. . . the subtle change in language of the "environmental" movement and media? Note that we are no longer threatened by "global warming" but by "climate change."  When did this happen?

Certainly, this will make it substantially easier for the creation worshipers to stay on message if their doomsday prophecy about skyrocketing temperatures doesn't materialize. After all, the climate is always changing, so this adjustment in language guarantees the wild eyed environmentalists permanency.

At least their jobs are secure.
