I think humans are pretty good at warming things up. So I would take a mini-ice age over global warming.

Yeah, heating is usually more efficient than cooling, because energy is usually produced with some kind of heat output. All though agriculture is a serious concern; you might starve several million people in africa.

Surprisingly this is not true. A watt of energy can only produce a watt of heat, but can remove several watts of heat from a space.

That said, we're much better setup to increase total entropy in the atmosphere than decrease it (via heat sinks eg)

Those displaced Joules are just moved somewhere nearby and are joined by the energy spent moving them.

Yes, hence my second statement and use of "space" in the first.

From a purely scientific view, yes, you can move energy easier than you can cool it. However, people in hot climates usually prefer cold air blowing, which takes more energy to chill.

Not just Africa. Probably every continent, because yields would tank and growing seasons would shrink.

It's weird that they call it "mini ice age" then follow up with - we had one in 17th century, London got temperature below 0 in winter. Not what I imagine from the name.

Humans are bad at distinguishing small but close from large but far away for abstract ideas like climate.
