 A record-breaking heat wave is scorching the West. Over 70 million people are under heat alerts, with about a dozen California cities breaking all-time high temperature records. There have been at least four heat-related deaths in Oregon since July 5th. Chinese military ships were off the coast of Alaska. The U.S. Coast Guard says all four were in international waters, but inside the U.S. exclusive economic zone, which goes out about 200 miles from the shoreline.
