You might wonder what an aerial picture of an iceberg off the coast of Greenland is doing on the cover of Viva Lewes. I visited Greenland in March, to write a story about the place for the Independent. While there I learnt some alarming things from locals, from geologists, and from other journalists. Greenland is where you go if you want to see the most noticeable effects of global warming first hand. We got taken to the edge of the icecap, and watched a vast cliff-like ice-wall gurgle and melt. We got taken in a boat round icebergs in Disko Bay, and told that they were getting smaller every year, that they used to be twice as big. The temperature was confusing: it hovered around zero, ten degrees above the seasonal average. On the way home I met a hydrologist who told me about the devastating effects global warming will have. “The ice cap will melt, the seas will rise, cities will be submerged,” he said. “We’ve passed the point of no return. All we can hope to do is delay that process.” So what can we do? Well, we can learn more, and we can change our lifestyles. This week, we cover a screening of Al Gore’s film on the subject of global warming, ‘An Inconvenient Truth’. We talk to ecologist Alex Kirby about the need to preserve natural land in the face of global warming, which he will address in his talk ‘Troubles Ahead’. Brian Deval writes an article about car sharing initiatives; Adrienne Campbell writes about her family’s attempt at a waste-free week. We all need to do as much as we can to protect ourselves from what the future may hold. We’re all to blame, after all: it’s clear, for example, that I took the aforementioned photo from the window of a CO2-belching jet plane. Enjoy the week.
