Pre-1970s ‘Global’ Sea Surface Temp Measurements Are No More Reliable Or Accurate Than Guessing

The accuracy of the long-term global instrumental temperature record – especially the data obtained before the 1970s – wholly rests on the assumption that sailors obtained precisely reliable temperature measurements as they pulled wooden or canvas buckets out of the water from ships at random depths, locations, and times of day. They didn’t.

It has long been known that pulling a bucket out of the water from a ship is rooted in serious error, rendering the sea surface temperature (SST) data obtained nearly useless. Ashford (1948) summarized some of the more salient reliability problems with this method of measurement.

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address

  • I was a "conspiracy theorist". Now I'm just right.

If the data prior to 1970 is deemed inaccurate, than the segment of sea surface temperatures represents only 52 years. That is such a ridiculously small segment of the total data as to be negligible.

(Since the dawn of the Paleozoic, 0.0000086%, and since humans (roughly 4 million years) 0.0013% of the data, 0.43% since the last ice age (12,000 years ago)).

For all practical purposes, a mere point on a line, and not enough to set any meaningful trends, hardly reflective of a significant portion of the total data set.

Seventeen Techniques for Truth Suppression

Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.
