I doubt he was.
Several cases of Polar bears having been found drowned as the sea ice pulls farther back have been discovered in the last few years, and published in peer-reviewed sources such as
"Nature" as well as newspapers such as "The Washington Post" and news agencies such as
ABC News
Aside from this obvious cause of harm to polar bears, there's also the fact that most of a Polar Bear's winter energy stores is gained via jumping from ice drift to ice drift fattening up on seals... something's that becoming less and less doable every year - meaning less stored fat, meaning less survivability and less milk production and reproductive success.
I think that it was incidents such as 4 drowned bears found in open water in 2004 that sparked the 3-year study that resulted in Polar Bears being declared an threatened species in January of this year.
As the San Francisco Chronicle put it - "the first mammal deemed in danger of extinction because of global warming."
