Update: Histogram added at bottom.

NOAA September 2012 – Ordered By Rank out of 118.  No State broke the record for its warmest September.

As an example, Indiana had the 30th warmest September, meaning 88 were warmer. The warmest September for Indiana was 1925 — 8.1F warmer than 2012!

Minnesota and North Dakotas record for September is 1897! Arizona’s is 1899.

USCRN vs NOAA September 2012

Published on by sunshinehours1Leave a comment

USCRN vs NOAA September 2012 update.

The USCRN is a new ‘state of the art’ United States Climate Reference Network. The USCRN “consists of 114 stations developed, deployed, managed, and maintained by the National Oceanic and Atmospheric Administration (NOAA) in the continental United States for the express purpose of detecting the national signal of climate change.”

This is the monthly Mean from both NOAA and USCRN for September 2012 for the 48 continental states.

16 states show USCRN stations warmer than NOAA (bold) and 32 show NOAA warmer than USCRN.

NOAA – USCRN = NOAA state temperature average minus USCRN state temperature average.

Ignoring area weighting, the NOAA temperature averaged 0.80F warmer than USCRN.

September 2012 was 3F colder than September 1998. The trend for Septembers since 1997 was dropping -.31F / decade.

From 1895 to 2012, 22 Septembers were warmer (1998 was the warmest).

Some of the warmer Septembers were: 1931,1933,1939,1922,1925,1938,1921,1947,1897,1954,1960,1963,1936,1906.

USCRN vs NOAA August 2012

USCRN vs NOAA August 2012 update. (I’m late because USCRN didn’t post August monthly temperatures until October 3rd after they posted September data).

The USCRN is a new ‘state of the art’ United States Climate Reference Network. The USCRN “consists of 114 stations developed, deployed, managed, and maintained by the National Oceanic and Atmospheric Administration (NOAA) in the continental United States for the express purpose of detecting the national signal of climate change.”

This is the monthly Mean from both NOAA and USCRN for August 2012 for the 48 continental states.

14 states show USCRN stations warmer than NOAA (bold) and 34 show NOAA warmer than USCRN.

NOAA – USCRN = NOAA state temperature average minus USCRN state temperature average.

Ignoring area weighting, the NOAA temperature averaged 0.83F warmer than USCRN.

WOW!!!! Antarctic Sea Ice Extent All Time Records Set in 2012

Published on by sunshinehours128 Comments

Update: Take at look at the amazing AMO vs Arctic vs Antarctic graph here.

As you may know, I have been using Cryosphere’s Antarctic Sea Ice Area data to show the record levels of Antarctic Sea Ice.

But I just found another data set, NOAA’s Sea Ice Extent here. (thanks to commenter HaroldW at the Blackboard)

And it turns out day 265 set an all time record, and then day 266 broke that record. Days 265 through 270 are now the 6 highest Antarctic Sea Ice Extent’s of all time!!!!

11 of the top 15 are now 2012.

Anyone wonder why NOAA isn’t making a fuss about this?

NOAA Temperature Trends Per State as low as -249.5F / decade

Published on by sunshinehours1Leave a comment

Using data as of Aug 2012, these are the NOAA temperature trends (in Fahrenheit per decade) 6 months ago to present, one year to present etc. (Of course the NOAA data may be heavily adjusted upwards)

Notice the 6 month trends for most states are amazingly low such as Iowa’s -249.5F / decade, which of course was caused by the very unusual warmth in March 2012.

But if you look all the way to the right at the 15 year trends, even with March 2012 being so warm, there are still 20 states with a negative trend.

And then looking at the 6 month trends that are hugely positive like Washington and Oregon caused by a very warm August.

1934 as Art (NOAA data)

Published on by sunshinehours1Leave a comment

Here is 1934 graphed using data from NOAA (continental 48 states). One line per state. Each months anomaly from the 1895 – 2012 average for each state. Click on it for a larger version.

Notice how each month there are dozens of states temperature moving in the same direction, but there are large numbers of states going in the opposite direction.

Notice how one month into 1934, half the states were -10 to -14F colder than the long term average and others were over 5F above normal.

USA States Months Ranked 10th Coldest or Colder Occuring This Century

Published on by sunshinehours1Leave a comment

Using data up to Aug 2012 from the NOAA, these are the months ranked in the coldest 10 for a state that occurred this supposedly warm century (2000 – Aug 2012).

If Rank = 1,  it is the coldest. The Anomaly is the difference from the 1981 to 2010 30 year average.

For example, Nov 2000 was the coldest November in Arizona as long as NOAA has put out data (since 1895). The average temp was 44.2 which was -6.5F colder than the 30 year average.

At the bottom is a list of anomalies -10F or colder that occurred since 2000.

Amazingly, North Dakota 2002 Mar had an -11.1F anomaly and it was only ranked as the 9th coldest March with an average temperature of 16.2F. Brrr.
