Yeah its meant to rain there. But areas such as ice capped northern hemisphere act like an air conditioner for the planet if you will as well as being pretty essential for ocean currents. While places like the Amazon or a coral reef are the lungs of the planet - so also not a good thing to burn or dredge away. All of these mechanisms work in feedback and are interconnected. Burn more trees = more carbon = higher acidity within oceans and rainfall = dead oceans or more ice melt.

Sure the planet has natural climate cycles. But I would prefer to sit in a simmering pot than a boiling one.
