Would you want your hospital reliant on wind turbines that can’t handle 50mph gusts?
“A 35-metre turbine has collapsed near Holsworthy leaving the tower lying on the ground. The turbine at East Ash Farm in Bradworthy was erected in 2010 by Dulas Ltd. Dulas confirmed this morning that an “incident” had occurred with the turbine and said the situation is currently being investigated”
Tom Nelson has a blog post pointing out that NASA is claiming the Japan Meterological Agency Global Temperature average “agrees” with the MET and NASA and NOAA.
The trouble with that claim is that Japan’s line on the graph shows a sudden .25C downward divergence after 2000.
As Antarctic Sea Ice approaches minimum for the year, Antarctic Sea Ice for Day 26 is the 4th largest amount behind 2008, 1995 and 2004.
The way things are tracking there is a good chance a record for most ice at minimum may be set.
Has the AMO Peaked and started its drop towards negative? The answer is yes for winter months and no for summer months.
Maybe thats why winter Arctic Ice is doing fine and summer Arctic Ice is not doing fine.
I have included a graph for the AMO for all years that we have data, and then the AMO broken down for each individual month.
The blue boxes in the graphs contain 5 years averages, the blue line underneath is the 5 year period. Red values = above 0 and blue values = below 0.
The All Years AMO has dropped a little over the last 5 years compared to the previous 5 years, but the value is still higher than the 1950 peak of the AMO (but not as high as the short peak around 1878).
It is also interesting that the 1950 peak was in the middle of a 35-40 year period above zero and the current peak is only 15 years long. The AMO may still have decades left above zero, but the winter months look like it was a shorter peak.
May to October 5 year values are still higher than the previous peak around 1950.
November to April have dropped and are now lower than the previous peak around 1950.

I have mapped the anomalies in the Environment Canada monthly summaries that have “normals”. The anomalies are calculated from selected stations based on the 1971-2000 average.
The 5C black dot in the top left hand corner represents 5C difference from “normal”. Red dots are warmer than normal. Blue are cooler. And Green are 0.
March April and May are really close to normal (all the dots are small). Other months have extremes. October is colder than normal. March is really interesting for having no red dots in the Arctic which means below normal temperatures which has not been true for years.
There is an animated gif at the bottom showing all months of 2012.
HADCRUT4 for the last 12 years shows a small amount of cooling. The following map shows which 5×5 grid squares are warming or cooling. I am using grid squares with 130 out of 144 possible datapoints for the period. The circles are proportional to the trends. Keep in mind that this is 5×5 grids squares. As I’ve shown for Canada different size of grid squares change warming to cooling.
Thanks to the big drop in Dec 2012, HADCRUT4 has a negative trend for 12 years.
-.012C / Decade
HADCRUT4 for Dec 2012 is out. The anomaly was .269C.
I looked at HADCRUT3 in a previous post.
Here is a list of months with a warmer anomaly than Dec 2012 that came before 1990.

HADCRUT3 for Dec 2012 is out.
Dec 1939 was .112C warmer. And 1979 was warmer. And 1981. And 1987.
Notice how 2010, 2011 and 2012 are at the bottom of this list. Three cold Decembers in a row.
Here is the list of Decembers warmer or equal to Dec 2012.

As a follow up to yesterdays post about monthly anomalies in Canada of +15C or higher and -15C and colder, I thought I would take a look what happens if I set the bar at +10C or -10C.
I am using Environment Canada Normals from their monthly summaries. The values are the anomaly from the 1971-2000 average (the Normals).
In 1936, 3.6% of the monthly anomalies were -10C or colder than normal.
A -10C or lower deviation from normal for a whole month is definitely extreme!
And notice 1982 is the most recent year to make the top 25.

Hot Anomalies are much rarer.
Only .688% of the anomalies were 10C or higher in 2006. Thats less than 1/5th of the largest percentage of cold anomalies. It was also 6 years ago.
