Record high global temperature in June a lie

Drawing on NOAA data, it is asserted below that we did have a record high global temperature in June.  But the "record" temperature exceeded the previous high by only one twentieth of one degree, a figure that would be non-trivial only if it were repeated frequently.   More importantly, it is well outside the accuracy inherent in the data.  Temperature measurement is very spotty worldwide with large areas such as China, Russia and Africa having very few data sources. So a great deal of the "data" used to calculate world temperature is in fact "interpolations", in plain language guesses.  So one immidiately suspects that the guesses were simply more expansive in June.

And the U.S. temperature data strongly supports that suspicion.  The USA by far has the best temperature record.  The measurements are not perfect.  They are affected by siting problems in many cases but there are so many meassuring stations that interpolations are rarely needed.  So what does out best source of uninterpolated data show?  You can see it on the map below.  The USA was mostly one big COOL spot!  QED, as they used to say.  The global data is fudged

A minor source of amusement is that the NOAA report that formed the basis for the article below tabulates national temperatures for a number of nations, including such places as Latvia,  but does NOT give U.S. average temperatures!  I wonder why?

Last month was a scorcher for global temperatures with warmth over land and sea breaking records for June while sea-surface temperatures posted their largest departure from long-term averages for any month.

Combined average temperatures over land and sea were 0.72 degrees above the 20th century average of 15.5 degrees, making it the hottest June and adding to the record May and equal record April, according to the US National Oceanic and Atmospheric Administration (NOAA).

More striking for climatologists, though, were the sea-surface temperatures. These came in 0.64 degrees above the 20th century average of 16.4 degrees – the first time any month had exceeded the long-run norm by more than 0.6 degrees.

Parts of all major ocean basins notched their warmest June, with almost all the Indian Ocean and regions off south-eastern Australia the hottest on record.

An El Nino event remains about a 70 per cent chance of forming during the northern summer, which could see more records tumble. The weather pattern sees the central and eastern equatorial Pacific Ocean becoming relatively warm compared with western regions, and typically brings hotter, drier than usual conditions to south-east Asia and Australia.

Climate scientists say man-made emissions of greenhouse gases are trapping more solar heat and leading to the global warming that increasing the likelihood that hot rather than cold records will be broken.

The first half of the year tied 2002 as the third-warmest on record for land and sea-surface temperatures, NOAA said.
