Good luck to the mission. A somewhat optimistic claim made here is that this will ‘improve our understanding of manmade climate change’ but, as the report states without noting any irony, the name of the mission is drawn from mythology.

A satellite designed to measure Earth’s global wind patterns is set to be hoisted into orbit Tuesday from the Arianespace launch site in French Guiana, reports Phys.org.

The European Space Agency’s (ESA) Aeolus mission—named for the guardian of wind in Greek mythology—promises to improve short-term weather forecasting and our understanding of manmade climate change.

A new study finds that coral bleaching on the Great Barrier Reef is nothing new.

From the Evening Express:

Large-scale coral bleaching has raised concern about the future of the ecosystems and the impact their loss could have on biodiversity.

Dr Sebastian Hennige, researcher

The teams found the frequency of bleaching has increased since the 1800s and, despite corals’ ability to recover, there are fears they could now be approaching a “critical threshold”.

Dr Nick Kamenos from Glasgow’s School of Geographical and Earth Sciences said: “It’s clear in the core data we examined that bleaching has been occurring on the Great Barrier Reef for at least 400 years, but the frequency of bleaching events has increased markedly since the early 1800s and those events have affected 10% more corals since the late 1700s.

“We can see that corals have been able to acclimate and recover from past…

Nir Shaviv is co-author along with Henrik Svensmark and others of a major new paper in Nature Communications titled Increased ionization supports growth of aerosols into cloud condensation nuclei. He has a write up at his Sciencebits blog. Here’s the introduction:

Our new results published today in nature communications provide the last piece of a long studied puzzle. We finally found the actual physical mechanism linking between atmospheric ionization and the formation of cloud condensation nuclei. Thus, we now understand the complete physical picture linking solar activity and our galactic environment (which govern the flux of cosmic rays ionizing the atmosphere) to climate here on Earth though changes in the cloud characteristics. In short, as small aerosols grow to become cloud condensation nuclei, they grow faster under higher background ionization rates. Consequently, they have a higher chance of surviving the growth without being eaten by larger aerosols. This effect was calculated theoretically and measured in a specially designed experiment conducted at the Danish Space Research Institute at the Danish Technical University, together with our colleagues Martin Andreas Bødker Enghoff and Jacob Svensmark.

Figure 4: The correlation between the linearly detrended sea level measured using satellite altimetry (blue dots) and a model fit which includes just two components: The sun and el Niño southern oscillation. The excellent fit implies that the two components are by far the dominant source of sea level change on short time scales

Background:

It has long been known that solar variations appear to have a large effect on climate. This was already suggested by William Herschel over 200 years ago. Over the past several decades, more empirical evidence have unequivocally demonstrated the existence of such a link, as exemplified in the examples in the box below.

H/T The Global Warming Policy Forum (GWPF)

Industrial economies can never be run on part-time low output power sources, no matter how much money is wasted on them at the expense of much more reliable and powerful alternatives. However, stating the obvious and expecting many of today’s political leaders to understand it are two different things, it seems.

Getting out of the Paris Agreement was just the first step on the road to a realist global energy policy, writes Rupert Darwall.

Thirteen years ago, a Republican president who had pulled the United States out of an onerous climate treaty faced isolation at the annual gathering of Western leaders.

In which we learn that Youtube either doesn’t understand, or is not concerned about, the difference between natural warming and alleged man-made warming of the Earth climate system since the Little Ice Age ended.

PA Pundits - International

By David Wojick, Ph.D. ~

The lefty BuzzFeed News has a long article saying that YouTube is beginning to label videos related to the climate with a statement that the Earth is warming. Since this fact is not a matter of debate the labels are pointless. Since the videos from both sides get labeled the same, labeling is meaningless. The clueless alarmists think this is some sort of improvement.

The label simply says this: “Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth’s climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming.” In short the Earth is warming.

I have logged over 700 YouTube videos that are skeptical of climate change alarmism and not one argues that the Earth is not warming. The debate is entirely about the…

Climate change: ‘Hothouse Earth’ risks even if CO2 emissions slashed

It may sound like the title of a low budget sci-fi movie, but for planetary scientists, “Hothouse Earth” is a deadly serious concept.

Researchers believe we could soon cross a threshold leading to boiling hot temperatures and towering seas in the centuries to come.

Even if countries succeed in meeting their CO2 targets, we could still lurch on to this “irreversible pathway”.

Their study shows it could happen if global temperatures rise by 2C.

An international team of climate researchers, writing in the journal, Proceedings of the National Academy of Sciences, says the warming expected in the next few decades could turn some of the Earth’s natural forces – that currently protect us – into our enemies.

Each year the Earth’s forests, oceans and land…

Poland’s miners understandably don’t want their jobs to be sacrificed on the questionable altar of the UN’s climate ideology.

A government-backed trade union conference in Katowice this week puts mining jobs on the agenda of climate change negotiations, says Climate Change News.

Poland’s trade unions are mounting a defence of coal workers against the impacts of climate policies in a government-backed conference this week.

The “social pre-cop” meeting is an effort to influence the agenda of Cop24, the UN climate summit to be held in the same city of Katowice this December.

CO2islife concludes: ‘If you have to “adjust” the data to make your model work, your model is wrong, it is that simple.’

CO2 is Life

In any real science great care is given to “controlling” for exogenous factors. The whole purpose of the scientific method is to relate the impact of an independent variable upon a dependent variable, removed from any other factors. Y = mX + b + e, is the formula of a linear regression, and e is the error of the model. In order to minimize the “e,” one must control for as many outside factors that may impact the dependent variable as possible. In climate science, efforts to control for exogenous factors is completely absent. In fact, by choosing the highly flawed and “adjusted” ground measurements they are effectively maximizing the impact of exogenous factors on their data set and minimizing the usefullness of their preferred data set to identify and isolate the impact of CO2 on atmospheric temperatures.

In climate science, the main model being promoted is Temperature is a…

Why is Heathrow so hot?

In the report ‘hottest day ever’ must mean ‘since the weather station was installed’, but we’re used to this kind of excitable exaggeration in BBC climate reporting. At least they are admitting the obvious here, that Heathrow has certain heat-related factors built-in.

It’s Europe’s busiest airport, says BBC News, and as well as attracting millions of passengers could Heathrow also be a magnet for the sizzling heat?

Heat Wave AGW Hysteria Not So Much. Why?

The media is still long on climate assertions and short, if not bereft, of any supporting science – other than yet more assertions from so-called experts of the climate alarm variety.

Science Matters

An editorial at Investor’s Business Daily poses the question: Why Hasn’t The California Heat Wave Sparked The Usual Global Warming Hysteria?  Excerpts in italics with my bolds.

It wasn’t long ago when the mainstream press took every opportunity, no matter how weak the connection, to blame bad things on global warming. So far, at least, we haven’t found one major story using the heat wave gripping the southwest to sound the alarm about global warming.

This lack of alarmism has not gone unnoticed.

Writing at the New Republic this week, Emily Atkin complained that despite record-breaking heat and a wildfire season that, she says, is already worse than usual, “there’s no climate connection to be found in much news coverage, even in historically climate-conscious outlets like NPR and The New York Times.”

When Atkin contacted NPR for an explanation, the network’s science editor said “You don’t just want…

The occasional hot summer in the UK is nothing new. There was one in 1976 and, as Booker points out, a particularly hot one as long ago as 1846. As usual the behaviour of the jet stream is a major factor.

Yes it’s scorching, but claims that the heatwave is down to climate change are just hot air: June was even hotter when Victoria was on the throne, writes CHRISTOPHER BOOKER for the Daily Mail.

There is at least one thing about this summer of 2018 on which we can all agree: the past months have unquestionably been swelteringly, abnormally hot.

They say all good things come to an end, and in this case the rug is being pulled away from support for various types of renewable project including small-scale solar systems, as PEI reports. Cue the usual wailing about the harmless trace gas carbon dioxide, as ever falsely described as ‘carbon emissions’. Coincidentally perhaps, the closure date coincides with the UK’s exit from the European Union.

Renewables and sustainability groups have reacted with fury to proposals by the UK government to scrap subsidies for green energy projects.

The feed-in tariffs scheme is the government’s subsidy scheme for small-scale low-carbon installations.

A consultation paper published yesterday sets out a proposal to close the export tariff alongside the generation tariff on 31 March 2019.

Question: If I had a container, full with air, and I suddenly decreased the volume of the container, forcing the air into a smaller volume, will it be considered as compression, will it result in an increase in temperature, and why?

Answer on Stack Exchange by Luboš Motl: Yes, it is compression and yes, it will heat up the gas.

If there’s no heat exchange between the gas and the container (or the environment), we call it an adiabatic process. For an adiabatic process involving an ideal gas (which is a very good approximation for most common gases), pVγ is constant where γ is an exponent such as 5/3. Because the temperature is equal to T=pV/nR and pV/pVγ=V1−γ is a decreasing function of V, the temperature will increase when the volume decreases.

Macroscopically, the heating is inevitable because one needs to perform work p|dV| to do the compression, the energy has to be preserved, and the only place where it can go is the interior of the gas given by a formula similar to (3/2)nRT.

Ructions as poor financial management and zero dollars from the US drain the UN’s so-called ‘green climate fund’. Even agreeing an agenda was a major struggle.

Rich and poor country representatives clash over policy priorities and replenishment at Green Climate Fund board meeting, reports Climate Change News.

Update on Wednesday 4 July: UN climate fund chief resigns for personal reasons while board meeting collapses

Disputes between rich and poor nations at the UN’s flagship climate fund are intensifying as the money runs low.

A meeting of the Green Climate Fund (GCF) board in Songdo started unevenly on Sunday, as co-chair Paul Oquist was detained by political turmoil in Nicaragua, leaving Sweden’s Lennart Båge to run the session single-handed.

With developing countries complaining their priorities were not properly represented, it took nearly two days to agree on the agenda for the meeting.

Fool Me Once Shame on You,

It was just 30 years ago this week that James Hansen, the former NASA scientist who testified before the Senate Energy and Natural Resources Committee during a prolonged heat wave, which” he described as a climate event of cosmic significance.” Just to be sure he arranged for the meeting room to be warmer than usual. He expressed to the senators “his high degree of confidence” in “cause-and-effect relationship between the greenhouse effect and observed warming.”

There was an accompanying paper in the Journal of Geophysical Research, and it ignited a world wide panic that continues today about the energy structure of the entire planet. So 30 years on we can pause and take a look at just how well his predictions have turned out, and check on how we are doing.
