Nobel Winner Says Climate Science Now A ‘Massive Shock-Journalistic Pseudoscience’
by T. Andy, July 13; 2023 in ClimateChangeDispatch
Dr. John F. Clauser, a joint recipient of the 2022 Nobel Prize in Physics, has criticized the climate emergency narrative calling it “a dangerous corruption of science that threatens the world’s economy and the well-being of billions of people.”
Along with two others, Dr. Clauser, an experimental and theoretical physicist, was the 2022 recipient of the Nobel Prize for work done in the 1970s that showed “quantum entanglement” allowed particles such as photons to effectively interact at great distances, seemingly to require communication exceeding the speed of light.

He has criticized the awarding of the 2021 Nobel Prize for work in the development of computer models predicting global warming, according to a coalition of scientists and commentators who argue that an informed discussion about CO2 would recognize its importance in sustaining plant life.
In a statement issued by the CO2 coalition, “Nobel Laureate John Clauser Elected to the CO2 Coalition Board of Directors”, CO2 Coalition Dr. Clauser said that “there is no climate crisis and that increasing CO2concentrations will benefit the world.”
He criticized the prevalent climate models as being unreliable and not accounting for the dramatic temperature-stabilizing feedback of clouds, which he says is more than fifty times as powerful as the radiative forcing effect of CO2.
Dr. Clauser notes that bright white clouds are clearly the most conspicuous feature in satellite photos of the Earth.
These clouds are mostly produced by the evaporation of seawater by sunlight. They variably cover one-third to two-thirds of the Earth’s surface.
Most of the energy incident on the earth is in the form of visible sunlight. Clouds reflect sunlight energy back into space before it can reach the Earth’s surface to heat it.

Understanding the role of the sun in climate change
by N. Scafetta, July 6, 2023 in Andy May Blog
Although the sun provides nearly all the energy needed to warm the planet, its contribution to climate change remains widely questioned. Many empirically based studies claim that it has a significant effect on climate, while others (often based on computer global climate simulations) claim that it has a small effect.
The Intergovernmental Panel on Climate Change (IPCC) supports the latter view and estimates that almost 100% of the observed warming of the Earth’s surface from 1850–1900 to 2020 was caused by man-made emissions (AR6 WG1, pages 63, 425, and 962). This is known as the anthropogenic global warming (AGWT) theory.
I addressed this important paradox in a new study published in Geoscience Frontiers. The conundrum appears to arise from two sets of uncertainties: (i) the historical decades and long-term variations in solar activity are unknown; (ii) the sun may affect Earth’s climate through various physical mechanisms many of which are not fully understood and are not incorporated into the global climate models (GCMs).
It is important to notice that the AGWT is based solely on computer global climate model simulations that use total solar irradiance (TSI) records with very low multidecadal and long-term variability. The models also assume that the sun affects the climate system only through radiative forcing, although there is evidence that other solar processes related to solar magnetic activity (solar wind, cosmic rays, interplanetary dust, etc.) also affect the climate.

Where Does Ocean Heat Come From?
by Dr M. Wielicki, May 24, 2023 in ClimateChangeDispatch
First, do we really know the temperature and thus heat content of the ocean?
The ocean is vast and covers ~70% of the Earth’s surface, making it the largest system on the planet. Despite its size, only a small portion of the ocean has been explored and mapped in detail.
It is estimated that <20% of the world’s oceans have been mapped and explored to date. [emphasis, links added]
This is largely due to the difficulties and challenges associated with ocean exploration, such as the high pressure and extreme environments found in the deep ocean, as well as the high cost of research vessels, equipment, and technology.
Most of the ocean that has been explored in detail is located near the coasts or in shallow waters, where it is more accessible to research vessels and equipment, but usually far away from the heat sources of mid-ocean ridges.
The deep ocean, which makes up the majority of the ocean’s volume, remains largely unexplored, with less than 5% of the ocean floor having been mapped in high resolution.
Advances in technology, such as underwater drones and submersibles, are helping to improve our understanding of the ocean and its ecosystems, and it is likely that our knowledge of the ocean will continue to expand in the coming decades.
Temperature measurements in the ocean are typically taken using a variety of instruments. These instruments can be deployed from research vessels or from moored or drifting buoys, and they collect temperature data at different depths throughout the ocean.
The amount of the ocean that is measured for temperature varies depending on the method of measurement and the specific objectives of the research.
However, it is estimated that significantly less than 10% of the world’s oceans have been sampled for temperatures at depths greater than 2,000 meters.
Despite the relatively limited coverage of temperature measurements in the deep ocean, there are ongoing efforts to improve our understanding of the ocean’s temperature structure and variability.
