    Ancient ice reveals scores of gigantic volcanic eruptions

    Ice cores drilled in Antarctica and Greenland have revealed gigantic volcanic eruptions during the last ice age. Sixty-nine of these were larger than any eruption in modern history. According to the University of Copenhagen physicists behind the research, these eruptions can teach us about our planet’s sensitivity to climate change.
    . . .
    Determining Earth’s climate sensitivity is an Achilles heel of current climate models. Svensson concludes:

    “The current IPCC models do not have a firm grasp of climate sensitivity—i.e., what the effect of a doubling of CO2 in the atmosphere will be. Vulcanism can supply us with answers as to how much temperature changes when Earths atmospheric radiation budget changes, whether due to CO2 or a blanket of sulfur particles. So, when we have estimated the effects of large volcanic eruptions on climate, we will be able to use the result to improve climate models.” [bold added]

    But a ‘large volcanic eruption’ has nothing in common with 0.04% of the Earth’s atmosphere being CO2.

    ‘Visionary’ US astrophysicist Eugene Parker dead at 94

    Eugene Parker, a pioneering American astrophysicist whose mathematical prediction that charged particles streamed from stars in a solar wind was met with disbelief before he was ultimately vindicated, has died aged 94, NASA said on Wednesday.

    Parker was hailed as a visionary who laid the groundwork for the field of heliophysics, the science of understanding the Sun and its interactions with Earth and the solar system, including space weather.

    In 2018, he became the first person to witness the launch of a spacecraft bearing his name, NASA’s Parker Solar Probe.
    . . .
    “The first reviewer on the paper said, ‘Well, I would suggest that Parker go to the library and read up on the subject before he tries to write a paper about it, because this is utter nonsense,'” Parker told UChicago News in 2018.

    Cloud seeding might not be as promising as drought-troubled states hope

    As an atmospheric scientist, I have studied and written about weather modification for 50 years. Cloud seeding experiments that produce snow or rain require the right kind of clouds with enough moisture, and the right temperature and wind conditions. The percentage increases in precipitation are small, and it’s difficult to tell when snow or rain fell naturally and when it was triggered by seeding.
    . . .
    The results of about 70 years of research into the effectiveness of cloud seeding are mixed.

    Most scientific studies aimed at evaluating the effects of seeding cumulus clouds have shown little to no effect. However, the results of seeding wintertime orographic clouds—clouds that form as air rises over a mountain—have shown increases in precipitation.

    A solar power station in space? How it would work, and the benefits it could bring

    The UK government is reportedly considering a £16 billion proposal to build a solar power station in space.

    Yes, you read that right. Space-based solar power is one of the technologies to feature in the government’s Net Zero Innovation Portfolio. It has been identified as a potential solution, alongside others, to enable the UK to achieve net zero by 2050.

    But how would a solar power station in space work? What are the advantages and drawbacks to this technology?

    Space-based solar power involves collecting solar energy in space and transferring it to Earth. While the idea itself is not new, recent technological advances have made this prospect more achievable.

    Quantum technology could make charging electric cars as fast as pumping gas

    While the maximum charging speed increases linearly with the number of cells in classical batteries, the study showed that quantum batteries employing global operation can achieve quadratic scaling in charging speed. To illustrate this, consider a typical electric vehicle with a battery that contains about 200 cells. Employing this quantum charging would lead to a 200 times speedup over classical batteries, which means that at home charging time would be cut from 10 hours to about 3 minutes. At high-speed charging stations, the charge time would be cut from 30 minutes to mere seconds.

    https://phys.org/news/2022-03-quantum-technology-electric-cars-fast.html

    What that might do to battery life is another matter.

  7. Stuart Brown says:

    From the article:

    “… quantum technologies are still in their infancy and there is a long way to go before these methods can be implemented in practice. Research findings such as these, however, create a promising direction and can incentivize the funding agencies and businesses to further invest in these technologies”

    So given enough cash we’ll find a way to make the energy leap from the charger into each cell of the battery, without needing a cable, by entanglement or something… Promise.

    Climate Model Democracy
    Posted by Andy May March 11, 2022

    In the computer modeling world, a world I worked in for 42 years, choosing one model, that matches observations best, is normal best practice. I have not seen a good explanation for why CMIP5 and CMIP6 produce ensemble model means. It seems to be a political solution to a scientific problem. This is addressed in AR6 in Chapter 1,[1] where they refer to averaging multiple models, without considering their accuracy or mutual independence, as “model democracy.” It is unclear if they are being sarcastic.
    . . .
    Conflating natural variability with short-term noise is a mistake, as is assuming natural variability is short term. It is not clear that CMIP6 model uncertainty is properly understood. Further, using unvalidated models to “measure” natural variability, even when an attempt is made to separate out model uncertainty, assumes that the models are capturing natural variability, which is unlikely. Long-term variability in both the Sun and the oceans is explicitly ignored by the models.

    Electric cars have a very dirty secret
    The technological flaws of battery-powered vehicles have not gone away

    Volvo confirmed that EVs are far “dirtier” out of the factory gate, as the resource extraction for an electric drive train is so carbon-intensive.

    But few EV owners will ever clock up enough miles on what they believe to be clean energy to ever make up the difference.

    Given the typical global fuel generation mix, a typical EV driver will need to drive 92,000 miles to reach CO2 emission parity with the petrol-powered equivalent, while a driver in the EU, where the energy mix contains more nuclear and renewables, some 52,000 miles. And that’s without changing the battery once. This isn’t well known amongst pious EV owners, for whom the car is a kind of face mask on wheels.

    New transistor could cut 5% from world’s digital energy budget

    “So you need something that you can shrink smaller, if possible. But above all, you need something that works differently than a silicon transistor, so that you can drop the power consumption, a lot.”

    So rather than depend on electric charge as the basis of its approach, the team turned to spin: a magnetism-related property of electrons that points up or down and can be read, like electric charge can, as a 1 or 0.

    The problems of trying to provide enough storage to back up a fully wind and solar system without fossil fuels are so huge and so costly that you would think that everyone pushing the “net zero” agenda would be completely focused on these issues. And given that the issues are quite obvious, you would think that such people would be well down the curve with feasibility studies, cost studies, and demonstration projects to make their case on how their plans could be accomplished. Remarkably, that is not the case at all. Instead, if you read about the plans and proposals in various quarters for “net zero” in some short period of years, you quickly realize that the people pushing this agenda have no clue.

    Seafloor spreading has been slowing down
    by American Geophysical Union

    A new global analysis of the last 19 million years of seafloor spreading rates found they have been slowing down. Geologists want to know why the seafloor is getting sluggish.
    . . .
    Today, spreading rates top out around 140 millimeters per year, but peaked around 200 millimeters per year just 15 million years ago in some places, according to the new study.
    . . .
    The seafloor is destroyed in subduction zones, where oceanic crust slides under continents and sinks back into the mantle, and is reforged at seafloor spreading ridges. This cycle of creation and destruction takes about every 180 million years, the age of the oldest seafloor. The crust’s magnetic record tracks this pattern, producing identifiable strips every time the Earth’s magnetic field reverses.

    Drivers face ‘speed limiter devices fitted in all new cars’ under new government plans’
    16/04/2022

    Brits could face having speed limiters fitted to all new cars under government plans to improve safety on the roads, it has been reported.

    Measures that would see lower speeds and reduce pollution by cars would also be backed by environmental groups.

    But critics have also hit out at the “big brother” idea which would mean greater control by the state on people’s lives.
    . . .
    A provisional agreement has been reached to make speed limiters mandatory for all new cars sold in Europe from July 6 2022. Even though the UK left the EU in 2020, it still follows the same regulations for new cars.

    Another rule that is implemented into UK law has made it mandatory for all new cars to be fitted with intelligent speed assistance by July 7 2024.

    Limiters use a technology called Intelligent Speed Assistant (ISA) to detect the local speed limit in the area using GPS and video data. They then eliminate the choice to go above the legal speed, or make it harder to.

    The physics of a singing saw

    “How the singing saw sings is based on a surprising effect,” said Petur Bryde, a graduate student at SEAS and co-first author of the paper. “When you strike a flat elastic sheet, such as a sheet of metal, the entire structure vibrates. The energy is quickly lost through the boundary where it is held, resulting in a dull sound that dissipates quickly. The same result is observed if you curve it into a J-shape. But, if you bend the sheet into an S-shape, you can make it vibrate in a very small area, which produces a clear, long-lasting tone.”

    The geometry of the curved saw creates what musicians call the sweet spot and what physicists call localized vibrational modes—a confined area on the sheet which resonates without losing energy at the edges.

    Importantly, the specific geometry of the S-curve doesn’t matter. It could be an S with a big curve at the top and a small curve at the bottom or visa versa.
    . . .
    The researchers also found that they could tune the localization of the mode by changing the shape of the S-curve, which is important in applications such as sensing, where you need a resonator that is tuned to very specific frequencies.

    A fire broke out in a property in south-west London after a man burnt timber on an open fire in his living room to heat his home, London Fire Brigade has said.

    Investigators said the cause of the blaze was identified as an open fire being used instead of gas central heating, prompting the fire service to issue an urgent safety warning.

    It is understood to have also been caused by combustible items placed too close to an open fire.

    London Fire Brigade said there have been more than 100 fires involving open fires, log burners and heaters in the last few months alone.

    The brigade now fears the rise in energy bills could result in a surge of fires as people resort to alternative means to heat their homes throughout the colder spells of the year.

    Making Climate Skepticism Illegal: The Regime’s Crackdown On Disinformation
    BY BRIGGS ON MAY 9, 2022

    Two new, and two successful, power grabs by the Regime were completed last week.

    The first was the start of the Disinformation Governance Board, under the Department of Homeland Security. This creates a mechanism to define official thoughtcrimes. I repeat: if official disinformation exists there necessarily must exist Official Truths (which are only coincidental with Truths), and therefore there must exist an entity in charge of creating and regulating them.

    The second grab was creation of the Office of Environmental Justice, under the Department of Justice. There is no such thing as environmental justice. But such a fiction can be defined with respect to The Science (as in “Listen to The Science!”). The Science is research provided by Experts. And Experts, you recall, are educated credentialed important individuals who align with and are supported by the Regime, directly or indirectly.

    The first thing you will have noticed is that all things must now be named for what they are not. That is the well known nature of advertising.

    The second obvious observation is that these new agencies are two aspects of the same thing: official control of information.

    The DGB will be the clearing house for Official Truths (OTs) as we discussed, and the OEJ will be (among other things) one of its police forces for certain kinds of non-political thoughtcrimes.

    This study utilizes time-series data devised to measure solar irradiation, sea surface temperatures, and temperatures in the lower atmosphere to gain a better understanding of how gravitational effects from the moon and Jovian planets (Jupiter, Saturn, Uranus, and Neptune) influence solar activity and climatic conditions on Earth. Then, standard statistical methods are used to determine the degree of correlation among these time series and construct a Jovian gravitational model. The study reveals a direct relationship between JSUN perihelion coincidences and TSI amplitude variations in cycles up to 4,450 years. The forced solar accumulation of heat in oceans introduces a new phase relation between solar forced cycles and new climate variation. Earth’s axis nutation cycles have coincidences with lunar nodal tide cycles and lunar forced sea surface temperature cycle periods up to 446 years. Earth’s temperature variation shows coincidence with constructive and destructive interference between lunar-forced and accumulated solar-forced temperature variations in oceans. Upcoming events have a computed modern temperature maximum in 2025 and a deep minimum in 2070. Interference between solar-forced temperature cycles of 333,2142, and 4,450 years and a lunar-forced temperature cycle of 445 years indicates that “The Little Ice Age” covers a total period of 820 years from 1330 to 2150 A.D. and an upcoming temporary cold climate period from 2070 to 2150.

    Scaling, Mirror Symmetries and Musical Consonances Among the Distances of the Planets of the Solar System

    Michael J. Bank1† and Nicola Scafetta2*†

    https://www.frontiersin.org/articles/10.3389/fspas.2021.758184/full

    Orbital systems are often self-organized and/or characterized by harmonic relations. Inspired by music theory, we rewrite the Geddes and King-Hele (QJRAS, 24, 10–13, 1983) equations for mirror symmetries among the distances of the planets of the Solar System in an elegant and compact form by using the 2/3rd power of the ratios of the semi-major axis lengths of two neighboring planets (eight pairs, including the belt of the asteroids). This metric suggests that the Solar System could be characterized by a scaling and mirror-like structure relative to the asteroid belt that relates together the terrestrial and Jovian planets. These relations are based on a 9/8 ratio multiplied by powers of 2, which correspond musically to the interval of the Pythagorean epogdoon (a Major Second) and its addition with one or more octaves. Extensions of the same model are discussed and found compatible also with the still hypothetical vulcanoid asteroids versus the transneptunian objects. The found relation also suggests that the planetary self-organization of our system could be generated by the 3:1 and 7:3 resonances of Jupiter, which are already known to have shaped the asteroid belt. The proposed model predicts the main Kirkwood asteroid gaps and the ratio among the planetary orbital parameters with a 99% accuracy, which is three times better than an alternative, recently proposed harmonic-resonance model for the Solar System. Furthermore, the ratios of neighboring planetary pairs correspond to four musical “consonances” having frequency ratios of 5/4 (Major Third), 4/3 (Perfect Fourth), 3/2 (Perfect Fifth) and 8/5 (Minor Sixth); the probability of obtaining this result randomly has a p < 0.001. Musical consonances are “pleasing” tones that harmoniously interrelate when sounded together, which suggests that the orbits of the planets of our Solar System could form some kind of gravitationally optimized and coordinated structure. Physical modeling indicates that energy non-conserving perturbations could drive a planetary system into a self-organized periodic state with characteristics vaguely similar of those found in our Solar System. However, our specific finding suggests that the planetary organization of our Solar System could be rather peculiar and based on more complex and unknown dynamical structures.
