Probably not much of a shock. One researcher said: “The models are accurate in projecting at a global scale that cyclones in the future are highly likely to be more intense because of climate change. But they are less accurate in projecting how those cyclones will affect individual coral reefs — that is the result of more localised conditions such as the pounding of waves.” But ‘accurately projecting’ that something is ‘highly likely’ in the future sounds more like an assertion than actual science.

Climate models are unreliable when it comes to predicting the damage that tropical cyclones will do to sensitive coral reefs, according to a study published in the journal Earth’s Future.

With the expectation that tropical cyclones will increase in intensity with climate change, there has been interest among conservationists to use the models to identify the vulnerability of reef communities to storm damage, and to target conservation and protection efforts at those coral reefs that are less likely to be impacted by climate change, says Science Daily.

But a team of researchers from the University of Leeds in the UK, the Australian Institute for Marine Science and the Commonwealth Scientific and Industrial Research Organisation (CISRO) is urging caution when using the climate models, arguing they are not yet reliable enough to determine which reefs will be most at risk from cyclone damage.

A 2020 news report (H/T Belfast Telegraph) headlined Extreme weather being caused by jet stream ‘not because of Arctic warming’, with the sub-heading: ‘Any link is more likely to be a result of random fluctuations in the jet stream influencing Arctic temperatures, researchers say’ – cites a study that comprehensively contradicts the findings described in the article below. “The well-publicised idea that Arctic warming is leading to a wavier jet stream just does not hold up to scrutiny”, said Professor James Screen [University of Exeter]. “With the benefit of 10 more years of data and model experiments, we find no evidence of long-term changes in waviness despite on-going Arctic warming.” But the stated lack of evidence hasn’t deterred this new research. Are they flogging the proverbial dead horse?
– – –
A quartet of researchers, two with the Nordic Institute for Theoretical Physics and two with Pukyong National University, has created a group of simulations of changes to the jet stream under global warming, says Phys.org.

In their paper published in Proceedings of the National Academy of Sciences, the group describes using math theory to describe wind motion under given circumstances to create their simulations.

Over the past several years, the jet stream has become wavier than it used to be. Both peaks and valleys have become more extreme.

This has led to changes in weather patterns—some places have grown wetter and some drier, and there have also been more extended hot and cold spells around the globe.

This has been the case since the Climate Change Act was passed in 2008 with minimal political debate, even without ‘perverse loopholes’ in contracts. Renewable energy is in effect a licence to print money.

London, 1 September: Net Zero Watch has condemned the Government’s green energy policies as “a national disaster.”

This follows the announcement that a major offshore windfarm will not activate an agreement to sell power at a much lower cost to the grid.

The Times has reported that the Hornsea 2 windfarm, which had a contract to sell power at £73 per megawatt hour, will instead sell in the open market, where prices have averaged £200 per megawatt hour this year, and reached £508 last week.

At least they admit solar panels don’t like too much sun: ‘work much less well in high temperatures’. But high pressure systems often mean very low wind speeds.

The ongoing drought in the UK and Europe is putting electricity generation under pressure, say experts.

Electricity from hydropower – which uses water to generate power – has dropped by 20% overall, says BBC News.

And nuclear facilities, which are cooled using river water, have been restricted.

There are fears that the shortfalls are a taste of what will happen in the coming winter.

So much for ‘keeping it in the ground’, as climate obsessives like to intone to anyone who will listen to their anti-oil rants.

On Sunday, puzzled Swedish journalist and political commentator Peter Imanuelsen tweeted the news: “A wind power turbine just collapsed in Sweden”, says CNS News.

“People are being warned to keep their distance because…it is now leaking oil everywhere! “Wait, these “green” wind turbines use oil???”

As a recent paper noted: ‘a comprehensive understanding of the global dust cycle and its climatic and environmental impacts has significant scientific and practical implications. Our current knowledge about dust aerosols is still limited.’
– – –
A new instrument headed to the International Space Station (ISS) will help researchers learn how dust storms heat or cool the planet, says Phys.org.

NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission, which launched today, will greatly broaden scientists’ view of areas affected by mineral dust.

“Currently, the dust impacts of climate change are based on about 5,000 samples of soil for the entire Earth. EMIT will collect more than 1 billion usable measurements for the arid regions of the world,” said Planetary Science Institute Senior Scientist Roger Clark, a Co-Investigator on the EMIT mission.

It’s an obvious problem that politicians ‘would much rather not talk about’, as the article puts it, while noting it may be ‘good news, at least for birds’. Running away from reality isn’t going to work.
– – –
The Texas energy grid has been under severe stress due to a heatwave, and lower than average wind speed means wind energy has been unable to counter demand, says OilPrice.com.

Texas is suffering a major heat wave. Three-digit temperatures are straining the state’s grid and earlier this month prompted ERCOT, the Lone Star State’s grid operator, to ask Texans to conserve energy. It also severely affected wind power generation.

Bloomberg reported this week that wind turbines in Texas are operating at just 8 percent of their capacity because of low wind speeds. This is really unfortunate because demand for electricity is on a strong rise because of the weather.

Climate alarmists touting greater intensity and/or frequency of strong hurricanes, while advocating endless renewables, ought to take note of this.

PA Pundits - International

By David Wojick, Ph.D. ~

My regular readers know that I have been fussing about the threat of hurricanes destroying proposed Atlantic coast offshore wind arrays. The issue arises because the offshore wind industry is based in Europe, which does not get hurricanes. My focus has been Dominion’s massive project off Virginia, but the whole East Coast is hurricane alley.

Now I have found some research that actually quantifies the threat and it is very real. It looks like wind generators will have to be redesigned specifically to withstand hurricanes. In fact that work is underway. In the meantime we should not be building conventional offshore wind towers.

The 2017 press release is succinctly titled “Offshore wind turbines vulnerable to Category 5 hurricane gusts”. The PR says this: “The study, which was conducted in collaboration with the National Center for Atmospheric Research in Boulder, Colorado, and the U.S. Department of Energy’s

Unusually, this is the third year in a row under La Niña.

La Niña conditions and warm ocean temperatures have set the stage for another busy tropical storm year, says Eos.

If forecasts are correct, this season will mark the seventh consecutive above-normal hurricane season for the Atlantic.

NOAA forecasts out today predict a 65% chance of an above-average season, a 25% chance of a normal season, and a 10% chance of a below-normal season. The ranges account for uncertainty in the data and models of NOAA’s Climate Prediction Center.

Much ado about sea ice in recent times, but usually in terms of promoting climate alarm. On closer inspection East Antarctica (2/3rds of the continent) tells a somewhat different story.
– – –
Some ice shelves in the eastern Antarctic have grown in the last 20 years despite global warming, a study suggests.

Researchers say that sea ice, pushed against the ice shelves by a change in regional wind patterns, may have helped to protect the ice shelves from losses, reports Yahoo News.

Ice shelves are floating sections of ice attached to land-based ice sheets and they help guard against the uncontrolled release of inland ice into the ocean.

Even more expensive electricity, in pursuit of mythical net zero targets. The planned 25% contribution of nuclear power doesn’t give much confidence about where the other 75% should come from when it’s dark and not windy. Why the claimed ‘cheap renewables’ need not-cheap subsidies is not explained, and hydrogen isn’t cheap either.

The Energy Security Strategy announced by government just under a fortnight ago “provides a clear, long-term plan to accelerate [the UK’s] transition away from expensive fossil fuel prices set by global markets [it] cannot control.”

That’s according to Business Secretary Kwasi Kwarteng, who delivered a speech explaining his views on the new strategy and how he believes it can help shift the British energy market, reports Energy Live News.

“More wind, more solar, more nuclear – while also using North Sea gas to transition to cheaper and cleaner power,” was his succinct summary of the new strategy.

Lord Frost was unimpressed by the UK’s newly announced energy plan. Government bluster about hydrogen and biomass has minimal credibility. They believe the climate guff and all decisions flow from that. Expensive and risky.

A former Cabinet Minister has warned people could face the rationing of energy as a result of the implementation of the recent Energy Security Strategy, reports Energy Live News.

Lord Frost said: “I was not massively convinced that the energy security paper really changed anything much. I think it does not deal with the problem that it’s all very well to build a lot of wind power but it needs a backup by other power for when the wind does not blow and I did not see that problem really addressed in the security paper.”

Brussels has launched a legal challenge over the use of British parts in the UK’s offshore wind farms, reports the Telegraph.

The European Commission submitted its complaint to the World Trade Organisation (WTO), the first such move it has made since Brexit.

The UK Government asks offshore wind farm developers to say how many of the parts they are using are from Britain.

STOP THESE THINGS

In a world-first, neighbours tormented by wind turbine noise have won a landmark victory, forcing the operator to shut down all of its turbines at night-time.

Yesterday, Justice Melinda Richards of the Victorian Supreme Court slapped an injunction on a wind farm because the noise it generates has been driving neighbours nuts for seven years, and the operator has done absolutely nothing about their suffering.

Her Honour also ordered damages, including aggravated damages for the high-handed way in which the operator has treated its victims. Since March 2015, the community surrounding the Bald Hills wind farm have been tortured by low-frequency noise and infrasound generated by 52, 2 MW Senvion MM92s.

Neighbours started complaining to the operator about noise, straightaway. But, as is their wont, the operator simply rejected the mounting complaints and carried on regardless.

Locals, however, were not perturbed. Instead, they lawyered up. Engaging the tough and tenacious

Do Wind Farms Change The Weather?

More research needed it seems, but it hasn’t been ruled out.

PA Pundits - International

By David Wojick, Ph.D. ~

The effect of lots of wind turbines on weather and climate is a small but active research area. Wind power converts wind energy into electricity, thereby removing that energy from the air.

The research issue of how taking a lot of energy out might affect weather or climate seems to have emerged as early as 2004. Studies range from the global climate impact down to the local effects of a single large wind facility.

Here is a nontechnical article on a key global climate scale paper in 2011: “Wind and wave farms could affect Earth’s energy balance“in New Scientist magazine, March 30, 2011.

Forecaster highlights the jetstream over the UK [image credit: BBC]


Worth noting, even if the somewhat vague conclusion favoured here is that it’s likely to be an effect of global warming (etc.).
– – –
New research from the University of Southampton shows that the winter jet stream over the North Atlantic and Eurasia has increased its average speed by 8% to 132 miles per hour, says Phys.org.

The jet stream, which this week brought storms Dudley, Eunice and Franklin to the UK, has also has moved northwards by up to 330 kilometers.

The findings relate to the 141-year period from 1871–2011.

Spoiler: the Met Office wouldn’t ask its ‘more common’ question if it was confident it knew the answer. Instead it turns to its new buzz term: “sting jet”.
– – –
The UK Met Office has issued two red weather warnings in as many months for strong winds, says Phys.org.

These are the highest threat levels meteorologists can announce, and are the first wind-only red warnings to be issued since 2016’s Storm Gertrude.

So what’s behind the UK’s recent spate of dangerous wind storms? And are these events likely to become more common in future?

Storm Arwen in late November 2021 caused devastation across Scotland, northern England and parts of Wales. Winds of 100mph killed three people, ripped up trees, and left 9,000 people without power for over a week in freezing temperatures.

The destruction caused by Arwen is still apparent in some areas, and the clean-up from Storm Dudley—which battered eastern England on Wednesday February 16—is underway at the time of writing.

Now the UK faces Storm Eunice, and its gusts of up to 122 miles per hour. Eunice bears a striking similarity to the “Great Storm” of 1987, which unleashed hurricane-force winds and claimed 22 lives across Britain and France in October of that year. Both are predicted to contain a “sting jet”: a small, narrow airstream that can form inside a storm and produce intense winds over an area smaller than 100 km.

Sting jets, which were first discovered in 2003, and likely occurred during the Great Storm and Storm Arwen, can last anywhere between one and 12 hours. They are difficult to forecast and relatively rare, but make storms more dangerous.

Sting jets occur in a certain type of extratropical cyclone—a rotating wind system that forms outside of the tropics. These airstreams form around 5km above the Earth’s surface then descend on the southwest side of a cyclone, close to its center, accelerating as they do and bringing fast-moving air from high in the atmosphere with them.

When they form, they can produce much higher wind speeds on the ground than might otherwise be forecast by studying pressure gradients in the storm’s core alone.

Meteorologists are still working to understand sting jets, but they are likely to have a significant influence on the UK’s weather in a warming climate. [Talkshop comment: Isn’t everything, in Met Office model world?]
. . .
Our research team’s new high-resolution climate models predict bigger increases in winter rainfall than standard global climate models due to a large increase in rainfall from thunderstorms during winter.

We are less certain about how the pattern of extreme wind storms, like Eunice, will change, as the relevant processes are much more complicated.

The UK’s recent cluster of winter wind storms is related to a particularly strong polar vortex creating low pressure in the Arctic, and a faster jet stream—a core of very strong wind high in the atmosphere that can extend across the Atlantic—bringing stormier and very wet weather to the UK.

A stronger jet stream makes storms more powerful and its orientation roughly determines the track of the storm and where it affects.

Some aspects of climate change strengthen the jet stream, leading to more UK wind storms. Other aspects, like the higher rate of warming over the poles compared with the equator, may weaken it and the westerly flow of wind towards the UK.

Our high-resolution models predict more intense wind storms over the UK as climate change accelerates, with much of this increase coming from storms that develop sting jets.

Projections from global climate models are uncertain and suggest only small increases in the number of extreme cyclones. But these models fail to represent sting jets and poorly simulate the processes that cause storms to build. As a result, these models probably underestimate future changes in storm intensity.

We think that using high-resolution climate models, which can represent important processes like sting jets, alongside information from global models on how large-scale conditions might change, could give a more accurate picture. But the UK isn’t doing enough to prepare for the increasingly severe extreme weather already predicted.

Humanity has a choice in how much warmer the world gets based on the rate at which we reduce greenhouse gas emissions. [Talkshop comment: evidence-free assertion].

While more research will confirm if more extreme wind storms will hit the UK in the future, we are certain that winter storms will produce stronger downpours and more rain and flooding when they do occur.

Having recently advanced the idea that climate change was pushing UK storms further south, from Scotland to northern England, the BBC now features someone saying that the jet streams will move further north – for the same reason, i.e. climate change. Of course their chosen weather predicter is a net-zero enthusiast spouting the usual alarmist propaganda.

You just know that sooner rather than later the BBC will play its climate change (meaning humans in their book) card in an article about any kind of adverse or unusual weather conditions, even if only lasting a day or two, and sure enough…so predictable and tedious. They also conveniently forgot that in the ‘Great Storm’ of 1987 which felled an estimated 15 million trees in England alone, much of the damage was in southern England, northern France and the Channel Islands.
– – –
It is the untold story of the winter storms, says BBC News.

More than eight million trees have been brought down and many are now threatened by another two named storms bearing down on Britain.

Forest managers warn that already “catastrophic” damage will be made worse by Storms Dudley and Eunice.

There are warnings that the heating climate is making our weather more severe and unpredictable, and that management and planting strategies must adapt more quickly.
