Susan Crockford: State of the Polar Bear Report 2023 (pdf)

by S. Crockford, 2023

Key Findings
* There were no reports from the Arctic in 2023 indicating polar bears were being harmed due to lack of summer sea ice habitat, in part because Arctic sea ice in summer has not declined since 2007. 
 
* Contrary to expectations, a study in Svalbard found a decrease in polar bears killed in defense of life or property over the last 40 years, despite profound declines in sea ice over the last two decades. 
 
* A survey of Southern Hudson Bay polar bears in 2021 showed an astonishing 30% increase over five years, which adds another 223 bears to the global total. 
 
* A concurrent survey of Western Hudson Bay polar bears in 2021 showed that numbers had not declined since 2011, which also means they have not declined since 2004. Movement of bears across boundaries with neighbouring subpopulations may account for the appearance of a decline, when none actually occurred. 
 
* The IUCN Polar Bear Specialist Group has ignored a 2016 recommendation that the boundaries of three Hudson Bay subpopulations (Western HB, Southern HB, and Foxe Basin) be adjusted to account for genetic distinctiveness of bears inhabiting the Hudson Bay region; a similar boundary issue in the western Arctic between the Chukchi Sea, and the Southern and Northern Beaufort subpopulations, based on known movements of bears between regions, has been acknowledged since 2014 but has not yet been resolved. 
 
* The US Fish and Wildlife Service and the IUCN Polar Bear Specialist Group, in their 2023 reports, failed to officially acknowledge the new-found South-East Greenland population as the 20th subpopulation, despite undisputed evidence this is a genetically distinct and geographically isolated group. Numbers are estimated at 234 individuals.

After All the Media Hype, Wildfires Across Southern Europe Were Completely Normal in 2023

by C. Morrison , Feb25, 2024 in TheDailySceptic

Writing in the Daily Telegraph last July, Suzanne Moore reported that the “world is on fire – and we can’t ignore it any longer”. She was noting the usual outbreaks of summer wildfires in southern Europe and suggested a retreat by cautious holiday makers in Rhodes away from one conflagration was “what climate refugees look like”. The Guardian was in similar hysterical mode observing that the lesson from Greece was “the climate crisis is coming for us all”. Such was the level of Thermogeddon interest last summer it is curious that final figures for areas burnt during the year are missing from mainstream media. In the five largest southern European countries for which the EU provides separate data – Portugal, Spain, France, Italy and Greece – 2023 was only the 20th highest in the modern satellite burnt acreage record going back to 1980.

This is perhaps not surprising. Fire ‘weather’ is a potent tool in stoking up general climate anxiety and helps promote the need for a collectivist Net Zero political solution. The Guardian used video footage of tourists moving away from one wildfire last year to claim “survival mode” could easily pass for a “TV climate crisis awareness raising campaign”. An Agence France-Presse report in the Guardian quoted EU spokesman Balazs Ujvari as stating that fires are getting more severe. “If you look at the figures every year in the past years, we are seeing trends which are not necessarily favourable.”

Let us look at some of the figures, starting first with the graph below compiled by the investigative climate writer Paul Homewood.

Why Climate Scientists were Duped into Believing Rising CO2 will Harm Coral and Mollusks

by J. Steele, Feb 24, 2024 in WUWT

Coral build reefs by producing limestone, or calcium carbonate. The great diversity of shell building mollusks, like clams and oysters, also build their shells out of calcium carbonate.  So, scientists assumed that these organisms just pulled carbonate ions from the surrounding sea water and joined it with abundant calcium ions to make reefs and shells, a process referred to as “calcification”. Thus, many scientists then expressed their heart-felt concerns that more CO2 will reduce the ocean’s carbonate ions and thus stress coral reef building and mollusk shell building.

Indeed, the increasing absorption of human produced carbon dioxide by the oceans can very slightly lower pH. In other words, more CO2 increases the oceans’ concentration of H+ ions. It is also unassailable science that when CO2 enters the water, it interacts with water molecules to produce both H+ ions and bicarbonate ions.  However, those H+ ions can then interact with carbonate ions and convert them to also form bicarbonate ions and reduce the pool of available carbonate ions. So, NOAA and hundreds of internet websites falsely told the world that “Ocean acidification slows the rate at which coral reefs generate calcium carbonate, thus slowing the growth of coral skeletons.”

However, climate scientists were apparently very ignorant regards the physiology of reef building and shell making.  In order for charged ions to pass through an organism’s lipid membranes and enter its calcification chambers, a specialized channel or transporter is required. But for over a decade now, the search for carbonate transporters has failed to find any such transporters in any of these organisms. However, abundant bicarbonate transporters (green rectangles) have been found and deemed important for making reefs and shells.

Observed humidity trends in dry regions contradict climate models

by Simpson et al., Dec 26, 2023 in PNAS

Significance

Water vapor in the atmosphere is expected to rise with warming because a warmer atmosphere can hold more moisture. However, over the last four decades, near-surface water vapor has not increased over arid and semi-arid regions. This is contrary to all climate model simulations in which it rises at a rate close to theoretical expectations, even over dry regions. This may indicate a major model misrepresentation of hydroclimate-related processes; models increase water vapor to satisfy the increased atmospheric demand, while this has not happened in reality. Given close links between water vapor and wildfire, ecosystem functioning, and temperature extremes, this issue must be resolved in order to provide more reliable climate projections for arid and semi-arid regions of the world.

Abstract

Arid and semi-arid regions of the world are particularly vulnerable to greenhouse gas–driven hydroclimate change. Climate models are our primary tool for projecting the future hydroclimate that society in these regions must adapt to, but here, we present a concerning discrepancy between observed and model-based historical hydroclimate trends. Over the arid/semi-arid regions of the world, the predominant signal in all model simulations is an increase in atmospheric water vapor, on average, over the last four decades, in association with the increased water vapor–holding capacity of a warmer atmosphere. In observations, this increase in atmospheric water vapor has not happened, suggesting that the availability of moisture to satisfy the increased atmospheric demand is lower in reality than in models in arid/semi-arid regions. This discrepancy is most clear in locations that are arid/semi-arid year round, but it is also apparent in more humid regions during the most arid months of the year. It indicates a major gap in our understanding and modeling capabilities which could have severe implications for hydroclimate projections, including fire hazard, moving forward.

UK Met Office Fails to Retract False Claim of “More Intense” Storms Due to Climate Change

by C. Morrison, Feb 23, 2023 in WUWT

The Met Office is refusing to retract a claim made by a senior meteorologist on BBC Radio 5 Live that storms in the U.K. are becoming “more intense” due to climate change. This is despite admitting in Freedom of Information (FOI) documents that it had no evidence to back up the claim. The Global Warming Policy Foundation (GWPF) noted the “false” claim seriously misled the public and demanded a retraction. The Daily Sceptic covered the story last Thursday and has since contacted the Met Office on three occasions seeking a response. “False information of this kind does much to induce climate anxiety in the population and I am sure you would agree such errors should be corrected by any reputable organisation,” it was noted. No reply was received – no retraction has been forthcoming.

The storm claim was made by Met Office spokesman Clare Nasir on January 22nd and led to an FOI request for an explanation by the investigative journalist Paul Homewood. The Met Office replied that it was unable to answer the request due to the fact that the information “is not held”. Interestingly, the Met Office’s own 2022 climate report noted that the last two decades have seen fewer occurrences of maximum wind speeds in the 40, 50, 60 knot bands than previous decades. The Daily Sceptic report went viral on social media with almost 3,000 retweets on X, while GWPF’s demand for retraction was covered by the Scottish Daily Express.

The lack of action by the state-funded Met Office is very interesting. Extreme weather is now the major go-to explanation for the opinion that humans largely control the climate, despite a general lack of scientific evidence. Backing away from this ‘settled’ narrative risks damaging a potent tool nudging populations across the world towards the collectivist Net Zero political project. Mainstream media usually take care to fudge their reporting of any direct link, using phrases such as ‘scientists say’ and sprinkling words ‘could’ and ‘might’ in the copy. The mistake Nasir made was to forget this basic requirement of broadcast fearmongering.

There appears to be an arrogance around the Met Office, an arrogance it shares with many other organisations and scientists promoting Net Zero …

GREAT SYNTHESIS

With respect to “Climate Change”, this website and my contribution to the discussion focuses on the data. I have a standing request/challenge to anyone (scientist or not) to provide an empirical Temperature/CO2 data set that shows CO2 driving the climate on any statistically significant historical time scale. Scientific proof requires empirical data. The Catastrophic Anthropogenic Global Warming (CAGW) theory does not have that empirical data (because that data does not exist).

The Great Barrier Reef could Die This Year?

by E. Worrall, Feb18, 2024 in WUWT

…

 

The Great Barrier Reef is in no danger of dying, at most it will change location a little. The reef is composed of an organism which has survived for at least 200 million years, through unimaginably catastrophic global extinction events and disasters, including the asteroid which killed the dinosaurs.

The reason that coral is so good at surviving great upheavals is that while adult coral is immobile, coral spawn is immensely mobile.

Every so often corals spawn. Corals produce immense clouds of microscopic eggs and sperms, which germinate into highly mobile microscopic coral larvae which seek out new places to colonise.

The Great Barrier Reef itself has moved location countless times over the millennia, the reef has only been at its current location for a few thousand years. Some Australian shorelines are composed of coral which lived thousands of years ago, during the Holocene Optimum, when the sea level was significantly higher than today. The Great Barrier Reef had and has no trouble changing location when climate change impacts sea conditions, such as when the world cooled after the end of the Holocene Optimum, and the sea waters retreated to today’s level.

And in fact, Australian coral coverage hit a record high a record high in 2022 – as an organism which is responsive to conditions, coral cover fluctuates wildly when conditions change.

Wrong Again: 50 Years of Failed Eco-pocalyptic Predictions

by M. Ebell & S.J. Milloy, 18 Sep 2019 in CompetitiveEnterpriseInstitute

Thanks go to Tony Heller, who first collected many of these news clips and posted them on RealClimateScience. 

SUMMARY

Modern doomsayers have been predicting climate and environmental disaster since the 1960s. They continue to do so today.

None of the apocalyptic predictions with due dates as of today have come true.

What follows is a collection of notably wild predictions from notable people in government and science.

More than merely spotlighting the failed predictions, this collection shows that the makers of failed apocalyptic predictions often are individuals holding respected positions in government and science.

While such predictions have been and continue to be enthusiastically reported by a media eager for sensational headlines, the failures are typically not revisited.

Chile Forest Fires–Climate Change?

by P. Homewood, Feb 15, 2024 in NotaLotofPeopleKnowThat

…

The wildfire is the worst disaster to hit Chile for more than a decade. At least 131 people have died, with a further 370 still missing. The hillside neighbourhoods it ripped through, destroying more 15,000 homes, are now a scorched wasteland of broken cement and steel.

Firestorms of this magnitude are a terrifying phenomenon, moving so fast and with such energy that they can kill people hundreds of metres away through radiant heat alone. But it is not unique.

Hawaii, California, France, Portugal, Canada, Greece and Australia have all been hit in recent years. In July 2022, when temperatures reached 40C for the first time in the UK, the residents of Wennington in east London witnessed nearly 20 houses burn down in a matter of minutes. The spark was a compost heap that had spontaneously combusted.

Experts are now asking: What’s causing these infernos? And is there anything that can be done to stop them?

Chile’s forest fire, like most, was preceded by unusually high temperatures, low humidity, and strong winds.

Arctic “Just-So Stories”: Bad Science by Climate Alarmists

by J. Steele, Feb 14, 2024 in WUWT

The Arctic Ocean was nick-named the “upside down Ocean” by Fridtjof Nansen. Nansen was a famous Norwegian zoologists, oceanographer, and Arctic explorer as well as winner of the 1922 Nobel Peace Prize. During his failed expedition to reach the North Pole, his boat, the Fram, got frozen in Arctic sea ice but eventually was exported by Arctic currents, along with Arctic sea ice, into the Atlantic through what is now named the Fram Strait.

Nansen named the Arctic Ocean the “upside down ocean” because contrary to other oceans, the surface waters are the coldest, while between 100 and 900-meters depths the ocean is warmer due to inflows and storage of warm salty Atlantic waters. Sea ice cover prevents the ventilation of that stored heat. However, increases in open water allows more heat ventilation which has raised Arctic air temperatures 2 to 7 times faster than the global average. Open waters have been increasing due to changes in wind direction and currents. Open water is not proof of melting.

NASA estimates that globally added CO2 has increased downward infrared and added “a little over 0.8 Watts per square meter” of energy which their Just So stories claim melted sea ice. But researchers (e.g. Kim 2019) have reported that over open water more winter heat, about 2 Watts per meter squared, is being ventilated heat away more than absorbed. That suggests radiative cooling!

When polar bears die, they die of starvation: new Nature paper is propaganda, not news

by S. Crockford, Feb 13, 2024 in PolarBearScience

Is it a coincidence that a paper reporting the results of a no-news study on polar bears, but which predicts future starvation due to climate change, was published two weeks to the day ahead of a climate change marketing event made up by the activist organization Polar Bears International? I doubt it.

And do I think the high-profile journal Nature Communications would not only agree to publish such a useless bit of propaganda but also rig the timing to advance the climate change emergency narrative? Silly question. And the media worldwide are of course lapping it up, happy for an excuse to promote the perils of climate change, see here, here, and here using images of fat polar bears. Image above is from the BBC headline, 13 February 2024.

They believe this strategy is effective because they think the public is stupid, but they are deluding themselves. Most people are now laughing at their obvious acts of desperation.

Polar bears are highly specialize for consuming large amounts of fat that they get from Arctic seals, whales, and walrus. Only a few vocal researchers outside main-stream polar bear science insist that polar bears could ever survive year-round by eating terrestrial foods (e.g., Ilses et al. 2013; Iverson et al. 2014; Gormezano and Rockwell 2013a,b; Prop et al. 2015; Rogers et al. 2015; Tartu et al. 2016).

There’s not aweek goes by when Iceland doesn’t feature prominently in the media, and even more so today with the evacuation of the population on 11 November following the awakening ofthe volcano at Grindavik, 40km southwest of Reykjavik.

The current eruption has been forecast since 21 July 2023, and was activated in December and on 14 January 2024. This is neither the first nor the last time that volcanism has made or will make news. Grindavik isnot the only eruption underway: between 40 and 50 of the 1,330 known volcanoes on Earth are erupting at any one time. This eruptive activity is accompanied by ‘disastrous’ effects such as frequent earthquakes, sulphur and ash aerosols, sub-glacial melting of the ice caps, glacio-isostatic discharges, and uplift… Yes, Iceland is under close survey… because it is located on an active hot spot.

Strong El Nino Conditions Prevails at The End of January 2024

by A. Patel, Feb 12, 2024 in WUWT

However, This El Nino Not Expected to Be as Strong As 1982-83 Or 1997-98 Or 2015-16 El Nino

Enso Status on 10th February 2024

Ashok Patel’s Analysis & Commentary :

The classification of El Niño events, including the strength labels, is somewhat subjective and can vary among meteorological and climate agencies. There isn’t a strict rule defining the specific number of consecutive Oceanic Niño Index (ONI) values that must be 2.0°C or above to categorize an El Niño event as “Super Strong.”

In general, a strong El Niño event is often characterized by ONI values reaching or exceeding +2.0°C. A Super Strong El Niño would typically involve sustained ONI value of +2.0°C or more. Hence for ease of understanding and comparing the strength of various Strong El Nino events, I propose to define an El Nino as a Super Strong event if  three consecutive ONI index is +2.0°C or more.

A brief history of the past El Nino events with the number of consecutive ONI +2.0°C or above:

In the year 1965 the highest ONI index during that El Nino were SON +2.0°C, OND +2.0°C

In the year 1972-73 the highest ONI index during that El Nino were OND +2.1°C NDJ +2.1°C DJF

In the year 1982-83 the highest ONI index during that El Nino were SON +2.0°C, OND +2.2°C NDJ +2.2°C DJF +2.2°C

In the year 1997-98 the highest ONI index during that El Nino were ASO +2.1°C SON +2.3°C, OND +2.4°C NDJ +2.4°C DJF +2.2°C

In the year 2015-16 the highest ONI index during that El Nino were ASO +2.2°C SON +2.4°C, OND +2.6°C NDJ +2.6°C DJF +2.5°C JFM +2.1°C

ONI Data has been obtained from CPC – NWS – NOAA available here

There have been three Super Strong El Nino events from 1950 onwards till date. The first such event was 1982-83 Super Strong El Nino with 4 consecutive ONI +2.0°C or above with highest ONI of +2.2°C twice. The second Super Strong El Nino event was 1997-98 with five consecutive ONI +2.0°C or above with highest ONI of +2.4°C twice. The third Super Strong El Nino event was 2015-16 with six consecutive ONI +2.0°C or above with highest ONI of +2.6°C twice. The current forecast and analysis does not support the 2023-24 El Nino to become a Super Strong El Nino.

Calls for Met Office to retract false ‘more intense storms’ claim

by GWPF, Feb 13, 2024

London, 13 February – The UK Met Office has been accused of seriously misleading the public about climate-driven storms in the UK.

On 22nd January, the day after Storm Isha, a senior meteorologist from the Met Office stated on BBC Radio 5 Live Breakfast that “when we see these storms they are more intense and that’s down to climate change”.

…

However, after being challenged through a FOI request to provide evidence for the claim that storms have become more intense, the Met Office was forced to admit they have no such evidence.

In its response, the Met Office also referred to its own UK Storm activity report which clearly states that “there is no compelling trend in maximum gust speeds recorded in the UK since 1969.”

We call on the Met Office to publish a full retraction of what is evidently a false and misleading claim.

NOTES FOR EDITORS

Met Office: Recent trends and future projections of UK storm activity: “This report found that there is no compelling trend in maximum gust speeds recorded in the UK since 1969, measured as the number of days more than 20 weather stations recorded gust speeds above 40, 50 or 60 knots.”

Met Office: State of the UK Climate 2022 (page 47):  “Storm Eunice [in 2022] was the most severe storm to affect England and Wales since February 2014, but even so, these storms of the 1980s and 1990s were very much more severe.”

New Study Finds No Evidence Of A CO2-Driven Warming Signal In 60 Years Of IR Flux Data

by K. Richard, Jan 11, 2024 in NoTricksZone

“The real atmosphere does not follow the GHG [greenhouse gas] GE [greenhouse effect] hypothesis of the IPCC.” – Miskolczi, 2023

CO2 increased from 310 ppm to 385 ppm (24%) during the 60 years from 1948 to 2008. Observations indicate this led to a negative radiative imbalance of -0.75 W/m². In other words, increasing CO2 delivered a net cooling effect – the opposite of what the IPCC has claimed should happen (Miskolczi, 2023).

Also, there is “no correlation with time and the strong signal of increasing atmospheric CO2 content in any time series,” which affirms “the atmospheric CO2 increase cannot be the reason for global warming.”

“The Arrhenius type greenhouse effect of the CO2 and other non-condensing GHGs is an incorrect hypothesis and the CO2 greenhouse effect based global warming hypothesis is also an artifact without any theoretical or empirical footing.”

Hottest 12 Months for 125,000 Years Claim Lacks Any Scientific Evidence

by C. Morrison, Jan 7, 2023 in TheDailySceptic, 

Last year humanity lived through the hottest 12 months in at least 125,000 years, reported an hysterical CNN, a frame of mind replicated throughout much of the mainstream media. Scientists have compared 2023’s “climate change fallout” to a “disaster movie”, added the U.S. cable news channel. All poppycock, needless to say, with a political Net Zero motive, and little if any scientific evidence to back it up. Accurate temperature records barely started before the 20th century, and recent measurements by fixed thermometers have been heavily corrupted by growing urban heat. It is in fact possible using proxy measurements to get a good idea of general temperature movements over the last 125,000 years. All the evidence points to periods of much higher temperatures, notably between 10,000 to 5,000 years ago. The latest science paper examining this trend has just been published, and it points to summer temperatures at least 1.5°C higher around 5,000 years ago in the eastern Mediterranean, at a time when civilisation was developing rapidly.

Mount Pinatubo eruption caused the major East China flood in 1991

by C. Xing & F. Liu, Jan 2023 in InnovativeGeoscience

The devastating flood of 2020 along the Yangtze River serves as a painful reminder of the 1991 East China’s largest flood. The latter event profoundly impacted the Yangtze-Huaihe River basins (YHRBs), causing extensive damage to both human lives and property1. The flood engulfed numerous villages and cities across seven provinces in East China, affecting over 15,000,000 hectares of farmland and approximately 100 million people. In response, millions of individuals in Anhui and Jiangsu provinces were forced to evacuate, with some seeking refuge on the banks of the Huaihe River. Gaining a comprehensive understanding of the contributing factors to this historically significant flood will enhance our ability to predict the East Asian summer monsoon and mitigate related climate disasters. Over the past three decades, this pursuit has been a persistent challenge1,2,3.

The 1991 East China flood was attributed to prominent intraseasonal oscillations, as evidenced by three episodes of heavy rain occurring from mid-May to mid-July over the YHRBs2, primarily linked to the persistent Meiyu front during early July1. The stable western Pacific subtropical high (WPSH), which plays a crucial role in influencing the East Asian monsoon by altering the convergence of southeasterly and southwesterly, provided substantial support for the prolonged existence of the Meiyu front in 19911; However, the reason behind the prolonged stability of the WPSH during that specific period remains a mystery.

No internal climate variability modes were reported to be in their most flood-favorable conditions during 1991, and the effect of external forcing on this flood disaster was not taken into consideration at all. Half a month before the flood, the Mount Pinatubo (located at 120.4ºE, 15.1ºN) in Luzon, the Philippines, explosively erupted on June 15th, 1991, which later is known as one of the strongest volcanic eruption in the past century. This eruption released approximately 20 Tg of SO2 into the tropical stratosphere4, which can form stratospheric aerosol that impact the global radiative balance. The stratospheric volcanic aerosol acts as a major forcing on the climate by cooling the global surface and slowing down the water cycle on annual to decadal timescales5. However, it remains unclear whether explosive volcanic eruptions have short-term impacts on the climate, particularly on the intraseasonal timescale.

UK Rainfall In 2023

Last year was a wet one in England & Wales, the 7th wettest on record. (The UK series has a similar result).

We routinely hear claims that the climate is wetter because a warmer atmosphere can hold more moisture, (while also being told we will get more droughts!). However the fact that we have had similarly wet years in the distant past, such as 1768, 1852, 1872, 1877, 1882, 1903 and 1960, rather demolishes that argument.

The major factor behind last year’s high rainfall was that the number of rain days was also one of the highest on record since 1931, when Met Office daily data begins. In short, annual rainfall was high because of weather, not climate.
