Just a quick comment triggered by postings above regarding the icecap extending to Iceland form Greenland. Going back half a century or so,when i was at school,i remember an old weather book showed a map with a dotted line across the North coast of Iceland,labelled "limit of Ice in Spring" Regretably i can`t think of the title and there are no records,i guess,to illustrate those maps now. It does remind me of how the ice has retreated since those days.
