Mon 30th October 2017 at 18.30 - 21.00
INVITE YOUR PARTNERS & GUESTS. A tasty meal and a talk. Speaker Host - Roger Birchinall, General Host - Bob Sadler, Cashier - Maureen Hallsworth.
Back by popular demand the polymath Hugh Hunt will talk to us today. Title - 'Can the Arctic be Refrozen ?'.
This evening we had a fascinating talk, if rather depressing, about the drastic action that is needed by governments across the world in order to redress the undeniable warming of the earth. Hugh showed how the warming is now relentless rather than transatory. For example the Arctic ice is thinning and shrinking at an alarming rate, releasing methane from the permafrost on the sea bed which is accelerating the problem. He explained that much of the worlds fresh water was locked in the polar ice caps and that when they melt a sea level rise of up to 8 metres is expected - in this area this would mean our coasts will shrink and the Wash would expand far in land and sink the fens again, while countries like Bangladesh and Holland will be submerged.. He sees this as a problem that we are bequeathing to our Grandchildren.
