Ocean Temperatures and Climate Hysteria: A Lesson in Perspective

by C. Rotter, Dec 20, 2024 in WUWT

For the past two years, headlines, policy statements, and social media feeds have been flooded with dire warnings about rising ocean temperatures. Every uptick in the graphs was treated as irrefutable proof of humanity’s march toward ecological collapse. The news cycle offered little room for nuance, and as usual, the loudest voices declared the end was nigh. But a recent tweet from Javier Viños, supported by a graph of global sea surface temperatures (SST), reminds us how quickly climate “emergencies” dissolve when confronted with even the faintest hint of natural variability.

New Study: Human Emissions ‘Irrelevant’ In Determining Changes In Atmospheric CO2 Since 1959

by K. Richard, Sept 2, 2027 in NoTricksZone

“The main factor governing the annual increase in atmospheric CO2 concentration is the SST [sea surface temperature] rather than human emissions.” – Ato, 2024

Another day, another new scientific paper has been published reporting efforts to curb anthropogenic CO2 emissions are “meaningless.”

In this study multiple linear regression analysis was performed comparing SST versus anthropogenic CO2 emissions as explanatory factors and the annual changes in atmospheric CO2 as the objective variable over the period 1959-2022.

The model using the SSTs (NASA, NOAA, UAH) best explained the annual CO2 change (regression coefficient B = 2.406, P = <0.0002), whereas human emissions were not shown to be an explanatory factor at all in annual CO2 changes (regression coefficient B = 0.0027, P = 0.863).

Most impressively, the predicted atmospheric CO2 concentration using the regression equation derived from 1960-2022 SSTs had an extremely high correlation coefficient of r = 0.9995.

Thus, not only is the paradigm that says humans drive atmospheric CO2 changes wrong, but “the theory that global warming and climate change are caused by human-emitted CO2 is also wrong.”

“SST has been the determinant of the annual changes in atmospheric CO2 concentrations and […] anthropogenic emissions have been irrelevant in this process, by head-to-head comparison.”

The Atlantic Is Cooling at a Mysteriously Fast Rate After Record Warmth

by P. Homewood, Aug 25, 2024 in NotaLotofPeopleKnowThat

For over a year, surface temperatures in the Atlantic Ocean hit new highs, but that trend has reversed at record speed over the past few months, and nobody knows why.

In June, temperatures in the Atlantic were 2 to 5 degrees Fahrenheit (1 to 3 degrees Celsius) hotter than normal in much of the ocean, with some areas getting as much as 9 degrees F (5 degrees C) warmer than average. Those temperatures weren’t a one-off, as the Atlantic had regularly seen record-breaking levels since March 2023. That year marked the fourth in a row that the world’s oceans set new heat records.

The hot water was partially a result of human-caused climate change, but it was also due to a particularly strong El Niño in 2023 and 2024. But that system appears to have passed, according to the National Oceanic and Atmospheric Administration.

NOAA data shows Atlantic sea surface temperatures have cooled at a surprising rate since May. Since June began, temperatures have been a degree or two Fahrenheit colder than normal for this time of year. That means El Niño will likely be replaced by its counterpart, La Niña, a weather system that allows cold water to rise to the surface of the Atlantic, some time between September and November. Both El Niño and La Niña are complex systems driven by trade winds, solar heating, and rainfall in the tropic regions, and can be difficult to predict. Still, the sudden shift in Atlantic temperatures has been puzzling, and nobody seems to know why it’s happened so quickly.

“We’ve gone through the list of possible mechanisms, and nothing checks the box so far,” Frans Philip Tuchen, a postdoctoral student at the University of Miami, told New Scientist.

.So they do not have a clue why the Atlantic has suddenly got colder, but they think they know that global warming made it hotter in the first place, even though there is no physical for the claim that a slightly warmer atmosphere can make any measurable difference to ocean temperatures!

They also get their knickers in a complete twist stating that El Ninos in the Pacific raise SSTs in the Atlantic!

Meteorologist: Why Claims Of The Ocean Having A ‘Record-Breaking Hot Streak’ Are Falsetts,

by A. Watts, June 15, in ClimateChangeDispatch

A recent ScienceNews (SN) article claims that ocean temperatures are out of control in a year-long record-breaking hot streak. This is false. [emphasis, links added]

Numerous ocean temperature datasets show no such record-breaking values. The source SN cited to support its claims was thoroughly discredited when it made similar “record-breaking” claims last year.

The entire claim of the article is based on one dataset, which is seen below in the SN article:

High sea surface temperature in North Atlantic

by Arctic News, Apr 22, 2023

SST World (60S-60N)

On April 20, 2023, sea surface temperatures (between 60°South and 60°North) had been at 21°C or higher for as many as 32 days. Such temperatures are unprecedented in the NOAA record that goes back to 1981.

 

On April 4, the sea surface temperature in 2023 (black line) was as much as 0.3°C higher than in 2022 (orange line) and we’re only just entering the upcoming El Niño.

 

SST North Atlantic

The situation is especially critical in the North Atlantic. Vast amounts of ocean heat in the North Atlantic are moving toward the Arctic, threatening to cause rapid melting of Arctic sea ice and thawing of permafrost. Last year, North Atlantic sea surface temperatures reached a record high of 24.9°C in early September and, as illustrated by the image below, the North Atlantic sea surface temperature on April 20 was as much as 0.5°C higher in 2023 (black) than in 2022 (orange).

As we’re moving into the upcoming El Niño, the Arctic Ocean can be expected to receive more and more heat over the next few years, i.e. more heat from direct sunlight, more heat from rivers, more heat from heatwaves and more ocean heat from the Atlantic Ocean and the Pacific Ocean.

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

by K. Richard, Sept 8, 2022 in NoTricksZone

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 initial temperature of the bucket is generally different from that of the sea.

• The water in the bucket may change its temperature before the reading is taken owing to the processes of heat exchange and evaporation.

• The initial temperature of the thermometer is generally different from that of the sample.

• The thermometer is liable to scale errors.

• Owing to thermal lag, the thermometer may take an appreciable time to indicate the true temperature of the sample.

• If the thermometer is removed from the bucket when taking the reading, it may no longer indicate the true water temperature.

• The temperature may be read incorrectly.

‘A Significant And Robust Cooling Trend’ In The Southern Ocean From 1982–2020 Defies Climate Models

by K. Richard, June 27, 2022 in NoTricksZone

A new study reports there has been a -0.3°C cooling in the Southern Ocean since 1982 per multiple observational data sets. The authors detail the “failure of CMIP5 models in simulating the observed SST cooling in the Southern Ocean.”

The Southern Ocean is today about 1-2°C colder than it has been for nearly all of the last 10,000 years (Shuttleworth et al., 2021, Civel-Mazens et al., 2021, Ghadi et al., 2020).

Global Sea Surface Temperature Records Suggest Only Modest Warming In The 20th And 21st Centuries

by Dieng et al., 2017 in NoTricksZone

According to Dieng et al., 2017, global sea surface temperatures (SST) cooled slightly (-0.006°C/decade) from 2003 to 2013. This reduced the overall 1950-2014 warming rate to 0.059°C per decade.

Sea and land surface temperatures, ocean heat content, Earth’s
energy imbalance and net radiative forcing over the recent years.

The NCAR/HadCRUT4 global SST record from buoys and ARGO floats also show only modest warming in the last 3 decades. The natural 2015-’16 Super El Nino event is mostly responsible for the overall increasing rate.

Major February global temperature drop reveals the real climate control knob

by J. Bastardi, March 7, 2021 in CFACT

By now all of you know my belief ( bias) that it’s the oceans, and more so the tropical oceans, that are the biggest control knob of the weather and climate. If you really wanted to make this a controlled classroom experiment (nature is not a classroom with easy controls)  then I venture to say that the real way to know man’s influence is to have SST’s return to where they were in the 1970s, give it a couple of years for the water vapor adjustment, ( and if I am right. co2 will adjust as warmer oceans outsource it, so the outsourcing to the air will decrease) and see the difference there. And there you may be able to make an irrefutable argument for man’s contribution, Unfortunately for those who will not look at anything else,  that is likely to be quite small, but on the other hand, unlike the warming we have had which is really in the coldest driest places and more so at their coldest driest time of the year, you would likely find the lions share of what warming would be where life thrives.. As small as that has been, less than .25C of the numbers we see all the time that tell us that at. a bit over 59 degrees the planet is overheating, it is liable to be even less detectable and certainly as or more adaptable than what we seemed to have adapted to nicely here.

But the fear of course is runaway warming which is interesting since it counters Le Chateliers,  which I never hear anyone bring up, most likely because it’s a simple explanation. And a simple explanation would impact a lot of things relying on a done deal, complex explanation that the public must accept because they could never understand.

Southeast Greenland Sea Surface Temperature 1° – 2°C Warmer In 1940 Than Today, New Study Shows

by P. Gosselin, Feb 14, 2021 in NoTricksZone

A team of Danish scientists led by David Wangner published a paper a year ago about the results of a Greenland sediment core from Skjoldungen Fjord, near the Thrym Glacier, which allowed sea surface temperatures to be reconstructed.

The core covers the past 200 years (1796–2013). The scientists find that the SST record compares well with other alkenone‐based reconstructions from SE‐Greenland and thus features regional shelf water variability.

Today some scientists like claiming the present is warmer than at any time in the past 1000 years and suggest the Greenland ice sheets are rapidly melting. But the results of the core reconstruction show that it was warmer in the past, some 80 years ago

Solar variability manifestations in weather and climate characteristics

by Zherebtsov G.A. et al., April 2019 in J.Atm&SolarTerrestrialPhysics

Abstract

We discuss the issues of primary importance to understand the nature of climate changes in the 20th century and main physical processes responsible for these changes and present a physical model for the solar activity (SA) effect on climate characteristics. A key concept of this model is the heliogeophysical disturbance effect on the Earth climate system parameters driving the long-wave radiation flux moving away from the Earth out into space in high-latitude regions. We address the solar activity effect on the changes in the temperature of the atmosphere and of the World Ocean. The aa–index of the geomagnetic activity (GA) was used as an SA proxy index. We discuss the results of analyzing the regularities and peculiarities of the tropospheric and sea surface temperature (SST) responses to both separate heliogeophysical disturbances and long-term changes in solar and geomagnetic activity. The structure of the tropospheric and SST temperature responses was shown to feature a spatial time irregularity. We revealed the regions, where long-term SST changes are determined mainly by SA variations.

Global Sea Sea Surface Temperatures Have Seen “Pretty Dramatic Turnaround,” Says 40-Year Meteorologist!

by P. Gosselin, July 15, 2018 in NoTricksZone

Hurricane threat to East Coast due to natural factors

First at his most recent Saturday Summary, the 40-year meteorologist first warns that in-close developing hurricanes of the sort seen in the 1930s are a risk to the US East Coast this year, due the current Atlantic temperature pattern. The reason has nothing to do with CO2 in the atmosphere, but because of natural sea surface temperature cycles.
