The last 10 years or so I have been working on various aspects of the environment. Though my main perspective has been scientific, the political framework set the scene and define the premises for even scientific discussions, particularly when it comes to funding.

I remember when water bottles were introduced on the Norwegian market. It was the most stupid idea I had ever heard of and could not imagine how anybody would be willing to loose their money on this bound to fail business project. Obviously I was wrong. Even in a clean country like Norway where fresh water is abundant everywhere there was a market for bottled water. Go figure.
The oil spill in the Gulf of Mexico is nothing but a plain disaster. It was of course a topic at ESA's Living Planet Symposium in Bergen this week, where use of satellites to help mitigate this environmental - and economic - disaster was on the agenda. But this is not about the science nor the politics of the oil spill.


Satellites are being used to look at practically everything you can think of. Well, maybe not. But if you take a single subject like ice, it is amazing how many ways you can look at it with a surprisingly large number of satellites.

A random visit to a session or two here at the ESA Living Planet Symposium in Bergen show a small selection of ways to look at ice from space.

ESA and friends are celebrating the success of the Living Planet program in Bergen Norway this week. It cannot be described as anything but a success actually, with a number of new advanced and innovative Earth observation satellites in orbit performing not only on target, but exceeding expectations.
