Wrong conclusion

I read an article about an Alaskan island that is losing ground, and of course it is blamed on global warming. Even if they do have the right data, they have made a wrong conclusion. The landscape of the Earth has been changing for millions of years. It changed a lot even before we had the technology of the past hundred years that they claim is causing global warming. Areas of the coasts have been lost, and areas of the coasts have gained ground. At one time all the earth was one land mass. Surprised they don't blame global warming on the land splitting and forming the way it currently has.
