The ‘approximately 18 years’ may be a hint at an influence of the lunar nodal cycle (18.6~ years), although the moon isn’t mentioned in the paper. This memory period is influencing variations in regional air temperatures which could improve climate projections, say the researchers, noting that ‘state-of-the-art climate models significantly underestimate ocean memory, estimating it at only 8-10 years.’

A research team has developed a new approach to measure ocean memory and found that the North Atlantic Ocean has a memory of approximately one to two decades, significantly surpassing previous estimates of a few years, says ScienceDaily.

Ocean memory refers to the persistence of ocean conditions and is a major source of predictability in the climate system beyond weather time scales.

However, the fundamental question of “how long does the ocean remember?” has been unclear. The difficulty in identifying ocean memory is due to continual changes in atmospheric forcing masking the longer-term effects of ocean circulation.

Reported in a paper published in Geophysical Research Letters, the research team were able to quantify ocean memory by tracking the evolution of ocean temperatures in response to a single extreme atmospheric event.

The authors find that there are fast and slow responses involving an immediate atmospheric effect on surface temperature and a delayed ocean redistribution of heat.

The authors attribute the extended memory of the North Atlantic Ocean to the slow pace of changes in the ocean circulation and heat transport.

Their findings suggest that fluctuations in ocean temperatures exert a significant influence on regional climates, such as air temperatures, for over a decade.

It also offers support that careful analyses of observations may enhance future climate projections over a decade.

Dr Hemant Khatri, from the University of Liverpool and lead author of the paper, said: “The study addresses a fundamental question of what ocean memory truly is. The new ocean memory framework reveals physical mechanisms responsible for multi-year ocean memory and paves the way for new methods for evaluating climate models.”

Professor Ric Williams, from the University of Liverpool and co-author of the paper, said: “This is the first time we’ve been able to measure ocean memory. We find that, in contrast to observation-based estimates, state-of-the-art climate models significantly underestimate ocean memory, estimating it at only 8-10 years. This significant discrepancy in ocean memory could have substantial implications for the accuracy of decadal climate predictions from these models.”

“Our work shows how the ocean affects our climate and how understanding the ocean temperature changes leads to enhanced skill over the next decade in climate projections.”

As we guessed, it appears that most of Ed Miliband’s £21 billion bung to carbon capture projects will end up being paid for through our energy bills.

The Telegraph report that a senior civil servant has revealed that three quarters of the cost will be funded by levies on electric and gas bills. Although this will be spread out over a number of years, the overall cost to households would be over £500 each.

So much for Miliband’s lie that energy bills would be cut by £300 a year!

So far the carbon saving from the first £4 billion tranche of funding is only reckoned to save 2 Mt of CO2 a year.

Graeme Weber reports on the history revealing multiple holes in IPCC claimed “settled science.” HIs paper is  IPCC – Miss/Diss information? shared with me by email.  Graeme is an earth scientist, retired consulting geologist and advocate for nuclear energy. His text is in italics with my bolds and added images.

Several years ago, the cry from the IPCC (International Panel on Climate Change) was ‘the science is settled’. This should have been a ‘red flag’ to any scientists who know that science is never settled. This is especially so in such a complex system, as Mother Earth’s climate. It is now 32 years since the first IPCC Report was issued. Many claims in this and later IPCC reports have since been debunked especially the ‘Hockey Stick’ graph of Mann, Bradley and Hughes (1999) where Mann was finally taken to court to reveal his calculations that subsequently led to him losing a court case and the IPCC getting embarrassed, as monumental errors and manipulation of data was exposed.

Another erroneous claim by the IPCC was that 97% of Scientists believed in Global Warming. How did they make this claim? It was based on a study  in the Proceedings of the National Academy of Sciences of the United States of America (2010) who reviewed publication and citation data for 1,372 climate researchers, 908 of whom had authored 20 or more publications on climate, and found that 97–98% of the climate researchers (the 908) most actively publishing in the field support the tenets of ACC (Anthropogenic Climate Change) outlined by the IPCC, and the relative climate expertise and scientific prominence of the researchers unconvinced of ACC are substantially below that of the convinced researchers. Well, how strange people who research in this field and rely on financial support believe in Global Warming!

Another study by Dr Soon and Dr Michael Connolly and His son Dr. Ronan Connolly released in 2023 was on Rural and Urban temperature records in the Northern Hemisphere. This study is similar to articles reported by JoNova and Jennifer Marohasy in Australia on temperature measurement equipment and stations in Australia with encroaching buildings, air conditioners, changes to recording gear and BOM changing temperature records by outright manipulation and homogenisation. The most obvious one is changing from reading manually by a person at a set time each day to continuous recording machines every minute or so, so increasing the likelihood of higher daily temperatures. In many cases BOM (Australian Bureau of Meteorology) claimed significant warming trends by starting at a cool point rather than a warm point.

The BOM never mentions the extreme temperatures recorded throughout Australia in January 1896 nor the elevated temperature during the 1930’s decade culminating in 1939 Black Friday. In the days preceding these fires, the Victorian state capital, Melbourne, experienced some of its hottest temperatures on record at the time: 43.8 °C (110.8 °F) on 8 January and 44.7 °C (112.5 °F) on 10 January. On 13 January, the day of the fires, temperatures reached 45.6 °C (114.1 °F), which stood as the hottest day officially recorded in Melbourne for the next 70 years. Now BOM issue weather alerts when the temperature reaches 30 degrees!

The study by Soon et al clearly shows that temperature measuring stations are increasingly being influenced by solar radiation being absorbed by bitumen and concrete and released through the night. One of the most remarkable illustrations of this effect was an aerial thematic view of the City of Rome at 8.30am in the morning. Vapour trails of early aircraft take-offs are clearly visible. The airport is hot (usually site of temperature gauges) surrounding country is relatively cold

Another reveal over the last 30 years is the number of Land Temperature stations (LTS).  Total LTS in the Northern Hemisphere has declined from 5,000 to 2,000 stations but rural stations have declined from 500 to 200. This has been particularly relevant in the Northern Hemisphere where the most remote Artic stations (northern and coldest) have been closed. The product of this is the average temperature of these remote areas has risen. Mathematics 101. Soon et al have examined 4,500 temperature stations in China, USA the Artic and Ireland that show a warming trend of 0.89º C per Century in Urban areas whereas Rural Stations only show 0.55ºC per Century. This is a significant difference.

Another factor producing higher biased temperatures is the IPCC technique of ‘homogenisation’ where a particular area has all the temperature readings added together then divided by the number of stations. As is expected the number of urban stations read higher than rural ones thus increasing the overall temperature average. Taking the overall rural average the warming trend results in an increase of 0.9ºC since 1850.

So, Antonio Guterres the UN Secretary General prognosis that the ‘World is boiling’ is wrong, stupid and farcical. Soon et al believe the warming is more likely due to Total Solar Radiance whereas the IPCC believe it is due to a trace gas CO2 a plant food. It is interesting to note that commercial greenhouses use about 1,000–1,300 ppm under ideal circumstances. A lower level (800–1,000 ppm) is recommended for raising seedlings (tomatoes, cucumbers and peppers) as well as for lettuce production. Currently the world CO2 sits at 423ppm.

Al Gore (former USA Vice Presidential candidate) has made numerous predictions in his film ‘Inconvenient Truth’ most if not all have proved false. His biggest claim was the Arctic Ocean will be ice free by 2013 or was that 2014 or even 2015! When this did not happen, the argument was that overall, the ice was drastically thinning. Last month October 2024 icebreakers were madly trying to extract ships in the northern passages some two weeks before expected, from Arctic ice closing in.

At the other end of our world in Antarctica numerous IPCC papers claimed that the West Antarctic Ice Sheet was about to, or already collapsing because of warmer waters were circulating caused by Climate change. However, a new study in 2017 found 91 new volcanic vents to add to the 47 volcanoes already known to exist under this ice sheet. As volcanic activity waxes and wanes ice melt will continue in this hot volcanic zone. Whether this ice sheet melts or not it is certainly more probable the effects are more controlled by volcanic activity rather than circulating waters. The IPPC reports also failed to acknowledge that ice buildup was occurring at other points in Antarctica.

Is CO2 bad? One remarkable and observable thing is that trees and plants take in carbon dioxide through stomata in their leaves. Since plants first invaded continents (perhaps chasing higher concentrations of carbon dioxide) science has a very good record of the CO2 gas concentrations in the atmosphere. The larger the Stomata the lower the CO2 concentration.

Approximately 580 Ma years ago the concentration was just under 3000ppm. This was soon after a major ice age around 750Ma years ago. The concentration has been steadily falling, since apart from two very low CO2 events occurred around 430Ma and 280Ma and if at any stage the CO2 concentration had dropped below 150ppm then we would not be here as all plants would have died. Other scientific studies show there is a lag between periods when the Earth’s temperature increases and CO2 concentrations rise. Maybe just maybe, the Industrial Revolution saved the planet!

Other scientific papers are showing that the world climate has a natural buffering system. As temperatures rise evaporation increases over the oceans that cover 71% of the earth’s surface. Increased precipitation has a marked cooling effect and together with increased CO2 will lead to greater vegetation growth to feed the worlds increasing population. Desertification will likely decrease. Maybe Central Australia will bloom and make the central Australian Aboriginal communities wealthy.

A paper provided to the Court of Appeals, The Hague November 2023 by Richard Lindzen Professor of Earth, Atmospheric, and Planetary Sciences, Emeritus Massachusetts Institute of Technology, William Harper Professor of Physics, Emeritus Princeton University and Steven Koonin University Professor, New York University, Senior Fellow at the Hoover Institute wrote:

‘We are career physicists who have specialized in radiation physics, dynamic heat transfer and computer modelling for decades, subjects directly relevant to the global warming debate. Each of us has published over 200 peer-reviewed papers, many on the science of climate or closely related subjects. In our opinion, the District Court of The Hague findings that “dangerous” climate change and extreme weather are caused by CO2 emissions from fossil fuels are contradicted by the scientific method and only supported by the unscientific methods of government opinions, consensus, peer review, and cherry-picked or falsified data. Science demonstrates fossil fuels, and CO2 will not cause dangerous climate change. Rather, there will be disastrous consequences for people worldwide if fossil fuels and CO2 emissions are reduced to “net zero,” including mass starvation’.

What if the Net Zero fossil fuels and CO2 policy was in effect in 1750 and CO2 did not rise from 280 ppm to 420 ppm? There would be 21% less food worldwide. Therefore it can be concluded that the Earth’s surface temperature is rising but not at the rate the IPCC would have you believe. As Bjorg Lomborg is saying it is much better to prepare for this eventuality something we cannot change than try to reduce a trace gas that is essential for life.

I fear for those who have trusted governments like they did the Covid science. The false claims of Government about an approaching Armageddon causing an induced psychosis resulting in stunts paralysing normal economic industry. These stunts such as hanging from pylons or gluing to windows, throwing paint, disrupting parliament. Where will it all end? The destruction of our civilisation?
