Having just returned from a visit to Iceland where global warming is really affecting them, though at minus 17 on some days it was cold enough for me. The saddest thing, which has really played on my mind is that Polar Bears are now finding their way to Iceland on ice caps and as the animals cannot be trapped or captured safely they are therefore killed. I have a real issue with this and how the polar bears in particular are being affected by global warming, it really breaks my heart.
