I hope you all had a nice time the last few days.
It has been a bit hectic here, with kids and visitors coming over. This by way of a poor excuse for not responding sooner on your replies.
I have been reading a bit up on the possible effects the increase in greenhouse gasses could have on Ocean currents. Not unexpectedly it seems to be a very complex issue.
All that fresh meltwater coming from the Antarctic and Greenland is likely to have an effect on the Ocean currents. It is difficult to see how they could not be changed by this. Also a rising sea level and a melting of the ice in the summer between the Canadian arctic islands is going to change the currents there. I am not sure if that would result in a north or south flow. But with a warmer Arctic Ocean it might end up in an increased south flow of warmer water down Davis Straight. Could add to the interference of the Gulf Stream.
