Read excerpt
This afternoon, at 4pm BST, founding members over in John Dee’s Climate Normal are getting a sneak preview of a dataset I’m building for the study of the urban heat island effect. At 3am BST this morning I realised the same dataset could be used to explore the role of urbanisation in rise of modern diseases.Sure, we have lifestyle, nutrition, education, and medical advances to consider (and many more besides), but I sat wondering if aspects of urban development might also correlate with the rise

In part 2 of this series I offered up four slides revealing the mean weekly observed registered death count for England & Wales for the period 2017 w1 – 2026 w32.

In part 1 I promised 8 slides following a trip to the shops to grab a bag of Grumpy Mule. With that all done, and a decent cup of coffee on the brew, then I suspect it is best to start out with registered deaths by season first, then have a look at crude mortality by season later on. My reluctance to dive into crude mortality straight away is that I don’t, as yet, trust the rusty mid-year population estimates issued by the ONS that I have sitting on my HDD.

Influenza is not revealing its secrets that easily, and so my interest has faded like our lettuces in the recent heatwave. And it was this heatwave that got me cooking in the kitchen over in John Dee’s Climate Normal, starting with this article.
