Piers Corbyn challenges Top Meteorology professor to provide observational evidence of so-called man-made ‘climate change’.

Piers at the Electric Universe conference 2014

On Mon 16th May at the annual Imperial College Lighthill Lecture* – this year by Professor Sir Brian Hoskins on ‘Predicting Weather and Climate’ – WeatherAction astrophysicist Piers Corbyn, First class Physics graduate from Imperial College, challenged Sir Brian to produce observational evidence of CO2 driving changes in Climate     * http://www.imperial.ac.uk/fluids-cdt/about/lighthill-lectures/

In the discussion section of the event Piers thanked Sir Brian for his superb presentation on meteorology concepts and processes and said that however he had difficulty with his comments on Carbon dioxide and climate. Piers said

“The problem you have is that there is no observational evidence that world temperatures follow CO2 levels but the relationship is the other way. The trace gas CO2 follows temperatures with delays of some centuries because the relative partition between CO2 in the air and in the sea – which holds 50 times more CO2 than the atmosphere – is controlled by Sea (surface) temperatures (under Henry’s Law) and I challenge you to provide evidence of your claims”

Sir Brian said there was evidence in the UN IPCC reports. 

Piers said “No, there is no evidence in those reports only opinion. We must rely on evidence not opinion”. Sir Brian said he agreed evidence not opinion was required. Piers said Yes we need to see a graph of observational evidence please send evidence to piers@WeatherAction.com ”

Afterwards Piers gave his business card with email to Sir Brian.

Further Comment from Piers: We will keep WeatherAction site updated on any responses. Sir Brian’s CO2 and Climate claims did not follow in any way from the main part of his presentation on world weather description parameters and meteorological concepts and processes. 

His claims that Man’s CO2 lasts thousands of years and that this is causing Ocean acidification are factually false (but we didnt have time to discuss these). For a start IF Man’s CO2 lasts thousands of years in the atmosphere it cannot also be in the sea causing so-called ‘acidification’. The fact is that because the sea holds 50 times more CO2 than the all even if all atmpsheric CO2 went into the sea – let alone man’s 4% contribution to it – which anyway it cannot because of Henry’s partition Law, it could potentially have only a trivial effect which is further suppressed by the ‘buffer solution’ nature of the sea. 

There is a dynamic balance between CO2 in the sea and air and on average half any atmosperic@ CO2 will enter the sea in a few years and CO2 is similarly releaased from the sea at close to the same rate.

Piers Corbyn – “World weather is now developing faster into grim new era”

ARCTIC SEA ICE –Persistence Puzzles

Such a good read…as always

Sunrise's Swansong

The real news, (or at least the news to me), this summer has been the persistence of the general area of low pressure I dubbed “Ralph”, at the Pole. According to the general theory of atmospheric circulation, which has Hadley, Ferrel and Polar Cells neatly arranged between the equator and the poles, the North Pole should be an area of descending air, and air pushing down makes high pressure.

Polar High image_649

It doesn’t make sense to have low pressure ,  indicating rising air, sitting in the middle of a cold, ice-covered sea surrounded by hot, sun-baked tundra. Yet it continues to happen. How can it be?  Shouldn’t the air be rising over the hot places and sinking over the cold?

All I can do is watch and observe, for one thing I have come to understand is that the weather will not bow to me, and is not cowed by the brilliance…

ARCTIC ALARMISM UPDATE : Cambridge University Professor Accused Of “Crying Wolf”


“In the end, it will just melt away quite suddenly. It might not be as early as 2013 but it will be soon…” – Prof. Paul Wadhams 2007 (‘Arctic will be ice free by 2013’ – BBC)

“greater than even chance” that the North Pole could be ice-free for the first time next month. – Prof. Paul Wadhams 2016 (‘A Farewell to Ice‘)

Arctic ice “may well disappear” this September – Prof. Paul Wadhams 2016



Climate experts at war over prediction of ice-free Arctic

  • The Times
  • 11:30AM August 25, 2016

A Cambridge University professor has been accused of “crying wolf” by predicting the imminent disappearance of Arctic ice.

Peter Wadhams has been criticised by scientists who fear that he could undermine the credibility of climate science by making doom-laden forecasts.

He repeatedly predicted that the Arctic would be “ice-free” by last summer

Earthquake kills at least 120 in central Italy

Drone footage: Italian Fire Brigade

The BBC reports the death toll as at least 250. Utterly devastating for this small community.

Earthquake was ‘long and ugly’

Local residents have been speaking of their shock at the scale of Wednesday’s earthquake. 

Silvano Parla, from the town of Arquata del Tronto, said earthquakes were felt regularly in the area, but added: “I have lived through many earthquakes in the years – every seven to eight years there is an earthquake here. But one like this one, never. It was long and ugly.”


“At least 120 people have been killed and 368 injured in an earthquake that hit a mountainous area of central Italy, PM Matteo Renzi has said.”



BBC now reporting at least 60 dead. Very sad.



A magnitude 6.2 earthquake has struck central Italy, leaving at least 37 people dead and 150 missing, as rescuers search for survivors.

Many of the dead were in the village of Pescara del Tronto which was levelled to the ground and there were fears the number of casualties could rise.

Much of the town of Amatrice was reduced to rubble and a family of four were feared dead nearby in Accumoli.

The quake hit at 03:36 (01:36 GMT), 100km (65 miles) north-east of Rome.

Although it struck at a shallow depth of 10km, its intensity was compared to the Aquila earthquake in April 2009 in which 309 people died. The epicentre was around Accumoli where several people died.

Some buildings in the capital shook for 20 seconds as the quake struck the regional border area of Umbria, Lazio and Le Marche. It was felt from Bologna in the north to Naples in the south. Some 80 aftershocks have been reported since…

Study reveals meteorological impact of 2015 solar eclipse

A pioneering study by the University of Sheffield has revealed the meteorological impact of the 2015 UK solar eclipse across three countries. 

The analysis of high-frequency surface air temperature, mean sea-level pressure, wind speed and direction and cloud-cover data from the  of 20 March 2015 from the UK, Faroe Islands and Iceland, published today (Monday 22 August 2016), sheds new light on the phenomenon.

The research, led by Professor Edward Hanna, of the University of Sheffield’s Department of Geography, used data from 76 UK Met Office weather stations, 30 weather stations in the Faroe Islands and 148 stations in Iceland.

It found:

  • There was a statistically significant mean UK temperature drop of 0.83±0.63 degrees Celsius, which occurred over 39 minutes on average, and the minimum temperature lagged the peak of the eclipse by about ten minutes.
  • For a subset of 14 relatively clear (cloudy) stations, the mean temperature drop was 0.91± 0.78 (0.31±0.40)degC, but the mean temperature drops for relatively calm and windy stations were almost identical, indicating that cloud cover has a much greater effect than wind on the air temperature’s response to an eclipse.
  • The average wind speed dropped significantly by 9 per cent on average during the first half of the eclipse, in line with previous studies.
  • There was no detectable effect of the eclipse on the wind-direction or barometric pressure time series, and therefore we can discount any localised change in air circulation over Britain (for example, the much-fabled ‘eclipse cyclone’) during this event.
  • Similar changes in air temperature and wind speed were observed for Iceland, where conditions were generally clearer, but there is no evidence of the eclipse cyclone.
  • In the Faroes, there was a much more muted meteorological signature.

The study represents a successful co-operation between the University of Sheffield, the UK Met Office, the Icelandic Met Office, the Danish Meteorological Institute and the Faroe Islands Met Service.


The North Atlantic: Ground Zero of Global Cooling

Watts Up With That?

Guest essay by David Archibald

The warning signs have been there for some time now – persistent failures of the wheat crop in Norway for example. The North Atlantic is cooling. The cooling trend was evident at the time of an expedition to investigate this phenonemon three years ago. The rate of cooling has now steepened up since then based on the latest data collated by Professor Humlum of the University of Oslo. From that data set, this graph shows the heat loss since 2004 for the top 700 metres of the water column:


Figure 1: Monthly heat content anomaly in the uppermost 700 metres of the North Atlantic

As Figure 1 show, North Atlantic heat content peaked in 2004. The decline since the peak has been steeper than the rise. What would be the reason for 2004 being the peak year? Part of the answer may be that 2004…

Rock star-scientist Brian Cox confused on more than global temperatures


By Paul Homewood

Jennifer Marohasy launches a scathing take down of overrated TV scientist, Brian Cox:

Celebrity physicist Brian Cox misled the ABC TV Q&A audience on at least 3 points-of-fact on Monday night. This is typical of the direction that much of science is taking. Richard Horton, the current editor of the medical journal, The Lancet, recently stated that, “The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue.”
