The other day I did a post about HADCET data by month showing how some of the months have a 350 year flat trend.
The next day I did a post about the top 18 year warming trends at anytime in the 350 year history of HADCET.
How about 60 years? Surely the key period in global warming propaganda is 1950 on. You might expect them all to be around 1950 to 2000 or so wouldn’t you? Well, if you believe in global warming you might. But if you haven’t been taken in, you might not.
Well, only two months (July and August) were from the modern era. October was close, but 1912 to 1971 doesn’t fit the AGW cult criteria.
Eight of the months started the trend in the 1600s. One in the 1700s.
So much for CO2 as the cause of “unprecedented warming”. The warming was for the most part very precedented.

Antarctic Sea Ice Extent data has been unavailable for a few days. I emailed NSIDC and today they replied and said:
“Occasional short-term delays and data outages do occur and are usually resolved in a few days. We are currently experiencing such a short-term delay and we will get the issue resolved as quickly as possible.”
Commenter Gary also posted a link to this page that says:
“October 25, 2013: Daily updates to the graph and image are temporarily suspended due to technical difficulties with the data provider.”
Yesterday I did post about HADCET data by month showing how some of the months have a 350 year flat trend.
Today I thought I would look at the top 18 year warming trends at anytime in the 350 year history of HADCET. Why 18 years? Well, 1980 to 1998 was 18 years.
You might expect them all to be around 1980 to 1998 wouldn’t you? Well, if believe in global warming you might. But if you haven’t been taken in, you might not.
Only one recent month made it in the top. February 1983 to 2000. 2.53C per decade. Helped by the 5th coldest February in 1986 and the 3rd warmest February in 1998. That was an 8C rise.
But the next closest was January 1959 to 1976. And five of the trends start in the 1600s! One in the 1700s. And four in the 1800s.
There is nothing unusual about the warm in the 1980s to 1990s.

I was looking at the HADCET data by month out of curiousity and I noticed that the month of June had a pretty flat trend for a long, long time.
So I thought to myself, how far can I go back with HADCET and get a flat or just slightly flat trend for individual months?
The graph below (click for full size) has a graph for each month. The months are grouped by season. And the data for each month is the the furthest back you can go with a trend of 0C/decade or lower.
The grand champion is June. The trend is 0C/decade from 1663 to 2013.
Wow. Not much of a “Global Warming Signal” in a 350 year flat trend is there?
2nd longest is February with 0C/Decade trend from 1846 to 2013.
3rd longest is December with a -0.003C/Decade trend from 1907 to 2012.
4th is July from 1981. 5th is March from 1986. 6th and 7th is January and August from 1987. May from 1988. October and November from 1994, September from 1995, And April from 2001,
I always wonder why CO2 is such a selective month.
Antarctic Sea Ice Area came within 85,200 sq km short of an all time record. Sea Ice Area reached 16.14718 million sq km on day 282. This was the 7th highest of all time.
I normally do Sea Ice Extent, but Cryosphere uses Sea Ice Area.
Sea Ice Area had lagged Extent for most of the peak, but suddenly advanced after the normal maximum was reached. The maximum for 2013 was reached on day 282 which is 19 days later than the 2007 record.
2007 holds the record for most Sea Ice Area at 16.23238 million sq km.
Winter temperatures in the Northern Hemisphere are dropping as much as 2.5C / decade over the last 7 years.
Yesterday my post was a look at the northern hemisphere by month over the last 7 years.
Today I am looking at the same time frame, but I am using the gridded HADCRUT4 data for Dec/Jan/Feb only. You will have to click on the image to get the full effect.
There are 7 latitude bands with yellow highlighting. The trend in those is from -.44C/decade to -2.49C/decade. And note the green 0 line. 0 is the 1961-1990 average, Anywhere the graph or trend crosses the green line it is colder than the 1961-1990 average. It was pretty cold in the 60s and 70s.
I wish I didn’t live in the 50th parallel.
Do you live in the Northern Hemisphere.? Did anyone tell you that in the midst of record CO2 levels HADCRUT4 shows massively dropping winter temperatures?
At the bottom of this post is a graph of HADCRUT4 Northern Hemisphere only temperatures for each month for the last 7 years.
Did you know December was cooling at -.9C per decade? By 2100 December could be 8C colder?
Did you know January was cooling at -.73C per decade?
Did you know March was cooling at -.56C per decade?
Did you know February was cooling at -.19C per decade?
Did you know November was cooling at -.2C per decade?
Did you know October was cooling at -.17C per decade?
Did you know April was cooling at -.17C per decade?
I’m glad I have a wood stove.
Over the last 10 years HADCRUT4 has had a slightly negative trend. But the months each have their own trend.
September to April have been cooling, while May – August have been warning, All 12 months with trends are below.
I wonder why CO2 has forsaken the winter months?
The interesting thing is this matches the AMO as you can see in the post I did in January. (I would do a new post but the US shutdown has shutdown the page I got the AMO data from).
When the AMO finishes going negative this will be very bad news for the CO2/Warmist Cult.. And even worse news for the world’s agriculture.
Right now, Dec/Jan/Feb are cooling at -0.17C/decade to -0.25C/decade. Brr. Germany is already off to the coldest start of winter in 200 years.
NASA is telling lies about the southeast USA. They claim that sulphates were causing the Southeast to stay cooler and masking AGW. For some reason they use the term “warming hole”.
Read about it here.
How do they explain that it was warmer in the southeast in the 20s and 30s than now?
Here is the big lie that jumped out at me.
“As a response to the declining sulfate levels, Leibensperger’s modeling shows temperatures over the central and eastern United States have increased by 0.3°Celsius between 1980 and 2010.”
The trend from 1980 to 2010 (using NASA’s own data) is indeed .2C per decade.
But the trend from 1990 to 2010 is in fact negative. It is -.2C per decade.
And the trend from 1895 to 2010 is FLAT!
