Thanks. Very interesting. I think a degree of hyperbole may have crept
in here and there, though. For example:

"By 1816, after months of global cooling, the coldest instrumentally
recorded year in Britain began."

In fact the mean CET for that year was 7.87, admittedly very chilly. But
just two years earlier, in 1814, the CET was 7.75, and that was before
the Tambora eruption had occurred. Comfortably the coldest annual CET
was 6.84 back in 1740. OK, Central England and Britain aren't
synonomous, but I don't think the writer can have any data to back his
claim.

Well I never knew that! The Battle of Waterloo was won by Tambora and not Wellington :-)

Cheers, Alastair.

You Scott's always favoured the French even the Normans, but that didn't work out quite the way it was intended either.

The cold CET in 1814 was probably due, at least in part, to the massive
eruption of 1808 which seems to have had a greater effect on global
temperatures than did Tambora.

Anyone care to comment on the 1703 storm meteorology noted by Defoe in
his book, here
https://ebooks.adelaide.edu.au/d/def.../complete.html
The barometer was not that dramatically low a minimum at 964mB at
whatever height Upminster is.
The Toricelli barometer had been around for only a few
decades but even so Vernier scaled models were being used in 1703,
Halley presumably Fellow of the RS, and of comet fame, .

I've added decimal points to that transcript, (integre inches only
recorded passing through that transition, and fractional hours not minutes)
(28.47 in of Hg = 964.0 mBar, presumably not sea-level adjusted value)
