Greenland Temperature Data For 2018

by P. Homewood, April 24, 2019 in NotaLotOfPeopleKnowThat

The DMI has just published its Greenland Climate Data Collection for last year, and it is worth looking at the temperature data:

There are six stations with long records, Upernavik, Nuuk, Ilulissat, Qaqortoq, Narsarsuaq and Tasilaq.

…

Throughout Greenland we find that temperatures in the last two decades are little different to the 1920s to 60s.

The only exceptions were 2010 on the west coast sites, which was an unusually warm year, and 2016 on the east coast at Tasilaq, another warm year there.

Noticeably, last year was actually colder than the 1981-2010 average at all of the west and south coast stations.

The big Arctic Sea-Ice shift of 2007: Ice refuses to melt

by Javier, April 23, 2019 in WUWT

I have maintained since 2015 that in the 2006-2007 season the Arctic underwent a cyclical phase shift, and the rapid sea-ice melting observed over the previous decades ended. A few scientists predicted or explained this shift based on their study of multi-decadal oscillations (see bibliography). They were ignored by mainstream climatology and the press because the “anthropogenic” melting of the Arctic is one of the main selling points of the climate scare. See for example:

…

Year after year the data supports my view over the desperate scaremongers like Tamino. With the passing of time it is more and more difficult to defend the idea that Arctic melting is continuing, so alarmists keep changing the metric. First it was September sea-ice extent (SIE), then September sea-ice volume, and now annual average SIE. However, the reference measurements are September minimum SIE and March maximum SIE.

This article is more than a biannual update on the Arctic ice situation, as I will focus specifically on showing evidence for the trend change that took place in 2007. As 12 years have passed since the shift, the best way is to compare the 2007-2019 period with the previous 1994-2006 period of equal length to display the striking differences between both periods.

Solar variability manifestations in weather and climate characteristics

by Zherebtsov G.A. et al., April 2019 in J.Atm&SolarTerrestrialPhysics

Abstract

We discuss the issues of primary importance to understand the nature of climate changes in the 20th century and main physical processes responsible for these changes and present a physical model for the solar activity (SA) effect on climate characteristics. A key concept of this model is the heliogeophysical disturbance effect on the Earth climate system parameters driving the long-wave radiation flux moving away from the Earth out into space in high-latitude regions. We address the solar activity effect on the changes in the temperature of the atmosphere and of the World Ocean. The aa–index of the geomagnetic activity (GA) was used as an SA proxy index. We discuss the results of analyzing the regularities and peculiarities of the tropospheric and sea surface temperature (SST) responses to both separate heliogeophysical disturbances and long-term changes in solar and geomagnetic activity. The structure of the tropospheric and SST temperature responses was shown to feature a spatial time irregularity. We revealed the regions, where long-term SST changes are determined mainly by SA variations.

HAPPY EARTH DAY! WHEN WE CELEBRATE EVERY FAILED ALARMIST ECO-PREDICTION

by Nicolas Loris, April 22, 2019 in GWPF/BangorDailyNews

We should be thankful that the gloom-and-doom predictions made throughout the past several decades haven’t come true. Fear-mongering about explosive population growth, food crises and the imminent depletion of natural resources have been a staple of Earth Day events since 1970. And the common thread among them is that they’ve stirred up a lot more emotions than facts.

“By the year 2000, if present trends continue, we will be using up crude oil at such a rate … that there won’t be any more crude oil,” ecologist Kenneth Watt warned around the time of the first Earth Day event. “You’ll drive up to the pump and say, ‘Fill ’er up, buddy,’ and he’ll say, ‘I am very sorry, there isn’t any.’” Watt also warned of global cooling and nitrogen buildup rendering all of the planet’s land unusable.

Arctic Ice Gain Embarrasses Global Warming Scientists. 40-Year Meteorologist: “Don’t Be Surprised Over What Happens Next 10 -15 Years!

by P. Gosselin, April 21, 2019 in NoTricksZone

Yesterday I wrote here how some scientists misrepresent the observed data concerning Greenland ice melt in order to get the alarming results they want. There we see that Greenland has been melting, but recently much more slowly than what we are often led to believe.

Looking at the latest Greenland ice volume data from the Danish Meteorological Institute (DMI), we see that currently the ice volume is below normal, but well within the range of the past 17 years:

Isle de Jean Charles & Sea Level Rise

by P. Homewood, April 20, 2019 in NotaLotOfPeopleKKnowThat

The Isle de Jean Charles, Louisiana. It’s been largely submerged beneath the sea over the last 6 decades. The program gives the definite impression that the main reason for this inundation is sea level rise due to melting ice and thermal expansion of the oceans – driven by man-made climate change. Attenborough does mention oil extraction as a cause but his narrative is lost to the general tone of the messaging that this is a “climate catastrophe” and that the families driven from their homes in this part of Louisiana are some of the world’s first “climate refugees”. This is palpable bullshit.

An End… and a New Direction

by Tim Ball, April 20, 2019 in WUWT

I thought about making this my last article on climate for this or any other website except my own. I planned the action some time ago, but it was the recent headline in the Telegraph that triggered this penultimate move. It said, “Climate change is a risk investors can’t ignore: Black Rock latest to sound the alarm on environment.”

Climate change is not a risk factor. Current climate and climate changes are normal and well within the pattern of change over history, certainly the last 10,000 years. The world believes otherwise, despite efforts by me and others to make the correct information available.

This means that after 50 years (1968-2019) of trying to educate the public about the weather, global warming, and climate change I achieved little or no change in understanding, attitude, or most importantly, policy on the world stage. My attempts to counter the massive deception that began as human-caused global warming (AGW) and later shifted to human-caused climate change, fell short. The deception is now what people accept, although they don’t necessarily believe. Because of that it is now the underlying reason for all policy on energy and environment that are the mainstay of these business-world views, indeed all views.

Native American Wisdom on Polar bears and Kappiananngittuq:

by Jim Steele, April 19, 2019 in WUWT

In 2010 Nunavut’s Minister of Environment Daniel Shewchuk wrote, “Inuit hunters have a close relationship with the land and wildlife. They have observed that the overall population of polar bears in Nunavut is not declining as some suggest, but rather is thriving. No known environmental or other factors are currently posing a significant or immediate threat to polar bears overall. Furthermore, Inuit knowledge and science corroborate that the species can and will adapt to changing and severe climatic conditions, as it has done for centuries.”

The Inuit truly practice the concept of “it takes a village”. Hunters sit down in kappiananngittuq and respectfully share their observations of wildlife and their movements. Kappiananngittuq is the Inuit word for a “safe place to discuss”. Based on community discussions, Inuit have steadfastly claimed it is “The Time of the Most Polar Bears”. Overhunting has been one of the world’s greatest threats to wildlife. And the growing number of polar bears is testimony to wise hunting regulations now honored by the Inuit.

CO2’s Influence Was 0.006 W/m² Per Decade During The Last Deglaciation. And This Melted Ice Sheets How?

by K. Richard, April 18, 2019 in NoTricksZone

According to the calculations of Dr. James Hansen, the radiative influence derived from the increase in CO2 during the last deglaciation was so negligible that it equated to “a third of energy required to power a honey bee in flight” (Ellis and Palmer, 2016).

Vilifying People Who Question Global Warming Is Anti-Science

by Todd Royal, April 17, 2019 in ClimateChangeDispatch

When pollsters realized that the public and elected officials weren’t buying global warming as a concept or policy, in a brilliant political move, they came up with the phrase “climate change.”

This helped sell the theory of man-made global warming. Weather is politicized, and computer models are only predictions that have been used as pawns in elections and justifying increased government budgets.

The global warming/climate change (GWCC) narrative has made Al Gore a rich man peddling unrealized fear.

In January 2012, sixteen eminent scientists published an article in the Wall Street Journal, titled, “No Need to Panic About Global Warming.” If mankind is causing global warming, then how do you explain this?

Today’s CO2 concentrations worldwide average about 380 parts per million. This level of CO2 concentration is trivial compared with the concentrations during earlier geologic periods.

For example, 460 million years ago, during the Ordovician Period, CO2 concentrations were 4,400 ppm, and temperatures then were about the same as they are today. With such high levels of CO2 the Earth should have been boiling.

It seems more reasonable to be agnostic based upon this fact:

Biofuels: a long-standing illusion

by Prof. S. Furfari, April 4, 2019 in EuropeanScientist

The idea of replacing petroleum products with alternative fuels produced from agriculture dates back to the 1973 and 1979 oil crises. But apart from the development of bioethanol from cane sugar in Brazil, the idea had not come to fruition because it was not economically viable. It was the frenzy for some kind of sustainable development in the mid-2000s, combined with a perfect storm of realities, that led to the emergence of a political interest in biofuels.

El Niño Conditions Persist in the Pacific Ocean

by A. Watts, April 16, 2019 in WUWT

An El Niño that began to form last fall has matured and is now fully entrenched across the Pacific Ocean. Changes in sea surface temperatures (SSTs) brought about by an El Niño affect the atmosphere, resulting in distinctive changes in the rainfall pattern across the Pacific Basin. These changes show up as anomalies or deviations in NASA’s analysis of climatological rainfall.

…

As with a traditional El Niño, the effects from a Central Pacific El Niño can still spread to the U.S. Also, clearly visible in the NASA-generated monthly average rainfall was an area of heavy rain over the southeast coast of Africa associated with the passage of Cyclone Idai, which devastated the region with torrential flooding.

40-Year Meteorologist Says Public “Being Fed Bill Of Goods” By Climate Alarmists On Hurricanes, Tornadoes

At the latest Saturday Summary at Weatherbell Analytics, Joe Bastardi, a well-known 40-year veteran of meteorology, looks at tornadoes and hurricanes.

Although many meteorologists and climatologists confirm that there is no data suggesting global warming is causing more frequent and intense tornado and hurricane activity, there is a small but influential alarmist group who claim otherwise.

We now know how insects and bacteria control ice

by University of Utah, April 14, 2019 in WUWT

Proteins help organisms form or inhibit ice crystals

Contrary to what you may have been taught, water doesn’t always freeze to ice at 32 degrees F (zero degrees C). Knowing, or controlling, at what temperature water will freeze (starting with a process called nucleation) is critically important to answering questions such as whether or not there will be enough snow on the ski slopes or whether or not it will rain tomorrow.

Nature has come up with ways to control the formation of ice, though, and in a paper published today in the Journal of the American Chemical Society University of Utah professor Valeria Molinero and her colleagues show how key proteins produced in bacteria and insects can either promote or inhibit the formation of ice, based on their length and their ability to team up to form large ice-binding surfaces. The results have wide application, particularly in understanding precipitation in clouds.

“We’re now able to predict the temperature at which the bacterium is going to nucleate ice depending on how many ice-nucleating proteins it has,” Molinero says, “and we’re able to predict the temperature at which the antifreeze proteins, which are very small and typically don’t work at very low temperatures, can nucleate ice.”

Predicting heat waves? Look half a world away

University of California – Davis, April 12, 2019 in ScienceDaily

When heavy rain falls over the Indian Ocean and Southeast Asia and the eastern Pacific Ocean, it is a good indicator that temperatures in central California will reach 100°F in four to 16 days, according to a collaborative research team from the University of California, Davis, and the Asia-Pacific Economic Cooperation (APEC) Climate Center in Busan, South Korea.

The results were published in Advances in Atmospheric Scienceson April 12.

FROM PREDICTION TO PROTECTION

Heat waves are common in the Central California Valley, a 50-mile-wide oval of land that runs 450 miles from just north of Los Angeles up to Redding. The valley is home to half of the nation’s tree fruit and nut crops, as well as extensive dairy production, and heat waves can wreak havoc on agricultural production. The dairy industry had a heat wave-induced economic loss of about $1 billion in 2006, for instance. The ability to predict heat waves and understand what causes them could inform protective measures against damage.

Flashback 2008 – Climate change study predicts refugees fleeing into Antarctica

by P. Homewood, April 13, 2019 in NotaLotofPeopleKnowThat

Climate change will force refugees to move to Antarctica by 2030, researchers have predicted.

Among future scenarios are the Olympics being held in cyberspace and central Australia being abandoned, according to the think tank report.

Forum for the Future, a research body committed to sustainable development, said they wanted to stir debate about how to avert the worst effects of global warming by presenting a radical set of ‘possible futures’.
There will be a shift towards greater energy efficiency, where desalination plants will run on solar power will turn the Sahara green.

Refugees are expected to move to Antarctica because of the rising temperatures that will see the population of the continent increase to 3.5 million people by 2040.

As the world fails to act on climate change, researchers predict that global trade will collapse as oil prices break through $400 a barrel and electrical appliances will get automatically turned off when households exceed energy quotas.

SCE fête son premier anniversaire avec 70 articles, près de 300 commentaires publiés (questions et réponses) et plus de 260 000 visiteurs.

Ce succès, il le doit à ses lecteurs car nous pensons qu’ils y trouvent une analyse critique des thèmes qui ne cessent d’occuper le devant de la scène médiatique nous montrant une dérive climatique tous azimuts symboliquement illustrée par la marche des lycéens, cautionnée par le monde politique et hélas aussi scientifique.

Notre site ne veut pas attiser la polémique mais bien susciter le débat car notre ligne directrice est l’argumentation et la discussion constructive en dehors de tous propos haineux, injurieux ou fantaisistes. Pas besoin de faire une dessin sur ce genre de propos que nous nous appliquons à ‘filtrer’ pour éviter les dérives qui sont monnaie courante sur les réseaux sociaux, mais finalement seulement moins de 5 % des commentaires sont refusés. Les commentaires argumentés qui contestent notre analyse sont bien entendu aussi publiés et c’est ainsi l’occasion de développer un débat serein, de mise au point réciproque. Tout le monde y gagne en clarté et compréhension. Nous ne prétendons pas détenir la vérité mais nos compétences nous permettent de discuter des problèmes climatiques et souvent de fournir un autre point de vue que celui relayé dans les médias.

L’hystérie climatique, vous l’aurez remarqué est hors norme, elle a récemment atteint des sommets que personne n’avait imaginé il y a seulement quelques années, et le ‘politiquement correct’ est devenu la règle de base pour qui ne veut pas d’ennuis. Combien de lycéens, de politiques, parfois même de scientifiques ont-ils lu les rapports du GIEC ? Connaissent-ils seulement les concentrations actuelle et passées du CO2, la composition de l’atmosphère… ? On peut en douter.

Why California burns — its forests have too many trees

by T.M. Bonnicksen, November 12, 2018 in San FranciscoChronicle

The reason wildfires are burning California with unprecedented ferocity this year is because our public forests are so thick. It is our fault. We don’t manage our forests, we just let them grow. That is the simple truth. However, it is easier to deny the truth and blame a warming climate instead of admitting our guilt and taking action to prevent wildfires.

Hot, dry weather doesn’t cause catastrophic wildfires. It only makes them worse. In order for any fire to burn, it must have fuel. To spread wildly, it must have abundant fuel. Efforts in the 20th century to prevent fire and preserve forests have been too successful — they have disrupted the ecological balance and allowed more and more trees to grow.

Skeptic German Geologist Interview Goes Viral: Greta Demos “Emotional, Not Based On Fact”…”Selective Media”

by P. Gosselin, April 12, 2019 in NoTricksZone

German climate skepticism may have awakened, and ironically it may in large part be an unintended consequence of the “Greta demonstrations”. Germans may be finally getting fed up with the hysteria that has emptied out schools and turned into an ambush on their industrial jobs.

German geologist Dr. Sebastian Lüning, who together with Prof. Fritz Vahrenholt runs German climate skeptic site Die kalte Sonne, was recently interviewed by the conservative Junge Freiheit TV in Berlin (In German).

While the mainstream media focus almost exclusively on the ultra-alarmist climate scenarios, Lüning takes a far more moderate, non-alarmist view of climate and  man’s impact on it.

In Lüning’s view, natural factors play an as big, or even bigger. role on climate than humans do.

Recent warming “not unusual”

In the interview, Lüning explains how the assumptions made by the CO2 alarmists fall apart when tested against the observations of the past. The experienced German geologist explains why the modern 20th century warming is nothing unusual and that the same has already occurred numerous times over the past 10,000 years.

Start of industrialization coincided with end of Little Ice Age

One problem, Lüning says, is that scientists like to begin their temperature charts right before industrialization began in earnest, which happens to coincide near the temperature low point of the Holocene. He says that the term “pre-industrial” has been the source of “lots of confusion”.

2019 ENSO forecast

by  J. Curry and J. Johnstone, April 9, 2019 in WUWT

CFAN’s 2019 ENSO forecast is for a transition away from El Niño conditions as the summer progresses. The forecast for Sept-Oct-Nov 2019 calls for 60% probability of ENSO neutral conditions, with 40% probability of weak El Niño conditions. – Forecast issued 3/25/19

Introduction

CFAN’s early season ENSO forecast is motivated by preparing our seasonal forecast for Atlantic hurricane activity. ENSO forecasts made in spring have traditionally had very low skill owing to the ENSO ‘spring predictability barrier.’

During fall 2018, there was warming in the Central Equatorial Pacific, leading to a weak El Niño Modoki pattern, which impacted the latter part of the Atlantic hurricane season. This transitioned to a weak (conventional) El Niño in February 2019 and the atmospheric anomalies became more consistent with a conventional El Niño pattern.

NOAA’s latest forecast: Weak El Niño conditions are likely to continue through the Northern Hemisphere spring 2019 (~80% chance) and summer (~60% chance).

CFAN’s ENSO forecast analysis is guided by the ECMWF SEAS5 seasonal forecast system and a newly developed statistical forecast scheme based on global climate dynamics analysis.
