The Arctic sea ice has been seen to be in steady retreat since about 1950, a retreat which has recently sped up with an additional factor of thinning. In summer now there is only a quarter of the volume of ice that there was in summer in 1980. This process shows every sign of continuing, so that the Arctic will be ice-free for part of the year. Obviously we view this as a product of global warming, but why should it concern us in other ways?
“The world is facing a catastrophe.” It is too late for individuals to make a significant difference in the preservation of ice caps. At the current rate of global warming, government intervention is needed. In the following video and excerpt from A Farewell to Ice, Peter Wadhams, one of the world’s leading experts on polar ice, discusses the role that governments around the world need to play in order to combat global warming.
The ice caps are melting. Within a few years the North Pole will likely be ice-free for the first time in 10,000 years, causing what some call the “Arctic death spiral.” In the following excerpt from A Farewell to Ice, Peter Wadhams explains what we can do today to fight climate change. What can we do, both individually and collectively, to try to save the world? There is a massive list, of course, but I will pick out a few actions that might make a real difference.
