Early in 2011, NTZ readers and I entered a climate bet with Rob Honeycutt and climate warming dogmatist Dana Nuccitelli.
The bet, which I dubbed the Honeycutt Climate Bet for Charity, was whether globally the 2011-2020 decade would be warmer or cooler than the previous 2001-2010 decade. Myself and and a number of NTZ followers that bet the 2011-2020 decade would see no warming, or even cooling. Conversely Messieurs Honeycutt and Nuccitelli claimed global warming would continue, due to manmade greenhouse gas emissions, of course. To decide the winner of the bet, it was agreed that the RSS and UAH datasets would be used. Now we are at the end of 2020, and the data suffices to declare a winner. Chart: Dr. As we can see, before 2016 the global mean temperature had been cooling since 1998, thus establishing what came to be known as “the hiatus”. Ocean Temperature Update. By Andy May A considerable amount of new information on ocean temperature has been gathered since I last wrote about the subject in 2016 here.
In my last post on GHCN and the National Temperature Index, it appeared that ocean temperature trends and the thermal energy distribution in oceans dominate climate change. Land-based weather stations are invaluable for weather prediction, but they tell us very little about climate change. The common definition of climate is an overall change in temperature or precipitation over a period longer than 30 years.
But even 30 years is a short timeframe, 100 years might be better. Oceans cover 71% of Earth and they contain 99.93% of the thermal energy (“heat”) on the surface. We still do not have accurate information on the entire ocean, but we do have a lot more than in 2016. Arctic Ocean changes driven by sub-Arctic seas. New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.
The University of Alaska Fairbanks and Finnish Meteorological Institute led the international effort, which included researchers from six countries.

Now a recent study reveals the dynamics by which water influences temperatures over land as well. Evidence that Oceans not Man control CO2 emissions - New Climate Model. All the highest concentrations are downwind of warm water.
The Mediterranean gets very warm in summer so you can see the plume across the Middle East. Australia gets CO2 from the ocean between it and South Africa. South America gets CO2 from the Pacific upwind. Western USA from the Pacific, upwind. Southern Asia gets CO2 from the Indian Ocean, upwind. New Proxy Data Show Northern Europe Weather Variability In Sync With Natural Factors: Solar Activity, Oceanic Cycles.

June 2019 Another new paper, which of course will be ignored by the government-funded IPCC because it contradicts claims CO2 drives climate, shows that natural factors dominated the earth’s climate variability. A team of scientists led by Jerome Goslin have published a paper titled Decadal variability of north-eastern Atlantic storminess at the mid-Holocene: New inferences from a record of wind-blown sand, western Denmark in the journal Global and Planetary Change, suggesting climate variability is driven naturally. Image: NASA, public domain. Oceans Govern Climate. IPCC Fatal Error - Neglecting ocean thermal inertia. “Goodbye anthropogenic global warming.” – Dr Roger Higgs _________________ IPCC Fatal Error – Neglecting ocean thermal inertia The Earth is now cooling, says geologist Dr Roger Higgs, simply based on NASA’s online global monthly temperature chart showing that temperature peaked three years ago (February 2016) and is now declining quite steeply.
If the cooling continues, “man-made-global-warming believers will by 2021 have to admit they were wrong and that CO2 is blameless and that Svensmark’s sun/cosmic ray/cloud/temperature link is correct.” IPCC’s 2013 report (co-author physicist Dr M. Climate change. New Paper Finds Oceans Are Source Of “Natural Variability”, Drive “Temperature Extreme Indices” By P Gosselin on 5.
April 2019 A new paper published in the Journal of Weather and Climate Extremes by Dittus et al confirms what many skeptics has strongly suspected all along: There’s no trend in precipitation extremes and there isn’t much predictability either. New Study: The Tropical Atlantic Was 7.5°C Warmer Than Now While CO2 Was 220 ppm. By Kenneth Richard on 9. May 2019 Another new paper published in Paleoceanography and Paleoclimatology casts further doubt on the paradigm that says CO2 has historically been a temperature driver. Evidence from the tropical Atlantic indicates today’s regional temperatures (15.5°C) are 7.5°C colder than a peak temperatures (23°C) between 15,000 to 10,000 years ago, when CO2 hovered around 220 ppm.
Image Source: Reißig et al., 2019 “[T]he Tobago Basin core 235 subSSTMg/Ca record is highly variable and ranges from ~13-23°C, which is approximately three times as much as at Beata Ridge.. “[T]he subsurface temperature variability is a robust climate signal in the tropical W Atlantic. “In contrast to modern conditions Tobago Basin core 235 was influenced by a warm water mass between 30-10 ka BP, indicated by elevated subSSTMg/Ca (~2.5°C warmer than the modern conditions).” New Findings Contradict Alarmist Rahmstorf: Arctic/Greenland Ice Melt “Barely Impacting AMOC” By Die kalte Sonne (German text translated/edited by P Gosselin) Arctic ice melt barely impacting AMOC. Day After Tomorrow scenario remains fantasy, new study suggests. Figure: R. Curry, CC BY 3.0 Stefan Rahmstorf never tires of claiming the Gulf Stream system (AMOC, Atlantic Meridional Overturning Circulation) is being strongly weakened by the fresh water input of the melting Greenland ice.
The ‘Little Ice Age’ hundreds of years ago is STILL cooling the bottom of Pacific, researchers find. Continuous observations in the North Atlantic challenges current view about ocean circulation variability. Kevin Kilty May 10, 2019 From Physics Today (April 2019 Issue, p. 19)1: Science: The Deep Ocean Plays A ‘Leading Role’ In Global Warming. It’s Colder Now Than During The 1700s. Authors of a new paper published in the journal Science (Gebbie and Huybers, 2019) insist “the deep ocean ultimately plays a leading role in the planetary heat budget.” The global deep ocean has much less heat today than it had during both the Medieval Warm Period and the Little Ice Age. Image Source: Gebbie and Huybers, 2019 A Bottom-Up Heat Flux? The deep ocean may warm hundreds (to thousands) of years before hemispheric surface temperatures and CO2 concentrations do (Stott et al., 2007).
Image Source: Stott et al., 2007. Study reconstructing ocean warming finds ocean circulation changes may account for significant portion of sea level rise. Study suggests that in the last 60 years up to half the observed warming and associated sea level rise in low- and mid- latitudes of the Atlantic Ocean is due to changes in ocean circulation. Over the past century, increased greenhouse gas emissions have given rise to an excess of energy in the Earth system. More than 90% of this excess energy has been absorbed by the ocean, leading to increased ocean temperatures and associated sea level rise, while moderating surface warming. “Differences between ocean circulation and climate more generally” by Carl Wunsch 2010.
Post July 25th, 2018 Talking about the difference between ocean circulation and climate more generally is per se a strong massage that there is a strong correlation. - The Washington Post. Reevaluating the Ocean Conveyer Belt. Earth’s polar regions communicate via oceanic ‘postcards,’ atmospheric ‘text messages’ Caption Freshly drilled segment of the WAIS Divide ice core is brought to the surface. Precipitation and ocean circulation changes linked during the Little Ice Age. The Ocean Climate Spin Zone. This image shows the five major ocean gyres. It shows that gyres rotate in a clockwise direction in the Northern hemisphere and a counter-clockwise direction in the Southern hemisphere. New paper tries to disentangle global warming from natural ocean variations. This paper deals with the central argument that skeptics bring up about claims of global warming: How do you separate the temperature signal from the base components like natural variation, human land-use influence, micro-site bias, measurement errors and biases, and other factors to get the “true” global warming signal?
The answer is that you can’t, at least not easily. Improving Estimates of Long-Term Climate Sensitivity. One of the fundamental metrics in climate change research is equilibrium climate sensitivity: the amount that Earth’s long-term, near-surface temperatures will change in response to a doubling of atmospheric carbon dioxide concentrations. Previous research has shown that two spatially dependent processes—the variability of sea surface temperatures and the organization of initially scattered convection (known as convective aggregation)—largely control climate sensitivity by regulating feedbacks related to clouds and water vapor that can amplify or moderate Earth’s ability to radiate heat into space.

Bernaerts for his writings on this subject, excerpts of which appear below. Study: CO2 rise after last ice age didn’t need man-made influences, just the deep Pacific Ocean. Scientists trace atmospheric rise in CO2 during deglaciation to deep Pacific Ocean CORVALLIS, Ore. – Long before humans started injecting carbon dioxide into the atmosphere by burning fossil fuels like oil, gas, and coal, the level of atmospheric CO2rose significantly as the Earth came out of its last ice age. Carbon ‘leak’ may have warmed the planet for 11,000 years, encouraging human civilization. Bucket list: Historic global ocean temperature data – the missing pedigree is a comedy of errors.
