Positive economic impact of global warming

Treehugger reports that the search for the northwest passage is almost over. According to the US Snow and Ice Data center, "Analysts confirm that the passage is almost completely clear and that the region is more open than it has ever been since the advent of routine monitoring in 1972." The article didn't mention that people have been searching for the northwest passage for hundreds of years. Think of all the increased trade that can take place now.

In all seriousness, this is troubling. I report this just to demonstrate the far reaching implications of global warming.
