Good reader in the Washington Times about the territorial disputes in Canada caused by increasingly accesible water routes:

An open Northwest Passage would cut 5,000 nautical miles from shipping routes between Europe and Asia.

If the passage’s deep waters become completely ice-free in summer months, they would be particularly enticing for massive supertankers that are forced to plow around the tip of South America because they are too big to pass through the Panama Canal.

For the record, I’ve no dispute that global warming is a real phenomenon; I just object to the knee-jerk conclusion that it’s caused by humans and their industrialization. The Earth has warmed before — even when there were no factories to blame.
