Everytime I hear the word 'manhole' I think I have a hearing problem, or that my English is really, really bad. It sounds like a word I should understand, consisting of the two well known words 'man' and 'hole' , both of which give perfect meaning. The reason why I think 'manhole' is so weird, is that the combination doesn't give an immediate logical meaning. It is too ambiguous for that; a hole made for a man? or by a man? maybe even a certain hole in a man? For those of you who share my resistant linguistic ignorance, here is a picture showing what a manhole really is – so we all know what we are talking about in the continuing.
Today you'll find a myriad of different Earth observation systems covering all from local to global areas, collected from sub-sea to ground to air and of course space. Providers of these Earth observation services come from both public and private sector. Some of the collected data are required through national regulations while others are in demand because of global challenges such as climate change etc. The need for Earth observations permeates the entire global society.

Answering this need for Earth observation capacity several Earth observation systems have been built.

Between physicists - there's an Easter bunny! Last Friday I went to Oslo, you know, the capital of Norway and home of the Vikings, to meet experimental physicist Tommaso Dorigo. Tommaso, who writes A Quantum Diaries Survivor  here on Science 2.0 had a few days earlier announced that he planned a visit to my country and asked for advise on what to see with his family while he was here.
 Last week-end I was being a good mother and drove my son to a party. We took off not long after the Sun had set. The last few evenings and nights have been crystal clear and completely mesmerizing here, on the countryside a little north of Oslo, Norway. This Friday was no different. As we approached the destination I noticed a very bright light in the sky. Even though it's been a while since I was a professional astronomer or astrophysicist, I maintain my habit of checking out the night sky (read: I do it ALL THE TIME) making 'meaningless' remarks about my observations. At least they are percieved as rather dull and meaningless to whomever I senselessly talk to, constantly forgetting that they do not care that much about extraterrestial matters as I do.
Do we really care about climate change? Since we do very little to reduce or limit activities that we believe we know cause climate change one could argue that we - do - not - in - fact - care.

Come again?!

I can almost hear you say.

At a AGU Town Hall meeting in San Francisco last night a group of engaged scientists discussed "Directions in Climate Change Education and Communication"

In the AGU program this meeting was introduced the following way:
Earth Science Bonanza is the best way of describing a meeting where 20 000 Earth science scientists gather from around the entire world. For a whole week San Francisco is saturated with scientists. The highest density can be found around Union Square more specifically at Moscone center. The yearly AGU Fall meeting has started....
