1.5C of Warming in 27 years – Mar 1917 to Jan 1944 – Northern Hemisphere

1.5C of Warming in 27 years – Mar 1917 to Jan 1944 – Northern Hemisphere (data here)

Jan 1944 Northern Hemisphere Anomaly = 0.656

Jan 2013 Northern Hemisphere Anomaly = 0.545

It was .111C warmer in Jan 1944 than Jan 2013 in the Northern Hemisphere.

Why does the AGW cult ignore this?

HADCRUT4 – The Greatest 30 Year Temperature Rises

In a previous post I noted the largest one month rise for HADCRUT4 was in 1862/1863. AGW cult members are always talking about climate being 30 years.

So lets look at the greatest temperature rise in HADCRUT4 where the period is anywhere from 1 month to 360 months (30 years).

The winner at 1.296C was Jan 1864 to Feb 1878. Here are the top 25.

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.

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.

HADCRUT4 1930 to 1949 by Month – Dangerous pre-CO2 Global Warming

HADCRUT4 1930 to 1949 by Month.

Normally you see this part of the graph with 2 or 3 red ticks because it is done annually.

Keep in mind the highest red tick is an anomaly of 0.355C for August 1945. The anomaly for August 2012 was 0.532C. Which is only 0.177C warmer. (Corrected)
