Whither global warming? Not Harvard

February 10, 2015

Climate is an integral of local weather over time and space . If climate change (specifically global warming) does not show up as weather then it does not exist. From The Harvard Crimson:

Snow on Plympton

A student walks down Plympton St. on Monday evening, flanked by growing piles of snow. – Harvard Crimson

 As many Harvard schools cancel classes Tuesday for the third time in as many weeks — only its fourth snow day since one in 1978—administrators have begun to consider ways to compensate for lost instructional time. ……. 

……. Harvard has had only five snow days in the last four decades; before this semester, the only other two were in 2013 and 1978. …..

 …….. Between 2013 and 2015, Harvard has seen four of its five snow days in four decades. In 1977, before a snow day in 1978, former Dean of Students Archie C. Epps III joked that, “Harvard University will close only for an act of God, such as the end of the world.”

It wasn’t a joke.

Clearly snow days are to be taken as an Act of God where I take “God” to represent the natural variations in weather (and climate) which are beyond the wit of man to influence. But it does take some imagination for a winter snow storm to be equated to the “end of the world”. A summer snow storm might better qualify!

Swedish forest fire largest in recent times but a tiny fraction of pre-industrial times

August 6, 2014

Västmanland, Sweden

Increasing humidity and some rain has limited the spread of the largest forest fire which has been ongoing for 7 days in the northern part of Västmanland in Sweden. One person has been found dead  and some 4,000 homes were evacuated a few days ago. Some of those evacuated can now begin to return.

The fire followed 2 weeks of quite warm weather over the entire country with temperatures around 30ºC (high, but not unknown at this times of year and no records were broken).

What became quite clear was that the equipment available to the emergency services was sadly lacking. Three successive governments have taken the easy opportunity of cutting emergency services and there were just no helicopters or planes available in the country for containing the fire. One was requested from Italy yesterday but could not be sent. Another from France is only arriving today. Needless to say they will probably arrive after the point at which they could have done the most good. If it continues to rain today, they will be irrelevant.

Before 1850, fires consumed 250 times larger areas of forest in Sweden than today. It has been the “industrial harvesting” of forests which has drastically reduced the incidence of forest fires. And it has been the complacency brought about by the low incidence of forest fires which has led to a reduced preparedness to fight the fires when they do occur.

The climate alarmists (and there are many of them in Sweden) have not been slow to blame the fire on global warming. A little depressing to hear people so ready to switch off all their rational faculties and parroting what sounds like a climate catechism.!!

But a few sane voices can also be heard.

Swedish Radio:

Two hundred years ago forest fires raged much more freely in Swedish forests. It was when humans began to harvest the forest that fires reduced.

“Swedish forests burned much more in historical times”  says Bengt-Gunnar Jonsson, professor of plant ecology at Mid- University. “Just a few hundred years ago one percent of Swedish forests burned each year. 250 thousand hectares every year. Today only about a thousand acres are lost to forest fires every year“.

Bengt-Gunnar Jonsson sees three separate  eras of fires in the Swedish forests. From prehistoric times to the seventeenth century there were only a few but very large fires. From the seventeenth century until the mid-nineteenth century, when the population increased and people started residing there, the number of fires increased but they were smaller. In the mid-nineteenth century industrial forestry started and the number of forest fires declined sharply. There was a dramatic shift to a landscape where people – rather than fire – harvested the trees.

“Even the very first people in Sweden might have affected how much it burned in the woods”, according to Bengt-Gunnar Jonsson. “Although we have observed fires for several thousand years, we cannot really explain effects of climate and lightning. Many argue that even the ancient fires had a human footprint. It could be that humans have influenced fire history since the ice retreated”.

Climate and the butterfly in Brazil

June 22, 2014

You may think that the weather outside your window is a consequence of the prevailing climate. But that would be the cart before the horse. Without weather there is no climate.

Climate is to weather as evolution is to reproduction.

Evolution is just a label given to the result of many, many individual survival and reproduction events. Evolution is not a “force” which directs who will survive and who will not or which individuals will reproduce and who will not. Evolution is then the name we give to the resultant changes in the genetic make-up of species as individuals of that species survive and reproduce (or fail to reproduce where  the species goes extinct). The survival and reproduction of individuals changes as the environment they live in changes. Evolution is thus the global, net result of the millions of successful, local, individual matings, and of the many more millions of failures to reproduce. Natural selection is merely a record of those that manged to survive and reproduce and thereby “deselected” all the failures. Without environmental change first causing a change in which individuals survive and then reproduce, there can be no evolutionary change (except due to random mutations).  Similarly there is no great driving force called climate which determines the weather outside your window. Climate is the label we give to the summation of all the local weathers in a region or around the globe as being the climate of that region or of the world. Just as resulting evolution and evolutionary change is impacted by the local survival or failure of a species, so is resulting climate impacted by weather and by changes to local weather patterns. Climate is a calculated result, an average, of  myriads of local weather events

Without reproduction and consequent genetic change there is nothing to be called evolution. There is no evolutionary change if a species is genetically static – if it’s surroundings and its growth are unchanged.  Similarly there is no climate change if local weather patterns remain static. And without individual events of local weather there can be no average to be called climate.

The weather we each experience locally outside our windows covers a very wide range. Within a few minutes, on any day of the year we can experience temperature changes of  5 – 10ºC as clouds appear or it starts blowing or if it rains or if it snows. Winds can vary from virtually still upto over 100km/h in the midst of a storm. Every single day we see a change of around 10ºC between day and night. Over a period of a week it would not be unusual to have a temperature change of even 20ºC. Over a year a temperature variation of 60ºC (+35ºC on the warmest day to – 25ºC on the coldest) could be expected at my latitude.

Politically correct “climate science” today takes it for granted that any unpleasant warming of the earth, or uncomfortable cooling of the earth, or increased frequency of storms, or copious amounts of rainfall and any resulting flood, or no rainfall and any resulting drought, or any unduly severe hurricanes is – by virtue of its unpleasantness – due to man-made climate change. And man’s evil influence is all manifested by the emissions of carbon dioxide from fossil fuel combustion and the atmospheric concentration of carbon dioxide!

But in the meantime it is mid-summers day and a cloud has passed over the sun. And when the cloud has passed I will feel a lot warmer than by increasing the carbon dioxide around me!!!!

In the 1960’s Edward Lorenz developed his chaos theory and in 1972 gave his famous talk questioning if the flap of a butterfly’s wings in Brazil could set off a tornado in Texas. (Lorenz Butterfly 1972).

Lorenz 1972

Lorenz 1972

Without reproduction there is no evolution and without local weather there is no climate.

Blaming fossil fuel combustion for climate change is like blaming one poor butterfly in Brazil and ignoring every other bird and insect flapping its wings.


Minus 42°C – back to a normal winter after a mild Christmas

January 21, 2014

This Christmas was the mildest in about 10 years but things are getting back to normal winter conditions. We have now had plenty of snow and are currently going through another cold wave. In the north of Sweden temperatures dropped to minus 42°C.

The usual chaos on the roads and with train traffic. My back hurts – as usual – after clearing snow from our garden path. Its only minus 12°C at the moment but thank goodness for electricity.

It’s just weather and we may even come up – temporarily – to a high of 0°C sometime next week. But the days are getting longer and summer is surely on its way.

The Local

Sunday night saw the lowest temperature of the season when Karesuando in the far north hit -41.9°C, but the mercury didn’t stop there.

“It was -42.5°C in the early morning hours,” said Lisa Frost, meteorologist at Sweden’s weather agency SMHI. “The high pressure system is still hanging over northern Scandinavia. These temperatures are here to stay for the coming days.

The lunar nodal cycle and its effects on climate

July 27, 2013

A paper has just been published in the International Journal of Climatology showing that the lunar nodal cycle influences “the low-frequency summer rainfall variability over the plains to the east of subtropical Andes, in South America, through long-term sea surface temperature (SST) variations induced by the nodal amplitude of diurnal tides over southwestern South Atlantic (SWSA).”

Eduardo Andres Agosta, The 18.6-year nodal tidal cycle and the bi-decadal precipitation oscillation over the plains to the east of subtropical Andes, South America, International J of Climatology, DOI: 10.1002/joc.3787

Abstract: This work shows statistical evidence for lunar nodal cycle influence on the low-frequency summer rainfall variability over the plains to the east of subtropical Andes, in South America, through long-term sea surface temperature (SST) variations induced by the nodal amplitude of diurnal tides over southwestern South Atlantic (SWSA). In years of strong (weak) diurnal tides, tide-induced diapycnal mixing makes SST cooler (warmer) together with low (high) air pressures in the surroundings of the Malvinas/Falklands Islands in the SWSA, possibly through mean tropospheric baroclinicity variations. As the low-level tropospheric circulation anomalies directly affect the interannual summer rainfall variability, such an influence can be extended to the bi-decadal variability present in the summer rainfall owing to the nodal modulation effect observed in the tropospheric circulation. The identification of the nodal periodicity in the summer rainfall variability is statistically robust.

The lunar nodal cycle is not something that is very well known but it is another celestial cycle which is clearly not to be ignored. Naturally the IPCC takes no notice of solar cycles, planetary cycles or lunar cycles and all these are lumped into what could be considered “natural variability”.

(Sourced from Wikipedia)

The lunar orbit is inclined by about 5 degrees on the ecliptic. The moon  therefore can lie up to about 5 degrees north or south of the ecliptic. The ecliptic is the plane of the apparent path of the Sun on the celestial sphere, and is coplanar with both the orbit of the Earth around the Sun and the apparent orbit of the Sun around the Earth.

Lunar eclipse orbital diagram: wikipedia

The lunar nodes precess around the ecliptic, completing a revolution (called a draconitic or nodical period, the period of nutation) in 6793.5 days or 18.5996 years.

The effects of the 18.6 year lunar nodal cycle on climate on tides and geological sediments and on weather and climate have long been of interest (though not apparently for the IPCC).

Nanocycles Method is the English translation of the title of a book published in Russian by Professor of Geology S Afanasiev of Moscow University in 1991,ISBN 5–7045–0109–0.

From “Nanocycles Method” by S Afanasiev, 1991

The lunar node cycle, which is presently 18.6 years, affects the rainfall on a 9.3 year cycle and this shows up as varying thickness layers of deposits, or varves, in geological formations. 

However the moon’s orbit is gradually getting larger over time and so its period is slowing down. The rate of movement of the nodes is also decelerating and Prof Afanasiev has determined the accurate nodal cycle period for the whole of the last 600 million years.

The cycle of the lunar node is important in affecting the weather because it plays a part in determining tides in the atmosphere, oceans and solid body of the earth. The atmospheric tides affect rainfall which in turn affects river flows and hence the deposition of geological varves, or annual deposits in geological layers. ….. 

At the present time, with a nodal cycle of 9.3 years, successive nodal cycles begin 0.3 years later in the seasons each cycle. Therefore after 3 or 4 cycles the nodal cycle start return to the same time of year again. The average period of the cycle when the nodal cycle comes at the same time of year is 9.3/0.3 or 31 years. Specific occurrences of nearly the same season, within 0.1 year, will occur after 28, 65 and 93 years and so on. 

…. Because the lunar nodal cycle period has changed from 9.147 years to 9.298 years in the last 1.0 million years, the secondary cycle has varied from 62.12 years to 31.21 years. If this cycle can be measured in a deposit to an accuracy of 1 year then it allows the dating of the deposit to an accuracy of +/-0.03 million years.

A small selection of papers dealing with the effects of the 18.6 year lunar nodal cycle is given below:

Piers Corbyn: Mini Ice Age is upon us and the CO2 story is over

March 15, 2013

Piers Corbyn is not the most popular figure in “scientific” circles and is probably detested among “main-stream” weather pundits.  He just seems to get his forecasts right more often than conventional weather-men do, but he does not reveal his methods and this causes many to dismiss him as a lucky charlatan. They prefer to consider him an astrologer rather than a colourful but serious astrophysicist who might actually be considering the correct parameters. That he might also be making some money from his commercial weather forecasts is even more galling to some.

Weather Action: Our forecasts, which have independently proven peer-reviewed significant skill – unlike all others in the field – are based on our revolutionary Solar-Lunar-Action-Technique (SLAT) which is increasing in scope and skill as our researches advance.

But I like that he gives due importance to solar effects. And his track record in forecasting cannot be denied and I am inclined to take him rather seriously in spite of his  use of horribly garish colours in his presentations. His results if not his methods are getting some attention in Parliament.

Climate Realists have his article claiming that the Mini Ice Age is already here (pdf).

The new Mini Ice Age is upon us!

“MIA fingerprint now overwhelming” – astrophysicist

“March 10th 1947** was the day of the thaw ending the late snowy cold winter of 1947 in Britain & Europe and there was a giant sunspot group at the centre of the solar disc. This year, three magnetic (22yr) solar cycles later, solar activity has been generally very low and this day marked deep cold” – heralding more snow, on 12th , when snow-blizzards hit S/E England (Pic Folkstone) as WeatherAction forecasted in detail 25 days ahead (see map). “This is further evidence of the inevitable plunge – from now – into the new Mini-Ice Age we warned of some years ago”, said Piers Corbyn, astrophysicist of, March 10th. “The CO2 story is over. It has been pointing the world in the wrong direction for too long. The serious implications of the developing MIA to agriculture and the world economy through the next 25 to 35 years must be addressed.”

(** Piers’ birthday!)

● The CO2 story is over

● World cooling is now ‘locked-in’

● Average solar activity way down

● Jet stream often way south

●Jet Stream develops wild waves giving very extreme weather events – hail, thunder, floods etc

Harshest Russian winter in 70 years – must be global warming

December 20, 2012

Down to -50C: Russians freeze to death

Russia is enduring its harshest winter in over 70 years, with temperatures plunging as low as -50 degrees Celsius. Dozens of people have already died, and almost 150 have been hospitalized.

The country has not witnessed such a long cold spell since 1938, meteorologists said, with temperatures 10 to 15 degrees lower than the seasonal norm all over Russia.

Across the country, 45 people have died due to the cold, and 266 have been taken to hospitals. In total, 542 people were injured due to the freezing temperatures, RIA Novosti reported.

The Moscow region saw temperatures of -17 to -18 degrees Celsius on Wednesday, and the record cold temperatures are expected to linger for at least three more days. Thermometers in Siberia touched -50 degrees Celsius, which is also abnormal for December.

The cold spell, along with snowfalls, has disrupted flights all over the country, and led to huge traffic jams. In the southern city of Rostov-on-Don some highways were closed due to snowfalls over the past two days, triggering a traffic collapse. …

Over the weekend, meteorologists predict temperatures will plunge even lower in the Moscow region, hitting -25. The Russian capital is also expected to be swept with snow, RIA Novosti reported.

Tornadoes and forest fires drastically down – It must be global warming

September 27, 2012

The orthodoxy of the Temple of Climate Science have been busy this summer trying to link every “unusual” weather event to global warming. But every time I see a headline that some weather event has been the worst for 30 or 40 or 100 years, it only serves to  illustrate that the same weather events also occurred 30 or 40 or 100 years ago. And when weather events today are similar to events before 1950 then they can only be further indicators that they are not linked to carbon dioxide emissions.

Even the IPCC realises that weather is not climate.


Breaking weather records from a century ago only shows that it was hotter before CO2 emissions began

July 14, 2012

I am off again on an assignment for a few days and blogging will be light.

It’s summer and where I’m going torrential rain or blistering sunshine with temperatures over 45 °C  are quite normal for this time of year. If it is raining the temperature may be down to 25°C. So I’m prepared for a possible variation of some 20 deg C. It’s just weather.

I note the usual summer stories from around the world of heat waves in some places and “coldest” Junes in a 100 years in others. Some farmers are complaining about droughts and others are complaining about floods. Where societies have ignored repairs or have not built up their infrastructure to match the changing concentrations of urban populations – disasters occur. But I also note that when parts of the US declares that they have just had the hottest period for 50 years or 100 years or whatever and that this is “proof” of global warming they conveniently forget that 50 years ago or 100 years ago or whenever, man-made emissions of carbon dioxide were orders of magnitude lower. When weather records from a hundred years ago are broken it only proves that it was hotter/colder/stormier/wetter/drier or whatever long before the modern industrial age and before any significant man man-made carbon dioxide emissions.  Breaking an old record only shows cyclic behaviour – not “runaway” behaviour!

It’s summer and people are on vacation and journalists are looking for stories and the silly season has begun!

Computer models are only models – and subject to common sense

May 25, 2011

Once again the blind belief in computer models has closed down parts of European air space. Observations and measurements are given less weight than computer models which are at best crude approximations of a chaotic system. The unthinking belief in approximations to reality merely because they are generated by computer models denies the sapience in homo sapiens!!


Most flights have resumed across the UK after a day that saw thousands of passengers affected by an ash cloud from the erupting Icelandic volcano. Air traffic control company Nats said harmful concentrations of ash dispersed from UK airspace overnight. But some flights within the UK and a number to Germany will be cancelled.

As one blogger puts it:

Airline managers are complaining that last year, officials did not do enough to check the actual conditions in the air, instead relying too heavily on computer models showing where the ash was supposed to be. Yet, despite the experience, the International Air Transport Association (IATA) is saying that it is “astonishing and unacceptable” that a British aircraft that is supposed to check actual conditions has been unable to fly.

The disruption arises in part from “volatile winds” which are said to be carrying clouds of volcanic ash down from Iceland over the northern British Isles. But those same winds which caused the rough weather yesterday must also have dispersed the ash.

Without real data, however, forecasters are unable to provide accurate information on ash density and particle size, relying instead on weather patterns and computer modelling to give a rough approximation of conditions. And, with no clear guidance as to closure rules, the only significant difference between this year and last is that the weather conditions are more changeable, allowing more favourable estimates of ash dispersion to be made.

Climate Realists: We know that the Met Office doesn’t bother much with evidence, witness Prof John Mitchell’s unguarded remarks at the Downing College Conference:

People underestimate the power of models. Observational evidence is not very useful,… Our approach is not entirely empirical.
