Monthly Temperature Trends for the past 112 years
Global warming theory says that the warming is not even throughout the year so lets take a look at the monthly temperature trends. The monthly plots from 1895 to 2007 and year to date 2008 are below along with their calculated trend line.
January
The January plots include 2008 and show three graphs with trend lines. They are long term of 113 years, intermediate term of 30 years and short term of 10 years. All three graphs are still indicating increasing temperature trends.

Summary
Summary of the annual average temperature trend by month for the past 112 years

Well that's interesting but how does this effect the people of New Hampshire. Our heating and cooling bills are definitely the the first things that come to mind, first let's look at the way that our energy suppliers determine how much energy we use by looking at Heating Degree Days (HDD) and Cooling Degree Days (CDD).
