This is an email sent to me by James Halfpenny with regard to the ice in Hudson Bay and other important data.
Due to being unable to upload pictures direct to the forum I have had to change the email slightly and add links to the bottom of the email to the pictures and pdf document.
Thanks to Janet for the info and help on how to do this.
The email text is next, followed by the links to the various information graphs and illustrations minus one link Jim sent which includes books for sale which violates our forum rules.
This is the end of 2015 year sea ice report for Hudson Bay. I apologize if you receive more than one copy of this email, it simply means you are on more than one of my lists or have multiple email addresses listed with me. The message is too important to miss anyone. Please circulate the content, especially on climate change.
The first figure below is from November 20, 2015. It shows ice thickness off the shores of Churchill as covered by 9 to 10/10ths ice. A short distance out there was still open water.
Figure 2 shows there was still open water but quit was distance out in to the Bay.
It is significant to note that the ice edge was far enough out into the Bay on November 30 that the bears had gone significantly far from land. The leading edge of the ice is a great hunting ground as seals come up on the ice to rest and bears can successfully take them.
Even a quarter mile of hard ice is enough to aid hunting. It is difficult to tell from the map how wide the Nov. 30 band is but it is miles wide. By Nov 30 all bears were gone from shore.
Complete freeze up of Hudson Bay takes well into then next year and as you see it is still under way.
The graph (Nov 28, most recent available) shows that sea ice freezing is well ahead of average with a great percentage of the Bay frozen than average. This is good for this years polar bears but I fear not a long-term trend with the warming Arctic environment.
I have attached a great PDF for your reading, Arctic Matters: The global Connection to Changes in the Arctic. (Jim, your attached PDF is the same as the Royal Society web page link so I have left it off) Please take a moment to go to the following link to investigate a plethora of FREE publications (search climate change) by the National Academies of the United States of America.
Also please check out the link below to the Royal Society and download the publication called Climate Change: Evidence and Causes. They also have other great FREE downloadable publications.
