Extreme Weather in 1759

A diary recording Bath’s weather, written by a clergyman about 250 years ago, has been found by archivists.


The parchment notebook belonged to Reverend Duel Taylor whose tiny writing recorded the city’s weather every day for six years between 1756 and 1761.


An entry in December 1759 shows extreme weather was not unusual with the the river “frozen so hard” people had to “walk across it for three days past”.


It was found among papers of Bath’s town clerks.



The Central England Temperature for December 1759 was 2.5C, about -2.1C below the 1961-1990 average.

WOW! – How Many Fabrications, Misrepresentations, etc., Can One Blogger Roll into One Blog Post?

Originally posted on Bob Tisdale - Climate Observations:

I always find Sou’s (a.k.a. Miriam O’Brien) posts at HotWhopper entertaining.   She normally is only capable of the Monty Python contradiction approach to argument.  When you read her posts in a Monty Python-light, they are very funny. Try it.  But in her recent post James Risbey and co: Another perspective on surface temperature observations and climate models Miriam has risen to new heights of misinformation.   That post was her “rebuttal” to my post Lewandowsky and Oreskes Are Co-Authors of a Paper about ENSO, Climate Models and Sea Surface Temperature Trends (Go Figure!).  It didn’t take long to understand what she had done.  She couldn’t counter my primary arguments (and if you’re wondering what they were, read the closing of my post), so Miriam just made stuff up.  I started to count the number of blatantly obvious fabrications, untruths, falsehoods, misrepresentations, etc., but then soon realized it would be better…

Sea Ice News Volume 5 Number 4 – Are polar satellite sea ice sensors going wonky?

I have been a bit worried about the deep deep dive in Antarctica Sea Ice Extent.

It appears to be a processing or sensor error. As of today the NSIDC data confirms it. (see image below)

In a deja vu all over again moment, I find that it isn’t just the Antarctic with wonky readings.

Rain totals for 19th July 2014

Originally posted on Met Office News Blog:

As forecast there were severe thunderstorms across the UK on the 19th July bringing heavy rain and gusty winds. See the tables below for the largest rain totals across the UK.  Gloucestershire recorded the highest rainfall with 66mm between 6am and 6pm yesterday, the counties monthly average rainfall is 60.6mm.

The Heat-health watch put in place in parts of southern and eastern England in conjunction with Public Health England has now been downgraded. Temperatures in parts of the area covered topped 28C during 19 July, see table below.

Today, 20 July, temperatures are expected to reach low to mid 20’s across central, south and south east of England, with London seeing around 27C.  Northern England will reach mid to high teens and Scotland and Northern Ireland mid to low teens.

More thundery downpours are expected to develop today over some eastern and central parts of the UK.  A yellow, be…

TOBS Update: Something Seriously Wrong At USHCN

Originally posted on Real Science:

Last week I showed some graphs like the ones below, which demonstrate that the TOBS (time of observation bias) adjustment is bogus. Stations which took their readings during the morning on July 15, 1936 are actually cooling slightly relative to the July 15, 1936 afternoon stations. This behavior is the opposite of what TOBS was created to correct.

So this morning I tried the same experiment on the raw monthly USHCN data using the identical set of stations as was used in the daily analysis. In this case, something very unexpected appeared. The morning stations are warming much faster than the afternoon stations, which is what TOBS theory predicts.

ScreenHunter_1158 Jul. 20 09.26

This discrepancy makes no sense, because I am using the identical set of stations for both the monthly and daily data. The monthly data is supposed to be the average of the daily data.

So the next obvious experiment was to compare the monthly data for…

Sea Ice Update July 19 2014 – Antarctica/Arctica Continues to Surprise

Originally posted on sunshine hours:

Antarctica is only 50,000 sq km from the record for the day. And the Arctic is melting slowly.

A quick update for sea ice extent for day 200 of 2014

  • Global Sea Ice Extent is -354,000 sq km below the 1981-2010 mean. That is ranked 23 for the day.
  • Antarctic Sea Ice Extent is 973,000 sq km above the 1981-2010 mean. That is ranked 2 for the day.
  • Arctic Sea Ice Extent is -1,328,000 sq km below the 1981-2010 mean. That is ranked 31 for the day.

This mornings thunderstorms…


Some impressive totals. It was quite a nice day in the middle of the country yesterday – except for the humidity!

Just a quick screen shot of the estimated rainfall accumulations derived from the Met Office 15 minute weather radar images for the period 0000 to 0930 UTC on Saturday July 14, 2014. It looks like the highest accumulations run in a line south-north, extending from the Dorset coast and through the Bristol area. It looks like accumulations topped out at around 50 mm, all though they are some isolated violet-coloured pixels that indicating totals in excess of that which is quite impressive in only just over 9 hours.
