In the past, around 53 to 38 million years ago (the Eocene epoch), the Arctic was not a frozen tundra -- rather, it was more like a huge temperate forest with brackish water.

A new study, the most comprehensive ever on seasonal distribution patterns and historic trends in abundance of white sharks (Carcharodon carcharias) in the western North Atlantic Ocean, used records compiled over more than 200 years to update knowledge and fill in gaps in information about this species. Scientists from NOAA Fisheries and colleagues added...
