How long is a day on earth? The obvious answer of 24 hours is accurate enough for many applications, says the Met Office blog.

But for those interested in GPS or deep space, then understanding the fluctuations of about one millisecond in the length of a day can be fundamentally important.

A team at the Met Office, led by Professor Adam Scaife, has calculated that these length of day fluctuations are predictable out to more than one year ahead and this is all to do with predicting the strength of atmospheric winds.

Weather forecasters faced unprecedented levels of trolling during this month’s extreme heat in the UK, according to leading figures in the industry – says BBC News.

The BBC’s team received hundreds of abusive tweets or emails questioning their reports and telling them to “get a grip”, as temperatures hit 40C.

BBC meteorologist Matt Taylor said he had never experienced anything like it in nearly 25 years working in weather.

The Royal Meteorological Society condemned the trolling.

Warm day in London


People in many parts of the world must be wondering what all the fuss is about, but Brits like to discuss their ever-changeable weather now and again…and again. Of course there’s now the added element of wild panic-mongering (see below) from the usual climate-obsessed suspects like the Met Office, trying to blame humans for natural events plus all the rest of their tedious hype. We’ve had hot days before, and some like to pay to find hotter ones on their travels, so let’s dial back on the shrill alarmism.
– – –
The Met Office has issued its first red warning for extreme heat, warning of a “potentially very serious situation” in parts of England, says ITV News.

The UK Health Security Agency has increased its heat health warning from level three to level four – a “national emergency.”

Level four is reached only when a heatwave is “so severe and/or prolonged that its effects extend outside the health and social care system”, according to the UK Health Security Agency.

Illness and death may occur even among the fit and healthy, and “not just in high-risk groups.”

In their computer model game they use the discredited RCP 8.5 formula that assumes a highly unlikely surface energy increase of 8.5W/m^2 by 2100 (not 2050). What’s the point?

You may have seen some of our forecasts that look a little further ahead than you would usually expect, says the UK Met Office.

Although they use the same graphics as our normal weather forecasts, we’ve been producing theoretical ‘forecasts’ for 2050 to look at what conditions we could expect to see in the UK if global greenhouse gas emissions continue to rise.

One of the greatest challenges with communicating the risks of climate change is how to show, in a relatable way, how changes in our atmosphere could impact the weather we experience on the Earth’s surface.

Warm day in London


In a word – no. One or two days of warm air blowing in from the continent to the southern half of the UK can’t prove anything. The forecast for Edinburgh, Scotland for example shows nothing over 20C in the next few days, so wailing about carbon dioxide and climate change is absurd. It shouldn’t need saying that weather isn’t going to be near seasonal norms all the time.

By the end of this week, parts of Britain will bake in temperatures of up to 34C, far hotter than normal June weather – but is climate change behind the soaring temperatures? – asks Yahoo News.

Met Office deputy chief meteorologist Dan Rudman, said: “Temperatures will continue to rise as we go through the week, becoming well above-average by Friday when many parts of the southern half of the UK are likely to exceed 30C and may even reach 34C in some places.”

“This is the first spell of hot weather this year and it is unusual for temperature to exceed these values in June.”

Why ‘track climate change’? We all know ‘tracking’ means using climate models to conjure up attribution numbers that can’t be questioned, except possibly by other climate models. How useful is that?

The Met Office will be reduced to its smallest size since the Second World War (says London Economic) if it is hit by a 20 per cent Civil Service staff cut, new figures have revealed.

Ministers have ordered every government department and agency to draw up plans to reduce their plans by at least one fifth, it has emerged.

According to the i newspaper, officials must also explain how they could cut staff numbers by up to 40 per cent if required.

Met backlash

The Met Office is expected to lobby ministers to preserve its current workforce, arguing that its role has never been more vital because of the need to forecast climate change.

It will also claim that its work pays for itself – because it is able to sell its services to commercial clients.

If the Met Office’s current workforce of just under 2,000 is slashed by 20 per cent, it will go below 1,600.

An amusing non-event. Many people in England are happy to spend time in warmer climates when they get the chance, as holiday choices show. The Met Office can waffle about greenhouses as much as it likes, but natural climate variation will take its course without reference to humans.

Forecasters have raised the temperature at which a heatwave is declared in several areas of England, reports BBC News.

The Met Office defines a heatwave as when an area experiences daily maximum temperatures meeting or exceeding a certain level for three days in a row.

Eight counties have had these limits raised by the forecaster by 1C.

Newly transcribed data from the Victorian era has ‘smashed’ current rainfall records, report experts at the Met Office and the University of Reading.

Heavy rainfall may be associated with flash floods and the modern-day battle against climate change, says the Daily Mail.

But a new study led by the Met Office and the University of Reading shows it’s nothing new – in fact, newly recovered data from the Victorian era has ‘smashed’ current rainfall records.

The signal that wasn’t found could be ‘masked’, researchers suggest. They expected ‘ongoing climate change’ to do something, but maybe it just wasn’t there? Cue more research.

A new Met Office-led study – reviewing evidence from previous scientific papers and climate models – reveals natural patterns of weakening and strengthening of ocean currents which influence the UK’s weather and climate.

In the North Atlantic lies one of the world’s largest climate mechanisms: a system of currents transporting relatively warm water from the tropics to the poles, with return currents at depth transporting colder, denser water further south.

The transport of heat to the North Atlantic keeps the UK’s climate warmer than other locations at our latitude, says the Met Office.

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.

Can Boris now explain the causes of the Little Ice Age and Medieval Warm Period, pre-dating industrial development?

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

A slide show that Prime Minister Boris Johnson says helped convince him on climate change has been revealed for the first time.

The slides used to “teach” him about climate science have been released after a Freedom of Information request by UK climate website Carbon Brief.

While Mr Johnson has urged action on climate change, he previously, as a journalist, expressed scepticism.

He called the presentation, given just after he took office, “very important”.

The “teach in”, as it was described in email correspondence, took place in the Cabinet Room of Number 10 Downing Street on 28 January 2020.

It was organised by the office of Sir Patrick Vallance, the government’s chief scientific adviser.

The briefing consisted of 11 slides showing key aspects of climate science and its impacts and the presentation was led by Prof Stephen Belcher, the chief scientist at the Met Office.

It is a bleak forecast even by the Met Office’s standards – the complete collapse of society leaving armed militias and criminal gangs to roam the land unchallenged, says the Daily Mail (via Climate Change Dispatch).

That is one of the doomsday scenarios set out in a report commissioned by the UK’s weather service to model the potential consequences of climate change.

The extraordinary report, called Shared Socioeconomic Pathways and developed for the Government-funded UK Climate Resilience Programme, sets out supposedly ‘plausible futures’ as a result of global warming.

One of those scenarios described by the authors is a surge in ‘Right-wing populism’, resulting in the collapse of ‘political and governance systems.’

Tan Hill Inn [image credit: North Yorkshire Weather]


The BBC says ‘Customers and an Oasis cover band are trapped at the Tan Hill Inn, near Keld, after heavy snowfall.’ It’s still only November, and the Met Office has forecast a mild winter. In fact parts of Scotland and the English North East also had wintry conditions with all kinds of damage going on.

A number of people had to sleep on the floor of Britain’s highest pub after Storm Arwen battered Yorkshire.

Twenty people, including an Oasis tribute band, were unable to leave the Tan Hill Inn in the Yorkshire Dales after being snowed in on Friday.

Elsewhere in the region, strong winds and snow have caused power cuts, fallen tress and travel disruption.

Warm day in London


Much talk of ‘extreme’ temperatures in UK cities in this Met Office blog post, although there aren’t any examples. There was a significant heatwave in 1976 and a few warmer than usual spells in the early 2000s, but talk of ‘frequency’ of such events seems premature to say the least. But the Met Office feels sure its computer modelling will prove to be accurate, and that weather trends are now largely determined by human activities.
– – –
With the recent COP26 focussing heavily on the chances of keeping global temperature rise below 1.5°C, it might be easy to forget that we are still committed to further climate change and a resulting increase in the frequency and intensity of heatwaves.

The impact of this will be felt increasingly in cities, where the majority of the world’s population now live, where much of our businesses, industry and infrastructure are concentrated, and where extreme temperatures are exacerbated by the urban heat island effect.

With many cities across the UK declaring climate emergencies, city councils and other decision-makers are asking how they can use increasingly refined and detailed climate projections to better understand the impact of extreme heat on urban communities.

Place bets now! Of course there could well be bits of both. The Met Office says its offering is ‘consistent with a warming climate’, but there was a very cold winter spell only 11 years ago, around the time of the last solar minimum.

Most know from bitter experience that meteorology is far from an exact science, but Britain’s two leading weather forecasting services have given completely contradictory predictions on what we can expect this winter, reports the Daily Mail.

The Government-run Met Office has forecast a mild winter, but the BBC’s service predicts it is likely to be cold and harsh.

Experts last night described the opposing long-range forecasts as unparalleled and they risk causing havoc for businesses such as energy suppliers, transport firms, supermarkets and airlines which rely on forecasts to plan ahead.

‘The higher global warming, the more rainfall’, say climate alarmists — then complain about droughts causing wildfires. Confused? Yes they are. Here, Ben Pile looks at the case of the UK .

Science Matters

Ben Pile writes at Spiked Climate policy, not climate change, poses the biggest risk to our daily lives.  Excerpts in italics with my bolds.

Firstly, Ben provides evidence for a reasonable person to conclude the weather and climate is doing nothing out of the ordinary.  Drawing on this year’s UK State of the Climate report:

But how significant are these changes really? Take, for example, the claim that the UK’s temperatures have increased. Leaving aside the possibility that land-use change thanks to the UK’s economic development might influence temperatures, the report offers this chart depicting 140 years of anomalies in UK and global annual temperatures:

graph-1-960x440-1

Though the chart clearly shows that UK temperatures have risen, there is substantial year-to-year variability – far greater in the UK than for the world as a whole – that might make us wonder how impactful this extra warmth really is.

Weather forecasting technology

Before they even build it, everyone knows what kind of answers the ‘climate supercomputer’ will be required to produce. These will then be presented as evidence of the pre-conceived climate theories, which will be tagged as ‘science’ and everyone will be expected to be impressed.

The Met Office will work with Microsoft on a supercomputer which will help model climate change, says BBC News.

They say it will provide more accurate weather forecasting and a better understanding of climate change.

The UK government said in February 2020 it would invest £1.2bn in the project.

Of course they wouldn’t want to incur the wrath of climate alarmists who blame humans for the weather, since they’re closely allied with them and believe carbon dioxide, although fine for vegetation and fizzy drinks, is somehow ‘unclean’.

Bosses at the Met Office are said to want to house half a £1.2 billion new supercomputer system outside the UK, The Mail on Sunday can reveal.

Well-placed sources say the forecasting set-up will be the most advanced in the world, but there are fears that the huge amount of energy it uses will torpedo the service’s public stance on fighting climate change.

‘The electricity this thing will use will be so massive that they want to house half of the technology somewhere like Norway where they have cleaner energy,’ one insider said.

Back in 2016, the UK MET Office’s median projection to the start of 2021 forecast a global temperature temperature anomaly of 1.4C above their 1850-1900 “Pre-Industrial” baseline. Their recently published five year model projection (rightmost blue blob on graph), shows a 2021 median anomaly 0.35C lower, at 1.05C.

Their HADcruT 4GL temperature time series (data since 2016 added in red on graph) shows a linear trend of +0.09C/semi-decade for the last 50 years. CO2, by far the biggest forcing in their model, is still rising in lockstep with the 50 year temperature trend. What could have caused this remarkable downward step change in their model output?
