One hundredth of one degree in seven years, all due to supposedly naughty humans? Hilarious. An ex-boss of mine used to call such tiny variations ‘spurious accuracy’. What’s the margin of error?

The world’s oceans set a new temperature record this week, raising concerns about knock-on effects on the planet’s climate, marine life and coastal communities, says AFP (via Euractiv).
The temperature of the oceans’ surface rose to 20.96 degrees Celsius on 30 July, according to European Union climate observatory data.
The previous record was 20.95C in March 2016, a spokeswoman for the EU’s Copernicus Climate Change Service told AFP on Friday.
The samples tested excluded polar regions.
The US National Oceanic and Atmospheric Administration (NOAA), which uses a different database, has also recorded a similar trend in recent months.
It said the average sea surface temperature record was reached on April 4 this year at 21.06C, overtaking the previous high of 21.01C in March 2016. On 1 August, average temperatures were at 21.03C, it said.
Oceans have absorbed 90% of the excess heat produced by human activity since the dawn of the industrial age, according to scientists.
This excess heat continues to accumulate as greenhouse gases — mainly from burning oil, gas and coal — build up in the Earth’s atmosphere.
Globally, the average ocean temperature has been topping seasonal heat records on a regular basis since April.
‘Immediate threat’
“The ocean heatwave is an immediate threat to some marine life,” said Piers Forster of the International Centre for Climate at Britain’s University of Leeds.
“We are already seeing coral bleaching in Florida as a direct result and I expect more impacts will surface.”
The overheating of the oceans is predicted to have other effects on marine plant and animal life too, including on the migration of certain species and the spread of invasive species.
This could threaten fish stocks and thus undermine food security in certain parts of the globe.
Warmer oceans are also less capable of absorbing carbon dioxide (CO2), reinforcing the vicious cycle of global warming. [Talkshop comment – vicious…tremble now!]
And higher temperatures are likely to come, since the El Nino phenomenon, which tends to warm waters up, has only just begun.
Scientists expect the worst effects of the current El Nino to be felt at the end of 2023 and continue into subsequent years.

Vicious circle: noun Logic ‘A fallacy in reasoning in which the premise is used to prove the conclusion, and the conclusion used to prove the premise.’ – Wordnik.
(It does offer two other definitions but that’s the ‘logic’ one).

“What’s the margin of error?”
Indeed. Even with sat measurements, what’s the cal trail to NIST?
Dear Oldbrew,
We are in an interglacial period of the Quaternary Ice Age, but in an Ice Age nonetheless are we not? Meaning that the Planetary Temperature is below its historic average.
I think the Alarmists should tell us how they intend to stop the planet recovering to its average temperature since according to them we would all be dead if it did, so how are they going to save us and how did we get here in the first place according to that and while they are about it perhaps they could explain what they mean by “Unprecedentedly hot” when we are in an Ice Age.
The first question anyone should be asking – ‘how did they manage to get that hundredth of a degree accuracy in the oceans’ and the second question should be – ‘where did they measure it.’
In a real world situation a one degree reading would be optimistic so I can only conclude they are using computer games to get this result even if they are taking an average of several readings common sense should tell them that figure is so stupid to be laughable.
It’s simply non-science. It’s an average but at such high resolution it’s meaningless – and is meaningless at any resolution anyway. The idea that coral gets bleached by a global average is so bizarre as to be quite funny. They don’t seem to understand that most or even all coral could be at temperatures below their record average. This is truly pathetic, truly dreadful stuff.
The temperature of the oceans’ surface rose to 20.96 degrees Celsius
Not quite ‘boiling’ then 😂
how do they measure SST globally simultaneously, and accurate to 3 decimal places
and why did they leave out the Arctic and Antarctic oceans? All this ‘sky is falling’ BS about temperatures is nothing more than panic drivers to convince the NPC’s and mouth breathers that we need to kill off two thirds of the world population and move to a Middle Ages feudal system of death, disease, and starvation.
Uh… NO THANKS!
StPC – ‘why did they leave out the Arctic and Antarctic oceans?’
Too little data to be of any use? Or – likely to make the final figure look boring 🤔
Heh, more Playstation science!
I can tell!
Last Year’s Nobel Physics Laureate Signs World Climate Declaration Stating ‘There is No Climate Emergency’
BY CHRIS MORRISON 15 AUGUST 2023
For his part, Clauser told a recent group of young Korean scientists that they must follow the scientific method based on good observations and experiments. Good observations always overrule purely speculative theory. Referring to climate science, he noted the world was “literally awash, saturated, with pseudoscience, with bad science, with scientific misinformation and disinformation”. At a time when the unhinged head of the United Nations Antonio Guterres was claiming the world had entered an era of “global boiling”, he gave his opinion that the UN-funded IPCC “is one of the worst sources of dangerous misinformation”.

IPCC aided and abetted by the miserablist media, as many of them deserve to be called.
Bloke ==> The whole report, from AFP (a partner member of the climate crisis news cabal, Covering Climate Now) conflates Sea Surface Temperature (skin) with “overheating of the oceans” — Sea Surface Temperature (skin) is caused by more sun and less wind.
Environmental Protection Agency’s (EPA) Climate Regulations Based on a ‘Hoax
William Happer, professor emeritus in physics at Princeton University, and Richard Lindzen, professor emeritus of atmospheric science at Massachusetts Institute of Technology (MIT), argued that the claims used by the EPA to justify the new regulations are not based on scientific facts but rather political opinions and speculative models that have consistently proven to be wrong: https://rwmalonemd.substack.com/p/two-princeton-mit-scientists-say
The surf club where we go regularly measures the ocean temperature daily (the beach has life savers all year around). It is winter at present and the water temperature is 22C. In summer the water temperature is around 25C. The Great Barrier Reef (GBR) is further north and its average temperature is about 25C. (It rains most of the year but especially in summer). The GBR is teeming with life and is in the best condition since monitoring started. However, there are reefs closer to the equator which also teem with life where the water temperature gets up to 30C. making a claim about average ocean temperatures is nonsense. Surface temperatures change all the time within several degrees depending on sunshine, rain, winds, storms etc. It is impossible to measure an average at any specific time.
For all who question the .01 C temperature accuracy, just 2 words. “Adjustments Galore”. Went looking for accuracy and just what they are able to measure after a post back in 2014 and had a real awakening. Seems that overall measuring of ‘sea surface’ has problems. Original bucket & thermometer (no depth control), ship intake (well below surface and varied depth due to load +/-20 feet), buoys (seem to rock in the wave with depth resolution of a meter), then IR satellite (cannot get thru the clouds) to microwave (get thru the clouds, but not the rain & surface mist). Oh and did I mention one of the satellites was doing reasonable until they had to boost the altitude, then had problems with pitch, yaw and just had no idea the height it was flying.
The number of adjustments to correct is staggering. Includes (but not limited to); wind speed, rain, cloud amount/percent and cloud water vapor, daytime diurnal warming, high latitudes, aerosols, SSTs <10C, columnar water vapor, higher latitudes show a slight warm bias, seasonal cycle wind direction for SST retrieval, fast moving storms and fronts, wind direction error and instrument degradation.

Still their abstract reads –
Errors were identified in both the MW and IR SST data sets: (1) at low atmospheric water vapor a posthoc correction added to AMSR-E was incorrectly applied and (2) there is significant cloud contamination of nighttime MODIS retrievals at SST <10C. A correction is suggested for AMSR-E SSTs that will remove the vapor dependency. For MODIS, once the cloud contaminated data were excluded, errors were reduced but not eliminated. Biases were found to be 20.05C and 20.13C and standard deviations to be 0.48C and 0.58C for AMSR-E and MODIS, respectively. Using a three-way error analysis, individual standard deviations were determined to be 0.20C (in situ), 0.28C (AMSR-E), and 0.38C (MODIS).
So their reported deviations are 38 times as large as the record reading.
