An illustrated talk by Dr Andrew Bell (retired geologist and former Open University lecturer)
on Thursday, 30th October 2014 at 7.30pm
Over the last 500 million years, Eden has variously been a sandy desert, lainat the bottom of a deep ocean, been a tropical island paradise, and been covered by a thick ice sheet.
At times in the geological past, British sea level stood over 100m higher and air temperatures were 15 degrees C higher than they are today; then our dry-land area was reduced to half what it currently is. At other times, air temperatures were 10 degrees C lower than today, sea level was very much lower , and almost twice the acreage of dry land was exposed.
Today, the issue of our changing climate, and human's part in it, is a topic of hot debate.
What can we learn from studying the Earth's past? Can we be sure of what the future holds? Or is it all simply hot air!
This talk looks at the scientific evidence for past British climates in a simple and straightforward way, and reaches compelling conclusions that arise for a comparison of today's atmosphere with those of the deep past.
