I am attending a major debate on climate change at the Scott Polar Research Institute in Cambridge tomorrow. I will be meeting David Buckland who runs the Cape Farewell project. He has spent the past seven years trying to capture public attention on climate change by leading expeditions to the sub-zero wild and beautiful Arctic on his 100-year old Dutch schooner ship.

There are still many sceptics on climate change, so what are your questions, what should I ask David and other illustrious speakers?
