Polar Bear Dies, National Geographic Lies

by Donna Laframboise, August 3,  2018 in BigPictureNews


SPOTLIGHT: The iconic magazine is now a purveyor of propaganda.

BIG PICTURE: On her PolarBearScience.com blog last week, zoologist Susan Crockford called our attention to a startling admission over at National Geographic. It acknowledges publishing fake news. Or, as it more delicately puts it, we “went too far in drawing a definitive connection between climate change and a particular starving polar bear.”

An “Editor’s Note” explains the magazine added a wholly misleading caption to a video of an emaciated polar bear filmed last August. When it published this video on its website in December, National Geographic declared: “This is what climate change looks like.”

Actually, this is what dishonesty looks like. Neither the magazine nor the person who did the filming knew anything about that bear. It might have been stricken with disease. It might have sustained an injury that impeded its ability to hunt. As the Editor’s Note now admits: “there is no way to know for certain why this bear was on the verge of death.”

A Geological Perspective of Wildfires

by David Middleton, July 31, 1018 in WUWT


This post was inspired by Anthony Watts’ recent post about wildfires and their unwillingness to cooperate with the Gorebal Warming narrative.

A Geological Perspective of Wildfires

The Fire Window

Geological evidence for ancient wildfires generally consists of sedimentary charcoal deposits (inertinite).  Fossil charcoal is also a key factor in understanding the evolution of Earth’s atmosphere, particularly oxygen content.  The first clear evidence of fire is in the Late Silurian.

Meat, Dairy Industry Surpass Big Oil As World’s Biggest Polluters

by P. Homewood, July 31, 2018 in NotaLotofPeoppleKnowThat


Within the next few decades, Big Meat and Big Dairy could surpass Big Oil as the world’s biggest climate polluters, a new study by non-profit GRAIN and the Institute for Agriculture and Trade Policy (IATP) showed on Wednesday.

The world’s biggest animal protein producers could soon surpass ExxonMobil, Shell, and BP as the largest contributors to climate pollution, according to the study.

IATP and GRAIN jointly published the study that quantifies emissions from 35 of the world’s largest meat and dairy companies and reviews their plans to fight climate change.

The report found out that the five largest meat and dairy corporations combined – JBS, Tyson, Cargill, Dairy Farmers of America, and Fonterra – are already responsible for more annual greenhouse gas emissions than ExxonMobil, Shell, or BP. According to one figure in the report, the combined emissions of the top five companies are on par with those of Exxon and significantly higher than those of Shell or BP.

The truth behind the Baffin Bay starving polar bear video is worse than we thought

by P. Homewood, July 263, 2018 in NotaLotofPeopleKnowThat


Remember that video of an emaciated Baffin Island polar bear that went viral last December? In an unexpected follow-up (“Starving-Polar-Bear Photographer Recalls What Went Wrong“; National Geographic, August 2018 issue), photographer Cristina Mittermeier makes some astonishing admissions that might just make you sick.

Susan Crockford uncovers the truth behind that “starving polar bear video”

La terrible canicule de l’été 1911 qui provoqua 40 000 morts

by Pierre Bienvault, 22 juin 2017 in LaCroix


Encore dans toutes les mémoires, la canicule de 2003 et ses 15 000 morts n’a pas été la plus meurtrière de la France du XXe siècle.

 Il faudra marquer cette année 1911 d’une croix noire. » Voilà ce qu’écrivait, à la fin de l’été, un médecin du département de la Seine inférieure. À l’évidence traumatisé par les conséquences de la terrible vague de chaleur qui frappa alors, de juillet à septembre, toute l’Europe mais surtout la France et la Belgique. « Pendant la longue période de chaleur, la mort n’a cessé de faucher les tout-petits élevés au biberon », ajoutera ce médecin.

Une canicule de juillet à septembre

Encore dans toutes les mémoires, la canicule de 2003 et ses 15 000 morts n’a pas été la plus meurtrière en France. C’est ce que rappelait Catherine Rollet dans un article (1) paru en 2010. Cette historienne et démographe, décédée en décembre 2016, y racontait la dramatique canicule de l’été 1911.

How the Little Ice Age affected South American climate

by Fundação de Amparo à Pesquisa do Estado de São Paulo, July 24, 2018 in ScienceDaily


A new study published in Geophysical Research Journal shows that the so-called Little Ice Age — a period stretching from 1500 to 1850 in which mean temperatures in the northern hemisphere were considerably lower than at present — exerted effects on the climate of South America.

Based on an analysis of speleothems (cave formations) in the Brazilian states of Mato Grosso do Sul and Goiás, the study revealed that in the seventeenth and eighteenth centuries, the climate of southwestern Brazil was wetter than it is now, for example, while that of the country’s Northeast region was drier.

The same Brazilian cave records showed that the climate was drier in Brazil between 900 and 1100, during a period known as the Medieval Climate Anomaly (MCA), when the northern hemisphere’s climate was warmer than it is now.

 

Why we’re winning: WUWT gets more page views than the last two remaining government websites on climate

by Anthony Watts, July 17, 2018 in WUWT


(…)

While NBC News might think that 68,000 page views per month is impressive, in comparison to our regular daily traffic on WUWT, it pales in comparison. For example, here is a screencap from my WordPress dashboard from yesterday, July 16th, which was a fairly typical summer day for WUWT. Note that it shows 92,467 page views in one day.

What’s most interesting is that while there’s been a slow, almost imperceptible increase in the phrase “climate change”, the search phrase “global warming” is getting far less use than it did when data was first collected, back in 2004. Right now, both “climate change”, and “global warming” have low interests.

Chart of the week: The US is the leader in CO2 emissions reduction

Sound waves reveal diamond cache deep in Earth’s interior

by Jennifer Chu, July 16 in MITNews


There may be more than a quadrillion tons of diamond hidden in the Earth’s interior, according to a new study from MIT and other universities. But the new results are unlikely to set off a diamond rush. The scientists estimate the precious minerals are buried more than 100 miles below the surface, far deeper than any drilling expedition has ever reached.

The ultradeep cache may be scattered within cratonic roots — the oldest and most immovable sections of rock that lie beneath the center of most continental tectonic plates. Shaped like inverted mountains, cratons can stretch as deep as 200 miles through the Earth’s crust and into its mantle; geologists refer to their deepest sections as “roots.”

In the new study, scientists estimate that cratonic roots may contain 1 to 2 percent diamond. Considering the total volume of cratonic roots in the Earth, the team figures that about a quadrillion (1016) tons of diamond are scattered within these ancient rocks, 90 to 150 miles below the surface.

L’hydrogène géologique ou hydrogène naturel : Etat de la question

by A. Préat, 16 juillet 2018 in ScienceClimatEnergie


’hydrogène, un gaz peu abondant…
L’ hydrogène n’est présent qu’à concurrence de 1 ppm ( = une ‘partie par million’, soit 0,0001%) dans l’atmosphère : autant dire que c’est presque rien. D’où vient-il ? Peut-on en produire de grandes quantités à partir de ressources naturelles (géologie) ou artificielles (chimie) ? Autant de questions que de plus en plus d’industriels, de scientifiques, de politiques et de citoyens (?) se posent pour faire face à ce qu’il est convenu d’appeler la transition énergétique tant à l’ordre du jour, à raison ou à tort, là n’est pas l’objet de cet article. Comme nous le verrons par la suite, l’exploitation directe de l’hydrogène naturel n’est pas encore rentable et il faudra sans doute le produire à partir d’une autre source d’énergie, car il n’est pas lui-même une source d’énergie, mais au contraire un simple vecteur d’énergie.A l’heure actuelle il n’est donc pas exploité à une échelle suffisante en raison des contraintes géologiques et économiques, et il faut le synthétiser [1]. C’est ce que réalise aujourd’hui l’industrie principalement en vue de la fabrication de l’ammoniac pour les engrais ou des plastiques.

Diesel cars are still the most sensible option for long journeys despite pledge to wipe vehicles from roads by 2040, says transport secretary

by James Salmon, July 9, 2018 in DailyMail


Diesel cars may still be the most sensible option for many families who drive long distances, the transport secretary Chris Grayling said yesterday.

Despite a pledge to see the end of petrol and diesel vehicles on UK roads by 2040, Mr Grayling said new diesels were not destined for the scrapheap just yet.

He said: ‘If you are doing long distances on the motorway, maybe the new generation of diesel engines are the right option for now.

‘The Earth has a fever’ – the only solution is 14 billion air conditioners

by University of Birmingham, July 10, 2018 in WUWT


According to the report, if we are to take cooling demand seriously, the key stages to move towards a solution for cooling demand are:

  • Reducing the energy required for cooling: getting industry to adopt high efficiency cooling technologies and using maintenance to deliver optimum performance.

  • Reducing the need for cooling through better building design

  • Systems level thinking across built environment and transport

  • Harnessing waste resources: ‘wrong time’ renewables; waste cold; and waste heat.

  • Considering the strategies and skills required for installing appliances and maintaining them in order to maximise efficiency and reduce energy demand

  • Creating a model for delivery of affordable cooling to those in rural and urban communities based on the energy needs of local requirements, rather than imposing a ‘one size fits all’ approach

Ocean Temperature – Part 1

by Irek Zawadzki, July 10, 2018 in SkepticalScience


How have we measured the temperature of the ocean’s upper layer in the last 150 years? How does understanding physical processes and observational errors help to standardise climate data and understand climate change?

Sea surface temperature (SST) is also one of the climate indices with the longest histories of direct measurements. Because ocean makes up about 70% of the total Earth’s surface, changes in the temperature of its surface are a key factor for determining the global temperature of the planet’s surface.

Why Are We Doing This? A Trove Of New Research Documents The Folly Of Renewable Energy Promotion

by K. Richard, July 9, 2018 in NoTricksZone


The advocacy for widespread growth in renewable energy (especially wind, solar, and biomass) usage has increasingly become the clarion call of the anthropogenic global warming (AGW) movement.  And yet more and more published research documents the adverse effects of relying on renewables.

Over the course of the last year, at least 30 papers have been published in the peer-reviewed scientific literature detailing the fatuity of promoting renewable energy as a long-term “fix” for climate change mitigation.  A categorized list of these papers is provided below.

Quiet Sun: More than 3 months without a sunspot

by Dr Carlo Tesla, July 2, 2018 in A. Watts, WUWT


What if the worst is to come?” – Dr Carlo Testa.

2 July 2018 – “The Belgian department of solar physics research (SIDC) says we are about to touch 100; that is, a hundred days in which we do not see spots on our sun,” says Italian meteorologist Dr Carlo Testa.

During a time of  few or no sunspots (a solar minimum) the Sun emits less energy than usual, says Dr Testa. “According to some scholars this situation could lead to climatic upheavals.”

Suffice it to recall, says Testa, that between 1645 and 1715 the most significant solar minimum of history, the Little Ice Age, occurred, bringing years and years marked by very strict winters that lasted until June. (…)

Rapid 3D analysis of rockfalls in Yosemite

by Geological Society of America, June 28, 2018 in ScienceDaily


On 27 and 28 September 2017, eight large rockfalls occurred from the southeast face of El Capitan. These rockfalls resulted in one fatality and two serious injuries, and spurred a complicated rescue and temporary closure of the main road exiting Yosemite Valley. In order to manage these challenging events, the National Park Service (NPS) had a critical, immediate need for quantitative information about the sequence of rockfalls and the potential for additional activity.

Using new “structure-from-motion” photogrammetry techniques in conjunction with baseline laser-scanning data, scientists from the NPS, the U.S. Geological Survey, and the University of Lausanne, Switzerland rapidly analyzed these rockfalls. By comparing 3-dimensional (3D) models of the cliff before, during, and after the rockfalls, the researchers were able to pinpoint the exact locations, dimensions, and volumes of the rockfalls, along with the spatial and temporal pattern of their progression up the cliff.

Thirty Years On, How Well Do Global Warming Predictions Stand Up?

by P. Michaels and R. Maue, June 21, 2018  in WSJ


James Hansen issued dire warnings in the summer of 1988. Today earth is only modestly warmer.

What about Mr. Hansen’s other claims? Outside the warming models, his only explicit claim in the testimony was that the late ’80s and ’90s would see “greater than average warming in the southeast U.S. and the Midwest.” No such spike has been measured in these regions.

As observed temperatures diverged over the years from his predictions, Mr. Hansen doubled down. In a 2007 case on auto emissions, he stated in his deposition that most of Greenland’s ice would soon melt, raising sea levels 23 feet over the course of 100 years. Subsequent research published in Nature magazine on the history of Greenland’s ice cap demonstrated this to be impossible.

New Report: Recycling Plastic Is Making Ocean Litter Worse

by GWPF, June 28, 2018


* Most of the plastic waste comes from just a few countries, mostly in Asia and Africa.
* 25% is “leakage” from Asian waste management processes — the rest is waste that has never been collected, but is simply thrown into rivers.
* But European countries ship inject huge quantities of waste into Asian waste management streams, ostensibly for recycling. As much as 20% — millions of tons every year — ends up in the oceans and will continue to do so.
* Since the Chinese banned waste imports at the start of the year, shipments have been diverted to other Asian countries with even weaker environmental controls (Figure 1).
* EU recycling is therefore a major contributor to marine waste and increasing recycling will therefore simply increase marine litter.
