Opinion: New facts have emerged from the filmmaker behind the cruel and deliberate exploitation of a dying bear in quest to advance climate change agenda.
It was tragedy porn meant to provoke a visceral response — the gut-wrenching video of an emaciated polar bear struggling to drag himself across a snowless Canadian landscape made billions of people groan in anguish. Taken in August 2017 by biologist Paul Nicklen, a co-founder of the Canadian non-profit SeaLegacy, the video was posted on Instagram in December 2017, stating “This is what starvation looks like” as part of a discussion about climate change.

A no-assumptions look at the global warming evidence helps clarify the possibilities.
The planet’s surface has been warming since the depths of the Little Ice Age, and particularly since ~ 1850 AD. The surface temperature record, however incomplete or uncertain, reflects this warming. Hypotheses about why the warming is taking place can be grouped into three general categories:
- The energy input is increasing. This is the basis of the variable solar output hypothesis.
- The energy output is decreasing. This is the basis of the greenhouse gases hypothesis.
- The transfer of heat within the system is changing. This is the basis of some hypotheses for a reduced vertical exchange in the ocean, or for changes in the oceanic currents that redistribute the heat.
A combination of these categories cannot be ruled out.
Whatever causes the temperature change must necessarily affect its rate of change, the velocity at which temperature changes over time, measured in °C/decade. A velocity that varies continuously and can be positive (warming) or negative (cooling).

In June of this year, Howard Dewhirst, a fellow of The Geological Society (London), wrote a letter to the President of the Society voicing the concern of 33 current and former fellows of the society, as well as other concerned geoscientists, that the Society’s position on climate change is outdated and one-sided. As of this writing, receipt of the letter has been acknowledged, but no reply has been received. Given the long period of time, Howard has sent a second letter to the Society, it is reproduced below.
We understand that the council is reviewing the The Geological Society’s 2010 and 2013 position papers on climate change which was the subject of the letter we wrote to the society in early June. We also understand that despite the clear interest amongst Fellows – and other scientists, that the society will not be publishing further letters until the new position paper has been agreed. If true, we (the contributors to the first letter) think this is unfortunate, as now would be the very time to solicit informed opinion from Fellows and others as there clearly is not a consensus. …

Remember this? The ill-fated “Spirit of Mawson” expedition to Antarctica (in the Akademik Shokalskiy) that set out to bring attention to “global warming” only to be trapped in ice?
It’s deja vu all over again. (with h/t to Yogi Berra)

Through the analysis of samples, Broadley and his team tried to determine the composition of the lithosphere. They found that before the Siberian Flood Basalts took place, the Siberian lithosphere was heavily loaded with chlorine, bromine, and iodine, all chemical elements from the halogen group. However, these elements seem to have disappeared after the volcanic eruption.
“We concluded that the large reservoir of halogens that was stored in the Siberian lithosphere was sent into the earth’s atmosphere during the volcanic explosion, effectively destroying the ozone layer at the time and contributing to the mass extinction,” Broadley said.

- • We present a carbon cycle with an uptake proportional to the CO2 concentration.
- • Temperature dependent natural emission and absorption rates are considered.
- • The average residence time of CO2 in the atmosphere is found to be 4 years.
- • Paleoclimatic CO2 variations and the actual CO2 growth rate are well reproduced.
- • Human emissions only contribute 15 % to the CO2 increase over the Industrial Era.

A 2017 peer-reviewed paper authored by physicist Dr. Hermann Harde drew considerable response upon its publication in the journal Global and Planetary Change.
Harde’s conclusion that less than 15% of the increase in CO2 concentration since the 19th century could be attributed to anthropogenic emissions was deemed unacceptable by gatekeepers of the anthropogenic global warming (AGW) viewpoint.
A critical reply to the paper was consequently published, but it included assumptive errors and misrepresentations of the original points …

Merkel says EU should meet existing emissions aims, not set new ones
A proliferation of extreme weather events around the world provides ample evidence that climate change is a reality, German Chancellor Angela Merkel said on Sunday, but she rejected calls for more ambitious climate protection goals.
But Merkel said such calls, most recently from the European Commission’s climate chief Miguel Arias Canete, for swifter cuts to harmful carbon dioxide emissions would be counterproductive, adding that setting new goals made little sense when European countries were already struggling to meet their cuts targets.

Note: Please read Part 1 before reading this — this is a continuation of that essay (a rather long continuation….).
Readers will have heard the line “multiple lines of evidence” attached to the attribution of anthropogenic causes. However, that phrase is used only once in AR5 SPM as “Multiple lines of evidence indicate a strong, consistent, almost linear relationship between cumulative CO2 emissions and projected global temperature change to the year 2100….” I’m sure I don’t need to point out that there is never ever evidence about the future…..They do not claim in the Summary for Policy Makers that there are multiple lines of evidence for the attribution statement that apply to the past-to-present.

The Sun as climate driver is repeatedly discussed in the literature but proofs are often weak. In order to elucidate the solar influence, we have used a large number of temperature proxies worldwide to construct a global temperature mean G7 over the last 2000 years. The Fourier spectrum of G7 shows the strongest components as ~1000-, ~460-, and ~190 – year periods whereas other cycles of the individual proxies are considerably weaker. The G7 temperature extrema coincide with the Roman, medieval, and present optima as well as the well-known minimum of AD 1450 during the Little Ice Age. We have constructed by reverse Fourier transform a representation of G7 using only these three sine functions, which shows a remarkable Pearson correlation of 0.84 with the 31-year running average of G7. The three cycles are also found dominant in the production rates of the solar-induced cosmogenic nuclides 14C and 10Be, most strongly in the ~190 – year period being known as the De Vries/Suess cycle. By wavelet analysis, a new proof has been provided that at least the ~190-year climate cycle has a solar origin.

Why do ice ages occur? Surprisingly, even after many decades of paleoclimatic research we simply do not know for sure. Most scientists will agree that ice age cycles have something to do with precession: the slow wobble of the axis of the Earth. The ancient Egyptians and Greeks knew of precession and called it the Great Year, because it gives warm and cool seasons over its approximate 23,000-year cycle. But there is a problem with invoking the Great Year as the regulator of ice ages, because we should really get an interglacial warming every 23,000 years or so. And we don’t – they only happen every fourth or fifth Great Year.
But why should the global climate give a selective response to orbital warming and cooling? (Called ‘forcing’ in the climate trade.) This is one of the great unknowns of modern science.

I have often been asked “Why do you deny climate change?” I am always stumped by the question. It is rather like being asked “Why do you torture innocent animals?” The questioner is not merely asking for information, they are always making an accusation — an accusation that they consider very serious and a threat to themselves and others.
The reason it stumps me is that, as you have guessed already, I do not deny climate change (and I do not torture innocent animals — nor even guilty ones). And there is nothing about me or my behavior, present or past, that I am aware of, that would lead any reasonable person to think such a thing of me.
I am thoroughly guilty though of being very skeptical of what is generally referred to as the Climate Consensus — usually said to be represented by the latest reports and policy recommendations put out by the Intergovernmental Panel on Climate Change (IPCC) and its supporters; political, ideological and scientific. I suppose it is this that leads to the false accusation of “denying climate change”.
And there is the crux of the matter — it is something in the mind of the accuser, not any action of the accused, which leads to the false accusation.

The findings highlight the extent to which humans are impacting one of the world’s major ecosystems — the Miombo woodlands, which cover 2.5 million square kilometres, across countries including Angola, Zambia, Tanzania and Mozambique.
At the same time, however, the growing number of trees in remote parts of these woodlands is helping to offset the emissions, researchers say.
The study is the first to provide an in-depth analysis of areas gaining carbon while also losing it through degradation — a process where some, but not all, trees are removed, usually as a result of logging and fire.

As the Arctic summer ice melt approaches its peak, we can say with high certainty that this year’s ice melt will extend the trend of a rebounding Arctic ice mass by another year.
Arctic summer sea ice now growing 12 years
Our Japanese skeptic blogger and good friend Kirye reports using the data from the Danish Meteorological Institute (DMI) that peak summer Arctic sea ice volume upward growth trend has been extended yet another year – now 12 years.

The timing and size of three deadly earthquakes that struck Italy in 2016 may have been pre-determined, according to new research that could improve future earthquake forecasts.
A joint British-Italian team of geologists and seismologists have shown that the clustering of the three quakes might have been caused by the arrangement of a cross-cutting network of underground faults.
The findings show that although all three earthquakes occurred on the same major fault, several smaller faults prevented a single massive earthquake from occurring instead and also acted as pathways for naturally occurring fluids that triggered later earthquakes.

The world is on fire. Or so it appears in this image from NASA’s Worldview. The red points overlaid on the image designate those areas that by using thermal bands detect actively burning fires. Africa seems to have the most concentrated fires. This could be due to the fact that these are most likely agricultural fires. The location, widespread nature, and number of fires suggest that these fires were deliberately set to manage land. Farmers often use fire to return nutrients to the soil and to clear the ground of unwanted plants. While fire helps enhance crops and grasses for pasture, the fires also produce smoke that degrades air quality.

Les nouvelles politiques énergétiques et le choix des énergies renouvelables sont-ils en train de nous mener droit dans le mur ?
Hervé Machenaud a mené toute sa carrière professionnelle dans le secteur de l’énergie, où il a notamment contribué à la création de centrales nucléaires en France et à l’étranger et à la conception de l’EPR, le réacteur franco-allemand.
C’est en spécialiste des questions industrielles liées à l’énergie qu’il tire la sonnette d’alarme, mettant en cause des orientations politiques périlleuses, susceptibles selon lui de causer des dommages colossaux à nos sociétés dans leur ensemble.
UN CONSTAT IMPLACABLE
Au cours de la dernière décennie, ce sont des montants gigantesques de dépréciations qui ont été essuyés par les grands électriciens européens. Plus de 100 milliards d’euros rien qu’en quatre ans depuis 2014. Constat qui se paye par un désengagement préoccupant des grandes compagnies dans la production d’électricité. Au total, ce sont en effet 60 GW de moyens conventionnels d’électricité qui auront été arrêtés en Europe à la fin de la décennie, précise-t-il, soit l’équivalent du parc nucléaire français.

Napoleon’s defeat at Waterloo caused in part by Indonesian volcanic eruption
Electrically charged volcanic ash short-circuited Earth’s atmosphere in 1815, causing global poor weather and Napoleon’s defeat, says new research.
Historians know that rainy and muddy conditions helped the Allied army defeat the French Emperor Napoleon Bonaparte at the Battle of Waterloo. The June 1815 event changed the course of European history.
Two months prior, a volcano named Mount Tambora erupted on the Indonesian island of Sumbawa, killing 100,000 people and plunging the Earth into a ‘year without a summer’ in 1816.
Now, Dr Matthew Genge from Imperial College London has discovered that electrified volcanic ash from eruptions can ‘short-circuit’ the electrical current of the ionosphere – the upper level of the atmosphere that is responsible for cloud formation.
The findings, published today in Geology, could confirm the suggested link between the eruption and Napoleon’s defeat.

In a blockbuster study released Wednesday in Nature, a team of 38 scientists finds that the planet is home to 3.04 trillion trees, blowing away the previously estimate of 400 billion. That means, the researchers say, that there are 422 trees for every person on Earth.
However, in no way do the researchers consider this good news. The study also finds that there are 46 percent fewer trees on Earth than there were before humans started the lengthy, but recently accelerating, process of deforestation.
“We can now say that there’s less trees than at any point in human civilization,” says Thomas Crowther, a postdoctoral researcher at the Yale School of Forestry and Environmental Studies who is the lead author on the research. “Since the spread of human influence, we’ve reduced the number almost by half, which is an astronomical thing.”

As we all know, Greenland is warming up rapidly, causing the ice sheet to melt faster and faster.
Well, according to the BBC and New York Times, at least.
Only one slight problem – the temperature record shows quite a different story.
There is certainly no evidence of rising temperature trends, and every likelihood that temperatures will plummet again when the AMO turns cold again.

Total energy investment has fallen again…
2017 was the third consecutive year of decline in global energy investment with energy efficiency the lone sector of growth. Despite a 6% decline in spending, the electricity sector again attracted the largest share of energy sector investments, exceeding the oil and gas industry for the second year in row, as the energy sector moves toward greater electrification.

There seems to be a general acceptance about overall sea level trends during the Holocene.
There was naturally a very rapid rise in sea levels at the end of the ice age, until 6000 years ago, since when the rise has been much more gradual. Some research puts the rate of rise in the last 2000 years at 0.07mm/yr, and this reflects the fact that ice caps left over from the ice age are still melting, rather than that the world is warmer than before.
However, the impression is often given that, until the 20thC, this rate of rise has been pretty steady. This is despite the fact some of the authors of the above studies have warned of the existence of significant short-term fluctuations in sea level such that the sea level curve might oscillate up and down about this ~1 kyr mean state. [The above graph is based around 1000 year averages].
HH Lamb looked carefully at many expert studies in his day, and wrote about the very significant fluctuations they found. The following excerpts come from “Climate, History and the Modern World”:
1) The most rapid phases [of sea level rise] were between 8000 and 5000 BC, and that the rise of general water level was effectively over by about 2000 BC, when it may have stood a metre or two higher than today.

Il ne se passe pas un jour sans que surgisse sur les réseaux sociaux ou dans les médias une discussion sur le prix de l’électricité. Pour les uns, le prix de l’électricité produite par les énergies renouvelables est bas et pour les autres au contraire il est élevé. Qui a raison ?
Il faut examiner l’ensemble de la filière de la génération d’électricité pour pouvoir juger et non pas comme on le fait trop souvent se cantonner à un seul aspect. Nous allons donc procéder étape par étape, de manière à présenter de manière objective ce qu’il en est. Nous allons d’abord constater que la génération d’électricité à partir d’énergies renouvelables est déjà une forte réalité et qu’elle est en croissance. Nous allons ensuite observer qu’il est crucial d’équilibrer constamment la génération d’électricité et sa consommation et que cela ne peut se faire que par l’intermédiaire d’un réseau. Nous passerons ensuite au caractère intermittent de certaines énergies renouvelables et verrons quelles en sont les conséquences pour enfin pouvoir aborder la réalité des prix aux consommateurs. Dans la dernière partie nous allons parler du prix de l’électricité que nous payons en tant que consommateur et qui n’est pas bien entendu le coût de production.
Le but de cet article est qu’à travers cette démarche pédagogique le lecteur puisse se faire sa propre opinion sur la question du prix de l’électricité d’origine renouvelable.

Depuis des décennies l’hydrogène revient régulièrement à l’ordre du jour comme moyen de stocker l’énergie pour ensuite la convertir en électricité. Cette filière est particulièrement prisée dans le cadre d’une politique bas carbone vu qu’elle n’émet pas de gaz à effet de serre (GES ) la combustion de l’hydrogène ne produisant que de l’eau. Bien entendu la production de ce gaz doit elle-même « être propre ».
