This contradicts climate alarmist claims such as: Global Warming Is Messing with the Jet Stream. Whether 40 years of data is enough to establish what is ‘normal’, is another matter. The fastest jetstream on record of 231 mph has only just been set, we’re told.

Rapid Arctic warming has not led to a “wavier” jet stream around the mid-latitudes in recent decades, pioneering new research has shown.

Scientists from the University of Exeter have studied the extent to which Arctic amplification—the faster rate of warming in the Arctic compared to places farther south—has affected the fluctuation of the jet stream’s winding course over the North Hemisphere, reports Phys.org.

Recent studies have suggested the warming Arctic region has led to a “wavier” jet stream—which can lead to extreme weather conditions striking the US and Europe.

However, the new study by Dr. Russell Blackport and Professor James Screen, shows that Arctic warming does not drive a more meandering jet stream.

Instead, they believe any link is more likely to be a result of random fluctuations in the jet stream influencing Arctic temperatures, rather than the other way around.

Apart from becoming school playground novelty items, what else is there?
One process requires pyrolysis: ‘After first chopping up the blades, pyrolysis breaks up the composite fibres in ovens with an inert atmosphere, at about 450-700C.’
But: ‘The problem is significant amounts of energy are needed to activate the pyrolysis, which might limit its environmental usefulness.’
Indeed, if you’re obsessed with avoiding burning fuels.
Some newer turbine blades are now nearly 100m. long.

Welcome to the wind turbine graveyard, says BBC News. It stretches a hundred metres from a bend in the North Platte River in Casper, Wyoming.

Between last September and this March, it will become the final resting place for 1,000 fibreglass turbine blades.

These blades, which have reached the end of their 25-year working lives, come from three wind farms in the north-western US state.

Each is about 90m (300ft) long, and will be cut into three, then the pieces will be stacked and buried.

A change to about 0.01% of the atmosphere is now claimed to be speeding up the oceans by making winds stronger. Really? They used to claim global warming was weakening the Pacific trade winds:
“The researchers predict another 10 percent decrease by the end of the 21st century. The effect, attributed at least in part to human-induced climate change, could disrupt food chains and reduce the biological productivity of the Pacific Ocean, scientists said.” (2006 report)

A study published today in the journal Science Advances, suggests global ocean circulation has accelerated during the past two decades, reports Phys.org.

The research team found that oceanic kinetic energy shows a statistically significant increase since early 1990s, calculating a 36-percent acceleration of global mean ocean circulation.

The trend is particularly prominent in the global tropical oceans, reaching depths of thousands of meters.

The deep-reaching acceleration of the ocean circulation is mainly induced by a planetary intensification of surface winds, authors said.

In short, Scottish wind power often produces too much for the electricity system to handle, yet more is planned. Meanwhile the super-expensive Western Link is failing miserably to draw off the excess power. Matt Ridley is trying to blow the whistle on this fiasco in the House of Lords, with some success.

Last weekend the Italian cable manufacturing company, Prysmian, released a statement announcing to the markets that the Western Link High Voltage Direct Current (HVDC) interconnector between Hunterston and Deeside had failed again, on the 10th of January, says the Renewable Energy Foundation.

This grid link, which is a joint venture between Scottish Power Transmission (SPT) and National Grid (NG), employs cables manufactured by Prysmian.

This £1 billion project has a peak transit capacity of 2.25 GW and was designed solely to facilitate the export of Scottish wind power to the English and Welsh markets.

In doing so it was expected to reduce constraint payments to wind power, payments which amount to £630m since 2010, with a record £130 million in 2019 alone.

The project was expected to come online at the end of 2015 but in fact did not become fully operational until late 2018 and has been plagued with faults ever since.

H/T The GWPF
Same old story, but numbers keep getting bigger. This just reinforces the point that large-scale surplus electricity can’t be stored. But nobody pays non-renewable sources for switching off or reducing output when wind and/or solar are operating at or near their capacity.
– – –
Wind farms were paid up to £3 million per day to switch off their turbines and not produce electricity last week, The Telegraph can disclose.

Energy firms were handed more than £12 million in compensation following a fault with a major power line carrying electricity to England from turbines in Scotland.

The payouts, which will ultimately be added onto consumer bills, were between 25 per cent and 80 per cent more than the firms, which own giant wind farms in Scotland, would have received had they been producing electricity, according to an analysis of official figures.

The causes of the foehn effect in the lee of mountains [image credit: Depunity @ Wikipedia]


Foehn (Föhn) winds are an interesting climatic phenomenon that cause rapid temperature changes. They’re well-known in Alpine regions but not so much in the UK.
– – –
The highest ever temperature recorded for the UK this late in the year was early on Sunday morning in the Scottish Highlands, reports LBC News.

A Met Office observation post in Cassley, in Sutherland, north Scotland, recorded a temperature of 16.8C at 3am on Sunday morning – this was well above the average nighttime temperature for that area in late December of zero degrees.

However given how early in the morning the high temperature was recorded, most people would have slept through it.

An eye-opener for wind turbine supporters, and everyone else who has to pay for them via taxes and power bills.

PA Pundits - International

By Duggan Flanakin ~

Wind turbines continue to be the most controversial so-called “renewable” energy source worldwide. Yet, you say, wind is surely renewable. Really? Sure, the wind blows intermittently, but what if wind power actually contributes to global warming?

While the wind itself may be “renewable,” the turbines surely are not. Arcadia Power reports that the widely used GE 1.5-megawatt (MW) turbine, is a 164-ton monster with 116-foot blades on a 212-foot tower that weighs another 71 tons. The Vestas V90, which has 148-foot blades on a 262-foot tower, has a total weight of about 267 tons. That is just ONE TURBINE!

How are these giants constructed? The U.S. Geological Survey, citing the National Renewable Energy Laboratory, states that turbines are predominantly made of steel (which comprises 71 to 79 percent of total turbine mass), fiberglass, resin, or plastic (11 to 16 percent), iron or cast iron (5 to…

Suddenly Saturn’s hexagon isn’t unique in the solar system any more.

Jupiter’s south pole has a new cyclone, reports Phys.org.

The discovery of the massive Jovian tempest occurred on Nov. 3, 2019, during the most recent data-gathering flyby of Jupiter by NASA’s Juno spacecraft.

It was the 22nd flyby during which the solar-powered spacecraft collected science data on the gas giant, soaring only 2,175 miles (3,500 kilometers) above its cloud tops.

The flyby also marked a victory for the mission team, whose innovative measures kept the solar-powered spacecraft clear of what could have been a mission-ending eclipse.

Omega blocking highs can remain in place for several days or even weeks [image credit: UK Met Office]


Another day, another attempt at a climate scare story. That’s a well-identified pattern too. But is this jet-stream pattern really ‘newly’ identified, or was it described by NASA nine years ago? Meteorology uses the term omega block. Which side of the block a region is on determines whether it’s warmer or colder than normal for the duration.

Scientists have identified systematic meanders in the globe-circling northern jet stream that have caused simultaneous crop-damaging heat waves in widely separated breadbasket regions-a previously unquantified threat to global food production that, they say, could worsen with global warming.

The research shows that certain kinds of waves in the atmospheric circulation can become amplified and then lock in place for extended periods, triggering the concurrent heat waves, reports Phys.org.

Affected parts of North America, Europe and Asia together produce a quarter of the world food supply. The study appears this week in the journal Nature Climate Change.

Could this point to an increasing difference between polar and equatorial average temperatures? Researchers cite ‘ocean-atmosphere oscillations’.

In a boon to wind farms, average daily wind speeds are picking up across much of the globe after about 30 years of gradual slowing, reports Phys.org.

Research led by a team at Princeton University shows that wind speeds in northern mid-latitude regions have increased by roughly 7% since 2010.

The findings mark a reversal of the pattern of declining winds in these regions since the 1980s—a phenomenon known as global terrestrial stilling.

A detailed look at why running countries on renewables is a dangerous delusion for practical reasons of economics and engineering. If short of time at least read the main headings. Add in the fact that people don’t want to live near wind turbines or give up land to accommodate them.

STOP THESE THINGS

Three decades, massive subsidies and yet intermittent wind power’s contribution to world energy needs remains little more than a rounding error.

Electricity that can’t be delivered as and when it’s needed has no commercial value; massive subsidies are the only ‘value’ that attracts investors to wind and solar. Cut the subsidies and wind and solar investment would evaporate, overnight.

As Gail Tverberg explains below, chaotically delivered wind and solar have never worked in the past. So, there’s no reason to expect that they’ll ever work in future. In a sane and rational world, we’d call it a ‘failed experiment’, clean up the mess and move on.

By what known physics could a few molecules of carbon dioxide upset the jet stream? A meteorologist is not impressed by such claims.

By Chris Martz | November 9, 2019
INTRODUCTION Just when wildfires weren’t enough, we now have people blaming cold weather on a warming climate, which seems quite contradictory.

In light of the Arctic outbreak in forecast this coming week, people like Phil Plait (who has since blocked me) took to Twitter (Figure 1) to claim that man-made climate change is causing frigid, Arctic air to be displaced south into the United States, Europe, and Asia.

His argument, which is supported by some climate scientists, suggests that man-made global warming causes the polar jet stream to destabilize causing it to become wavy rather than zonal, sending Arctic air southward into the mid-latitude regions.

He also stated that without global warming, the polar air would stay near the north pole.

Both of these claims are exactly backwards from reality and are not supported by weather dynamics, the global warming theory, or statistical observations in long-term temperature data.

‘Long-term’ here means really long-term. The 21k year precession period quoted looks like that of the perihelion.

In the past million years, the high-altitude winds of the southern westerly wind belt, which spans nearly half the globe, didn’t behave as uniformly over the Southern Pacific as previously assumed.

Instead, they varied cyclically over periods of ca. 21,000 years, reports ScienceDaily.

A new study has now confirmed close ties between the climate of the mid and high latitudes and that of the tropics in the South Pacific, which has consequences for the carbon budget of the Pacific Southern Ocean and the stability of the West Antarctic Ice Sheet.

What really happens – if anything – to land-based wind turbines at the end of their brief working lives?

STOP THESE THINGS

Wind turbines don’t run on wind, they run on subsidies: cut the subsidies and once these things inevitably grind to a halt, they’ll never be replaced.

With an economic lifespan of something like 10-12 years (rather than the overblown 25 put forward by turbine makers and wind power outfits), over the next decade countries like Germany will be left with hundreds of thousands of 2-300 tonne ‘problems’ littering the landscape. With hundreds of turbines totally kaput, Germans have already been smacked with the harsh and toxic reality of their government’s so-called ‘green’ obsession.

And they aren’t alone.

Iowa’s wind industry has been going for barely a decade and already wind power outfits are sending thousands of tonnes of toxic waste to landfill.

In addition to 10-15 tonne toxic plastic and fibreglass blades, there’s a smorgasbord of toxic plastics, oils, lubricants, metals and fibreglass in the tower and nacelle; and…

The fact that this kind of thing gets touted at all says a lot about the state of electricity generation in today’s trace-gas-fearing climate obsessed world. They talk of a ‘carbon free future’, but ignore the reality that world demand for oil, coal and gas is rising year on year as prosperity spreads around the globe and populations continue to increase.

It sounds like magic but it is real – a plan to store cheap night-time wind energy in the form of liquid air, reports BBC News.

Here is how: you use the off-peak electricity to compress and cool air in a tank, so it becomes a freezing liquid.

When demand peaks, you warm the liquid back into a gas, and as that expands it drives a turbine to create more electricity.

The technology, created by a backyard inventor, is about to hit the big time.

Looking past the smoke and mirrors game, we find the true financial pain being inflicted on UK electricity customers in the name of climate ideology aka the Climate Change Act.

The total annual renewables subsidy impact on UK household cost of living is £9 billion — which comes to £340 per year per household, says The Global Warming Policy Forum (GWPF).

The low and much-publicised offshore wind bids for Feed-in Tariffs with Contracts for Difference (FiTs CfDs) continue to confuse many analysts, even those from whom one might expect clear-eyed caution.

A writer for CapX (“What is the point of Corbyn’s nationalised wind farms?”), to select an example almost at random, quite correctly takes issue with the Labour Party’s reckless plans for major public investment in further offshore wind, but does so on the mistaken ground that “offshore wind is a big success story […] delivering ever more clean energy, at ever lower prices, for a fraction of the price of Labour’s plan”.

However, and as a matter of fact, none of the low-bidding wind farms have actually been built, and the 8.5 GW of operational offshore wind capacity which is “delivering” is without exception very heavily subsidised.

According to Wind Power Offshore, UK Decommissioning of 37 offshore wind farms in various stages of development in UK waters could cost the taxpayer between £1.28 billion (€1.44 billion) and £3.64 billion (€4.12 billion), a new report has revealed.

Developers and owners are liable to cover the costs, which are believed to be less than 1% of levelised cost of energy (LCOE), according to a study carried out for the Department for Businesses, Energy and Industrial Strategy (BEIS).

But if they are unable to organise and fund decommissioning, BEIS, seabed landlord the Crown Estate and the Scottish government could pick up the bill.

Stating the obvious, but most of the heat is in the oceans if compared to the heat in the atmosphere. Wikipedia says ‘the top 2.5 m of the ocean holds as much heat as the entire atmosphere above it.’ If improved predictions are expected, evidence of that will be needed.

University of Maryland (UMD) scientists have carried out a novel statistical analysis to determine for the first time a global picture of how the ocean helps predict the low-level atmosphere and vice versa, reports Phys.org.

They observed ubiquitous influence of the ocean on the atmosphere in the extratropics, which has been difficult to demonstrate with dynamic models of atmospheric and oceanic circulation.

Everything was definitely not clean about this major renewable energy operator. One report said that ‘crime and corruption crept in at several levels’.

Italy’s “Wind King”, or the “Lord of the Wind” Vito Nicastri has been sentenced to nine years in prison for channeling profits from his wind power business to the Cosa Nostra, says OilPrice.com.

The Guardian reports that Nicastri was stripped of his companies and property back in 2013 during an investigation into his ties with the Sicilian mafia. The assets that prosecutors seized were worth about $1.7 billion (1.3 billion euro).

Since then, the prosecution has established that Nicastri had “close ties to Matteo Messina Denaro” and other “high-level” contacts in the Sicilian mafia.
