Steve McIntyre famously determined that Michael Mann was using a paleo proxy data series upside down in a paper. Mann’s response (though not directly because he doesn’t speak with mere people with questions) was “it doesn’t matter”.
I wonder what CRU will have to say about this one that has been discovered? It’s bigger than just a single point on Earth.
Bishop Hill notes:
Reader John McLean emails with details of some surprising finds he has made in the Hadley Centre’s sea-surface temperature record, HadSST. John is wondering whether others might like to take a look and confirm what he is seeing. Here’s what he has found:

UPDATE: 3/26 Josh adds:
A hilarious possibility but one which Zeke has already said has been fixed or was wrong. Well, that’s a relief – these things do tend to happen in Climate Science.

The CRU updated its files on March 30. Now, just after the table and about 30% down the page, we find …
“Correction issued 30 March 2016. The HadSST3 NH and SH files have been replaced. The temperature anomalies were correct but the values for the percent coverage of the hemispheres were previously incorrect. The global-mean file was correct, as were all the HadCRUT4 and CRUTEM4 files. If you downloaded the HadSST3 NH or SH files before 30 March 2016, please download them again.”
No correction yet from Hadley Centre, team leader John Kennedy is out of the office until April 6th.
FYI, a post at Bishop Hill by Tim Osborn might interest, has given credit to you.

The files on the CRU website containing the NH and SH averages of HadSST3 contained the correct temperature anomalies but the values for the percent coverage of the hemispheres were incorrect (the NH and SH values were swapped). They have been replaced with corrected files today. Thanks to John McLean for noticing that there was a problem with these files.
The global-mean file was correct, as were the HadCRUT4 and CRUTEM4 files. If you downloaded the HadSST3 NH or SH files before 30 March 2016, please download them again.

Oops, John and Mick are a good day ahead of me.
