In principle I suppose one could build very large walls around it to reduce heat exchange with the rest of Earth and a statite mirror (or few slowly orbiting ones) to warm it up. That would change the southern hemisphere circulation patterns somewhat, but could be arranged to not affect the overall heat balance of the rest of Earth.
This is very unlikely to happen for any number of good reasons.
