The Warming Hole – Tennessee – NOAA

This is the 2nd of a series of … until I get bored with it. 🙂

There is an article on WUWT called “Drats! Down the warmhole the warming went” about a new paper from Harvard:

“Climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered that particulate pollution in the late 20th century created a “warming hole” over the eastern United States—that is, a cold patch where the effects of global warming were temporarily obscured.”

The argument is essentially that the air pollution over the northeast USA kept temperatures artificially cool until clean air legislation in the 1970s – 1990s time frame.

So I’ve been looking at the NOAA data. Today it is Tennessee.

And the results are quite interesting.

The NOAA says Tennessee has been cooling since 1895 by -.03F / decade. Which is the same as Arkansas.

Changing the criteria to Table and Rank, here are some things that jumped out at me.

1) Only 1 year from this century made the top 10 – 2007

2) 2011 is at position 88 out of 117

If you sort by year, 2010 was 46 out of 117 and 2009 and 2008 were 36 out of 117. Those are really low scores!  It has been a cold century in Tennessee.

Take a look at the bar chart. CO2 is the wimpiest GHG ever! The 20s and 30s and 40s were hot compared to this whole century.

You have to wonder why all that sulphate in the air totally neglected to effect Tennessee until 1960!
