The European Space Agency (ESA) is offering a free online course, where "you will join leading experts and scientists from ESA and key European research centres, to explore the science that underpins Earth observation. We will look at recent and current satellite missions that are providing an archive of essential data; and find out how this data is used in local and international policy and planning."
The course starts on November 30, lasts 5 weeks and involves 3 hrs per week. It's possible to get a certificate.
This sounds like it would be of interest to teachers (geography, science, politics), people whose work involves relevant policy making, and people who are just interested!
