Heat Wave in Europe: The Mystery Unveiled
by Eduardo Ferreyra (September 16th, 2003)
The recent heat in Europe made headlines in the media and was used as an evidence that "global warming" is a fact. Guess what: human activities had nothing to do with it.
After a brief review of recent history and the fundamentals of meterology and climatology, it has been possible to determine that the causes for the recent heat in Europe have its origin in a climatic phenomenum known for many decades as the "Jet Stream", strong winds whirling around the North Pole, having a decisive influence on the Northern Hemisphere and the rest of the world. Let us see in detail what is this thing called the "Jet Stream".
It is a current of very strong winds in the stratosphere whirling around the North Pole, from west to east, and they do it a varying speeds, according to not very well understood reasons. Some years they blow at very high speeds, making the current fairly straight; other years they slow down and start 'snaking' and twisting in their path, making deep entrances to the equator, and far north to the North Pole. Figure 1 (and the next ones) give an idea about how climatologists understand this.
Like a snake chasing its own tail, the westerly winds ondulates around the globe tracing the trajectory of the Jet Stream in the high troposphere. A strong circulation corresponds to a compressed circumpolar vortex; a weak circulation corresponds to a highly irregular and ondulating Jet Stream. Such configurations severly affect the climate in the Northen Hemisphere.

While all this was happening in Europe, the Great Plains in the northern pat of central USA had experienced, sinde January 10th to the january 12th, 1975, one of the worst blizzards in the hsitory of that region. This kind of deep freezing climatic events has been repeating themselves with great regularity in the last years, particularly since the late 80s when Time magazine dedicated its first cover of 1989 to the "warmest year ever recorded", 1988 just two weeks before one the worst blizzard ever recorded came down over the entire country.
The winter of 2003 in the Nortern Hemisphere broke all records in freezing temperatures, and the ice in Finland came 15 days earlier than usual. Summer temperatures in the Southern Hemisphere were mild and cooler than normal. There is nothing strange in this, since this coincides with a diminishing solar activity and sunspots. Astrophysicists predict a new Double Minimum (Gleissberg) for the year 2030, a solar condition that will have a freezing influence on Earth, taking temperatures down to the same as those of the Little Ice Age of 1610 onwards, when the Double Minima Maunder and Spoerer occurred. The decrease in the number of sunspots is slow, but steady, and this will make temperatures go down until they reach the ones during Galileo Galilei times.
This has been seen during the long and cold winter in the Southern Hemisphere, where subzero temperatures were recorded during a period of many consectuvie days, and indicator that the prophesized catastrophic global warming has no signs of revealing itself. A mild and cool 2003 summer, and the late frosts and spring snowfalls in the Andes and Cordoba Sierras were unusual, suggesting that a slight cooling is on its way. Everythings seems to indicate we are heading to a new Little Ice Age and, as we are at the endo of the Holocen climatic period, is quite feasible that the planet will slide slowly towards a new glaciation.
Data in climatic records are curious, to say the least. Let us see. Since 1973 until 1978, climatologists recorded the following: The coldest winter since 1740; the driest since 1743; the mildest since 1834; the biggest drought since 1725; the warmest mont of July (1976) since recordings began about 300 years ago. The extreme conditions continued with an almost inexistent summer in Europe in 1978, followed by an extraordinarily good and dry autumn that broke all marks. In january 1979, Great Britain suffered the worst winter ever recorded - 2003 was not much better.
On January 1981, The Times of London published a headline: HUNDRED DIE WHILE COLD GRIPS THREE CONTINENTS, and informed about the difficulties caused by strong snowfalls in Spain and southwest of France, plus a "more than usual" bad weather in Japan and a state of emergency declared in Florida, after two days of severe frosts provoked serious damage to crops (tomatoes, citrus, and sugar cane). At this point it is worth noting that the "frost lines" (isotherms), the south limit of frosts, annually drawn by the US Weather Service show that they have been gradually moving 150 kilometers to the south for the last 50 years or so - from Jacksonville to Orlando. You cannot grow oranges north of Orlando if you want to have a decent crop.
In those years, China suffered one of the worst climatic calamities since the civil war of the 40s. In the Hubei province, 800 kilometers south of Beijing, the main problem were floods that destroyed schools, hospitals, electric utilities, bridges, roads, and 210,000 homes, causing damages estimated in economic terms in 1 billion dollars, and the lost of 2,5 million tons of grain.
In the Hebei province, around Beijing itself, the problem was drought. In 1980, the rain monthly mean never went over 80% of "normal", and in many cases didn't even reach 30%. The losses in grain summed up to 4,5 million tons, and the level of underground water went so low that the provision of "drinkable" water was compromised. The problems of a suffering population were exacerbated by a terrible winter. China had to resort to help from the Western countries, but the trouble was they had to deal with their own problems, especially when the drought repeated again in the USA for a second year in a row, in 1981.
Nobody will be surprised now to know that the drought was caused by a blocking anticyclone over the western part of the USA. Not one, but three droughts, in the west, in the corn belt, and in the northwest, were the consequences of a complex blocking system that affected the whole of North America. The meteorological science is still unable to explain accurately why all that set of events had to occurr in a particular year, nor can predict the formation of such a blocking system. However, the science can put all those problems in their adequate historical perspective. We don't know exactly when blocking systems will happen, but we can see that the increasing frequency of droughts, heavy rains, and other climatic extrema should make us expect a return to the climatic conditions prevailing during the last millenium.
Climatology has received new contributions comingfrom other scientific fields, especially from astrophysics and astronomy. The most recent researchs in these fields allow now to predict with high accuracy the increase and decrease of solar activity, according to the position of the Sun regarding the baricenter (center of masses of the solar sustem), as the planets orbit around the Sun. It has been proved, beyond nay doubts or specualtions, that the sun's magnetic cycles have a decisive influence over important climatic events as the El Niño/ENSO, the amount of cosmic rays entering Earth's atmosphere (which determines de formation of clouds), and other vital things as the North Atlantic Oscillation. All these powerfull factors, interacting within a very complex system as the atmosphere, makes the rol of CO2 as the main driving force behind the global warming, each day more insignificant and meaningless.
This also leaves on the open the useless futility of general circulation model, inefficient imitations of the Earth's climate usaed by the greenhouse industry in order to promote scare campaigns about the climatic future of the planet, trying to impose restrictive measures to fossil fuel uses with more geopolitical implications than a real intention to stop an irreal warming that has not happened, not it has signs of ever happening.

These estimates are based on computer climate modeling, a branch of science still in its infancy despite recent substantial strides in knowledge. This paper demonstrates why computer modelling can not be trusted at all.
8. A Global Warming Primer: by by Gerald E. Marsh, physicist at Argonne National Laboratory - The purpose of this primer is to help the reader determine whether our understanding of the Earth's climate is adequate to predict the long term effects of carbon dioxide released as a result of the continued burning of fossil fuels. "... Given the uncertainties described above, and the current state of coupled ocean-atmosphere general-circulation models, the predictions of these models cannot and do not form a sound basis for public policy decisions."
