detachment

of course I know about scientific objectivity, but still I find it a little strange how different environmental scientists are from activists. While climate change is irrevocably changing the Arctic environment they also see the benefits for some species (the narwhal can now swim through the North West passage, the Caribou has more grazing area, and of course the Greenland people are benefitting from more crop growing conditions. The loss of some species through greater competition? - well that is the dynamics of biology! For some wading birds who already live on the edge of the limits of existence, there is nowhere to go as their habitat disappears. Peter also notes that the millions of humans who are living at the limits will suffer as temperatures rise, not only the islanders but those locked inland in the vast drying continent of Africa.
