Overblown warming claims, arising from climate modellers obsessing over trace gases, may be unstoppable but some measure of reality surfaces briefly here.
– – –
A top scientific journal which claimed that global warming may already be unstoppable has been forced to issue a clarification after being accused of potentially causing “unnecessary despair”, says The GWPF.

Scientific Reports sought to publicise a study by Norwegian scientists with a doom-laden press release headlined: “Ending greenhouse gas emissions may not stop global warming.”

After being strongly criticised by leading British scientists, the journal issued a revised press release which admitted that the prediction was based on a particular computer model and said the results should be tested by “alternative models”.

Tropical beach


Another day, another false climate alarm bites the dust – or sand. It’s ‘flawed computer models’ time, again.
– – –
Sandy beaches are much less vulnerable to rising seas than was claimed in a recent European Commission study which caused “unnecessary alarm”, research has found.

Beaches will survive by migrating landwards as the sea level rises as long as they are given space to move and not impeded by sea walls and other structures on the coast, the research shows.

The new findings contradict claims made in March in a study by the commission’s joint research centre, which supplies scientific evidence to guide EU policy, reports The Times (via The GWPF).

The study was publicised with a press release headlined “Climate Change: Life’s a (disappearing) beach”.

A key component of the Gulf Stream has markedly slowed over the past century—that’s the conclusion of a new research paper in Nature Communications published on August 7, says Phys.org.

The study develops a method of tracking the strength of near-shore ocean currents using measurements made at the coast, offering the potential to reduce one of the biggest uncertainties related to observations of climate change over the past century.

“In the ocean, almost everything is connected,” said Christopher Piecuch, an assistant scientist in the Physical Oceanography Department at the Woods Hole Oceanographic Institution (WHOI) and author of the study. “We can use those connections to look at things in the past or far from shore, giving us a more complete view of the ocean and how it changes across space and time.”

Piecuch, who specializes in coastal and regional sea level change, used a connection between coastal sea level and the strength of near-shore currents to trace the evolution of the Florida Current, which forms the beginning of the Gulf Stream.

The Gulf Stream flows north along the Southeast Atlantic Coast of the United States and eventually east into the North Atlantic Ocean, carrying heat, salt, momentum, and other properties that influence Earth’s climate.

Because nearly continuous records of sea level stretch back more than a century along Florida’s Atlantic Coast and in some parts of the Caribbean, he was able to use mathematical models and simple physics to extend the reach of direct measurements of the Gulf Stream to conclude that it has weakened steadily and is weaker now than at any other point in the past 110 years.

One of the biggest uncertainties in climate models is the behavior of ocean currents either leading to or responding to changes in Earth’s climate. Of these, one of the most important is the Atlantic Meridional Overturning Circulation, or AMOC, which is a large system or “conveyor belt” of ocean currents in the Atlantic that includes the Gulf Stream and that helps regulate global climate.

Piecuch’s analysis agrees with relationships seen in models between the deeper branches of the AMOC and the Gulf Stream, and it corroborates studies suggesting that the deeper branches of AMOC have slowed in recent years.

Solar cycle 14 – was the fourteenth solar cycle since 1755, when extensive recording of solar sunspot activity began. The solar cycle lasted 11.5 years, beginning in January 1902 and ending in July 1913. The maximum smoothed sunspot number (SIDC formula) observed during the solar cycle was 107.1, in February 1906 (the lowest since the Dalton Minimum) – Wikipedia


Another bunch of climate alarmist predictions get exposed as over-the-top doom-mongering — literally, in this case.

Coral reef islands across the world could naturally adapt to survive the impact of rising sea levels, according to new research reported at Phys.org.

Coral reef islands across the world could naturally adapt to survive the impact of rising sea levels, according to new research.

The increased flooding caused by the changing global climate has been predicted to render such communities—where sandy or gravel islands sit on top of coral reef platforms—uninhabitable within decades.

However, an international study led by the University of Plymouth (UK) suggests that perceived fate is far from a foregone conclusion.

Better to follow the actual observations than the Hollywood-style scenarios of headline-chasing climate alarmists.

PA Pundits - International

By Dr. Jay Lehr~

Alarms over rising oceans continue to sound. Politicians, actors, authors, and climate activistswarn us regularly that the massive ice sheets in the Antarctic, and the Arctic, are melting. They remind us that in a matter of decades, oceans will rise to the point where they will destroy many coastal cities, and the process would become irreversible.The International Panel on Climate Change (IPCC) and the media have speculated and prophesied that by 2100, we would have ocean levels between five to ten feet higher.

Graphic photoshopped pictures of New York skyscrapers show buildings flooded several floors high. Miami is shown vanishing under the sea. All said to be a result of increasing CO2 followed by melting ice resulting in a rise in our ocean levels.Most of our readers suspect great exaggeration but do not understand…

Less than a year ago NASA was reporting from Greenland: Jakobshavn Glacier Grows for Third Straight Year, and ‘The glacier grew 22 to 33 yards (20 to 30 meters) each year between 2016 and 2019.’ So this new report may be, to some degree at least, already obsolete since it says: ‘The largest thinning rates were between 4 and 6 m a−1 in Jakobshavn and Kangerlugssuaq glaciers’.

Sea levels have risen by 14mm since 2003 due to ice melting in Antarctica and Greenland, scientists have said.

Nasa launched a satellite to measure global heights in 2018 and spotted the rise after bouncing laser pulses against sheets of ice, says the London Evening Standard.

The study found that Greenland lost an average of 200 billion tonnes of ice per year, and Antarctica lost an average of 118 billion tonnes.

One billion tonnes of ice is enough to fill 400,000 Olympic-sized swimming pools.

A team led by researchers at the University of Washington compared the data with measurements taken by the satellite between 2003 and 2009.

The findings, published in the journal Science, found the loss of ice from Antarctica and Greenland outweighs any gains from accumulated snow.

Significant changes since 2007 or so are observed but not explained, which seems to leave them open to interpretation. To get that ball rolling the recent solar slowdown could be mentioned.
A 2015 NASA study said that ‘an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.’

Using the latest satellite technology from the European Space Agency (ESA), scientists from the University of Bristol have been tracking patterns of mass loss from Pine Island — Antarctica’s largest glacier, reports SciTechDaily.

They found that the pattern of thinning is evolving in complex ways both in space and time with thinning rates now highest along the slow-flow margins of the glacier, while rates in the fast-flowing central trunk have decreased by about a factor of five since 2007.

Estimates are always uncertain to some degree – that’s why they’re called estimates. So an uncertain estimate can’t be all that useful. They admit ‘there are still key deficiencies in the models’ — but these are usually ignored when alarmist climate predictions are headlined. As ever, ice-related sea level claims should be taken with a large pinch of salt.

Estimates used by climate scientists to predict the rate at which the world’s ice sheets will melt are still uncertain despite advancements in technology, new research shows.

These ice sheet estimates feed directly into projections of sea-level rise resulting from climate change, says Phys.org.

They are made by measuring how much material ice sheets are gaining or losing over time, known as mass balance, to assess their long-term health.

Snowfall increases the mass of an ice sheet, while ice melting or breaking off causes it to lose mass, and the overall balance between these is crucial.

Although scientists now have a much better understanding of the melting behaviour of ice sheets than they did in previous decades, there are still significant uncertainties about their future melt rates, researchers found.

What if anything can ‘uncertain predictions’ about the climate tell us that might be worth taking seriously? Excitable headline-chasing fearmongers do nothing to help, especially when proved wrong.

The ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness, reports ScienceDaily.

The more specific climate scientists are about the uncertainties of global warming, the more the American public trusts their predictions, according to new research by Stanford scholars.

But scientists may want to tread carefully when talking about their predictions, the researchers say, because that trust falters when scientists acknowledge that other unknown factors could come into play.

In a new study published in Nature Climate Change, researchers examined how Americans respond to climate scientists’ predictions about sea level rise.

H/T Climate Change Dispatch

In which a scientific project gets dropped, or ignored, when it fails to produce the expected or hoped-for incriminating ‘climate change’ related data.

There is a striking disparity between sea-level datasets favored by climate catastrophists and actual observations, which mostly exists in their imaginations, writes Jack Weatherall for Quadrant Online.

The splendiferous east coast of Tasmania never ceases to please with all its myriad landscapes.

So it was a little discombobulating to recently pass a sign planted hard against the flow of traffic following the serpentine track that threads the coastal communities, proclaiming ‘Climate Change Is Killing the Planet’.

As it was only about eight degrees at the time, I was reasonably confident I would make my destination before something akin to the fate of the death star transpired and, thankfully, I was right.

It did, however, get me to thinking of how corrupt the science of the carbon cycle has truly become in the hyperbolic atmosphere of climate politics.

This is a prelude to a new IPCC report. It’s an exercise in mixing problems that do exist, like biofuels using too much land, with ones that don’t, like excess trace gases in the atmosphere. The end product is the usual alarm-and-confusion brand of propaganda for man-made warming believers, with wild talk of meltdowns, deadly extremes and so forth. More like a Hollywood script than anything resembling reality – but over-the-top stuff like this seems to be standard fare in much of the media nowadays.

The overlapping crises of climate change, mass species extinction, and an unsustainable global food system are on a collision course towards what might best be called an ecological land grab, says Phys.org.

Coping with each of these problems will require a different way of using of Earth’s lands, and as experts crunch the numbers it is becoming unnervingly clear that there may not be enough terra firma to go around.

A world of narrowing options threatens to pit biofuels, forests and food production against each other.

The climate apocalypse bandwagon first got going nearly as long ago as the first moon landing, but shows no signs of falling apart despite a dismal record of no-show of its forecasts, as Climate Change Dispatch explains. The urge to blame humans for any and all vagaries, real or imagined, of the climate seems deep-rooted despite this ongoing lack of predictive success.

This month, The Wall Street Journal celebrated its 130th anniversary by republishing salient articles spanning that period, including this retrospectively illuminating report from February 2, 1978:

A climatic disaster, triggered by the continued burning of oil and coal, could result in the submergence of much of Florida, Holland and other low-lying areas in the next 50 years, an Ohio State University scientist predicted… “I contend that a major disaster – a rapid five-meter rise in sea level caused by deglaciation of West Antarctica – may be imminent or in progress, after atmospheric carbon dioxide has only doubled,” John H. Mercer, a glacier geologist, asserted.

By some miracle, fortunately, Florida and Holland were still with us over a decade later.

Atafu atoll in the Pacific [image credit: NASA Johnson Space Center]


Good news for the rest of humanity may be bad news for climate miserablists, but hey-ho. Another global warming canard takes a knock.

The Pacific’s low-lying reef islands are likely to change shape in response to climate change, rather than simply sinking beneath rising seas and becoming uninhabitable as previously assumed, new research has found.

Atoll nations such as Tuvalu, Tokelau and Kiribati lie only a few metres above sea level and are considered the world’s most vulnerable to global warming, with fears their populations will become climate refugees as waters rise, says Phys.org.

But a study published this week found that such islands “morphodynamically respond” to the environment because they are composed of the skeletal remains of tiny reef-dwelling organisms, rather than solid rock.

Straining sanity to the limit, they want to use the Earth’s climate as some kind of legal excuse to try and extort money from Australians. All based on carbon dioxide mythology of course.

Indigenous residents of low-lying islands off northern Australia will submit a landmark complaint with the United Nations on Monday accusing the government of violating their human rights by failing to tackle climate change, reports Phys.org.

The Torres Strait Islanders will tell the UN Human Rights Committee in Geneva that rising seas caused by global warming are threatening their homelands and culture, lawyers representing the group said.

The lawyers, from the non-profit ClientEarth, said the case was the first of its kind to be lodged with the UN equating government inaction on climate change to a human rights violation.

This is a critique by Professor Nils-Axel Mörner and two colleagues of a recent article discussing problems with IPCC sea level claims.

The original article by Ken Haapala, President, Science and Environmental Policy Project (SEPP) starts:

Rising Seas – At Sea, or Shore? The latest Summary for Policymakers of its full Assessment Report by the UN Intergovernmental Panel for Climate Change (IPCC, AR-5, SPM, 2014) declared that sea level rise is accelerating.

Numerous studies have come out in support of that view. As shown in the 2008 report of the Nongovernment International Panel for Climate Change (NIPCC, 2008), with the ending of the last Ice Age about 18,000 to 20,000 years ago, sea levels have risen about 400 feet (120 meters).

At first, the rise was slow, then rapid, then for the past several thousand years slowing to about 7 to 8 inches (18 to 20 cm) per century. There is some question about the variation during the Little Ice Age and the period following it called the industrial period since 1850.

The latest over-the-top climate policy from the American west coast.

American Elephants

The California Coastal Commission is set to empower local governments to pursue eminent domain to take 1,100 miles of coastline in order to prepare for sea level rise. Local jurisdictions will implement a “managed retreat” policy that will allow taking and demolishing coastal homes and businesses.

This will allow communities to dismantle and relocate power plants, 250 miles of highway, 1,500 miles of roads and 110 miles of railway.

This battle is going to be fun, when the state tries to take Environmentalist Tom Steyer’s coastal property, in the name of saving the rest of California from the horrors of global warming and its sea level rise.

Scientists are not sure that there is any rise in sea level at all. What little discrepancy they see may simply be coastline shrinking.

Roy Spencer PhD. noted recently that “Climate Models are warming the Global Lower Atmosphere 67% Faster than the average…

Allowing for limitations of global sea level data, it seems the endless cries of alarm and scary scenarios are not justifiable at this time.

Climatologist Dr. Judith Curry: Mean global sea level has risen at a slow creep for more than 150 years; since 1900, global mean sea level has risen about 7-8 inches.

The implications of the highest values of projected sea-level rise under future climate change scenarios are profound, with far-reaching socioeconomic and environmental implications.

However, these projections are regarded as deeply uncertain and the highest of these projections strain credulity…

We shouldn’t have to put up with this constant diet of climate misinformation from people who should, or maybe do, know better.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Science Magazine had fun taking the mickey out of this GOP Rep, but failed to uncover some seriously erroneous statements by a supposed “climate scientist” at the U.S. House of Representatives Science, Space and Technology Committee earlier this week.

This is their account (my bold):

The Earth is not warming. The White Cliffs of Dover are tumbling into the sea and causing sea levels to rise. Global warming is helping grow the Antarctic ice sheet.

Those are some of the skeptical assertions echoed by Republicans on the U.S. House of Representatives Science, Space and Technology Committee yesterday. The lawmakers at times embraced research that questions mainstream climate science during a hearing on how technology can be used to address global warming.

A leading climate scientist testifying before the panel spent much of the two hours correcting misstatements.

The purpose of the hearing was to focus on how…

Antarctic sea ice [image credit: BBC]


Another mystery in ‘settled’ climate science. Experts now say they ‘acknowledge that the Antarctic is an important factor in climate change, but still a poorly understood one’. Snowfall is arriving on the land mass while ice is drifting into the sea – as usual in that part of the world. What is needed is accurate data before reaching for the alarm bell.
H/T The GWPF

Previous climate change models predicted that global sea levels would rise by a meter by the year 2100 due in part to melting Antarctic ice, but those estimates have proven to be flawed.

Over the past century, the Antarctic has gone from being a vast Terra Incognita to a continent-sized ticking time bomb: according to NASA, Antarctica has lost “approximately 125 gigatons of ice per year [between 2002 and 2016], causing global sea level to rise by 0.35 millimeters per year.”
