Recently, the U.K. Met Office announced a revision to the Hadley Center historical analysis of sea surface temperatures (SST), suggesting that the oceans have warmed about 0.1 degree Celsius more than previously thought. The need for revision arises from the long-recognized problem that in the past sea surface temperatures were measured using a variety of error-prone methods such as using open buckets, lamb's wool–wrapped thermometers, and canvas bags. It was not until the 1990s that oceanographers developed a network of consistent and reliable measurement buoys.
[...] But that's where the good news ends. Because the oceans cover three fifths of the globe, this correction implies that previous estimates of overall global warming have been too low. Moreover it was reported recently that in the one place where it was carefully measured, the underwater melting that is driving disintegration of ice sheets and glaciers is occurring far faster than predicted by theory—as much as two orders of magnitude faster—throwing current model projections of sea level rise further in doubt.

No, you dont seem to understand..
Old people are stupid. They could never read a thermometer correctly.
In fact, the further you go back, the more stupid they were, and they got the reading more and more wrong.
The interesting bit is that they always got the reading wrong in one direction - they always read a higher temperature.
So, the only way to fix this is to assume that since older people are more stupid, and they always over-read.. An adjustment MUST be required, and the real temperature was colder the further back you go.
How do they prove this? Models of course! If it wasnt true, then their models wouldnt show what they do.. so it MUST be true.
And if the models dont match next years measurements? More adjustments! Not to the models, but to the historical data - thats the ticket!

Must not feed the trolls...
Old people may not be as stupid as you appear but technology is always
evolving and getting more accurate. In the old days we all used
analogue weight scales which are accurate to plus or minus 1 lb, now
we use digital scales accurate to .01 pound, and my cheap digital
calipers are (reasonably) good to .001 mm. It is entirely possible
that earlier measuring techniques were .01C high, that's the
definition of bias in measuring, and happens all the time. In, fact
it's not even hard to check the two tools side by side.
Meanwhile we have record heat waves with temperature increasing on the
order of .05 C EVERY summer, so the whole point about .01 C is moot.

The average U.K. summer temperature between 2008-2017 has risen by 0.7ºC

Wow, impressive, a double-cherry-pick!
1: Heatwaves can decrease while the average increases.

The post I was responding to said
My link regarding heatwaves was on-topic and not a cherry-pick at all. Their post said nothing about region. There's a good chance they meant the US. Anyway, a lot of US people are unaware of the long-term heat wave trend, so I posted the link for them to check it out.

It may have increased since the 1960s and 1980s, but before that, in the 1930s, heatwaves were even stronger!

Oh FFS, having spent a hell of a lot of time in chemical labs weighing all sorts of stuff to fractions of grammes using analogue mechanical balance scales, that statement is just so full of shit I don't know where to start, does the name Sartorius (the name I'm most familiar with) mean anything to you?, if not, google them..and while you're doing that, find the Wikipedia page on Weighing scales and have a read.
And, how would you know? Ever checked them out against a certified thickness standard ?
There is a world of difference in the real vs stated accuracies of cheapo calipers and those of their more expensive bretheren (I've always liked those made by Mitutoyo, can't afford them for home abuse though)

Oh, please - they were weighing grams in the 17th century. Molar weights and masses were understood by a guy who died in 1910 . . .

Let us note that small measurements like the gram were discovered/invented in France in the 17th century, but that doesn't necessarily mean that the Egyptians, Babylonians, Chinese, or some forgotten culture didn't have something like it first.
