The Department for Transport publishes a long-awaited aviation strategy today that pledges to deliver “greater capacity at UK airports”.
It raises the prospect of airports other than Heathrow growing and accepting more flights if tough environmental and noise restrictions are met.
The strategy also outlines plans for the biggest overhaul of Britain’s airspace in more than 50 years to create new flight paths into the biggest airports. GPS-style technology will allow aircraft to fly along more accurate paths below 30,000ft instead of being led by ground beacons, which space planes out over a wide arc several miles across.
It will mean a considerable increase to the 600 or so dedicated flight paths that are in operation today

Jochem Marotzke, director of Germany’s Max Planck Institute for Meteorology (MPIM), wondered whether CO2 savings could really have a direct influence on the temperature in the near future. In a new paper (Marotzke 2018), the Hamburg-based climate researcher simulates the temperature profile of the 2030s predicted by climate models and uses once again a conventional emission profile (Scenario RCP 4.5), and once a politically reduced emission scenario.
Conclusion: Most likely, there would probably be no difference as natural climate variability prevails over these time scales. The paper was published in WIRE’s Climate Change and can be downloaded free of charge as a pdf:

Scientists have described a fossil plant species that suggests flowers bloomed in the Early Jurassic, more than 174 million years ago, according to new research in the open-access journal eLife.
Before now, angiosperms (flowering plants) were thought to have a history of no more than 130 million years. The discovery of the novel flower species, which the study authors named Nanjinganthus dendrostyla, throws widely accepted theories of plant evolution into question, by suggesting that they existed around 50 million years earlier. Nanjinganthus also has a variety of ‘unexpected’ characteristics according to almost all of these theories.

Over the last 40 years global-mean surface air temperature – ‘global temperature’ for short – has gained an extraordinary role in the science, politics and public discourse of climate change. What was once a number crudely calculated through averaging together a few dozen reasonably well-spaced meteorological time series, has become reified as an objective entitythat simultaneously measures Earth System behaviour, reveals the future, regulates geopolitical negotiations and disciplines the human imagination. Apart perhaps from GDP rarely can so constructed an abstract entity have gained such power over the human world.

Negotiators in Poland have finally secured agreement on a range of measures that will make the Paris climate pact operational in 2020.
Last-minute rows over carbon markets threatened to derail the two-week summit – and delayed it by a day.
Delegates believe the new rules will ensure that countries keep their promises to cut carbon.
The Katowice agreement aims to deliver the Paris goals of limiting global temperature rises to well below 2C.
“Putting together the Paris agreement work programme is a big responsibility,” said the chairman of the talks, known as COP24, Michal Kurtyka.
“It has been a long road. We did our best to leave no-one behind.”

You may recall the BBC’s news story a couple of months ago, claiming that African penguin populations were declining because of climate change.
The report from South Africa, which then followed, made no mention of climate change at all but instead laid the blame fairly and squarely on overfishing.
This is not an isolated instance of false claims being made about climate change by the BBC. They now seem to be making a habit of it. — Paul Homewood, Not A Lot Of People Know That, 15 December 2018

Wavelet analyses of modern global temperature anomalies provides an excellent visualization tool of temperature signal characteristics and patterns over the past 150 years. Scafetta recognized key temperature oscillations of about 9, 20 and 60-years using power spectra of global surface temperature anomalies. There has been much discussion about the 60-year quasi-oscillation both in WUWT and publications.
Detrending the temperature time series and removing the 60-year underlying trend enables insights into the interplay of interannual and decadal scales. Wavelet analyses reveals these periodic signals have distinguished patterns and characteristics that repeat over time suggesting natural external and internal influences. Interannual wavelet patterns that consist of 9-year and 3 to 5-year quasi-oscillations are repeated and dominate over 70% of the instrumental record. The 3 to 5-year discontinuous breakouts are coincident to El Niño and La Niña events of the El Niño-Southern Oscillation (ENSO). A period of quiescence from 1925 to 1960 is devoid of most wavelet signals suggesting different or transitional climate processes.

Almost immediately after it was introduced to the public, the lead author of Marcott et al. (2013) squelched the narrative that said the hockey-stick-shaped reconstruction he and his colleagues produced is a robust representation of modern global-scale temperature changes.
In an interview with Marcott published by RealClimate.org, it was acknowledged that the “uptick” does not represent a global-scale reconstruction, as it is based on only a few proxy records and lacks statistical significance.
Despite this admitted lack of supporting evidence for the 20th century’s “uptick”, the Marcott et al. (2013) “hockey stick”-shaped graph has nonetheless been unskeptically cited by other authors nearly 700 times.

In this post, we’re going to present graphs that show the annual lowest TMIN and highest TMAX Near-Land Surface Air Temperatures (not in anomaly form) for ten (10) Countries in an effort to add some perspective to global warming. The list of countries, which follows, includes the countries with the highest populations.
And, as always with my posts, as part of the text, there are hyperlinks to the data that were used to prepare the graphs. Just click on the links if you’re looking for the data.
First of all, TMIN is described by Berkeley Earth as the “Mean of Daily Low Temperatures”, while TMAX is described as the “Mean of Daily High Temperatures”. Berkeley Earth provides monthly TMIN and TMAX data until partway through 2013. The start month for these individual-country datasets at Berkeley Earth depends on data availability from the individual country. Sometimes they start in the early 1800s, maybe even the mid-to-late 1700s for countries to be included in future posts (like the United Kingdom), and other times they start in the mid-to-late 1800s, so I’ve chosen 1900 as the start year for this post. The year 1900 is the end year of the IPCC’s new definition of “pre-industrial” times, so starting the graphs in 1900 is also appropriate in that respect.

Three minutes is not a lot of time, so let me be brief. I’ll start with something that might shock you. There is no evidence that CO2 has a large effect on climate. The two arguments used by the IPCC to so called “prove” that humans are the main cause of global warming, and which implies that climate sensitivity is high, are that: a) 20th century warming is unprecedented, and b) there is nothing else to explain the warming.
These arguments are faulty. Why you ask?
We know from the climate-gate e-mails that the hockey stick was an example of shady science. The medieval warm period and little ice ages were in fact global and real. And, although the IPCC will not admit so, we know that the sun has a large effect on climate, and on the 20th century warming in particular.
In the first slide we see one of the most important graphs that the IPCC is simply ignoring. Published already in 2008, you can see a very clear correlation between sea level change rate from tide gauges, and solar activity. This proves beyond any doubt that the sun has a large effect on climate. But it is ignored.

La COP est une conférence internationale qui depuis 24 ans tient chaque année la réunion de la dernière chance pour sauver la planète. Vous croyez peut-être que la planète avait été sauvée lors de la COP21 à Paris. Erreur. Tout reste à faire. C’est ce qui justifie la COP24, qui se tient cette année en Pologne. Le secrétariat de la COP24 publie en ligne la liste de ses participants, sur près de 1100 pages.
Plus de 21 000 participants. Sans compter les 1500 journalistes accrédités, qui sont rémunérés par leurs médias, pas par les contribuables. Ces 21 000 participants sont pour 14000 des délégués des gouvernements, et pour 6000 des représentants d’ONGs prétendument intéressées et compétentes. (Le solde est composé de membres d’organisations du système des Nations-Unies).
Le coût de la fête est élevé. Les seuls frais de déplacement et de séjour pour cette COP de 15 jours s’élèvent sans doute (sur la base de 10000 € par participant) à plus de 200 millions d’euros. On pourrait y ajouter le coût du temps passé par les participants. S’ils y passent en moyenne une semaine, cela fait 21000 semaines, soit environ 500 personnes-années. A 50000 euros/an, 25 millions d’euros, qui s’ajoutent aux frais de déplacement. C’est de quoi doubler le niveau de vie annuel de 2 ou 3 millions d’enfants au Malawi.

Dans un article récent de juin 2018, le biologiste Yinon Bar-On et ses collaborateurs ont estimé la biomasse totale de la biosphère actuelle (Bar-On et al. 2018). Pour cela, ils ont simplement estimé les nombres de bactéries, protozoaires, plantes et animaux dans tous les écosystèmes de la planète. En connaissant le poids moyen de chaque organisme, les auteurs ont ensuite réalisé des sommes. Ils arrivent au chiffre final de 550 gigatonnes (Gt) de carbone. Ce chiffre est-il élevé ? Avec quoi peut-on le comparer? Est-il précis ? Quels sont les organismes les plus importants dans la biosphère ? Quelles sont les conséquences pour le cycle du carbone, et donc pour la concentration de CO2 atmosphérique ? Voici toute une série de questions que l’on doit se poser. Nous allons voir que les résultats de Yinon Bar-On sont assez étonnants et qu’ils induisent des conséquences majeures pour le cycle du carbone dans la biosphère.

This post comes a couple of weeks after the post EXAMPLES OF HOW AND WHY THE USE OF A “CLIMATE MODEL MEAN” AND THE USE OF ANOMALIES CAN BE MISLEADING(The WattsUpWithThat cross post is here.)
I was preparing a post using Berkeley Earth Near-Surface Land Air Temperature data that included the highest-annual TMAX temperatures (not anomalies) for China…you know, the country with the highest population here on our wonder-filled planet Earth. The graph was for the period of 1900 to 2012 (FYI, 2012 is the last full year of the local TMAX and TMIN data from Berkeley Earth). Berkeley Earth’s China data can be found here, with the China TMAX data here. For a more-detailed explanation, referring to Figure 1, I was extracting the highest peak values for every year of the TMAX Data for China, but I hadn’t yet plotted the graph in Figure 1, so I had no idea what I was about to see.
Figure 1 The results are presented in Figure 2, and they were a little surprising, to say the least.

I keep reading about all kinds of crazy schemes to reduce US CO2 emissions. Now, I don’t think that CO2 is the secret knob that controls the climate. I think that the earth has a host of emergent thermoregulatory mechanisms that act to keep the temperature within narrow limits (e.g. 0.6°C temperature change over the entire 20th Century). I don’t believe the claims that the modern changes in CO2 will affect the temperature.
But solely for the purposes of this post, let’s assume that the alarmists are correct. And for purposes of discussion only, let’s assume that the Earth’s temperature is free to go up and down any amount. Let’s assume that CO2 is, in fact, the secret control knob that controls the temperature of the earth. And let’s further assume that the pundits are right that the “climate sensitivity” is three degrees of warming for every doubling of CO2.
And finally, let’s assume that in 2018 the US magically stopped emitting any CO2 at all.
With all of those assumptions as prologue, here’s the question of interest.
Other things being equal, if the US stopped emitting CO2 entirely in 2018, and stayed at zero CO2 emissions indefinitely, how much cooler would that make the planet in the year 2050?
Five degrees cooler? Two degrees? One degree?

She is confirming much of what I have said in recent years. The only thing I would take issue with his her description of there being a U-Turn. In my view, China never had the slightest intention of being serious about cutting emissions.

Un article de NoTricksZone
La conférence sur le climat de Katowice bat son plein et diverses initiatives visant à réduire les émissions de dioxyde de carbone sont à l’ordre du jour : manger moins de viande, se chauffer moins, prendre moins l’avion. Dans ce dernier cas, bien sûr, la conférence confine elle-même à l’absurde.
Il aurait été facile de transformer la conférence en une réunion sur Internet avec retransmission en direct et commentaires en ligne. Mais il aurait manqué quelque chose à ce long et merveilleux voyage d’affaires avec ses réceptions, ses indemnités journalières et ses réunions d’avant Noël entre sauveteurs du climat. Cette fois-ci, plus de 22 000 participants se sont rendus en Pologne, la plupart confortablement en avion. Les délégations les plus nombreuses à la Conférence sur le climat venaient d’Afrique.
La Guinée envoie 406 délégués cette année, la République démocratique du Congo y est présente avec 237 participants et la Côte d’Ivoire envoie 191 ressortissants en Pologne. La liste des participants est disponible sur la page d’accueil de la conférence en format pdf et compte 1084 pages.

The media, alarmist scientists and many leading policymakers often tell the public “the Arctic is rapidly melting”. And if a poll were done today, a vast majority of the people in Japan and elsewhere would say this is true. Unfortunately they have become the victims of “fake news”.
Luckily we have some hard data from the Arctic. And if one looks at them, it is true that sea ice has seen a declining trend – if we go back 40 years.
Yet, if we look at the past 12 years, we see that the trend for minimum has stopped, and one could argue even reversed:

An observational estimate of transient (multidecadal) warming relative to cumulative CO2 emissions is little over half that per IPCC AR5 projections.
AR5 claims that CO2-caused warming would be undiminished for 1000 years after emissions cease, but observations indicate that it would halve.

“The results of this review point to the extreme value of CO2 to all life forms, but no role of CO2 in any significant change of the Earth’s climate. … Many believe and/or support the notion that the Earth’s atmosphere is a ‘greenhouse’ with CO2 as the primary “greenhouse” gas warming Earth. That this concept seems acceptable is understandable—the modern heating of the Earth’s atmosphere began at the end of the Little Ice Age in 1850. The industrial revolution took hold about the same time. It would be natural to believe that these two events could be the reason for the rise in temperature. There is now a much clearer picture of an alternative reason for why the Earth’s surface temperature has risen since 1850.”
“There is no correlation of CO2 with temperature in any historical data set that was reviewed”.

Last year’s oceanic heat wave wasn’t as destructive as one the year before, scientists said.
The Great Barrier Reef fared better during an oceanic heat wave last year than during sizzling weather a year earlier that caused hundreds of miles of corals to bleach, according to a study published Monday that suggests the massive structure may be growing more tolerant to climate change.
The report in the journal Nature Climate Change analyzed how corals along the Great Barrier fared in back-to-back mass bleaching events. The reef ― a UNESCO World Heritage Site and the largest living structure on the planet ― was cooked by overheated seawater in 2016 and again in 2017, with images of sickly white coral horrifying people around the globe.

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.
