W. Hudson Bay sea ice not going away anytime soon as polar bears sit tight offshore

A broad band of sea ice is jammed up against the western shore of Hudson Bay, hanging on despite warm mid-July temperatures. Its unusual thickness suggests it wonโ€™t be gone anytime soon, which means most Western Hudson Bay polar bears will likely remain offshore for at least a few more weeks.

A broad band of sea ice is jammed up against the western shore of Hudson Bay, hanging on despite warm mid-July temperatures. Its unusual thickness suggests it wonโ€™t be gone anytime soon, which means most Western Hudson Bay polar bears will likely remain offshore for at least a few more weeks.

The dark blue in the โ€œdeparture from normalโ€ chart below shows just how unusual this phenomenon is for the northern reaches of Hudson Bay:

Sea ice thickness

For the week of 15 July 2024, sea ice on Hudson Bay is still at least 1m thick (medium green) but up to 2m thick in places (dark green). The thickest ice extends into Foxe Basin to the north:

Polar bears on ice

Bears tagged by University of Alberta researchers are almost all still on the ice โ€” only two have come ashore so far:

As I remarked last week, itโ€™s getting harder and harder for polar bear specialists to ignore the fact that their assumptions about sea ice concentration and polar bear behaviour during the ice-melt season was flat-out wrong. This year, some WH bears could again remain on the ice until August, despite what has been, on paper, theย earliest breakup year on recordย for Hudson Bay sea ice.

No, Newsweek, Sea Level Rise Is Not Causing Longer Days

This guest post by Geologist David Middleton discusses a recent claim in the media that sea level rise is causing longer days by changing the rate of the planetโ€™s rotation. However, Middleton reveals that there are major problems with the theory, not least of which that this is not a new phenomenon. As Climate Realism has covered dozens of times, models are not proof, and these studies certainly lean on modelling.

โ€˜Unprecedentedโ€™ Sea Level Rise Is Making Earthโ€™s Days Longer

Published Jul 15, 2024 at 3:00 PM EDT

Science Reporter

Our changing climate is impacting our planet in a huge number of waysโ€”ranging from powerful hurricanes and intense droughts to invasive species and ocean acidificationโ€”but there might be another bizarre effect that youโ€™ve never heard of.

Climate change might actually be slowly changing the length of a day on Earth, according to a new paper in the journal Proceedings of the National Academy of Sciences.

This is a result of sea levels risingโ€”because of increased temperatures and the melting of the polar ice capsโ€”thereby causing a redistribution of mass from the poles of our planet toward the equator.

Newsweek? Theyโ€™re still in business?

Newsweek, April 28, 1975

The PNAS article is pay-walled. However, the abstract says it allโ€ฆ

Abstract

The melting of ice sheets and global glaciers results in sea-level rise, a pole-to-equator mass transport increasing Earthโ€™s oblateness and resulting in an increase in the length of day (LOD). Here, we use observations and reconstructions of mass variations at the Earthโ€™s surface since 1900 to show that the climate-induced LOD trend hovered between 0.3 and 1.0 ms/cy in the 20th century, but has accelerated to 1.33 ยฑ 0.03 ms/cy since 2000. We further show that surface mass transport fully explains the accelerating trend in the Earth oblateness observed in the past three decades. We derive an independent measure of the decreasing LOD trend induced by Glacial Isostatic Adjustment (GIA) of โˆ’0.80 ยฑ 0.10 ms/cy, which provides a constraint for the mantle viscosity. The sum of this GIA rate and lunar tidal friction fully explains the secular LOD trend that is inferred from the eclipse record in the past three millennia prior to the onset of contemporary climate change. Projections of future climate warming under high emission scenarios suggest that the climate-induced LOD rate may reach 2.62 ยฑ 0.79 ms/cy by 2100, overtaking lunar tidal friction as the single most important contributor to the long-term LOD variations.

PNAS

Itโ€™s models all the way down. Thereโ€™s no way to measure fractions of milliseconds per century (ms/cy) changes in the length of day (LOD) over any time period, much less at a centennial to decadal scale. Might as well try to determine โ€œHow many angels can dance on the head of a pin?โ€

The LOD has been generally increasing over geologic time (Mitchell & Kirscher, 2023). As the Earth has pushed the Moon farther away, the Earthโ€™s rotation has slowed down.

1.33 ms/cy = 0.0000133 s/yr

At a rate of 0.0000133 seconds per year, in 80 million years, the sidereal day will be 18 minutes longer than it currently is.

Back in the Cretaceous Period (~80 mya), when sea level was much higher than it is today and there was little to no polar ice, the days were about 23.5 hours long (de Winter et al., 2020). The rate of LOD change from 80 mya to present (1950 AD) was about 2.25 ms/cy.

Figure 7 from de Winter et al., 2020

Allow this to sink in: The rate of LOD change from 80 mya to 1950 AD was about +2.25 ms/cy. The rate of LOD change since 2000 AD, allegedly driven by โ€œโ€˜unprecedentedโ€™ sea level rise is only +1.33 ms/cy.

Of course, there are no Cretaceous measurements of LOD. This is based on reconstructions from rudist shells and modelsโ€ฆ And the error bars are in days and hoursโ€ฆ not milliseconds.

Measuring LOD

Current LOD can be directly measured very precisely. Schreiber et al., 2023 employed โ€œa laser ring gyroscopeโ€ to measure changes in the sidereal day. They found that the LOD fluctuated by as much as 6 ms over the 120-day measurement period.

If LOD fluctuates by 6 ms over a two month period a 1.33 ยฑ 0.03 ms/century increase in the LOD is about as relevant as a 1-3 mm/yr rate of sea level rise is to a 1 meter daily tidal range.

Vineyard Wind Turbine Failure: Incident Details, Regulatory Response, and Industry Implications

On July 13, 2024, an offshore wind turbine at the Vineyard Wind 1 project experienced a significant blade failure, leading to debris washing up on Nantucketโ€™s beaches and prompting a federal shutdown of the wind farm. This incident raises obvious questions about the safety and reliability of offshore wind projects, as well as the regulatory framework governing this emerging industry.

From Watts Up With That?

By Charles Rotter

On July 13, 2024, an offshore wind turbine at the Vineyard Wind 1 project experienced a significant blade failure, leading to debris washing up on Nantucketโ€™s beaches and prompting a federal shutdown of the wind farm. This incident raises obvious questions about the safety and reliability of offshore wind projects, as well as the regulatory framework governing this emerging industry.

The Incident

Turbine Blade Failure

On Saturday, July 13, 2024, one of the turbines at the Vineyard Wind 1 site, located approximately 15 miles south of Marthaโ€™s Vineyard and Nantucket, suffered a blade breakage[1]. According to Vineyard Wind spokesperson Craig Gilvarg,

โ€œThe blade experienced a breakage approximately 20 meters out from the rootโ€

https://nantucketcurrent.com/news/vineyard-wind-reports-turbine-blade-damage-in-offshore-incident

The affected turbine was still in its commissioning phase and undergoing testing when the incident occurred.

Debris Washing Ashore

In the days following the incident, debris from the broken turbine blade began washing up on Nantucketโ€™s south shore beaches. Residents reported finding pieces of green and white foam, along with larger pieces of fiberglass, stretching from Madaket to Nobadeer[1]. The debris consisted of non-toxic fiberglass fragments ranging in size from small pieces to larger sections, typically green or white in color[1].

Beach Closures and Safety Concerns

As a result of the debris, six beaches on Nantucketโ€™s south shore were closed to swimming on Tuesday, July 16[7]. Nantucket Harbormaster Sheila Lucey stated,

โ€œThe water is closed to swimming on all south shore beaches, due to large floating debris and sharp fiberglass shardsโ€

https://nantucketcurrent.com/news/vineyard-wind-reports-turbine-blade-damage-in-offshore-incident

 While walking on the beaches was still permitted, officials strongly recommended wearing footwear due to the presence of sharp fiberglass shards and debris[1].

Regulatory Response

Federal Shutdown

In response to the incident, the federal Bureau of Safety and Environmental Enforcement (BSEE) ordered Vineyard Wind to shut down operations โ€œuntil further noticeโ€[2]. The BSEE, which oversees offshore energy projects, sent a team of experts to work closely with Vineyard Wind on analyzing the cause of the incident and determining next steps[4].

Investigation and Analysis

Vineyard Wind announced that GE, the projectโ€™s turbine and blade manufacturer and installation contractor, would be conducting the analysis into the root cause of the incident[1]. The company stated that it would continue working with federal, state, and locals to ensure the health and safety of its workforce, mariners, and the environment[1].

Vineyard Wind Project Overview

The Vineyard Wind 1 project consists of an array of 62 wind turbines, spaced 1 nautical mile apart on an east-west and north-south orientation[3]. The turbines are General Electric Haliade-X models, each capable of generating 13 megawatts of electricity[3]. The project includes two submarine cables that transmit the generated electricity to shore, with an onshore substation located in Hyannis[3].

Recent Regulatory Changes

In January 2023, regulations governing offshore renewable energy activities, including workplace safety and environmental compliance, were officially transferred from the Bureau of Ocean Energy Management (BOEM) to BSEE[5]. This transfer clarified the roles and responsibilities of BSEE and BOEM in promoting offshore renewable energy production[5].

Industry Implications

Safety Concerns

The Vineyard Wind turbine failure has raised questions about the safety and reliability of offshore wind projects. As the first major incident at a commercial-scale offshore wind farm in the United States, it may lead to increased scrutiny of safety protocols and equipment reliability in the industry.

Environmental Impact

While the debris from the turbine blade was reported to be non-toxic, the incident highlights potential environmental concerns associated with offshore wind development. The impact on marine life and coastal ecosystems will likely be a focus of ongoing discussions and future project assessments.

Economic Considerations

The shutdown of Vineyard Wind operations, even if temporary, could have economic implications for the project and the broader offshore wind industry. Delays in power generation and potential increases in operational costs may affect the projectโ€™s financial viability and investor confidence.

Regulatory Scrutiny

This incident may lead to increased regulatory oversight and potentially stricter safety standards for offshore wind projects. Regulators may revisit existing guidelines and consider implementing more rigorous inspection and maintenance requirements.

Public Perception

The visible impact of the turbine failure, with debris washing up on popular beaches, could influence public perception of offshore wind projects. This will likely lead to ramped up propaganda campaigns by project developers and industry advocates.

Paul Craney, a spokesperson for the Massachusetts Fiscal Alliance, expressed concerns about the incident and its timing:

โ€œNot even one offshore wind factory has been completed and weโ€™re already seeing red flags in the mildest of conditions. Now, the House is pushing for new authorization for so-called clean energy procurements, forcing ratepayers to subsidize this costly decision. Itโ€™s cronyism at its worst. The people of Massachusetts shouldnโ€™t be forced to spend their hard-earned money on precarious energy sources resulting in environmental cleanups and unreliable, unproven outcomesโ€

https://www.wgbh.org/news/local/2024-07-16/feds-halt-vineyard-wind-operations-after-weekend-turbine-incident

Looking Ahead

The Vineyard Wind turbine failure serves as a significant test case for the nascent U.S. offshore wind industry. As the sector continues to grow, with the Biden administration setting a goal of deploying 30 gigawatts of offshore wind by 2030[6], the response to this incident and its long-term implications will be closely watched by industry stakeholders, regulators, and the public.

Key areas to monitor in the coming months include:

1. The results of the root cause analysis being conducted by GE and any subsequent recommendations for turbine design or operational changes.

2. Potential updates to safety protocols or regulatory requirements for offshore wind projects.

3. The duration of the Vineyard Wind shutdown and its impact on the projectโ€™s timeline and financial performance.

4. Any changes in public sentiment or political support for offshore wind development, particularly in coastal communities.

5. The response of other offshore wind developers and how they may adjust their practices or communication strategies in light of this incident.

As the U.S. offshore wind industry continues to evolve, incidents like the Vineyard Wind turbine failure will likely shape its development, influencing everything from technological innovations to regulatory frameworks and public engagement strategies.

Former NSW Liberal minister calls on renewables sector to โ€˜put your mouth where your money isโ€™ in first speech as incoming Climate Change Authority chair

Peter Hannam Economics correspondentTue 16 Jul 2024 14.11 AEST

The incoming Climate Change Authority chair Matt Kean has issued a call to arms for the clean energy industry to โ€œenter the arenaโ€ and push back against vested interests seeking to erode public confidence in renewable energy.

Kean, a former energy minister in New South Wales and Liberal MP for another three weeks, told the Australian Clean Energy Summit 2024 in Sydney the industry had the science and the financial heft to counter the โ€œpropagandaโ€ of vested fossil fuel interests.

โ€œThose whose interest is maintaining the status quo and their own super profits and self-interest at the expense of Australian families and the national interest are hard at work undermining the transition,โ€ Kean told the event in his first major speech since being appointed authority head by the Albanese government last month.

Someone should explain โ€œsocial licenseโ€ to the new Climate Change Authority chairman Matt Kean.

From the AEMO Appendix to the 2024 Integrated System Plan for the National Electricity Market

โ€ฆ As part of the development of this infrastructure, the energy industry will need to establish and maintain social licence in local communities that are being asked to host new generation, storage, and transmission.

Establishing social licence for infrastructure development requires intentional and ongoing relationship building between organisations and communities to foster acceptance and trust. Communities also have their own intrinsic social licence โ€˜commitmentsโ€™ to and with each other (for example, the right for farmers to farm, rural communities to function harmoniously, and Aboriginal and Torres Strait Islander people to practice culture) which must be considered. Community acceptance of projects is fostered when organisations prioritise trust and deliver overall positive impact and is granted or withdrawn by the community in line with their social, cultural, and economic conditions โ€ฆRead more: https://aemo.com.au/-/media/files/major-publications/isp/2024/appendices/a8-social-licence.pdf?la=en

The AEMO does a good job of explaining what social license is, but perhaps they should have made more effort to explain why social license is so important.

The reason social license is important is the only thing preventing metal thieves from ravaging Australiaโ€™s electricity infrastructure like they do in South Africa, is rural people in Australia feel enough sense of community to pick up the phone and call the police when they see metal thieves attacking power pylons.

No affordable regime of patrols or security systems can possibly keep hundreds of miles of power lines and other sensitive energy infrastructure safe from thieves, without the wholehearted cooperation of locals.

If Matt Keen rams through his fast track planning approvals, brushing aside objections from locals, rural folk in Australia might switch from calling the police to offering metal thieves coffee and refreshments as they work.

But I doubt Matt Kean will listen to anyone offering this kind of advice. Kean seems like the kind of climate change authority chairman who is destined to learn things the hard way.


MP Keith Pittโ€™s response to Matt Keanโ€™s speech: โ€œMatt Kean is one of the problems, not the solutionโ€.


WUWT does not advocate metal theft or lawbreaking, our preferred resolution to standoffs like this is to promote public support for the cancellation of all Net Zero and climate policies, and the abolition of all climate change ministries, departments and authorities.

Another Fake Climate Case Bites theย Dust

Baltimore judge deals blow to left-wing effort
to punish oil companies for global warming

From Science Matters

Byย Ron Clutz

The decisive ruling against climate lawfare is reported at Washington Free Beacon Dem-Appointed Judge Tosses Major Climate Case Against Oil and Gas Producers in Blow to Environmental Activists. Excerpts in italics with my bolds and added images.

Baltimore judge deals blow to left-wing effort
to punish oil companies for global warming

A Baltimore judge tossed a landmark climate change lawsuit against more than two dozen oil and gas companies in a sizable defeat for environmental activists and Democrats that have touted the case.

Baltimore Circuit Court judge Videtta Brownโ€”who was appointed to the bench by former Gov. Martin Oโ€™Malley (D., Md.)โ€”ruled late Wednesday that the city cannot regulate global emissions and swatted down the cityโ€™s arguments that it merely sought climate-related damages from the defendants, not the abatement of their emissions. She further stated that the court does not accept the cityโ€™s contention that it does not seek to โ€œdirectly penalize emitters.โ€

โ€œWhether the complaint is characterized one way or another, the analysis and answer are the sameโ€”the Constitutionโ€™s federal structure does not allow the application of state law to claims like those presented by Baltimore,โ€ Brown wrote in her opinion (July 11). โ€œGlobal pollution-based complaints were never intended by Congress to be handled by individual states,โ€ she added.

In a statement to the Washington Free Beacon, the Baltimore City Department of Lawโ€™s chief of affirmative litigation division Sara Gross said the city respectfully disagreed with the opinion and would seek review from a higher court.

The ruling represents the latest setback for a broader left-wing effort to penalize oil companies for allegedly spreading disinformation about the role their products play in causing climate change. Over the past several years, Democratic-led states, cities, and countiesโ€”which are home to more than 25 percent of all American citizensโ€”have filed more than a dozen similar lawsuits.

Overall, if plaintiffs were to get their way, oil companies could be forced to pay billions of dollars in climate damages, a potentially catastrophic blow to their ability to stay in business.

Baltimore filed its original complaint in 2018, making it one of the first ever cases of its kind. After it was announced, former Democratic mayor Catherine Pugh said Baltimore was on the โ€œfront lines of climate change because melting ice caps, more frequent heat waves, extreme storms, and other climate consequences caused by fossil fuel companies are threatening our city and imposing real costs on our taxpayers.โ€

โ€œThese oil and gas companies knew for decades that their products would harm communities like ours, and weโ€™re going to hold them accountable,โ€ then-Baltimore city solicitor Andre Davis added at the time. โ€œBaltimoreโ€™s residents, workers, and businesses shouldnโ€™t have to pay for the damage knowingly caused by these companies.โ€

BP, Chevron, ExxonMobil, CITGO, ConocoPhillips, Marathon Oil, and Hess
were among the 26 entities listed as defendants in the filing.

โ€œThe Courtโ€™s well-reasoned opinion recognizes that climate policy cannot be advanced by the unconstitutional application of state law to regulate global emissions,โ€ Theodore Boutrous, who serves as counsel for Chevron, said in a written statement to the Free Beacon. โ€œThe meritless state tort cases now being orchestrated by a small group of plaintiffsโ€™ lawyers only detract from legitimate progress toward a lower carbon global energy system.โ€

The majority of the cases filed by Democratic prosecutors against the fossil fuel industry remain pending and are working their way through local courts, even as the oil industry has pushed for them to be litigated in federal courts.

In a ruling similar to the Baltimore court decision issued Wednesday, a Delaware state court in January delivered a setback to the State of Delawareโ€™s lawsuit against oil producers filed in 2020. That court found that alleged injuries stemming from out-of-state or global greenhouse gas emissions are preempted by the federal Clean Air Act.

Delaware, Baltimore, and most other jurisdictions pursuing the climate cases across the U.S. are being represented by the San Francisco-based law firm Sher Edling. The firm was founded to specifically spearhead these novel cases, but has received criticism for its dark money funding.

In 2022 alone, the most recent year with publicly available data, Sher Edling received grants worth a total of $2.5 million from the New Venture Fund, a pass-through fund managed by dark money behemoth Arabella Advisors, according to tax filings analyzed by the Free Beacon. That funding adds to the more than $8 million the firm received in prior years from dark money groups.

Although Sher Edlingโ€™s individual donors remain unknown, past funding for the firm has flowed from the Leonardo DiCaprio Foundation, MacArthur Foundation, William and Flora Hewlett Foundation, and Rockefeller Brothers Fund.

Sher Edling didnโ€™t respond to a request for comment.

Yale360: CO2 is Greening the Deserts โ€“ But it is Still Bad News

With CO2 Levels Rising, Worldโ€™s Drylands Are Turning Green

Despite warnings that climate change would create widespread desertification, many drylands are getting greener because of increased CO2 in the air โ€” a trend that recent studies indicate will continue. But scientists warn this added vegetation may soak up scarce water supplies. 

BY FRED PEARCE โ€ข JULY 16, 2024

โ€ฆ

And Australia is far from alone. From Africaโ€™s Sahel to arid western India, and the deserts of northern China to southern Africa, the story is the same. โ€œGreening is happening in most of the drylands globally, despite increasing aridity,โ€ says Jason Evans, a water-cycle researcher at the Climate Change Research Centre of the University of New South Wales in Sydney, Australia. 

What is going on? The primary reason, most recent studies conclude, is the 50-percent rise in carbon dioxide concentrations in the atmosphere since preindustrial times. This increased C02 is not just driving climate change, but also fast-tracking photosynthesis in plants. By allowing them to use scarce water more efficiently, the CO2-rich air fertilizes vegetation growth in even some of the driest places.

โ€ฆ

The negative impacts of hotter, drier climates have not gone away; but in most arid lands this CO2 fertilization effect is proving more powerful. This supercharging of plant growth seems unlikely to be short-lived if fossil-fuel burning causes atmospheric concentrations of CO2 to continue rising. A new modeling studypublished last month found that it will, if anything, become more marked in the coming decades. โ€œMost of the global drylands are projected to see an increase in vegetation productivity,โ€ says Evans, a coauthor of the study.

โ€ฆ

Water is not the only potential limiting factor in plant growth in arid lands. The availability of nutrients, particularly nitrogen, is another. That raises questions about whether the benefits of CO2 fertilization will continue to increase. But recent climate modeling suggests that the greening of drylands is unlikely to slow before mid-century and may speed up.

โ€ฆ

So is this all good news? Far from it, ecologists warn. Most obviously, the greening created by agricultural irrigation of fields can play havoc with scarce water reserves and obliterate valuable arid-land ecosystems

What can I say? The climate science prediction that CO2 would cause deserts to expand turns out to be dead wrong โ€“ but itโ€™s still bad news.

Wobbly apocalypse โ€” Humans to blame for making days longer, throwing planet off balance

Climate change makes the Earth wobble on its axis. Now, if you shower too long, and enjoy that beefsteak too much, you could affect the tilt Earths axis. Are you feeling guilty yet, or just fed up that modern science is indistinguishable from the prophesies of Neolithic shamen?

Earth is wobbling and days are getting longer โ€” and humans are to blame

By Harry Baker

New studies, which utilized AI to monitor the effects of climate change on Earthโ€™s spin, have shown that our days are getting increasingly longer and that our planet will get more wobbly in the future. These changes could have major implications for humanityโ€™s future.

Weโ€™re talking of fractions of a millisecond:

Initially, these changes will be imperceptible to us, but they could have serious knock-on effects, including forcing us to introduce negative leap seconds, interfering with space travel and altering our planetโ€™s inner core, researchers warn.

So itโ€™s probably your air-conditioner in Power Mode, but it could be due to crustal plates shifting:

A day on Earth lasts about 86,400 seconds. But the exact time it takes our planet to complete a single rotation can shift by tiny fractions of milliseconds every year due to a number of factors, such as tectonic plate movements, changes to the inner coreโ€™s rotation and gravitational tugging from the moon.

And it might have something to do with the moon, or the inner molten core of Earth, which might be affected by the sunโ€™s magnetic field. I mean, we really have no idea, but letโ€™s remake our electricity grid just in case we lose a millisecond?

When we melt the ice at the poles and the seas rise higher over the equator, the Earth spins slower just like the iceskater who spreads out their arms:

Over the past few decades, the rate of ice loss from Earthโ€™s polar regions, particularly Greenland and Antarctica, has been increasing rapidly due to global warming, leading to rising sea levels.

Which is all very well, except Antarctica hasnโ€™t warmed in a thousand years, the coastline hasnโ€™t changed since we first took photos of it, and 600 Pacific Islands are not sinking or shrinking.

Plus only 4 years ago, scientists were telling us the days were speeding up

All those emissions sped the world up, and now all those emissions are slowing us down?

In 2020 scientists made a startling discovery. They found that, instead of slowing down, the Earth has started to spin faster. It is now spinning faster than at any time in the last 50 years. In fact, the shortest 28 days on record all occurred during 2020. โ€” ScienceFocus

At the Guardian theyโ€™re afraid the extra millisecond will disrupt internet traffic, or screw up financial transactions and GPS. Itโ€™s be like Y2K all over again, and we all know how catastrophic that was.

Look at the language here, these people so want to believe we are Gods:

Climate crisis is making days longer, study finds

Damien Carrington, The Guardian

The phenomenon is a striking demonstration of how humanityโ€™s actions are transforming the Earth, scientists said, rivalling natural processes that have existed for billions of years.

The change in the length of the day is on the scale of milliseconds but this is enough to potentially disrupt internet traffic, financial transactions and GPS navigation, all of which rely on precise timekeeping.

The other thing thatโ€™s persisted for billions of years is radical sweeping climate change. Like this (below). Nature has been screwing up our GPS, our financial transactions and our space travel for millions of years and we just didnโ€™t know it.

Wait til you see how solid this research is โ€” like climate modeling but with less data:

I mean, how accurate were the clocks at recording milliseconds in 1901? We didnโ€™t even define what a second was until 1968. and itโ€™s not like weโ€™ve got many measurements of changes in Earthsโ€™ core since then either. Ask Jules Verne?

In the new study, published July 15 in the journal PNAS, researchers used an advanced artificial intelligence program that combines real-world data with the laws of physics to predict how the planetโ€™s spin will change over time.

And this is a Nature paper.  Yet the whole thing could have been an AI school project from start to finish. An AI awarded an AI a grant, which produced a โ€œpaperโ€ which an AI editor thought was worth publishing, and AI journalists turned into nonsense headlines, which an AI audience clapped. And no one anywhere thought to ask whether the researchers knew Antarctica is not melting, and seas are barely rising, and length of day was shrinking only a few years ago.

Big Government is strangling real science.
