Where does Lord Stern get his facts?

Recommended Posts

Hi
 
I read an article in the Guardian today and it has me puzzled. Lord Stern states in the third paragraph of that article that climate change has arrived and is now happening. This may be correct , but what he says next to support his claim is not:
 
“Four of the five wettest years recorded in the UK have occurred from the year 2000 onwardâ€
“Over that same period, we have also had the seven warmest yearsâ€
 
With regard to the rainfall in the UK I use as my evidence the UKP dataset maintained by the UKMO and which dates back to 1766, and is in fact the oldest instrumental record of its kind in the world.
 
<Image:England Wales Annual Rainfall (1766-2013)>
 
You will see from the graph of the England Wales Precipitation series that only two and not five of the years since 2000 are in the top five wettest years (2000 & 2012), the next 21st century year 2002 appears at number 11. So instead of four out of five its 2 out of 5, or to be fair its 2 out of 10! What a whopper.
 
The second one is worded ambiguously in my opinion – what I think he’s trying to say is that 7 of the warmest years have occurred since 2000. As far as I can tell Lord Stern is still talking about the ‘UK’, as he was in the sentence before with regard to rainfall. So he is talking about UK temperatures and not global temperatures, and therefore I use as my evidence here the Central England Temperature series, which is also maintained by the UKMO and dates back in its monthly form to 1659.

As you can see in the rank tabulated list above, of the top ‘seven warmest years’, only three  of the top seven occurred in this century 2006 (#1), 2011 (#2) and 2002 (#5), so why did Lord Stern say that ‘we had the seven warmest years’ when we only had three?
 
I’m obviously missing something or other here, and I’m sure someone will explain what Lord Stern did mean in his article and point out what evidence he is using to support his claims about the five wettest and seven warmest years in the UK. Believe it or not, I’m a climate change agnostic, but I do have a passion for weather statistics, and hate it when someone is being more than a little misleading in using them!

It seems to be best not to confuse them with facts.You just have to believe the propaganda, because it comes from an 'expert'.

Reminds me of Sheffield in 2007. Never had so much rain in a day before. We we had and if I had the paper records going back to 1955 to hand I would have probably found it was a fairly common occurrence.  What they did miss was how wet the two weeks before were which coupled with bad maintenance bad planning led too bad flooding.
