France’s new ‘hottest recorded temperature ever’ is in query – guess the place it was measured?

Ian Duncan writes on Fb:

‘France has its hottest recorded temperature ever’.

New file – 45.9C on June 28th, beating the previous absolute file of 44.1C in 2003.

However they don’t point out that the place it was recorded was subsequent to a concrete drain, and a metal chain mesh fence near a bitumen (asphalt) freeway.

A lot for under utilizing appropriately positioned devices in a Stevenson Display screen in a open house away from unnatural warmth supply.

You’ll be able to see the station right here:

Right here is the enjoyable half – it may be the “greenhouse impact” /sarc

Significantly although, who is aware of what impact these greenhouses may need had on the excessive temperature? What we do know is that greenhouses accumulate warmth and lift the temperature. Relying on wind course that day, they might have vented waste warmth within the course of the thermometer shelter. The identical may very well be true for the asphalt freeway.

As for the warmth wave itself, Dr. Roy W. Spencer provides:

When Saharan air reaches Europe, it’s going to be scorching. Relating to record-high measurements, it’s reputable to ask concerning the placement of temperature sensors, in addition to the size of temperature data.

For a file size of, say, 100+ years and NO long run warming pattern, it’s nonetheless anticipated from random climate variations that new file excessive temperatures shall be recorded once in a while.

The current file excessive in Miami, FL was made in the course of an unlimited concrete jungle that didn’t exist 100 years in the past, and now averages 10 deg. F hotter at evening than rural environment.

One different factor to contemplate – Stevenson screens which are simply accessible like which are liable to biases (or forcings, if you’ll) that “actual climatologists” don’t normally think about – like automobiles being parked subsequent to them.

Bear in mind this fiasco in Scotland a few years in the past? An ice-cream truck with mills continually operating was the reason for a “man-made climatological occasion”.

So is the brand new French absolute all time excessive temperature file legitimate? I’m surmising it’s not. There’s simply too many influences to contemplate.

Definitely, the measurement surroundings there may be far totally different than that of 100 years in the past. And, who is aware of if anyone parked a automobile subsequent to that French station on June 28th? Perhaps a lunch wagon/meals truck frequents there to cater to the nursery staff.
