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.

You say this as if things like variable speed compressors, multiple compressor stages, and designs other than the generic mostly empty box with an open vertical fan on top don't exist for air conditioners as well.

Your previous air conditioner was designed for its intended purpose. Based on your description it almost certainly didn't have the hardware to function as a heat pump, so being inoperable during a snowy winter wasn't an issue, given it's designed use. On the other end, it was the house I'm in has had three air conditioning units over its lifetime. None of them were an open vertical design like that, and I'm in AZ where snow is irrelevant.

You're talking about equipment designed for the intended use case of cold weather that takes environmental aspects like snow accumulation into account for its design instead of ignoring it, and acting like that is some sort of new technology. It's just better designed and not just the cheapest shit they can get people to buy. Whoever bought an exposed air conditioning unit like that in an area with regular snow was an idiot that clearly did zero research.
