No telling how much more snow coming for Sierra Nevada

Image credit: tahoeskiworld.com

They’re calling it “the winter that just doesn’t want to end” as the figures close in on the all-time record for the area. Another atmospheric river is imminent. Records show that ‘several of the snowiest winters logged at least one-fourth of their season total after March 15’.
– – –
No one really knows how much snow fell on the infamous Donner Party when the pioneers were trapped atop the Sierra Nevada for months and dozens died near Lake Tahoe in the winter of 1846-47, says Phys.org.

But this season has now etched its way into the history books as the second snowiest in the 77 years of record-keeping at the Central Sierra Snow Lab—more than 56.4 feet (677 inches, 17.2 meters) with no end in sight.

And there’s still a chance it could surpass the record of 67.7 feet (812 inches, 20.6 meters) set in 1951-52 when more than 200 passengers on a San Francisco-bound luxury train from Chicago were stranded for three days near Donner Pass west of Truckee, California.

Over the weekend, the “winter that just doesn’t want to end” as the National Weather Service in Reno put it, topped the previous No. 2 record of 55.9 feet (671 inches, 17 meters) set in 1982-83.

Concern grows over rich nations controlling sunlight

Say hello to an umbrella term for outlandish climate intervention schemes, or maybe scams: SRM (solar radiation management).
– – –
Radical climate interventions — like blocking the sun’s rays — could alter the world’s weather patterns, potentially benefiting some regions of the world and harming others, says E&E News.

That possibility, climate scientists say, means any research on such methods must consider those risks and involve the countries that already bear the greatest impacts from a warming planet.

“If you’re actually talking about actively deploying technologies to alter the climate, then you need to engage all of us in the discussion,” said Andrea Hinwood, chief scientist at the United Nations Environment Programme in Nairobi, Kenya. “And that means those who are the most vulnerable to these effects need to be able to have a say.”

UK weather: The atmospheric ‘seesaw’ partly responsible for this week’s cold snap

Meteorology time. Why the ‘partly’ in the headline? Climate change pokes its nose in at the end of the article, but all that’s offered is uncertainty.
– – –
The “seesaw” is bordered by a high-pressure area west of Portugal and a low-pressure area centred over Iceland.

When the balance changes, so does the weather, says Sky News.

An atmospheric “seesaw” is partly responsible for the snow that much of the UK will likely see this week.

One in Five Germans Fear Green Agenda Will Destroy Their Jobs

Needless to say, high energy prices and job insecurity isn’t what workers wanted in exchange for obscure future benefits. But the country’s Green Party says in effect ‘like it or lump it’. Welcome to the effects of manic climate obsessions.
– – –
A survey done by the German Trade Union Confederation has reportedly found that one in five employees now fear for the future of their jobs as a result of the country’s push for green agenda measures aimed at curbing climate change, says Breitbart.

It is the latest piece of evidence showing how the European Union’s leading economy is struggling with its own carbon emission goals, with the price of energy soaring over last year as renewable energy sources are unable to fill the hole left by missing Russian gas and deliberately scrapped nuclear energy.

The surging price of electricity and home heating is not all that Germans are worrying about, though, with a report by Die Welt claiming that around 20 per cent of the German workforce now feel the country’s green push could endanger their employment.

Why do Earth’s hemispheres look equally bright when viewed from space?

Has the mystery been solved?
– – –
When looking at the Earth from space, its hemispheres – northern and southern – appear equally bright, says EurekAlert.

This is particularly unexpected because the Southern Hemisphere is mostly covered with dark oceans, whereas the Northern Hemisphere has a vast land area that is much brighter than these oceans.

For years, the brightness symmetry between hemispheres remained a mystery.

Study finds exchange of carbon between ocean and atmosphere ‘is much more complicated than we first thought’

Photosynthesis springs a surprise. Why not find out what nature is doing before accusing humans of altering the global climate?
– – –
A new study demonstrates the important role of a common group of marine calcifying phytoplankton (coccolithophores) in the regulation of carbon dioxide (CO2) concentrations in the atmosphere, says Phys.org.

The ocean has removed roughly a third of the CO2 released by humans since the Industrial Revolution.

It is one of the largest sinks of anthropogenic CO2 and the largest reservoir of carbon that can easily exchange with the atmosphere on our planet.

Understanding the processes that control the exchange of carbon between the ocean and atmosphere is key for projecting the future effects of carbon dioxide on climate change, ocean acidification, marine organisms, and society.

European summer droughts since 2015 ‘most severe in centuries’, but multi-year droughts also happened in the past

Freighter passing a sandbank on the Rhine river [image credit: worldcargonews.com]

Mixed messages from climate research here. In between evidence-free waffle about ‘potential’ human influence, they report that severe drought spells are nothing new in Europe, implying climate cycles of some sort. This means attribution of such drought to human causes is debatable, as the article admits.
– – –
The 2015–2018 summer droughts have been exceptional in large parts of Western and Central Europe over the last 400 years, in terms of the magnitude of drought conditions.

This indicates an influence of man-made global warming, claims Phys.org.

However, multi-year droughts have occurred frequently in the 17th and 18th century, although not as severe.

This is the result of a new study in the journal Communications Earth & Environment.

Phys.org Claims Atmospheric Rivers And Hurricanes Getting Worse. Data Says No

Credit: NOAA

Climate modellers claim to be able to prove weather is getting worse than ever before. They seem to have a method problem.
– – –
A recent article at Phys.org, originally published by the Chicago Tribune, says that climate change is behind the recent atmospheric river events in California, as well as an alleged increase in Category 4 and 5 hurricanes.

This is false, says Linnea Lueken @ Climate Change Dispatch.

Atmospheric rivers are a natural part of the West coast’s climate, and neither historic data nor recent trend data indicate that the frequency or severity of those events is increasing.

Likewise, there has been no increase in major hurricanes over the past hundred years of global warming.

Why have there been no named winter storms this year? – BBC

Bring on the loaded questions, such as ‘How does climate change affect windstorms?’ The BBC casts around for suspects, like La Niña and meandering polar jet streams, but it’s all inconclusive. Are the ‘extreme weather’ climate obsessives feeling deprived?
– – –
By February, the UK would normally have had around three storms given names by the Met Office – just like Arwen, Barra and Callum, says BBC News.

But so far this autumn and winter, there hasn’t been a single one.

Weather patterns have been calmer across the Atlantic and towards northwest Europe. But why?

Science Writer Warns Ozone Hole Recovery Claims Likely Premature, Too Optimistic

Credit: earthhow.com

Is there a role for natural climate variation here, and if so, what is going on?
– – –
Claims by a UN-backed expert panel that the ozone layer is healing and headed to full recovery may be premature and overly optimistic, Net Zero Watch’s Science Editor Dr. David Whitehouse has warned.

Any internet search will find hundreds of news stories announcing that the ozone hole over the Antarctic is slowly filling and that by about the middle of this century mankind’s vandalism of this natural atmospheric layer will have been remedied, says Benny Peiser via Climate Change Dispatch.

The ozone hole has become an icon of anthropogenic interference in the natural world — and a hopeful signpost that there is a way back. But is the ozone hole healing? Not by as much as many headlines suggest, it would appear.

Earth’s inner core rotating slower than surface, study suggests

Some uncertainties with this topic. Researchers here propose a 70-year cycle, but other theories say 20-30 years, or even no cycle at all.
– – –
Earth’s inner core, a hot iron ball the size of Pluto, has stopped spinning faster than the planet’s surface and might now be rotating slower than it, research suggested on Monday.

Roughly 5,000 kilometers (3,100 miles) below the surface we live on, this “planet within the planet” can spin independently because it floats in the liquid metal outer core, says Phys.org.

Exactly how the inner core rotates has been a matter of debate between scientists—and the latest research is expected to prove controversial.

Rain stopped York council’s £500k electric bin lorries working

Risky business [image credit: safetysource.co.nz]

York is a notoriously flood-prone place and these wagons under-performed in a big way, restricting themselves to cricketing weather. The costly attempt to help save the planet by adopting net-zero climate dogma thus faltered. The ‘wrong type of weather’ excuse used to refer to UK trains, but now it’s moved on.
– – –
Two electric bin lorries bought by City of York Council in a bid to cut carbon emissions were unable to operate when it rained, it has emerged.

Rain caused the wagons to be taken off the city’s roads for up to 26 days a month several times last year, reports BBC News.

The vehicles stopped working for a combined total of 481 days between January 2021 and November 2022.

The council bought the vehicles in 2020 as part of its drive to achieve net zero emissions by 2030.

What uncertainties remain in climate science?

How long is a piece of string? The waffle about ‘climate deniers’ and ‘reputable scientists’ is a waste of time. There will always be known unknowns and unknown unknowns – that’s science.
– – –
[Last paragraph of the article only]
The uncertainties in climate science that remain are not a justification for not acting to slow climate change, because uncertainty can work both ways: Climate change could prove to be less severe than current projections, but it could also be much worse, says State of the Planet @ Phys.org.

Talkshop comments:
— ‘Climate change could prove to be less severe’ – or not related to human activity, or not severe at all
— ‘Could also be much worse’ – ‘could’ be this or that, i.e. they can only speculate about the future, but nevertheless demand ‘action’ now

Global ‘Stilling’: Is Climate Change Slowing Down the Wind?

Windy enough today?

This recent Yale Environment360 article came into focus today when Sky News headlined with: Future of renewable energy in balance as UK suffers wind drought – with ‘global stilling’ to come. Ironically, climate theory has it that warming will happen and will reduce wind speeds over the decades ahead. According to one expert (says Yale), a 10 percent decline in wind speeds would actually result in “a 30 percent drop [in output], and that would be catastrophic.”
– – –
Last year, from summer into fall, much of Europe experienced what’s known as a “wind drought,” says Yale.

Wind speeds in many places slowed about 15 percent below the annual average, and in other places, the drop was even more pronounced.

It was one of the least windy periods in the United Kingdom in the past 60 years, and the effects on power generation were dramatic.

Wind farms produced 18 percent of the U.K.’s power in September of 2020, but in September of 2021, that percentage plummeted to only 2 percent. To make up the energy gap, the U.K. was forced to restart two mothballed coal plants.

UK National Grid avoids emergency blackout measures in supply scramble

Winter isn’t even here yet. But with a colder weather spell plus low wind speeds around the corner, trouble is already brewing for renewables-infested electricity supplies. Somehow it’s linked to problems in France and/or Ukraine, according to this report.
– – –
National Grid opted against implementing emergency measures to stave off blackouts tomorrow, escalating fears of supply shortages this winter, reports City A.M.

The company’s electricity system operator (NGESO) revealed this morning that it was considering activating its Demand Flexibility Service (DFS) for the first time to help reduce the risk of blackouts on Tuesday.

This follows power outages in France and a decline in renewable energy generation over the past week.

Scientists discovered a river longer than Thames beneath the Antarctic ice sheet

Interesting, but too many uncertainties at this time to reach any firm conclusions. The river system is ‘beneath kilometers of thick ice’.
– – –
Scientists at Imperial College London, the University of Waterloo, Canada, Universiti Malaysia Terengganu, and Newcastle University have discovered an unexpected river under the Antarctic ice sheet, says Tech Explorist.

The discovery of this 460km-long river shows the ice sheet’s base has more active water flow than previously thought, which could make it more susceptible to changes in climate.

The river is believed to affect the flow and melting of ice, contributing to the acceleration of ice loss during climate warming.

Sea-level rise in the Mediterranean Sea branded ‘staggering’, due to scientists ‘using a vital new method’

Credit: OH 237 @ Wikipedia

Vastly higher? Enormous? Staggering? – should we be shocked? No, because none of these words from the article below appear in the study itself, which notes: ‘We find that, between 1960 and 1989, sea level in the Mediterranean fell’. It then ‘started accelerating rapidly’. The study also admits: ‘The relative contributions from sterodynamic changes (i.e., changes in ocean density and circulation) and land-ice melting to this recent increase in the rate of Mediterranean sea-level rise remain unclear.’ Looks like the press release resorted to colourful language.
– – –
Scientists from the National Oceanography Centre (NOC) have discovered a substantial rise in sea-levels in the Mediterranean Sea, using a vital new method to measure changes in sea-level, says the NOC.

The study, published in Journal of Geophysical Research: Oceans, demonstrated that sea levels in the Mediterranean Sea have risen at vastly higher rates over the past 20 years compared to the entirety of the 20th century.

The study revealed that sea level in the Mediterranean Sea increased by about 7cm in the period 2000–2018.

Previous changes in sea-level rise in the Mediterranean Sea have been highly unpredictable due to limited observational data but using this latest method, scientists analysed sea-level data from tide gauges and satellites to reveal an enormous increase as a result of ocean warming and land ice-melt.

Miyake event radiation deluges still unexplained as solar flare theory questioned

When they say ‘sudden’ they don’t mean short-lived. The report notes that ‘some of the events, unlike the brief flashes we recognize as solar flares, lasted for one or two years’. Only a handful of these so-called ‘cosmic barrages’ have occurred in the last 9000 years or so, according to the data.
– – –
One of the events was 80 times more powerful than the strongest solar flare ever recorded, says LiveScience.

A series of sudden and colossal spikes in radiation levels across Earth’s history could have come from a series of unknown, unpredictable and potentially catastrophic cosmic events, a new study has revealed.

Named Miyake events after the lead author of the first study to describe them, the spikes occur roughly once every 1,000 years or so and are recorded as sudden increases in the radiocarbon levels of ancient tree rings.

The exact cause of the sudden deluges of radiation, which periodically transform an extra chunk of the atmosphere’s nitrogen into carbon sucked up by trees, remains unknown.

Vapour buoyancy flaw leads to inaccurate simulations of cloud distributions in climate models, study finds

Tropical scene

The researchers say ‘climate models often differ on the precise degree of future warming, largely due to their representation of clouds.’ For decades we’ve been told to believe variations in carbon dioxide are the key to any future warming, but climate model forecasts have been unable to deliver the hoped-for precision. Predicting future cloud variations looks like a tall order.
– – –
Quick Summary

— Study adds a missing piece to the climate science puzzle of simulating clouds.
— Lightness of water vapor influences the amount of low clouds.
— Some leading climate models don’t include this effect.
— Including vapor buoyancy into climate models helps improve climate forecasting.

Clouds are notoriously hard to pin down, especially in climate science, says UC Davis.

A study from the University of California, Davis, and published in the journal Nature Geoscience shows that air temperature and cloud cover are strongly influenced by the buoyancy effect of water vapor, an effect currently neglected in some leading global climate models.
