I had a co-worker about ten years ago angrily respond to another co-worker who was joking about "where's the global warming?" during a brutally cold winter with "It's NEVER been 'global warming', it's ALWAYS been 'climate change'."
My one regret was that I was literally too shocked too laugh derisively, much less point out that, in the 70's and 80's, it was actually "global ice age".
