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.
