HADCET – Top 18 Year Warming Trends By Month

Yesterday I did post about HADCET data by month showing how some of the months have a 350 year flat trend.

Today I thought I would look at the top 18 year warming trends at anytime in the 350 year history of HADCET. Why 18 years? Well, 1980 to 1998 was 18 years.

You might expect them all to be around 1980 to 1998 wouldn’t you? Well, if believe in global warming you might. But if you haven’t been taken in, you might not.

Only one recent month made it in the top. February 1983 to 2000. 2.53C per decade. Helped by the 5th coldest February in 1986 and the 3rd warmest February in 1998. That was an 8C rise.

But the next closest was January 1959 to 1976.  And five of the trends start in the 1600s! One in the 1700s. And four in the 1800s.

There is nothing unusual about the warm in the 1980s to 1990s.

  1. OT: What the hell has happened to the ice data now? Are the satellites down from solar storms, or are they just hiding or manipulating the data?
