Whihc of these is evidence of global warming a. stable precipitation patterns b. falling global temps c. an increase in the size of glaciers d. overall rising sea levels

I would say perhaps the "falling global temperature" as this should not be behaving in this matter. The warming of the globe should be at a constant temp, one that would be leveled, as we know that the winter should be at the same or around the same temp as last year. And therefore, this would be a near sign of global warming.

C. junior college i hope this .
