I sure wish Clark Public Utilities would do that for us, but they would probably raise rates another 5% to pay for it.
I made a spreadsheet just to see what I had. It gave me 45 months of continuous data. Because I don’t have the stuff from 2006, I only got 37 months of Delta (this months temp versus same month last year).
Am I seeing global warming?
Well, not really. 37 months of delta added up to a total delta of -18 degrees F. So it would average out for three years to be, each month, about 1/2 degree cooler than the same month last year.
Highlights:
Spring 2008 (Apr, May, Jun) was quite a bit warmer than 2007 with a total delta for the 3 months of 14, or about 4.6 degrees per day. Spring of 2009 came back and probably ended up averaging out by being cooler than 2008, with a delta of -14 for the 3 months.
Winter 2008 and winter 2009 was about 2 degrees cooler than previous years. But winter 2010 really warmed up with a delta over 2009 of 15, or about 5 degrees F per day. After that, it cooled alot, with the delta for the next 5 months being -15, or 3 degrees per day for spring/early summer 2010.
The only thing that gave us any kind of summer at all was Sept, which was up a whopping 8 degrees per day over Sep of 2009.
So besides from a warm winter, probably because of El Nino, and a warm Sept., this year was cooler than usual.
