Global warming – science versus political correctness

August 3, 2010

When a scientific question diverges from a treatment of evidence, facts or theories it is often based on beliefs (and a belief by definition comes into play only when facts are lacking). Hypotheses and theories necessarily must rely – to some extent – on belief.

As soon a question regarding facts becomes instead a question regarding beliefs it leads to a political label (right wing, left wing, capitalist, communist, liberal, fascist). A political label generally assumes an adherence to a particular set of beliefs on many diverse topics. A scientific discussion then becomes a political argument. Positions on any topic under the umbrella of the political label – whether or not relevant to the topic under discussion – are then used to “discredit” or “support” a particular belief.

But I note that the “tools” used in political argument are the same whichever side of the political divide one is. These “tools” are used to reinforce the views of those already in agreement or to “convert” those on the fence.  They are only rarely used to “convert” those on the other side of the divide. These tools are for the manipulation of belief and have nothing whatever to do with science or the scientific method. The “tools” commonly used are

  • Alarmism (or the pseudo-science precautionary principle which permits common-sense to be ignored)
  • Claiming to be the “majority” view (and this is resorted to because a “majority” in a democracy is ascribed the “right” to summarily over-rule and oppress a minority)
  • Guilt, wrongness, injustice or immorality  – all by association
  • Ridicule
  • Distortion, misrepresentation and even fraud
  • Inquistions against heretics and witch hunts

The entire AGW argument – for it  has degenerated into a political argument and is no longer a scientific discussion (if it ever was one) – is permeated by the use of such tools. The sound and fury mask the underlying question which remains:

What is the magnitude and significance of man-made effects on the global climate?

My position is that I don’t know.

I believe that it is not of any great significance – but not that it is absent. I believe that whatever effect man has pales into insignificance compared to what the sun does primarily through the oceans and – only then – through and to the atmosphere.

There are those who believe – note “believe” – that posing the question is itself a matter of belief and denies the obvious. For posing the question I have been given various political labels. But the simple fact is that the answer is not obvious and not a settled science for me.

It is entirely a political matter – and perfectly valid as a political matter but it is not a matter of science – when the belief in something so dreadful in the future – but which cannot be proven – is used as a vehicle for satisfying greed (carbon trading, so-called environmental subsidies or research funding) or a political agenda.

There is nothing wrong with having a political agenda. But it cannot be labelled science.

NonScience — not even Pseudo-Science

July 31, 2010

No doubt it is the quest for funding for what are “fashionable” projects which leads to this kind of rubbish. This is not even worthy of being called pseudo science – this is just nonscience (pun intended).

We find that an increase in a state’s unemployment rate decreases Google searches for “global warming” and increases searches for “unemployment,” and that the effect differs according to a state’s political ideology.

This is is what passes for science for University of California economists Matthew Kahn and Matthew Kotchen in their peer-reviewed paper (abstract here)Environmental Concern and the Business Cycle: The Chilling Effect of Recession”.

Apparently this is funded by the National Bureau of Economic Research. Clearly they have surplus funds to disseminate, or was it the trigger words “Environmental Concern” which loosened the purse strings.

Does it really take two University economists to come to the conclusion that

Finally, in California, we find that an increase in a county’s unemployment rate is associated with a significant decrease in county residents choosing the environment as the most important policy issue.

One wonders who the peers who reviewed this article and recommended publication could be — and are they getting any funding from the NBER?

Global Warming: The wagons are circling

Met Office report: global warming evidence is ‘unmistakable’

A new climate change report from the Met Office and its US equivalent has provided the “greatest evidence we have ever had” that the world is warming.

They protest too much.

Since it is the Met Office “this is powerful evidence – perhaps definitive – that the hysteria is overdone”.

The Keepers of Memory

July 28, 2010

Yesterday I met someone after 35 years.

The memories that were triggered were sharp and clear but we each remembered different episodes with differing degrees of clarity. Many memories that surged to the surface were matters that I had not consciously thought of during the 35 year interval.

Why then are some memories stored in the brain with – apparently – no deterioration and a mass or surrounding detail and others are only vague recollections or even non-existent?

Perhaps the answer lies in the protein kinase PKMzeta. In The Beautiful Brain PodcastTodd Sacktor, Professor of Physiology and Pharmacology at SUNY talks about his research regarding the mechanisms of long-term memory storage—and deletion— in the brain.

Sacktor’s research investigates the activity of a class of proteins which are very active around synapses— the protein kinases –  and they come in several varieties in the brain. They catalyze chemical reactions at the synapse, allowing a neuron to become more or less responsive to the electrical firing of its neighbor by aiding reactions that reshuffle neurotransmitter receptors.

Sacktor has identified one kinase in particular—called PKMzeta—which seems to be directly responsible for the maintenance of memory in the brain. When PKMzeta is found at a synapse, the memory encoded there is OK—it’s being maintained. When PKMzeta stops working at a synapse, the memory floats into the abyss of the brain, disassembled into its consituent cellular parts and extinguished from our recollection. In this edition of the podcast, Sacktor discusses his research and its implications on the way we understand memory storage in the brain.

We are already in the Landscheidt minimum !!

July 27, 2010

A Massive Winter Heading for the Northern Hemisphere?

Geoff Sharp’s recent article suggests that the Landscheidt minimum is already upon us.

The winters of the past two years have been noticeably colder. The northern hemisphere in particular has experienced record cold, record snow and a rebuilding of the Arctic sea ice extent. The southern hemisphere this winter has also seen record low temperatures in South America which is resulting in many hundreds of deaths (human and livestock). There are a number of players involved which can be attributed to this cooling trend and when they come together they are capable of dropping the world’s temperatures by a significant amount.

Perhaps the most important player is the Pacific Decadal Oscillation (PDO) which is a hot and cold ocean temperature cycle in the Pacific of about 30 years. The world’s temperature trend very closely matches this cycle which has the potential to override solar activity of the day. The last major PDO cooling event was between 1946 and 1976 which experienced the highest solar cycle on record (SC19) followed by a low cycle (SC20). The deepest cold of this era was recorded when both the PDO and low solar activity teamed up, which is right where we are again today with perhaps a greater influence from the solar side with my predicted imminent grand minimum.

Aside from other ocean oscillations the ENSO pattern has a large short term effect on our climate/weather system. We are just coming out of a rather warm El Nino cycle and current observations are showing the possible impact of a very strong La Nina cooling pattern taking shape.

The La Nina phase is now official with the Australian BOM records showing all the major indicators heading into continued La Nina conditions. Of particular interest is the sub surface temperatures in the Pacific showing a large area 4 deg under normal.

Another oscillation called the Antarctic Oscillation (AAO)  is showing its highest readings since records began in 1979, during the strong 1999 and 2008 La Ninas the AAO was also high.

The cooling phase of the PDO is just beginning and should reduce the strength and frequency of future El Ninos and add extra punch and frequency to upcoming La Ninas.

So the stage is set for one of the most interesting natural experiments, nearly all the cool players are in place with the exception of the Atlantic Oscillation still not in its cool phase. I predict the extra boost from my predicted solar grand minimum along with the  current oceanic conditions the next northern winter will experience conditions similar to the Little Ice Age (1250-1850).

Adolfo Giurfa points to this map showing the cooling oceans.

The winter of 2010 / 2011 could remove many uncertainties and provide a fatal blow to global warming alarmism – though doom-day scenarios will never ever die.

The big global ice melt is not happening

July 26, 2010

Global ice quantities are not decreasing. There is no polar meltdown at either pole.

It would seem that temperatures in the Arctic are running lower than average and the ice extent in the Antarctic continues to be higher than normal.

Perhaps the predictions of global cooling for the next 20 – 30 years are getting more probable. Moreover the sun continues to be far less active than predicted.

I cannot help feeling that global climate can only be consequent to the sun and that the primary vehicle for heat transport is the oceans. Within the atmosphere – where the heat content is puny compared to the oceans – the primary constituent of any significance is water in all its forms and the effect they have on solar radiation and the earth’s re-radiation.

The effects of man or CO2 and woefully inadequate climate models remain in the realms of the fly on the chariot wheel saying “Wow! Look at the all the dust I am raising”.

Egyptian impact crater first spotted on Google Earth

The Kamil Crater in Egypt

(Gebel Kamil 22°01’06″N  26°05’16″E)

Analyses suggest this 45-meter-wide crater in southwestern Egypt, first spotted on Google Earth late in 2008, probably was formed in the last 5,000 years.

Although the crater was first noticed in autumn 2008, researchers have since spotted the blemish on satellite images taken as far back as 1972, says Luigi Folco, a cosmochemist at the University of Siena in Italy. He and his colleagues report their find online July 22 in Science.

During expeditions to the site early in 2009 and again this year, scientists found more than 5,000 iron meteorites that together weigh more than 1.7 tons. The team estimates that the original lump of iron weighed between 5 and 10 metric tons when it slammed into the ground at a speed of around 3.5 kilometers per second, with most of the material vaporizing during the collision. Analyses of soil samples from the site and of sand fused into glass by the impact’s intense heat and pressure may help the team estimate when the event occurred. Preliminary analyses suggest that it happened sometime during the last 10,000 years, probably no more than 5,000 years ago, Folco says.

Of marmosets and dragon flies…….

July 22, 2010

The silly season continues. Mankind is apparently seriously threatened by future plagues of dragon flies which could fly in on the wings of climate change. If the plague doesn’t get us then increasing warming could lead to a tough time from mammoth marmosets.

BBC News reports that climate change has returned a long lost dragon fly to Britain.

The dainty damselfly, a smaller relative of dragonflies, was washed away from its single East Anglian pond in the severe coastal floods of 1952/3. Now, a few individuals have been found at a site in north Kent. Conservationists believe the insects were blown on the wind from France or Belgium where they have become more common, probably due to climate change.

The Telegraph is concerned with weightier matters.

Scientists claim longer summers have led to marmots – which are ground-dwelling ‘squirrels’ – waking up earlier from hibernation, giving them more time to reproduce and gain weight before the next hibernation period. The results showed that since then, the average mass of adult marmots had increased by 11 per cent or 400 grams. The population had also grown by a quarter over a 33 year period. The lead researcher in the study, Dr Arpat Ozgul of Imperial College London, said the population increase could be down to a “short-term response” to longer summers. But he explained further study was needed to shed light on how animals will be affected by climate change in the future.

Back again

July 19, 2010
  1. Watched the World Cup final at a bar in Bilbao. Spain were worthy winners but watch out for Germany in the next 2 Cups. Thank goodness it did not go to penalties. The Dutch approach was a little disturbing. The celebrations in Bilbao were not as exuberant as shown on TV in Madrid. Not too many Spanish flags to be seen.
  2. Paul (Pablo) the psychic octopus can retire with flying colours. He should be granted free Spanish mussels for life. A psychic elephant (named Bua) has been discovered in Sweden!
  3. Southern hemisphere suffering from a cold wave. Even after the record winter in the Northern Hemisphere, alarmists still persist in believing that 2010 will be the hottest year ever!!! But the “homogenisation” of data to show this is less than convincing.
  4. La Nina conditions are establishing themselves and cool temperature for the next few years are likely. However, also coming is major drop of .5 to .7C in the global temps which will take us below normal for a time. In addition, the reason for the drop will easily be linked with the cooling of the Pacific, which will remain in its cool stage for the next 30 years. Once the Atlantic, still warm, goes into its cool stage in 10-15 years, global temps will fall even further, back to where they were in the 1970s. Some of the warming alarmists of today were alarmist about a coming ice age in 1976.
  5. The sun is remarkably quiet and undershooting even the low predictions for Solar Cycle 24 for flux and sunspot numbers. Perhaps SC24 will even undershoot SC5. Landscheidt minimum probability is increasing.

Volcano Katla on Iceland getting ready to erupt?

July 10, 2010

For the last 1000 years eruptions of Eyjafjallajökull on Iceland have always triggered subsequent Katla eruptions. After the ash clouds in the spring caused by the eruptions under Eyjafjallajökul glacier, the region under Katla is rumbling.

There have been 14 earthquakes under the Mýrdalsjökull glacier in the last 48 hours. reported by the Iceland Meteorological Office.

Katla Volcano usually erupts every century, says Iceland’s President Olafur Grimsson. and the last eruption was in 1918. “The time for Katla to erupt is coming close.”

“I don’t say if, but I say when Katla will erupt,” Grimsson says. “We have been waiting for that eruption for several years.”

“It can create, for a long period, extraordinary damage to modern advanced society.”

Significant ash clouds from a Katla eruption could compound the global cooling which has already started. Perhaps we shall soon have another year without a summer!!
