Is this evidence that supports the theory of global climate change?

This Yale Environment 360 blog post reports a story from the Guardian UK newspaper which suggests that this phenomenon may cause the extinction of the Alaskan walrus population.

Walruses Abandon Ice
And Move En Masse To Coast of Alaska

An estimated 10,000 to 20,000 walruses, mainly mothers and their calves, have abandoned the shrinking and thinning ice of the Chukchi Sea and hauled out on the Alaska shoreline, according to researchers from the U.S. Geological Survey (USGS).

  1. Seems like the ice has been there for long enough for the walruses to evolve to live on it. Now that the ice is disappearing the walruses will need to adapt to living on the coast or they will go extinct. It seems like there must be warming, and it seems like the warming has happened since people started burning lots of fossil fuels. Lets do the experiment to see if burning less fossil fuels causes less warming.
