Yet another exploration of how remote sensing by satellites is helping researchers learn more about what’s happening here on Earth. The beauty of it is that satellites work around the clock making images and taking measurements to degrees of accuracy we could never imagine in the past.
Put all those snapshots and measurements together over time and we end up with a reality far better than any model. This video shows quite well what is happening to ice in the Arctic and Antarctic: Ice Sheet Thickness from Satellite Observations – brought to you by the European Space Agency.

Our European friends certainly rely on the wonderful warmth brought tot them each winter by the Gulf Stream – North Atlantic Drift. I lived in Germany for three years and in England for another three years and in all that time, I think I saw snow on the ground for a total of two weeks (other than when skiing in the Alps!). Despite being further north than where I am here in southern Ontario, Western Europe just does not get snow on a regular basis – all thanks to the Gulf Stream – North Atlantic Drift warm ocean current.
But all that could change… When we lived in England a few years ago, there was talk of how the melting of Arctic ice due to Global Climate Change could shift the North Atlantic Drift southwards. This video – The Gulf Stream and the Next Ice Age – explores that possibility. Although 52 minutes long, and a bit repetitive (as made-for-TV documentaries often are), it is a good watch and has some very good footage and graphics to share with classes.
