HADCRUT Cool The Past Yet Again

|
Paul Homewood, Not A Lot Of People Know That

HadCrut have just released their latest version 4.4, and guess what? Yes, the past has been cooled again!

This is is how things have changed since version 4.3.

As usual we see temperatures earlier in the record being reduced, but more noticeably temperatures have been progressively increased since the 1990’s. The amounts are only small, and the usual defence from the Met Office is that the changes make little difference to long term trends.

However, we find that similar adjustments have now been made since the original version 4.0 was released in 2012. Note that the anomaly for 2010, (the last year that appeared on version 4.0), has increased by 0.004C on the latest revision, but by 0.029C over the four revisions since version 4.0.

The gradual changes to the temperature record can be seen with what they have done with 2010.
