Global Warming IF it is happening, MAY be a good thing as it may allow previously uninhabitable or barely habitable parts of Russia, Alaska, Scandinavia, Greenland, Iceland, Canada and Antartica to be settled and it will melt the Arctic Icebergs allowing ships to travel from Russia to Canada across The North Pole without Icebergs getting in the way. It may even allow Oil Companies to build Oil Rigs in places that were previously impossible to develop due to ice coverage.
I saw on CNN a documentary about Greenland and how because the Ice Cap is melting away, they have been able to grow crops there that previously would not grow due to the harsh climate.
