[AT] Good tractor day

[Mattias Kessén]

 It's pretty obvious that it's not particulary warm or cold right now. 1000
years ago it was a lot warmer here and 10000 years ago it was covered in a
thousand metre icelayer and 1.7 billion years ago it really was warmer and
covered with ash from the Volcano south of here. Of course here was
somewhere in the pacific ocean then so what is normal? We have the
possibilty to compare with 150-200 years old pictures and measurments but
that is as intresting as comparing with yesterdays weather (+2 degrees and
stopped raining!)
