That’s a great cartoon.
Climate change seems to be behind the shockingly warm temps across much of the eastern Arctic all winter and is likely responsible for the snow has fallen across much of the southern US. Much of Arctic ice sea melted last summer, allowing the Arctic ocean to warm up which then took longer to freeze i.e. late Dec/ Jan. And that changed the wind circulation patterns bringing polar air far south.

And finally here’s a short video by Peter Sinclair of Climate Denial Crock of the Week explaining this: Global Warming. Winter Weirding.
