Latest UAH & RSS Numbers

April 8, 2013

By Paul Homewood

 

A quick look at the satellite numbers, while we wait for the others.

 

Both UAH and RSS are virtually unchanged. UAH is exactly the same at 0.18C, and RSS is up from 0.19 to 0.20C.

Both are around or below the level they were in Nov/Dec.

 

I thought we’d have a look at longer term trends today though. Using HADCRUT4 numbers, I have plotted the monthly numbers since 1979, with a 10-year running average.

Within the last decade, temperatures have definitely flatlined. For instance, the latest 12-month average is 0.47C, and this compares with a figure of 0.49C for 2002.

But, intriguingly, the longer term, 10-year average also stopped rising at the end of 2010, and has actually started to fall back. This is not clear on the scale of the above graph, but zooming in below illustrates it well.

The amounts may be small, but the evidence is clear – the world has been getting colder in the last few years. This is not down to a single year’s figures, nor ENSO variations, as the 10 year span will even out such fluctuations.

 

Perhaps we really should be worrying about global cooling again.
