TV Sets and Global Warming – a Ground-breaking Study

Climate scientists have developed new models which plot natural oceanic temperature cycles, solar activity, and cathode-ray-tube (CRT) television household penetration against average global temperatures over time.  They show a surprising an unexpected result.  The recent unprecedented change in climate appears to be closely related to the number of cathode ray television sets in use.

At the beginning of the second world war, there were only about 8000 sets in use.  By 1949, there were over 3,602,872 in the US alone, and by 1959 accumulated sales in the US totalled more than 67 million.  Sales continued through the 70s and 80s at over 10 million sets per year.  As the global economy flourished, the trend was replicated all over the developing world.  The studies showed that the globe warmed more and more rapidly, matching the rising numbers of TV sets, until around the turn of the millennium, when it paused for ten years, and now appears to be in decline.

Interestingly, the models hind-cast the temperature variations since 1950 with astonishing accuracy. And critically, when the CRT penetration is removed from the models, we cannot explain those temperature variations.  There is no other acceptable conclusion, no other factor that can achieve the match with temperature variations.

Ah, I hear you object, China and India, the new Asian super-economies, are booming.  The number of TV sets sold is sky-rocketing again.  If Global Warming has ceased, how could it possibly be related to TV sets?  Right now, the number of sets in use in the world is 1416338245.

Pay attention!  TV technology has undergone a sea change.  The cathode-ray tube is out.  In the twenty-first century, flat-screen TFT and LED screens have taken over.  These do not emit the same radiation as the older, earth-warming monsters that sat in the corner of the room and heated our planet.  And as the old CRT screens sputter, distort and die, they are being replaced by the new, green, tree-hugging, polar-bear-loving flatties.  We are saved!

Earlier climate models achieved a reasonable match using global CO2 atmospheric variations, enough to give cause to speculate that the reason for the rise might be CO2.  But only to speculate.  CO2 concentrations are still rising at an increasing rate, but the global temperature since 2000, initially flat, is now declining.

And that, dear readers, should be the end of the argument.  I defy you to show me that this little analysis is any less robust or scientific than all of the scientific reports used by the IPCC, Al Gore, the EU or Skeptical Science.  The data behind my reasoning shows a closer match to world temperature fluctuations than any of the computer models used by NASA, GISS or UEA.

Trust the science on this.  Using our model, we can predict with 98.73% certainty that the temperature will decline for the next thirty years to at least the same level as it was in 1970.  More likely it will be even lower, as by 2040 there will be very few CRTs still in use.

What’s that?  You want to examine my data?  You have a confounded cheek.  It’s commercially sensitive and the TV companies have placed it under an embargo.

And I didn’t archive it, and seem to have lost it.

Potsdam Institute – Professional Advocates

The Potsdam Institute for Climate Impact Research, a group composed of natural and social science researchers, announced a study that “shows” that a solar minimum will not slow global warming.  The study is an attempt at a pre-emptive strike.  The sun goes into a cooler period and bingo – they rush to add to the endless repetitions of predictions of doom.  It’s what they do, and why they exist – to advocate for global warming.

The entire study depends on the assumption that the IPCC climate models are comprehensive and correct in their predictions of twenty-first century climate change.  These models include only the possible causes they know about and are capable of modelling, with all of their weightings of climate forcing tuned to enable reasonable hind-casting, applied to a warming world.  When the models approximately predict the global temperature (they are very approximate, and then only while the earth is warming) the climate change scientists conclude that they have proved their estimate of the climate forcing due to man-made CO2, and that their forecasts of temperature rises to come in the twenty-first century must therefore be correct.  They call this modelling technique “optimal detection”.  That is the technique that Ptolemy used in his geocentric model of the universe, which made very accurate predictions of the motions of the moon, planets and stars.  It took more than a thousand years for later scientists to discover the truth,  That is understandable – the relative predictive accuracy of Ptolemy’s model left little reason to suppose that it might be wrong.  So until Copernicus, Galileo and Kepler, astronomers fully accepted the geocentric model.

Similarly, the Potsdam people take AGW and the IPCC-sponsored models as fact.  The very notion that the earth cools and warms in cycles, and that in inter-glacial periods like the present, there are mini-cycles of warm periods between little ice-ages, is dismissed as unscientific wishful thinking.  It is nothing of the kind.  It’s simple observation.  And within the last two thousand years, we have written history to draw upon.  Written history that documents the Roman Warming and the Medieval Warm Period.  The IPCC claim that the recent warming is unprecedented is false.  So are the models.

There has been a fifteen-year hiatus in the warming, against the model predictions.  Even Phil Jones of the CRU agrees that there has been no statistically significant warming since 1995.  And in spite of the present warmth, all indications are that the PDO is now turning negative, and that in five-to-ten years the AMO will also turn negative.  The earth is in for 20 – 30 years of cooling, while CO2 continues to rise, fed by the economic growth in China and India.  The IPCC models did not predict the flat temperature since 1995, and they do not predict the forthcoming cooling.

Greenhouse gases did not cause the twentieth-century warming, or the earlier MWP and still earlier Roman warming.  When cooling sets in, it will not be because greenhouse gases are reduced, or because we are saved by a quiescent sun.  It will be a result of the natural cycles.

Are Humans the Climate Weapons of Mass Destruction?

The UK Met has led a new study into Global Warming, a review led by Peter Stott of the Met Office Hadley Centre in Exeter.  The review was conducted by six IPCC scientists.  Their arguments and conclusions remind me of a desperate-looking Colin Powell on TV, showing pictures of suspicious-looking Iraqi buildings and claiming that they were strong evidence that Saddam Hussein was concealing Weapons of Mass Destruction.  This is the NZ Herald report of the study’s conclusion:

“The researchers found that no other possible natural phenomenon, such as volcanic eruptions or variations in the activity of the sun, could explain the significant warming of the planet over the past half century as recorded on every continent including Antarctica.”  It goes on:  “It is only when the warming effect of emitting millions of tonnes of carbon dioxide into the atmosphere from human activity is considered that it is possible to explain why global average temperatures have risen so significantly since the middle of the 20th century.”

How did they arrive at this conclusion?  Well, they matched computer models of possible causes of climate change, both human-led and otherwise, to measured changes in factors such as air and sea temperature, Arctic sea ice cover and global rainfall patterns.  They call the technique “optimal detection”, and claim that it showed clear fingerprints of human-induced global warming.  Richard Lindzen has this to say about their application of “optimal detection”:

“they take models that can not reasonably simulate known patterns (such as ENSO, the Pacific Decadal Oscillation, the Atlantic Multidecadal Oscillation), claim that such models accurately depict natural internal climate variability, and use the fact that the models could not replicate the warming episodes… to argue that forcing was necessary and that the forcing must have been due to man”.

Well put.  As Lindzen also points out, their argument constitutes a rejection of scientific logic that makes arguments for Intelligent Design seem rigorous by comparison.  It boils down to argument from ignorance.  They have created models that include only the possible causes they know about and are capable of modelling, with all of their weightings tuned to enable reasonable hind-casting, applied it to a warming world, and shouted “Eureka!” when it sort-of matched expectations (nothing is said about the fifteen-year hiatus in warming from 1995).

To return to Dr Peter Stott, in his review: “”What we see here are observations consistent with a warming world. This wealth of evidence we have now shows there is an increasingly remote possibility of climate change being dominated by natural factors rather than human factors.”

Bunkum.  Stott’s “wealth of evidence” has no more significance than the Iraqi buildings.  There were no Weapons of Mass Destruction in Iraq.  And the endless list of the consequences of Global Warming does not show that we humans are causing it, or that it is catastrophic.  There is no need to go to war.
