How about we just make a giant heatsink that reaches into space instead. Then we can cool the whole planet. Coming up with crazy ideas is cheap, but the logistics are obviously impractical.

Look into radiative cooling. Basically this, but more practical. Several companies working on it: https://www.skycoolsystems.com/

I don't quite believe this.

Is it really better than just using solar panels to run a heat pump?

This looks like it depends on the outside air to cool the coolant. "Radiative" can mean that too, not just IR radiation.

We had one. It was that sulphur used in shipping fuel.
