Found a new website: http://www.globalwarmingscientist.com/ which updates northern and southern hemisphere sea ice coverage plots giving users the most up to date idea of how the earth is reacting.
This site also updates static images I noticed, so to get the latest image for the northern hemisphere you can use:

or

Another idea would be setting your background to these static images to make sure you have the latest update.
