But hey but what do I know. Nothing

You've realised!


His knowledge is actually negative.
He sets out to deliberately mislead and misinform.

Well it's either a badly presented graph or it's the longest continous
drop of the running mean since 1860!

It is a 10 year running mean and as such the values from 2003 onwards
are the averages of 9,8,...1 readings and so are dominated by the last
few years one of which was negative. It is an artefact of the smoothing!

The long term sliding 10 year mean will correct itself when the full
data are available, but the smoothed graph has a misleading artefact at
the end of its range.

I know that. But surely the rest of the graph is as well. It is still
the largest consecutive drop in rate of coolong since 1860 in the CET. I
wasn't drawing any great conclusions from that but it is what is and
should be recognised as such.
