More Global Warming

It snowed up here, light, only 1/4 inch, but mid May is very late for snow, even in New Hampshire.  Clearly global warming at work. 
Then my electric bill shows power use by month over the last 12 months.  This year, May 2016, average temperature was 43F and my daily power use was 19 KWH.  Last May, it was 57F and daily power use was 15 KWH.   More global warming at work.
