John Kennedy said to me
‘Even if SST measurements were subject to random errors of even 10 degrees, which they are not, then we would still be able to make a reasonable estimate of global annual average SST because individual random errors tend to cancel in the aggregate.’
Random suggests very infrequently and haphazard. You cite 10 degrees as still being within the range that would enable you to retrieve a reasonable global average.
What % of the record base would be able to exhibit these ‘random’ errors yet still enable you to overcome this sort of degree of inaccuracy?
Half a percent? 20%?
. I don’t want to put words in your mouth so perhaps you can tell me.
