The little grasshopper who couldn't.
Here's a handy hint, Homo Sapiens :
If you're a warm weather animal with a brain the size of a chickpea, don't migrate to northern climates and genocide the natives. It could end very badly for you. This was true 40,000 years ago and it is true today. If you are migrating north and you're not endemic to this region you might want to get back on that boat and go the hell back to where you came from. It's serious business up here and confused 'boons should not be swayed by a small break in the normal weather cycle. Neanderthals make it look easy and it is - for us. For you manboons, could be a bit of an M. Night Shymalayan style mindbending twist coming your way shortly.
You know all those sacrifices you engage in hoping you can change the weather, like promising not to burn coal or taxing each other for "carbon" sins? IT ISN'T WORKING. Maybe it is time you packed up and went back home, wherever that is for you. Since the planet is normally cold as a rule, it is possible that Planet Earth itself may just not be right for you.
