HADCRUT4 February 2014 – Global Warming?

HadCRUT4 is a gridded dataset of global historical surface temperature anomalies relative to a 1961-1990 reference period.


HADCRUT4 Feb 1878 0.403C

HADCRUT4 Feb 2014 0.299C




Global Warming?





What Would 2C of Warming By 2036 Look Like?

Michael Mann: “our planet would cross the dangerous warming threshold of two degrees C in 2036, only 22 years from now. ” (h/t Jeff Id)

Using HADCRUT4 and WoodForTrees I graphed the data from 1850 t0 2014, and then added in 2C of warming by 2036.

What a joke.

Update: The biggest rise over 22 years was March 1976 to February 1998 = 1.193C. The 4th biggest was March 1856 to February 1878 = 0.913C.


40 Years of Rising CO2 compared to Temperature

40 Years of Rising CO2 … 1940 to 1979. Officially CO2 measurements only started in the 50s, but I think one can extrapolate backwards.

CO2 didn’t have much effect. The Temperature trend over those 40 years was -0.026C per decade. About -0.1C for the 40 years.

Lets take a look at the same graph without the CO2 part.

Northern Hemisphere Winter Doom By Latitude Band

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.

HADCRUT4 Northern Hemisphere Winter Doom

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.

HADCRUT4 10 Years By Month = AMO

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.
