Harold Ambler’s book Don’t Sell Your Coat: Surprising Truths About Climate Change contains twelve chapters, each containing details of bad science or bad practice to demonstrate the “dirty pool” the alarmists are prepared to play to keep the scam alive. The saddest part of the story is the fact that the chief culprits are securely based in well funded and prestigious “flagships” of the scientific establishment.
First he provides some perspective on the cycles of climate change. For about three million years the earth has been in a cooler period (an Ice Age), although we are very lucky to be located in a warmer phase, called the Holocene interglacial period which started about 12,000 years ago. The Holocene Optimum, from 8K to 6K years ago was even warmer than the present period. The majority of life forms thrive during these optimums (as indeed will happen if we do get more warming right now). There was a harsher period for about 500 years up to AD 1000 which marked the start of the Medieval Warm Period. The ice melted around Iceland and the Vikings colonised Greenland for 350 years. Then came the Little Ice Age from 1300 to 1850, and then the climate warmed up again.
To keep the current doomsday reporting in perspective he produced a battery of headlines over a period of 100 years to demonstrate that the press has always been beating up stories of impending climate-related disasters, even in this relatively short period, some of these were expected to be caused by cooling, others by warming. Take your pick! Rising CO2 enjoyed a vogue as a harbinger of disaster, but then it turned out that CO2 is not leading temperature trends, but trailing.
Ambler is something of a climate junkie, all his life the Weather Channel was compulsive viewing for him. He notes that the channel has become a huge booster of clarmism, especially by its coverage of extreme weather events and the relantless barrage of image of gigantic pieces of ice falling off glaciers. A few years ago people became concerned about the number of murders the average child sees on TV by age ten, now it would interesting to count the comparable footage on glacial calving, compete with serious if not sinister voiceover.
He has an interesting para on the Maldives. Nils-AxlMorner, a contributing member of the IPCC, measured the sea level on repeated trips to the island and found that in 1970 the sea levels fell 20 cm, almost all at once. Local fishermen confirmed that this was correct, showing him how the contours of the harbours and channels had changed. He recorded no increase in the 39 years since that time.
Has Venice been submerged? asks Ambler. A rhetorical question because he reports that the water comes to the edge of St Marks Square as it has done for centuries. There is concern about the land under the city because Venice may be subsiding but that is a different story.
A recent scare kicked along by Bloomberg News concerns malaria and dengue fever, that are supposed to be on the rise sdue to warming. Paul Reiter, an expert on these matters, felt obliged to resign from the IPCC due to the uncritical treatment of this claim.
In a chapter on the “vanishing ice caps” he explains some of the dynamics of ice movement at the poles, so it is quite possible to have different tendencies at different locations. “But lets stick with the facts. Antarctic sea ice is increasing, and has been during the entire period of satellite measurement. Here’s another fact: the temperature at the South Pole is falling“.
He has a chapter on the gigantic computer models that are used to get a grip on the complexity of climate systems. “Deep Black” in the UK Met Office is one of the largest electricity customers in the nation, consuming 1.2 Metawats, enough power for 100o homes. (Though not homes like the one occupied by Al Gore).
