A new hybrid subspecies of puffin is likely the result of climate change
- nh23423fefe 3y ago> Strikingly, the hybridization occurred after a subspecies migrated southward, not poleward toward cooler temperatures, as might have been expected, a finding that highlights the complexity of the changes underway in the Arctic ecosystem. So the line, "ecosystems will shrink as isotherms move poleward" is just wrong. Climate mitigation is just a formless cudgel.
