By now we all know about Global Climate Change or Global Warming. We know that the sea ice is melting. We know that these changes are happening rapidly and we know that it is putting more and more pressure on the animals that rely on the ice for their survival. However, KNOWING and SEEING FIRST HAND are two very different things.
Churchill is a perfect location to view Polar Bears in the wild. Five rivers pour into Hudson Bay near Churchill, the fresh water freezing at a warmer temperature than the salt water with which it mixes. The polar bears stage in the area, waiting for the ice to form so that they can break their summer long fast by hunting the ring seals which inhabit the ice flows. The large males arrive in the first wave. They spend their time sparing with other males, establishing dominance and working muscles that have been neglected during the summers inactivity. When the ice forms they leave and it is safe for the smaller, younger males and females to stage on the shore before they step off onto the ice flow. The final wave of bears to arrive on the sea ice are the females with cubs. They are vigilant about keeping their cubs a safe distance from large males who are feeling increasingly pressured to find food for their starving bodies.
Historically the bears have been able to return to the sea ice to begin hunting by November 8th. Within the past decade that date has moved further out, the sea ice forming later and later and the multi-year sea ice all but disappearing. On November 19th I was witness to an incident which speaks to the pressures these bear are facing. The ice has yet to form. The area is saturated with bears: large males, thin geriatric bears, slender females, rambunctious teenagers and moms with cubs. They are all starving and they are impatient for the ice to form. A young female was guarding her cub when a large male approached too close. She valiantly fought him, attempting to protect her cub but in the end he was too big, too strong and he took the cub.
This is not an isolated incident. It has been recorded a confirmed four times to date during this season with an additional four unconfirmed incidents - eight in total. Retired biologist, Dr. Ian Sterling has been working with the Western Hudson Bay population of Polar Bears for over 30 years and has reported that he has not witnessed an incident of cannibalism in his time.
It would be easy to hate the male bear, to call him a bad seed and dismiss the incide
nt as the harshness of Mother Nature. In speaking with JoAnne Simerson, Senior Keeper and Polar Bear Behaviorist with the San Diego Zoo, we agree that one has to have compassion for the male bear as well as the cub and female. If his normal food source were available to him he would not have wasted his time on the cub. The world is changing quickly and they all have so little time to adapt....
This December the United Nations plans to meet in Copenhagen to discuss a plan to reduce the world's carbon footprint. I was very happy to learn that President Obama will be attending the meeting and has pledged to reduce U.S. emissions 17% from 2005 by 2020.

Finally some good news for the polar bears. The ice has formed on Hudson Bay and the temperatures are staying low enough to keep the ice so they are on their way!!

Blog Action Day 2009 has got me thinking about Climate Change and my impending visit to the Arctic. For the past few years I have been visiting the Polar Bears of Churchill, Manitoba. They are the Southern-most population and they are being hit hard by the lack of sea ice. Polar Bears are excellent swimmers for sure but with the sea ice disappearing, there is no where for them to swim to... Additionally, the sea ice traditionally holds the sea in place in the Hudson Bay... without it the wind kicks up large waves that even the best swimmers can't fight. The ice that does form is forming later and breaking up earlier... cutting into the bears time limit to capture enough prey to make it through another season. Click here to view an amazing study of the sea ice and it's decline over recent years. Scientists are seeing a trend... bears are getting smaller... mothers are producing single cubs or none at all... One can't help but wonder how long this species has before they reach the tipping point. Here's hoping they can hang on while we get our act together.
It doesn't get much better than this! Just back from Churchill, Manitoba where I spent five wonderful nights sleeping on the tundra with some magnificent animals. 
The accommodations were rustic, a train style bunk bed with barely enough room to sit up but the view from my tiny window every morning made me smile.
All of the bears check the ice as it forms and prepare their systems to eat again. They dig up kelp and chew and chew. Researchers think the kelp provides iodine and perhaps beneficial bacteria which helps to restart the bears digestive systems. One thing is obvious... it gets things moving right along.
