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!

The Warming Hole – Arkansas – NOAA

So I’ve been looking at the NOAA data. Today it is Arkansas.  The settings I use are:

And the results are quite interesting.

The NOAA says Arkansas has been cooling since 1895 by -.03F / decade.

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

1) The warmest year from this century was 2006, 99 out of 117th. 18 years were warmer.

2) 1896 was tied with 1934 for 110th out of 117.

3) 1897 was tied with 2011.

4) CO2 is one wimpy GHG in Arkansas

What does NOAA mean by “Near Normal”?

Yes I know that most of the USA was warm in March of 2012. But what does the NOAA mean by “Near Normal” in the North West and West regions?

In the North West, March 2012 was the 72nd warmest March out of 118. 118 is the warmest. It was 7F colder than 1934 which was the warmest March.  7F colder. Wow.

The North West has been cold recently. March 2011 was the 64th warmest, 2010 was the 91st warmest, 2009 was the 26th warmest and 2008 was the 31st warmest.

92 Marches were warmer than 2009. 2009 was 9.6F colder than March of 1934.

In the West region, March 2012 was 76th warmest.  It was 7.6F colder than 1934, again the warmest March.

But take a look at 2006. 7th warmest. 111 were warmer. The last 5 years have been quite cold.

1934 sure turns up a lot as the year with the warmest month.

Wait until we took a look at April. I’ll give you a hint. 5th and 6th warmest out of  118 in the last 4 years. 112 and 113 warmer Aprils.
