Just for kicks, I've knocked-up a quick php page which shows sea ice concentration for the northern hemisphere. It fetches images from the University of Illinois at Urbana-Champaign Polar Research Group's "The Cryosphere Today" website and displays one from the current day (or the previous day) and one for the same day in 1980 (if the image is available).
The idea is that you can compare the sea ice extent and see how badly global warming is getting.
By the looks of things, I'd say not very, but we'll have to wait 'til the summer (northern hemisphere) to see a dramatic difference I think.
The main need for php code was to find a suitable image should there not be one for the current day (it will display one for the previous day) or for the same day in 1980 in which case an image for the most recent image prior to that date will be displayed.
I don't do a lot of php code so this was fun. I even did it in an OO stylee.
