"It's global warming really super hard"

This is what one of my 9th graders said to me yesterday. The students are saying it's more like May than December with a high of 40 the other day and temperatures above 30 for most of the week (that's without wind chill factored in of course) and all of the sea ice melting. That doesn't sound like May to me but I agree that it's global warming really super hard anyway. (Though random fluctuation of day-to-day temperatures is not really evidence of global warming, of course.)
