Rose Harris Googe “Jellyfish Swarm Northward in Warming World” USA Today 11/16/09 loc=interstitialskip This article deals with the growing and migrating population of jellyfish in the world, primarily those off the coast of Japan. The jellyfish are causing problems in the fishing industry and as the waters are warming, their habitat is expanding and moving northward. They get trapped in the fishing nets and kill or taint the fish. This problem is hurting a once successful industry and lobbyists are calling for help. Unfortunately, the only thing that can reverse the damage would be lowering ocean temperatures and that would take years, if it could be done at all, to accomplish.

While this is a compelling story and a very interesting one as well, the author doesn’t have a lot of scientific information to back it up and most of the information provided is primarily anecdotal.
