The West Intends Energy Suicide: Will It Succeed?

by T. Doshi, Oct 10, 2020 in Forbes

Suicide is viewed as a crime in many countries. In a court of law, it is a serious charge and the evidence needs to be conclusive for such an accusation to stand (e.g., did you actually see him attempt to jump off the bridge?). But when societies (or at least their leaders) attempt it, one can say that it safely falls under the rubric of the sovereign right to misrule. In the hallowed tradition of Western liberal democracy, so long as its political leaders are elected in free and fair elections, misrule leading to societal death by suicide is merely an unfortunate outcome of either gross negligence or culpable intention led by, say, an ideology of de-industrialization. Nevertheless, let us proceed with the case for the prosecution.

The Circumstantial Evidence Of Societal Suicide

The first piece of evidence is an astonishing article published last week in the Boston Review by a professor of anthropology in Rutgers University . The good professor opined that Zimbabwe and Puerto Rico “provide models for what we might call ‘pause-full’ electricity”. The West, he continues, has created a vast infrastructure for generating and consuming electricity 24/7, 365 days a year. Since this is based on “planet-destroying fossil fuels and nuclear power”, we need to emulate the aforementioned poor countries and save the climate by giving up the demand for the constant supply of electricity.

To be fair, the professor also noted that the Zimbabweans and Puerto Ricans did not choose to accept electricity rationing but were imposed upon by the gross negligence and corruption of their governments. The professor cannot be lightly dismissed, and the Boston Review shares its domicile with MIT and Harvard University, the temples of wisdom in modern Western civilization. And the Review has its share of kudos, at least for those of a particular persuasion: “When it comes to publishing fresh and generative ideas, Boston Review has no peer” says Robin D. G. Kelley, Professor of American History at the University of California, Los Angeles and Naomi Klein, activist and New York Times NYT-0.5% best-selling author, opines that “Boston Review is so good right now.”

Let us move on to our second piece of evidence, this time from the other side of the “climate emergency” aisle.  Professor Fritz Vahrenholt is a giant among environmental circles in Germany. (The country is well known as the world’s leading champion for all things environmental and for pushing Europe to “net zero emissions by 2050”.) Prof. Vahrenholt holds a doctorate in chemistry and started his professional career at the Federal Environmental Agency in Berlin (responsible for the chemical industry) before joining the Hessian Ministry of the Environment. From 1984 until 1990 he served as state secretary for environment, from 1991 till 1997 as minister for energy and environment in the state of Hamburg.

One day before the publication of the Boston Review article on October 5th, Prof Vahrenholt stated baldly in a German TV interview that climate science was “politicized”, “exaggerated”, and filled with “fantasy” and “fairy tales”. He pronounced that “The [Paris] Accord is already dead. Putin says it’s nonsense. […] The Americans are out. The Chinese don’t have to do anything. It’s all concentrated on a handful of European countries. The European Commission in massively on it. And I predict that they will reach the targets only if they destroy the European industries.” He lambasted Germany as a country “in denial when it comes to the broader global debate taking place on climate science”. He went on to characterize Europe’s recent push for even stricter emissions reduction targets to madness akin to Soviet central planning that is doomed to fail spectacularly.

Les chercheurs prenant le plus l’avion sont… les experts du climat

by Le Point, Oct 29,  2020

Selon une étude britannique, les climatologues voyagent en moyenne davantage en avion que les scientifiques spécialisés dans d’autres domaines.

Les arroseurs arrosés. Les climatologues alertent régulièrement et, à raison, sur les effets sur le climat des déplacements en avion, fortement émetteurs de gaz à effet de serre. Mais une étude publiée en ce mois d’octobre dans la revue Global Environmental Change vient mettre le doigt sur certains de leurs comportements. Selon cette étude britannique coordonnée par l’université de Cardiff, et relayée par Nature et Courrier International, les experts en réchauffement climatique sont les scientifiques qui voyagent le plus souvent en avion, en comparaison avec leurs collègues d’autres disciplines. Au total, plus de 1 400 chercheurs, provenant de 59 pays différents et de domaines scientifiques divers, ont été interrogés.

En moyenne, les experts du climat, qui représentaient environ 17 % des personnes sollicitées, prennent l’avion à raison de cinq fois par an. En comparaison, les chercheurs spécialisés dans d’autres disciplines disent effectuer quatre trajets par an en avion. Les vols effectués par les climatologues sont davantage domestiques qu’internationaux. Toutefois, ils avancent souvent des raisons professionnelles pour ces trajets, ce qui n’est pas forcément le cas de leurs autres collègues scientifiques. Les professeurs spécialisés dans le dérèglement climatique voyagent en avion environ neuf fois par an en moyenne, contre huit fois pour leurs collègues d’autres spécialités.

“Where’s the sea ice?” Right where it’s been for most of the Holocene.

by D. Middleton, Oct 30, 2020 in WUWT

This is sort of a sequel yesterday’s post: Where’s the sea ice? 3 reasons the Arctic freeze is unseasonably late and why it matters.

What a difference a day can make! Looks like it’s starting to crust over:

Figure 0. Daily sea ice extent map, October 29, 2020. (NSIDC)

…

…

Two key takeaways:

  1. Maximum Holocene sea ice extent occurred within the past 500-1,000 years at every location.
  2. The current sea ice extent is higher at all of the locations than over 50% to 85% of the Holocene.

While this doesn’t tell us what the sea ice extent was in million km2, it does tell us that the modern sea ice extent is larger than it was over most of the Holocene Epoch. It also tells us that the areas of currently seasonal sea ice extent have been seasonal or reduced over most of the past 5,000 years and ice-free or nearly ice-free over the prior 3,000 years or so. Here’s is the Kinnard graph plotted at the same horizontal scale as the Stein cross section:

Can China, the world’s biggest coal consumer, become carbon neutral by 2060?

by D. Normile, Sep 29, 2020 in Science AAAS

China’s surprise pledge last week to cut its net carbon emissions to zero within 40 years has reignited hopes of limiting global climate change to tolerable levels. The country is the world’s largest producer of carbon dioxide (CO2), accounting for 28% of global emissions, and its move may inspire other countries to follow suit. But observers warn that China faces daunting challenges in reaching its goals. Kicking its coal habit will be particularly hard.

“We aim to have CO2 emissions peak before 2030 and achieve carbon neutrality before 2060,” Chinese President Xi Jinping told the United Nations General Assembly via a video link on 22 September. That’s “a very significant and encouraging announcement,” says Josep Canadell, an earth system scientist at Australia’s Commonwealth Scientific and Industrial Research Organisation. He says the new targets “won’t likely let us to stop at 1.5° Celsius [of global warming],” the preferred target set in the 2015 Paris agreement. “But below 2° might still be consistent with [Xi’s] announcement.” China’s commitment also “ratchets up pressure on other major emitters” to set more ambitious targets “while further isolating the Trump administration in its climate myopia,” Vance Wagner of Energy Foundation China wrote in a piece published online by the nonprofit China Dialogue.

China had previously said its CO2 emissions would peak “around” 2030, a target most analysts considered within reach. But achieving carbon neutrality before 2060 will require drastically reducing the use of fossil fuels in transportation and electricity generation and offsetting any remaining emissions through carbon capture and storage or planting forests.

EU report about vanishing beaches was alarmist and wrong, scientists say

by Ben Webster, Oct 27  in TheTimes

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

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.

First-of-its-kind surface water Atlas brings together 35 years of satellite data

by EU Science Hub, Oct 2020

The Atlas provides a better understanding of the consequences climate change and human actions have for the planet’s surface water resources.

It is impossible to overstate the critical importance of water in our daily lives. Surface water bodies – including lakes, ponds and rivers – are particularly important as sources of water for domestic, industrial and agricultural use.

As the Earth’s surface water is intensely dynamic, our knowledge about where waterbodies can be found has not always been accurate. Waterbodies move, whole lakes dry up and new rivers and lakes form, which makes mapping these moving targets difficult.

Building on a project that combined thousands of years of computer time with millions of satellite images, the JRC’s Atlas of Global Surface Water Dynamics describes the important role that surface water plays for our planet’s climate and biodiversity, as well as virtually every aspect of our daily lives.

The Atlas documents the science behind a set of truly unique maps, which include time, and illustrates the changes in surface water resources over the past 35 years.

The scientists believe that the Atlas can improve our understanding of the consequences of climate change and human action on surface water resources, and that clearer understanding can help decision-makers to plan environmental actions and design effective policies aimed at the sustainable management of surface water resources.

Global Warming Wallops 20 Million Americans With Snow, Freezing Rain

by B. Lyman, Oct 27, 2020 in ClimateChangeDispatch

More than 20 million Americans are under some sort of winter weather watch, warning, or advisory from the Southwest through the Midwest as of Monday.

The Weather Channel has dubbed the storm “Winter Storm Billy” and said the storm will bring snow throughout parts of the Southern Rockies, the Central Plains, and Missouri.

From Arizona to Wisconsin, residents could see snowfall Monday, while those further south, like in Texas and Oklahoma, will see freezing rain and sleet, according to CNN.

Ice in Texas and Oklahoma is expected to accumulate roughly half an inch, which could cause dangerous travel conditions and knock power out, per the same article. Oklahoma City is under an Ice Storm Warning.

Temperatures in North Texas are roughly 25 degrees Fahrenheit below average. Texans living in the Texas Panhandle area could see one to two inches of snow during the area’s first Winter Storm Warning of the season, according to CBS Dallas-Ft. Worth.

While temperatures in Arizona won’t be as cold as some other states, some areas in the state could see a low of 46 degrees on Tuesday — the first temperature in the 40s since March, according to AZ Central.

Some areas of Colorado and New Mexico are expected to see two feet of snow, which comes as a bit of relief as wildfires continue to rage in Colorado’s Boulder and Larimer Counties, according to The Denver Channel. In Aguilar, Colorado, there were already 14 inches recorded from snowfall Sunday into Monday, per the same report.

Guardian Needlessly Alarmed By Late Freeze

by P. Homewood, Oct 27, 2020 in NotaLotofPeopleKnowThat

For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October.

The delayed annual freeze in the Laptev Sea has been caused by freakishly protracted warmth in northern Russia and the intrusion of Atlantic waters, say climate scientists who warn of possible knock-on effects across the polar region.

Ocean temperatures in the area recently climbed to more than 5C above average, following a record breaking heatwave and the unusually early decline of last winter’s sea ice.

The trapped heat takes a long time to dissipate into the atmosphere, even at this time of the year when the sun creeps above the horizon for little more than an hour or two each day.

Graphs of sea-ice extent in the Laptev Sea, which usually show a healthy seasonal pulse, appear to have flat-lined. As a result, there is a record amount of open sea in the Arctic.

“The lack of freeze-up so far this fall is unprecedented in the Siberian Arctic region,” said Zachary Labe, a postdoctoral researcher at Colorado State University. He says this is in line with the expected impact of human-driven climate change.

“2020 is another year that is consistent with a rapidly changing Arctic. Without a systematic reduction in greenhouse gases, the likelihood of our first ‘ice-free’ summer will continue to increase by the mid-21st century,’ he wrote in an email to the Guardian.

The warmer air temperature is not the only factor slowing the formation of ice. Climate change is also pushing more balmy Atlantic currents into the Arctic and breaking up the usual stratification between warm deep waters and the cool surface. This also makes it difficult for ice to form.

Science and politics

by Judith Curry, Oct 26, 2020 in WUWT

“I’m reaching out to scientists this week about the election. How do you feel about it? Which of the candidates has the best plan, for you, in science and technology?”

The above question was emailed to me today by a reporter.

My response:

I am not happy with either the Democratic or Republican plans for science in the U.S.  Both sides seem to want to use and misuse science as a club to further their political agendas.  The Republicans seem to prefer to ignore science, while the Democrats cherry pick science to further their political agendas.

Here is the long response,some text from something that I’m working on:

Dutch regulatory lawyer Lucas Bergkamp summarizes the challenge in this way. Science has become an instrument used by politicians and agencies to arm themselves with powerful arguments in complex value-laden debates. Scientists have let the politicians hijack the scientific enterprise. Both policy makers and scientists exploit scientific uncertainty to avoid debate on the relation between science and politics, facts and values. Armed with science, politicians are able to avoid accountability for decisions. Serious debate is avoided because politicized science has purged doubt and skepticism. Activist climate science makes use of a series of strategies and tactics to influence public opinion and politics. Bergkamp concludes that climate science itself has come under siege.

Scientization of policy is a response to intractable political conflicts that transforms the political issues into scientific ones. The rationale for scientization is the belief that science can act as a neutral arbiter of policy — if we could only determine the facts of a matter, the appropriate course of action would become clear. The problem is that science is neither neutral nor capable of answering political questions. The answers that science gives depend on what questions are asked, which inevitably involves value judgments. Science is not designed to answer questions about how the world ought to be, which is the work of politics.

Policy makers are culpable in the misuse of science for policy making by:

DENVER OBLITERATES ALL-TIME LOW TEMPERATURE RECORDS IN WEATHER BOOKS DATING BACK 148 YEARS

by Cap Allon, Oct 27, 2020 in Electroverse

The GRAND SOLAR MINIMUM has taken out multiple low temperature records in Denver, Colorado of late, as a weak and wavy “meridional” jet stream sends Arctic air anomalously-far south.

Denver has detailed weather books dating all the way back to 1872. One thing they reveal is that on each and every October day in those past 148 years, the thermometer has never failed to reach at least 18F… until yesterday, that is.

On Monday, October 26, the mercury struggled to a high of just 16F — a new record for the coldest October high temperature ever recorded in Denver.

Permian–Triassic mass extinction pulses driven by major marine carbon cycle perturbations

by Jurikova, H. et al., Oct 19, 2020 in NatureGeoscience

Abstract

The Permian/Triassic boundary approximately 251.9 million years ago marked the most severe environmental crisis identified in the geological record, which dictated the onwards course for the evolution of life. Magmatism from Siberian Traps is thought to have played an important role, but the causational trigger and its feedbacks are yet to be fully understood. Here we present a new boron-isotope-derived seawater pH record from fossil brachiopod shells deposited on the Tethys shelf that demonstrates a substantial decline in seawater pH coeval with the onset of the mass extinction in the latest Permian. Combined with carbon isotope data, our results are integrated in a geochemical model that resolves the carbon cycle dynamics as well as the ocean redox conditions and nitrogen isotope turnover. We find that the initial ocean acidification was intimately linked to a large pulse of carbon degassing from the Siberian sill intrusions. We unravel the consequences of the greenhouse effect on the marine environment, and show how elevated sea surface temperatures, export production and nutrient input driven by increased rates of chemical weathering gave rise to widespread deoxygenation and sporadic sulfide poisoning of the oceans in the earliest Triassic. Our findings enable us to assemble a consistent biogeochemical reconstruction of the mechanisms that resulted in the largest Phanerozoic mass extinction.

New Study Finds A Robust Link Between European Temperatures And Solar Activity Via AMO/NAO Modulation

by K. Richard, Oct 22, 2020 in NoTricksZone

European winter temperature variability is “dominated” by the North Atlantic Oscillation (NAO), which is, in turn, modulated by solar activity.

Even proponents of anthropogenic global warming (AGW) agree natural processes (AMO, NAO, ENSO, solar forcing, volcanism) drive temperature variability. But they insist the rising temperature trend is human-caused.

So if we don’t have a regional upward trend, is the non-warming natural or anthropogenic?

Lüdecke et al., 2020 find temperatures across Europe have been oscillating, not rising in linear fashion, for the last century. The timings of the temperature undulations correspond quite closely to natural ocean cycles (the NAO and AMO). The authors detail a non-linear and indirect solar activity impact on these ocean cycles, and ultimately to the European climate.

Why lockdown had little to no effect on global temperatures

by A.N. Archer & J.Weber, Oct 22, 2020 in Phys.Org

Countries across the world took unprecedented action in the first few months of 2020 to control the spread of COVID-19. At its peak, one-third of the world’s population was in lockdown. Around the world, car travel fell by 50%, the number of flights plummeted by 75% and industrial activity fell by around 35%.

With so many cars parked, airplanes grounded and factories closed, global carbon dioxide (CO₂) emissions fell by around 17% compared with the same period in 2019. But greenhouse gases such as CO₂ weren’t the only emissions to fall, and not all pollution heats the planet. Some of the industrial activities that shut down—particularly heavy industry, including steel and cement making—also produced aerosols, which are that linger in the atmosphere for weeks and reflect heat from the Sun.

Previous studies have suggested that if a lot of these industrial processes were to suddenly shut down, it would lead to short-term warming because the atmosphere would lose the reflective effect of aerosols. But as the lockdown cleared skies, temperatures didn’t rocket.

In new research, we show that lockdown had a negligible effect on global temperatures. So what really happened?

NSIDC: 2020 POLAR ICE DOING JUST FINE

by Cap Allon, Oct 24, 2020 in Electroverse

According to the latest October report from the National Snow and Ice Data Center (NSIDC), the ice locked at Earth’s poles is, overall, GROWING.

By volume, Antarctica contains 90% of Earth’s ice, and volume is a far better metric to use when judging the state of an ice sheet than sea ice extent. Extent is prone to wild and unpredictable fluctuations due to natural changes in ocean currents and wind patterns, etc–though these fluctuations are of a much lesser degree in Antarctica than in its northern cousin, the Arctic.

According to the latest NSIDC report, Antarctic sea ice extent reached a whopping 18.95 million square kilometers (7.32 million square miles) on September 28. Mid to late Sept would usually give us the year’s maximum extent, but given the favorable conditions in October, the maximum may well be higher. “As is typical this time of year, there are wide swings caused by winds and storms along the extensive ice edge,” writes the NSIDC.

Ice extent around Antarctica is now “well above the 1981 to 2020 median extent,” the NSIDC informs us. “Ice extent is above the median extent along a broad area off the Wilkes Land coast and western Ross Sea, near the median extent from the Amundsen Sea clockwise to the Weddell Sea and above the median north of Dronning Maud Land, Enderby Land, and the Cosmonaut Sea. The only major area of below the median extent is in the Indian Ocean sector near the Amery Ice Shelf and eastward.”

Ten fat polar bears filmed raiding a stalled Russian garbage truck

From the Siberian Times today (20 October) is a story with few facts but a fabulous video of six fat adults and four fat cubs as they set siege to a stalled open garbage truck in the Russian Arctic. It may have been filmed on Novaya Zemlya but that has not been confirmed.

Of course, Novaya Zemlya has had previous problems with bears habituated to garbage, most famously an extended incident in 2019 that was perversely blamed on climate change.

There were two families that I could see in the video: a female with two cubs-of-the-year and another with two year old cubs. All were in excellent condition, as were the other four adults. Novaya Zemlya, if indeed this is where the incident took place, is between the Barents and Kara Seas (see below):

Dubai builds first coal power plant despite pledging lowest carbon footprint in the world by 2050

by Independent, Oct 22, 2020

A new wonder is rising in the southern desert of Dubai against the backdrop of Persian Gulf beaches, but it’s not another skyscraper to grace the futuristic sheikhdom. Instead, it’s one of mankind’s oldest power sources gaining its own space on the oil-rich Arabian Peninsula — a coal-fired power plant

The construction of the $3.4 billion Hassyan plant in Dubai appears puzzling, as the United Arab Emirates hosts the headquarters of the International Renewable Energy Agency. It’s also building the peninsula’s first nuclear power plant and endlessly promotes its vast solar-power plant named after Dubai’s ruler. Dubai has also set the lofty goal of having the world’s lowest carbon footprint in the world by 2050 — something that would be impacted by burning coal.

The coal plant’s arrival comes as Gulf Arab nations remain among the world’s hungriest for energy and amid political concerns over the use of natural gas imported from abroad, concerns underscored by a yearslong dispute with gas-producer Qatar, which is boycotted by four Arab nations, including the UAE.

“Dubai was really saying we’re far too exposed on gas imports, those could be interrupted by all kinds of things, the cost is very high and so we have to do something else to diversify our fuel supply and bring down the total cost,” said Robin Mills, the CEO of Qamar Energy, a Dubai-based consulting company. “They got a very competitive offer on the coal plant … and so the decision was made.”

New Study: East Antarctica Was Up To 6°C Warmer Than Today During The Medieval Warm Period

by K. Richard, Oct 15, 2020 in NoTricksZone

As recently as 2000 to 1000 years ago, spanning the Roman to Medieval Warm Periods, East Antarctica was 5-6°C warmer than it is today. The consequent ice melt resulted in >60 meters higher water levels in East Antarctica’s lakes.

East Antarctica has been rapidly cooling in recent decades, with magnitudes reaching -0.7°C to -2.0°C per decade since the mid-1980s (Obryk et al., 2020).

A new study (Myers et al., 2020) reports that until about 15,000 years ago and throughout the Last Glacial Maximum, East Antarctica was 4-9°C colder than it is today.

Antarctica then abruptly warmed 15°C within centuries. From 12,000 to 6,000 years before present, East Antarctica was about 5°C warmer than it is today.

De Telegraaf Misled By UN Disaster Report Researcher

by P. Homewood, Oct 20, 2020 in NotaLotofPeopleKnowThat

You will all recall the latest UN report, which claimed there had been a massive rise in “reported disasters” in the last two decades, compared to the previous two.

The Dutch newspaper, De Telegraaf, published an article in response complaining that the UN were not comparing like with like, because many smaller disasters were simply never recorded in the past. They also published this reply from Joris van Loenhout, researcher at the Belgian Centre  for  Research on the Epidemiology of Disasters  (CRED):

“From about 1960-1970 onward, the completeness of the data is much greater, and the share of missing disasters much smaller. We are constantly working to improve completeness, and this is also happening for previous years and decades. For this reason, statements made in 2004 and 2006 are now somewhat outdated, as the completeness of the database has since improved,”

 I have now had time to analyse CRED’s database, EM-DAT, and have the figures to show that Loenhout has not been telling the truth.

Creepy Climate Conversations

by Donna Laframboise, Oct 21, 2020 in BigPicturesNews

Tony Thomas has a disturbing piece over at Quandrant.org, concerning an Australian organization allegedly run by child activists. It’s now urging kids to initiate creepy conversations with adults as a means of spreading climate propaganda.

Matters may not develop as expected, though. Because any adult who was around for the global cooling scare, who was told acid rain would wipe out the worlds forests, and that the hole in the ozone layer would induce widespread skin cancer has, in fact, heard it all before.

It’s interesting that the SchoolStrike4Climate.com website can’t stay on topic. Its front page tells us Australia was stolen from First Nation communities, and that “there can be no climate justice without first nations justice.” If you click the large button labelled: Black Lives Matter Resources, you’re taken to a 7-page Google document that similarly declares: “There is no climate justice without racial justice…”

These statements, call to mind 17-year-old Greta Thunberg’s assertion that “We can not have climate justice without gender equity.”

Climate justice. First Nations justice. Racial justice. Gender equity. What does this collection of causes tell us? That these young people aren’t rebels at all. Nor are they independent thinkers.

Rather than being sincere and passionate about a single issue they themselves have carefully investigated, these youngsters are merely hopping aboard the bandwagon known as fashionable left wing politics.

If you truly believed your future was imperiled, wouldn’t you keep on topic? Wouldn’t your anxiety focus your attention? Wouldn’t you pursue a single, realistic, achievable goal?

Instead, these high school students are being encouraged to believe that, by skipping school, they’ll convince the rest of us to do their bidding – not just about the climate, but with respect to other complicated, longstanding social issues. Everything will be transformed. Fixed to their satisfaction. All at the same time, no less.

Only a naive young person could imagine this to be remotely possible.

New Climate Report: Islands Not Losing Land, People To Sea-Level Rise

by J. Taylor, Oct 19, 2020 in ClimateChangeDispatch

A new study posted at ClimateAtAGlance.com documents that most small islands are growing, not losing land to sea-level rise, and island nations are attracting growing populations rather than shedding climate refugees.

The new climate summary drives a stake into the heart of alarmist assertions that climate change and rising seas are threatening island nations and their populations.

Objective measurements show that islands and atolls are growing in size, not disappearing under rising seas.

Rising seas bring sand and sediment, which build up coastal shorelines and are more than keeping pace with rising waters.

Also, coral, as living organisms growing near sea level, build up their height along with the rising sea.

For example, climate activists often claim the island nation of Tuvalu is shrinking due to rising seas and spawning climate refugees.

However, a recent peer-reviewed study found eight out of Tuvalu’s nine coral atolls have grown in size during recent decades, and three-fourths of Tuvalu’s 101 reef islands have similarly grown in size.

Also, Tuvalu’s population is consistently growing, not declining, with 20% more people living on Tuvalu now than 30 years ago. Tuvalu’s population has doubled since 1970.

Additional peer-reviewed studies (see here, here, and here) confirm the same processes are allowing – and will continue to allow – other Pacific islands to keep up with rising seas.

For example, 30 years ago, the Canberra Times claimed all 1196 islands that comprise the Maldives could be completely underwater by now.

Not only are all 1196 islands still there, but the Maldives population has doubled during the past 20 years.

People are flocking to the Maldives islands, not fleeing them. The Maldives are absorbing political refugees, not spawning climate refugees.

Is Mauna Loa Really The Best Location To Measure ‘Global’ CO2 Levels?

by K. Richard, Oct 19, 2020 in NoTricksZone

Highly anomalous terrain (an active volcano), 40 years of cooling temperatures, and a CO2 record that dramatically contrasts with fluctuating values from forests and meadows reaching 600-900 ppm all beg the question: Is Mauna Loa’s CO2 record globally representative?

Mauna Loa is the Earth’s largest land volcano. It has erupted over 3 dozen times since 1843, making this terrestrial landscape extremely unusual relative to the rest of the globe’s terrain. (Forests, in contrast, cover over 30% of the Earth’s  land surface.)

Mauna Loa has been thought to be the world’s best location to monitor global CO2 levels since 1958.

While Mauna Loa CO2 levels show a rise of 338 ppm to 415 ppm since 1980, Mauna Loa temperatures (HCN) show a cooling trend during this same time period. The only warming period in the last 65 years occurred between about 1975 and 1985.

Image Source: oz4caster

Forest CO2 fluctuations

As mentioned above, forests are orders of magnitude more terrestrially representative than the highly anomalous site of the Earth’s largest volcano.

In forests or tree-covered areas, CO2 rises from around 300 ppm in the warmth of the afternoon (~3 p.m.) to over 600 ppm before sunrise (~4 a.m.), when it is cooler (Fennici, 1986, Hamacher et al., 1994). This massive fluctuation occurs daily and CO2 values average out to be far higher than the Mauna Loa record suggests.

The future of the entire 350,000 km2 Great Barrier Reef hangs in the balance — as the coralapocalypse has wiped out 50% of the coral in just 25 years. Lordy! If only we’d built some off-shore wind farms on the reef to protect it! We could cover whole islands with solar panels? What are we thinking!

But as Peter Ridd points out, AIMS (The Australian Institute of Marine Science) surveys around 100 reefs every year — and for the last 35 years — and they find things are roughly the same. See the graph below.

Somehow Terry Hughes — and the Centre of Excellence for Integrated Coral Reef Studies — gets up to $4 million each year to report on the reef but won’t release the data behind the mass media campaign.

The ABC — which gets nearly $3 million dollars every single day — can’t even pick up the phone to interview AIMS or Peter Ridd and ask one hard question of Terry Hughes’ “Excellent” centre. (We all know why they had to put the word “excellence” in the title, it was the only way the word would ever be used to describe an activist group pretending to be scientists.)

And we all know that if anyone at James Cook University (JCU) has any doubts about the quality of the output from the “Excellent” centre they won’t be saying a word or they’ll get sacked like Peter Ridd did.

JCU — still supporting junk science and ignoring that other case of potential fraud?
