German wind farm
Germany has more than 28,000 wind turbines — but many are old and by 2023 more than a third must be decommissioned. Disposing of them is a huge environmental problem.
Expert Jan Tessmer (coordinator on wind energy research at the German Aerospace Center (DLR)) tells DW he’s optimistic.
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.
The fix is in. UK prime minister Theresa May is on her hind legs telling us black is white and expecting us to swallow the lie. Brexit minsters David Davis and Steve Baker have resigned. Foreign secretary Boris Johnson has followed suit. Several parliamentary private secretaries have also resigned in protest at TMay’s non-brexit plan.
Lawyers for Britain chair Martin Howe has written this assessment of the ‘Chequers deal’ summary released to the press. It lays out in strong terms just how deceptive TMay is when she claims in parliament that her Chequers deal represents the Brexit the country voted for. If it was, those ministers wouldn’t have felt the need to resign their positions.
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.
Baidu’s self-driving mini bus on show in Shanghai.
One of China’s biggest technology companies has declared it has begun mass production of a self-driving bus, reports BBC News.
Baidu made the announcement after building its 100th Apolong vehicle at its factory in the country’s south-eastern Fujian province.
It said the vehicles would initially be put to commercial use within Chinese cities but added it was also targeting foreign markets.

Press Release from FME Law
July 3, 2018
One thousand seven hundred and sixty-three days ago, on behalf of its client, the Free Market Environmental Law Clinic, PLLC (FME Law) asked the University of Arizona to hand over public records that would expose to the world the genesis of what some consider the most influential scientific publication of that decade – the Mann-Bradley-Hughes temperature reconstruction that looks like a hockey stick.
The University refused.

Sweden will have to import more electricity during winter as the country, a net power exporter to the rest of Europe, shifts from nuclear to wind, its grid operator said.
The following calculations and graphics are based on information on worldwide CO2 emission levels published by BP in June 2018 for the period from 1965 up until the end of 2017.

The data can be summarised as follows:
Some initial points arising from the BP data:
Even as long ago as October 2010 Professor Richard Muller made the dilemma for all those who hope to control global warming by reducing CO2 emissions, particularly by means of CO2 reductions from Western Nations, clear: in essence he said:
“the Developing World is not joining-in with CO2 emission reductions nor does it have any intention of doing so. The failure of worldwide action negates the unilateral action of any individual Western Nation”.

Two decades ago, an engineer tried a new way to get gas out of the ground. Energy markets and global politics would never be the same, writes Russell Gold @ The Wall Street Journal.
DISH, Texas – Twenty years ago this month, a well was drilled here that changed the world.
Nothing at the time suggested the unassuming well in this rural town north of Fort Worth would hobble OPEC, the powerful oil cartel that had governed prices of the world’s most important commodity for more than a generation. Or that it would help turn the U.S. into a global energy exporter, or shuffle the geopolitical deck.
But it did all of that – and more.

An interesting contribution to the ice age debate here. Problems with Milankovitch and CO2-related theories are discussed.
Gerald Marsh, retired Argonne National Laboratories Physicist, challenges the usual assumption that ice age cycles are initiated by Milankovich Cycles and driven by the Arrhenius effect of carbon dioxide. He says that the key variable here is “low altitude cloud cover” driven by cosmic rays. A paper worth reading.

Talkshop readers may remember a damning report by UBS about the billions of public money lost in the ETS carbon trading system. It calculated that if the money had been invested in modernising the European power generation fleet, CO2 could have been cut by 40% (and generate a huge number of high quality jobs). EU emissions rose 1.8% last year.
Despite all the recent turmoil over the UK steel industry and meetings in Brussels today, the reality is that the European Union has actually been subsidising the Chinese steel industry for years, in payments hidden amongst its efforts to combat Climate Change.
Using complex methods of carbon credits and carbon offsets, the EU devised rules on climate change ended up paying Chinese steel manufacturers billions to upgrade their steel mills and other energy intensive industry.
According to the analysis company, European Insights, almost €1.5 billion was paid to over 90 steel plants in China with the purpose of modernising them to consume less energy, and making the plants more efficient. Taken with the downturn in Chinese trade and the need for them to reduce world market prices to sell their product, the output of these mills has flooded onto the European market making steel products artificially cheap and endangering thousands of jobs in the UK. One plant alone, Anshan Iron and Steel, received a payment of €150 million to help pay for the installation of up to date equipment and replace the old inefficient Communist era machinery.
Bank station on the Central Line
The London Underground is hot. But nowhere is hotter than the Central line, which is routinely so hot that it exceeds the EU limit at which it is legal to transport cows, sheep and pigs, says Wired UK.

CFACT’s kicked off a new billboard on busy I-10 in Louisiana which reads, “Russia funneled Green groups millions of dollars to oppose fracking & cripple American energy,” and asks, “How’s that for COLLUSION?”
The billboard campaign was spearheaded by CFACT’s Graham Beduze and Adam Houser.
Russia wants to reduce and eliminate competition to its energy exports with the goal of keeping prices high and the world, particularly Europe, dependent on Russian energy.

Antarctica
So cold it would be painful to breathe says ScienceAlert.
Just how cold can it get on Earth? Colder than we thought, apparently. A new study of satellite data reports that valleys in Antarctica’s ice sheets can reach close to minus 100 degrees Celsius (or minus 148 degrees Fahrenheit).
Bad news for beer-loving football fans in the UK as the World Cup progresses. This is the same gas that climate-obsessed governments want to spend a fortune of our taxes – some from beer – on capturing and burying. You couldn’t make it up.
Food wholesaler Booker is rationing beer and cider because of a shortage of CO2 used in carbonated drinks, reports BBC News.
The Tesco-owned retailer, which is used by bars, restaurants and traders, is capping customers to 10 cases of beer, and five of cider or soft drinks.
It is more evidence that a scarcity of CO2 is hurting the food and drink sectors, and comes after Heineken and Coca-Cola faced disruption.
Dead in the water: Swansea tidal lagoon [image credit: BBC]
A decision by the UK government not to back the world’s first tidal power lagoon could have been made 18 months ago, according to the man who led an independent review into the plans.
Charles Hendry backed the £1.3bn Swansea Bay project in his government-commissioned review of January 2017.
Climate miserablists wail, but public demand and commercial reality have taken priority. The skies over west London are set to become even busier. Air travel is expanding worldwide and protesters can’t change that, but the location is still controversial for some.
