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fellows of the society, as well as other concerned geoscientists, that the Society’s position on climate change is outdated and one-sided.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.

Climate scientists acknowledge that CO2 follows rather than leads temperature, but they insist that feedback loops drive the transitions from glacial to interglacial conditions.

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.
