Collecting valid data is hard. Paul Homewood has highlighted a Met Office report for 2014, produced it seems September 2015. If that is true, no rush, get it right.
— From State of the UK climate 2014
Oh yes definitely more severe weather..
Snag, this is Met Office data against Met Office data.
Figure 2, same using normalised data from another work (modified to use the shorter data). Figure 1 acts as an honesty check, same, same linear trend. (the author knows it ought to work, readers won’t)
A 2 year running standard deviation plots the change in variation.
See how CO2 kicked in January to February 1996, clever lot foreseeing that was going to happen all of a sudden. 🙂
What is going on?
The author was very active in embedded systems and instrumentation into industry more than 35 years ago.
Sixteen years later… “Daily automated values used after 1996.”, see link below. This is the reason for so many datasets changing late 1980s onwards. Sure it’s man made. Bally all to do with actual change.
Is that the reason for the change fig 1 or 2? It’s a real candidate. Other evidence points to station network change, a documented change point.
