Yes… I know entropy falls under the Second Law of Thermodynamics… But I doubt the author of the Clean Technica article does. [Author’s note: By “falls under the Second Law of Thermodynamics, I don’t mean decreases; I mean it falls under the “jurisdiction” of the Second Law of Thermodynamics.]

Michael Bloomberg est un milliardaire américain (pas un petit : l’une des vingt plus grosses fortunes mondiales), membre du parti démocrate, ancien maire de New York. C’est naturellement un farouche défenseur de l’environnement, ce qui lui a valu d’être nommé par le Secrétaire Général des Nations-Unies « envoyé spécial pour l’action climatique ». On ne peut pas le soupçonner de minorer le développement des énergies propres.
LES INVESTISSEMENTS DANS L’ÉNERGIE « PROPRE » SONT EN DÉCLIN
Le rapport1 que publie l’entreprise qu’il dirige (en fait une filiale consacrée aux énergies nouvelles) montre que les investissements dans « l’énergie propre », définie comme l’éolien et le photovoltaïque, ont diminué dans la plupart des pays du globe au cours des années 2010. Le point haut a été atteint en 2011. Depuis cette date, les investissements stagnent ou diminuent, à des taux divers selon les pays et les années.
La COP21, en 2015, devait sauver le monde grâce à des investissements massifs dans ces domaines. Elle n’a rien fait de tel. Au contraire, les années 2016, 2017 et 2018 sont marquées par une accélération de la baisse des investissements.

This article claim ships will “be able to sail right over the North Pole” by 2050 due to warming, but at the same time say ship tracks will make more clouds and cool the Arctic. Of course, anything is possible with the help of climate models.
More ships and more clouds mean cooling in the Arctic
With sea ice in the Arctic melting at an alarming rate, opportunities for trans-Arctic shipping are opening up, and by mid-century ships will be able to sail right over the North Pole – something not previously possible for humankind.

Dans les années 80, la découverte dans les archives glaciaires d’une corrélation entre température et taux de CO2 permit de soupçonner une influence anthropique sur le climat: les taux mesurés depuis 1958 étaient supérieurs aux taux des archives glaciaires.
L’IPPC (GIEC) fut créé en 1988 par 2 organismes: United Nations Environment Programme (UNEP) et World Meteorological Organization (WMO). Le GIEC attribue l’intégralité de la hausse du taux de CO2 depuis un siècle à l’influence humaine. Pour les dernières décennies, nous examinerons ici les mesures disponibles, les corrélations CO2 / température, enfin le modèle anthropique GIEC sera confronté à un modèle concurrent.…

Even before Hurricane Florence made landfall somewhere near the border of North and South Carolina, predicted damage from potentially catastrophic flooding from the storm was already being blamed on global warming.
Writing for NBC News, Kristina Dahl contended, “With each new storm, we are forced to question whether this is our new, climate change-fueled reality, and to ask ourselves what we can do to minimize the toll from supercharged storms.”
The theory is that tropical cyclones have slowed down in their speed by about 10 percent over the past 70 years due to a retreat of the jet stream farther north, depriving storms of steering currents and making them stall and keep raining in one location. This is what happened with Hurricane Harvey in Houston last year.
But like most claims regarding global warming, the real effect is small, probably temporary, and most likely due to natural weather patterns …

On the terminations of Ice Ages.
Terminations occur on solar up-lobes
There is no doubt that there is merit in the widely accepted Milankovitch theory that Ice Ages and their terminations are controlled by solar input to the NH in mid-summer. It is also clear that relying on the solar input to the NH alone, does not adequately account for the occurrence of terminations of Ice Ages. The variation of solar input to high latitudes is modulated by precession, which produces continual up-lobes and down-lobes in solar input with a ~ 22,000-year period. While every termination is accompanied by the 5,500-year rising portion of an up-lobe in the solar input to high latitudes, many strong up-lobes do not produce a termination….

The end of the Little Ice Age in the European Alps has long been a paradox to glaciology and climatology. Glaciers in the Alps began to retreat abruptly in the mid-19th century, but reconstructions of temperature and precipitation indicate that glaciers should have instead advanced into the 20th century. We observe that industrial black carbon in snow began to increase markedly in the mid-19th century and show with simulations that the associated increases in absorbed sunlight by black carbon in snow and snowmelt were of sufficient magnitude to cause this scale of glacier retreat. This hypothesis offers a physically based explanation for the glacier retreat that maintains consistency with the temperature and precipitation reconstructions.

The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research.
Scientists have for centuries believed that England, Wales and Scotland were created by the merger of Avalonia and Laurentia more than 400 million years ago.
However, geologists based at the University of Plymouth now believe that a third land mass — Armorica — was also involved in the process.
The findings are published in Nature Communications and follow an extensive study of mineral properties at exposed rock features across Devon and Cornwall …

Given the impending global warming crisis declared by scientists, it should be easy to unambiguously demonstrate the crisis from the instrumental record. Unfortunately, when looking at the high temperature record for the US, it does not show any warming.
Figure 1 illustrates the incremental changes in surface air temperatures based on year to year differences in station average Tmax. The data is from all active stations in the US Historical Climatology Network (USHCN) from 1895 to 2014.
The classic heat equation defines changes in heat content as being proportional to changes in temperature (ΔQ = ƒ{ΔT} ).
Thus, Figure 1 amounts to a depiction of incremental changes in heat content, without scaling in energy units. The overall net temperature change is 0, which means the net change in heat content is also zero (ΔQ = ƒ{ΔT} = ƒ{0} = 0).

Black carbon refers to tiny carbon particles that form during incomplete combustion of carbon-based fuels. Black carbon particles absorb sunlight, so they are considered to contribute to global warming. However, the contribution of black carbon to the heating of the Earth’s atmosphere is currently uncertain. Models that can accurately assess the warming effect of black carbon on our atmosphere are needed so that we can understand the contribution of these tiny carbon particles to climate change. The mixing state of black carbon particles and their particle size strongly influence their ability to absorb sunlight, but current models have large uncertainties associated with both particle size and mixing state.

WUWT readers may recall that climate activists wanted the current epoch we live in to be named the “Anthropocene”, because they believe humans are the dominate force on the planet. The official organization that decides such things, The International Commission on Stratigraphy, would have none of it, and nixed the naming recently. Now, here’s a summary of the the Meghalayan.

Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016, reports a new study in Nature.
Researchers using satellite data tracked the changes in various land covers to find that gains in forest area in the temperate, subtropical, and boreal climatic zones are offsetting declines in the tropics. In addition, forest area is expanding even as areas of bare ground and short vegetation are shrinking. Furthermore, forests in montane regions are expanding as climate warming enables trees to grow higher up on mountain.

The question is how does the Intergovernmental Panel on Climate Change (IPCC) determine that an increase in atmospheric CO2 causes an increase in global temperature? The answer is they assumed it was the case and confirmed it by increasing CO2 levels in their computer climate models and the temperature went up. Science must overlook the fact that they wrote the computer code that told the computer to increase temperature with a CO2 increase. Science must ask if that sequence is confirmed by empirical evidence? Some scientists did that and found the empirical evidence showed it was not true. Why isn’t this central to all debate about anthropogenic global warming?

Even though CO2 concentrations hovered well below 300 ppm throughout most of the Holocene, newly published paleoclimate reconstructions affirm that today’s surface temperatures are only slightly warmer (if at all) than the coldest periods of the last 10,000 years. This contradicts the perspective that temperatures rise in concert with CO2 concentrations.

Lets all bow to the IPCC — a modern God that shalt not be questioned. The Holy Sacred Climate Cow!
The IPCC is an unaudited and unaccountable foreign committee. Not only are no scientists paid to check its findings, now the publicly mandated BBC is making sure none of their journalists will check its findings either.
Carbonbrief has a copy of the BBC new internal guidance on how to report climate change.
In April, the UK regulator, Ofcom, found the BBC was guilty of not sufficiently challenging Lord Lawson, a skeptic. So in response the BBC now promises they will never sufficiently challenge the IPCC. That’s “false balance” for you.

From the University of Bristol and the “models before measurements” department comes this highly speculative claim that is entirely based entirely on climate models. There’s no actual measured data from any sort of paleo research. It’s science, but not as we know it.
A new study by scientists at the University of Bristol has shown that ancient global warming was associated with intense rainfall events that had a profound impact on the land and coastal seas.
The Palaeocene-Eocene Thermal Maximum (PETM), which occurred about 56 Million years ago, is of great interest to climate scientists because it represents a relatively rapid global warming event, with some similarities to the human-induced warming of today.
Although there have been many investigations of how much the Earth warmed at the PETM, there have been relatively few studies of how that changed the hydrological cycle.

This article in something called Inside Climate News seems to be typical of many I have seen this year: Because we have had much attention in the media on heat waves this year, there must be an upward trend in heat waves and that is a warning signal that man-made global warming is destroying the planet. Typical of these articles are a couple of features
Declaration of a trend without any actual trend data, but just a single data point of events this year
Unstated implication that there must be a trend because the author can’t remember another year when heat wave stories were so prevalent in the media
Unproven link to man-made global warming, because I guess both involve warmth.
