USCRN April 2013 – 41 to 9 ratio of coldest Aprils to Warmest April

The USCRN is a new ‘state of the art’ United States Climate Reference Network.

There are 222 stations of which 220 have data for April 2013. Of those 222, only 137 have 5 or more years of data. I’ll be using the 137 list.

41 of those 137 had April 2013 as the coldest April.

9 of those 137 had April 2013 as the warmest April.

HADCRUT4 4.2.0.0 versus HADCRUT4 4.0.0.0 Global

HADCRUT4 is now at its 3rd iteration. It started with version 4.0.0.0 and then version 4.1.1.0 come out. As of the latest data it is at 4.2.0.0.

I thought I would compare them. Here is the difference between them ( 4.2.0.0 monthly anomaly minus 4.0.0.0 monthly anomaly).

If the bar is red, the newest HADCRUT4 is warmer. If blue, then the newest data is cooler.

This is the data from 1950 on. Note that the values are pretty low and relatively evenly divided between blue and red.

Until 1997. Then the values are a little larger (still relatively small).  And almost all red.

They are warming the most recent temperatures again! Give them a few years and the pause will disappear.

If Arctic Sea Ice Is In A Death Spiral Why is 2013 The 12th Lowest And Not The Lowest?

What a strange death spiral for Arctic Sea Ice.

There are 11 years with less ice at this day in the year: 2006, 2004, 2007, 2011, 2003, 1989, 2005, 2002, 1996, 2010 and 1995.

HADCRUT4 March 2013 – Cooling at -0.292C / Decade for last 4 years

HADCRUT4 March 2013 data is finally available. Remember that the anomaly is the difference from the 1961-1990 average.

The global data shows cooling at -0.292C / Decade for last 4 years. (Click to make bigger)

For those who think 4 years is too short, the global data shows cooling at -0.034C / Decade for last 12 years.

Where is the Data? UAH, HADCRUT kind of late

2nd UPDATE: UAH is out. My post here.I knew if I complained it would all show up.

UPDATE: HADCRUT4 for March 2013 is out. My post is here.

Anyone know where the UAH and HADCRUT data is?

While some of the UAH data arrived a few days ago, the downloadable file is still missing April’s data. March’s data arrived April 2.

HADCRUT is usually available by the 28th of the following month. February’s data came out March 28. It is now 10 days late.

Are they having a conference? March and April too cold to explain?

RSS is out. HADCET is out. NCDC is due soon, but not overdue.

HADCET April 2013 – Tied With 1671,1674,1676,1677,1692,1694,1698,1712,1714,1717,1718,1720,1722,1745,1753,1765,1857,1859,1861,1902,1911 and 1925

HADCET April 2013 average temperature came in at 7.5C.

2013 was tied with 1671,1674,1676,1677,1692,1694,1698,1712,1714,1717,1718,1720,1722,1745,1753,1765,1857,1859,1861,1902,1911 and 1925.

Arctic Sea Ice 2013 – Where is the Death Spiral?

If someone claims Arctic Sea Ice is in a death spiral, you can mention that right now 2013 is the 7th lowest and not the lowest.

And that 2013 has even more ice than 1989 at this point in the year.

Lowest 7 = 2006 2004 2011 2007 1989 2005 2013

And that Extent is within one standard deviation of the 1981 – 2010 mean. And only 340,000 sq km below the mean which is about 2.5%.

 

Canada April 2013 – Really, Really Cold in the Middle

According to the Environment Canada “Normals” (the stations EC calculates anomalies for) , Canada was colder than the 1971-2000 average in April 2013.

The mean of all the “Normals” was -1.83C colder than 1971-2000 average.

If you look in the top left corder of the anomaly map and note the black circle represents 5C anomalies. Blue is colder than normal. Red is warmer.

The middle of the country was really, really cold. What little warmth there was, was concentrated in a handful of arctic stations.

And many of the stations had values too small to really show up on the map.

The anomaly map for April 2013 follows. Click to make it bigger.

Where do I get the data? From Environment Canada monthly summaries.

The URL for April 2013 BC data is here. You can replace BC with nothing (PROV=) or SASK or MAN etc.

I use the data with a D column  value because EC calculates the anomalies for me. And because they are supposed to be better/long stations.

I Smell A Rat at NSIDC – Earliest satellite maps of Antarctic and Arctic sea ice

At the bottom of this post is a screen capture of an article at NSIDC concerning some early satellite pictures of the Arctic and Antarctic.

The article is titled “Earliest satellite maps of Antarctic and Arctic sea ice”.

Go ahead an read it at NSIDC (link) or in the screen capture.

Some things jumped out at me right away:

1) The Antarctic data is very specific comparing September 1964 to September 2012 and August 1966 to September 1986.

2) Why did they compare August 1966 to September 1986? The lowest average for August is 1986, but it was 17 million sq km, not 17.5 million.

3) The 15.9 million sq km for August 1966 is 1.1 million sq km lower than the lowest “modern” mean for August. Which means Antarctic Sea Ice has been growing since 1966 (at least in August).

4) Why are they so incredibly unspecific about the Arctic? “early satellite data” for September is compared to  “broadly similar to the 1979 to 2000 average”. Why not give values for specific years?

5) 6.9 million square kilometers for some September in the 1960s would be 700,000 sq km lower than the highest Arctic Sea Ice which occurred in 1980. Isn’t that evidence of Arctic Sea Ice being cyclic?

6) I smell a rat. Why so ambiguous about the years in the Arctic? What are they hiding?
