end that is a big house that is probably saving more than $550 a year.
Can you show me where you're getting those figures? I was basing my estimate on a quick google search of prices, and the estimate provided for air-source heat pumps here. (MassSave is an organization that promotes energy efficient and climate friendly appliance solutions in Massachusetts), which seems to suggest $22,000 is an average cost, which is in line with the other estimates I was finding. ($10-$20k to buy the unit and $15-$30k including installation.)
Edit: To be clear, I'm not trying to be contrary or argumentative; I've been looking into heat pumps as a possible option for us for years and if they've become justifiable from a cost perspective, I'd love to get those details.
I looked up prices in Massachusetts, they are higher than the national average. Looks like 2 main factors:
1 A higher than usual percentage of mini splits vs central air. These will be more efficient and have a lot of comfort benefits, but are considerably pricier then retrofitting a central air system. So if you are retro fitting CA, you could come in under average.
2 MAs impressive $10k+ incentive system for whole home heat pump systems has resulted in HVAC companies raising prices, because of course it has. This is why we can't have nice things.
