Interesting thought on climate change

I just read a very interesting article on telepolis.de:

-> http://www.heise.de/tp/r4/artikel/29/29276/1.html

It is an Interview with the future scientist Matthias Horx.
In the context of crisis entertainment - entertainment out of natural catastrophes, like seen on the mass media - the Interviewer asks, to what degree the climate change discussion is a type of "crisis entertainment".

He asks a question (which I also asked my self before), why the climate change is bad per se? He points to the 11th-13th century, where it was so warm, that the vikings were able to do farming in greenland for example.
He goes a littlebit deeper and assumes that they are maybe "collective psychodynamic functions" (thats my translation from german of that contruct?!), which leads people to create a punitive measure on the future. He connects that to occidential religios influences, where those punitive measure is a main function of.

I know that sounds to many people in the moment just rediciolous... to me also! But on the other side, I can't deny a glimpse of truth in that assumption?!
