If it's a problem, act like it's a problem. Various sources are reporting that Bernie Sanders, the aged socialist from Vermont, and climate hawk, spent $300K on private air travel in October.

I'll start to consider climate change a problem, when you start acting like it's a problem. Until then, you should just shut-the-hell up about it.
