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:

You can also do things like mini splits in many areas instead of expensive, bulky, insulation-piercing, unreliable ducts.
I wonder if you could do that instead of central air. I've lived in houses where certain rooms don't get AC or heat, annoyingly always mine. having one per floor, internal insulation, separate smart thermometers etc. could provide both better heating and cooling and eek out energy savings.
You can't always retrofit just by installing a mini split head in each room (with each external unit providing 1-3 heads), as some older houses don't have insulated pipes etc and cold can do other damage.
As part of a bigger remodel or a new build, absolutely.
I was thinking of new builds, retrofitting old buildings has it's limitations, not to mention how some old homes in urban areas are better off torn down and replaced by denser housing
Oh. Absolutely.
You can also go even further. Heating the people directly through various methods (well placed skylights/windows, infrared panels, pointing the head unit at the people) can reduce the temperature you need to keep the building at.
