Attempts to incorporate a key scientific study into global climate talks in Poland have failed.
The IPCC report on the impacts of a temperature rise of 1.5C, had a significant impact when it was launched last October.
Scientists and many delegates in Poland were shocked as the US, Saudi Arabia, Russia and Kuwait objected to this meeting “welcoming” the report.
It was the 2015 climate conference that had commissioned the landmark study.

Le système d’échange de quotas d’émission de l’UE,connu sous l’acronyme SEQE-EU ou en anglais EU ETS, est instrument utilisé pour réduire les émissions de Gaz à Effet de Serre (GES) ou de CO2 pour faire court. Il repose sur un principe de plafonnement et d’échange des droits d’émission. Il a été adopté par la Commission Environnement du Parlement européen, le 13 octobre 2003.

The polar regions of the Earth have long been depicted as canary-in-the-coal-mine sentinels of climate change, given that climate models project that CO2-induced global warming will manifest itself here, first and foremost, compared to other planetary latitudes. Consequently, researchers are frequently examining the Arctic and Antarctic for evidence of recent climate change.
Clearly, as demonstrated here and in other studies (see, for example, The Antarctic Peninsula: No Longer the Canary in the Coal Mine for Climate Alarmists and the references therein) there is a canary in the Antarctic alright, but it is alive and well. And these counter-observations do not bode well for climate models and their projections of CO2-induced global warming.

Judith Curry, one of climate science’s most vocal critics, is leaving academe because of what she calls the poisonous nature of the scientific discussion around human-caused global warming.

The mainstream press coverage of the beginning of the Katowice climate summit is sad but fascinating.
There is a uniformly dogmatic sense of urgency based on fear, with very little news and a great deal of preaching.
Fear is the dominant theme.
I truly pity the people who hold these false beliefs, as they must be afraid of the future. But I am not sympathetic with the alarmism, because it makes people dangerous.
The preachers are calling on the faithful to change the world we live in, and not in a good way. Fear makes people angry and angry people are dangerous.
Here are just three examples of alarmist news coverage of the Katowice climate summit, a few among many.

The U.N.’s climate summit will emit as much carbon dioxide as more than 8,200 American homes.
It’s also equivalent to more than 11,700 cars driving for one year or 728 tankers trucks worth of gasoline.
When air travel is factored in, the summit’s emissions are likely higher, according to one expert.

More than two miles below the ocean’s surface, microbes, worms, fishes, and other creatures great and small thrive. They rely on the transport of dead and decaying matter from the surface (marine snow) for food at these dark depths.
Up near the sea surface, carbon dioxide from the atmosphere is incorporated in the bodies of microscopic algae and the animals that eat them. When they die, these organisms sink to the depths, carrying carbon with them.
This supply of carbon to the deep sea isn’t steady. At times, months’ to years’ worth of marine snow falls to the abyss during very short “pulse” events.
In a new study published in the Proceedings of the National Academy of Sciences (PNAS), MBARI scientists and their collaborators show that there has been an increase in pulse events off the coast of California. They also show that, although such episodes are very important to the carbon cycle, they are not well represented in global climate models.

Most of us are familiar with the World Meteorological Organization (WMO)-recommended 30-year period for “normals”, which are also used as base years against which anomalies are calculated. Most, but not all, climate-related data are referenced to 30-year periods. Presently the “climatological standard normals” period is 1981-2010. These “climatological standard normals” are updated every ten years after we pass another year ending in a zero. That is, the next period for “climatological standard normals” will be 1991-2020, so the shift to new “climatological standard normals” will take place in a few years.
But were you aware that the WMO also has another recommended 30-year period for “normals”, against which anomalies are calculated? It’s used for the “reference standard normals” or “reference normals”. The WMO-recommended period for “reference normals” is 1961-1990. And as many of you know, of the primary suppliers of global mean surface temperature data, the base years of 1961-1990 are only used by the UKMO.

While there’s little cobalt mining in China itself (1 percent of the world’s total output in 2017), Chinese companies have snapped up cobalt mines abroad in recent years, particularly in the Democratic Republic of Congo, the largest source of the metal.

Summary: Volume II of the Fourth National Climate Assessment (NCA) has dominated the news in the weeks since its release. One of the major findings that journalists headlined was the effect of climate change on the US economy. Ten percent is vivid number to grab the attention of Americans still skeptical after thirty years of dire warnings about climate change. Unfortunately it is a dubious story, as explained in these tweets by Roger Pielke Jr.

Talk about cold turkey! The coldest Thanksgiving in 100 years, and quite possibly the coldest Thanksgiving ever, has hit the Northeast United States today.
The unprecedented cold snap comes courtesy of a large Canadian chill working its way across the country on its way to the Atlantic. According to the Weather Network, the deep freeze is the result of a large, low pressure system moving south from the Arctic across the Great Lakes. Combine that with a wicked wind chill, and many Americans are looking at the coldest Thanksgiving in a century.

La raison d’être de la taxe carbone qui pèse sur les carburants est qu’en augmentant le prix des carburants en France, cette taxe va diminuer la consommation de carburant, et les rejets de CO2 qui vont avec. Le raisonnement est solide. Mais la question est : de combien ? C’est l’enjeu. L’augmentation de cette taxe met le pays à feu et à sang. C’est la chandelle. Le jeu en vaut-il bien la chandelle ?
Pour y répondre il faut connaître la sensibilité de la consommation au prix, ce qu’on appelle l’élasticité-prix. C’est le rapport de l’effet, la variation de consommation (mesurée en %) sur la cause, la hausse de prix (également mesurée en %). Si une hausse des prix de 10% entraîne une diminution de consommation de 8%, l’élasticité est de -0,8.

Fossil fuels helped humanity improve our health, living standards and longevity in just 200 years.
Then, suddenly, a great miracle happened! Beginning around 1800, health, prosperity and life expectancy began to climb … slowly but inexorably at first, then more rapidly and dramatically. Today, the average American lives longer, healthier and better than even royalty did a mere century ago.
How did this happen? What was suddenly present that had been absent before, to cause this incredible transformation?
Humanity already possessed the basic scientific method (1250), printing press (1450), corporation (1600) and early steam engine (1770). So what inventions, discoveries and practices arrived after 1800, to propel us forward over this short time span?

New research disputes a long-held view that our earliest tool-bearing ancestors contributed to the demise of large mammals in Africa over the last several million years. Instead, the researchers argue that long-term environmental change drove the extinctions, mainly in the form of grassland expansion likely caused by falling atmospheric carbon dioxide (CO2) levels.
The study is published today in the journal Science.
“Despite decades of literature asserting that early hominins impacted ancient African faunas, there have been few attempts to actually test this scenario or to explore alternatives,” Faith says. “We think our study is a major step towards understanding the depth of anthropogenic impacts on large mammal communities, and provides a convincing counter-argument to these long-held views about our early ancestors.”
To test for ancient hominin impacts, the researchers compiled a seven-million-year record of herbivore extinctions in eastern Africa, focusing on the very largest species, the so-called ‘megaherbivores’ (species over 2,000 lbs.) Though only five megaherbivores exist in Africa today, there was a much greater diversity in the past. For example, three-million-year-old ‘Lucy’ (Australopithecus afarensis) shared her woodland landscape with three giraffes, two rhinos, a hippo, and four elephant-like species at Hadar, Ethiopia.

One of the most basic things about journalism, especially BBC journalism, is that anyone should be able to find out what the corporation reported on a particular day about a particular story. Imagine wanting to find out about what Parliament voted for or what was the content of a UN speech, or the conclusions of a report, and not having full confidence that what you are able to look up is what was actually broadcast or written.
The public does not have access to data held in TV and Radio News archives, but they do to the articles published by BBC News Online. Sadly if you want to know what article was published about a certain subject on a particular day you cannot be sure the BBC Online News website is telling you the truth for history might have been rewritten 1984 style if recent antics in its Environment section are anything to go by.
