It's also OK that most nurses and primary school teachers are women.

If you don't want to seem condescending going forward, you can safely assume that anyone who specifically uses the term AGW instead of global warming or climate change knows everything you said in your reply.

It's possible that both the AGW deniers and AGW alarmists are wrong. Climate change could be real, but caused by natural factors that are out of our control, the same ones that have caused ice ages and warm periods in the past when carbon outputs were nowhere near as high as they are now. But that theory would cause people to stop paying their taxes and mortgages and move to the tropics, so we can't have that.

Did anyone else get an email from them offering free credit monitoring?

I used to live in Detroit and can confirm. This time of year it's normal for temperatures to remain below freezing for days at a time, if not months. Temperatures remaining below zero is rare, but did happen for a week a couple of years ago.
