Why are scientists carrying out polar research in the 21st century ?

Our etwinning project tries to answer this question through interviews of scientists involved in the International Polar Year.
These interviews are presented here grouped by research topic.
If you want to view them in chronological order or download mp4's for your ipod, please check out the main project page.
We presented this project at a scientific forum in Berlin, in November 2007.
