....but, in theory, if we were headed towards a maunder minimum (we're not.), could canada actually get colder while india burns and sinks?

sure.

and, that would be climate change happening in different directions, in different places; what would be happening in the north would be no less of a change in the climate than what is happening in the south.

but, we should expect some kind of reprieve in the north, for at least a few years.
