Below is what passes for high-powered intellect among Australian Leftists. It is from the blog of the “Lowy Institute for International Policy” which seems to have high pretensions.

No mention of scientific facts is made but “feel” is given prominent mention. Once again it is nothing but ad hominem argument and abuse — which is totally disreputable intellectually. I suspect in fact that our poor old Leftist did not have a clue about how to address the scientific issues involved and thought he could get away with bluff. I think that Frank Lowy, the magnate who founded the Lowy Institute, should be looking for more high-powered employees.

I follow the spurt of superciliousness below with a reply that DOES address the facts. I suppose it is something that they published the reply. The reply is by Alex Avery, son of skeptical author Dennis Avery, mentioned below. Alex is Director of Research at the Center for Global Food Issues, Hudson Institute. He hits the poor old Lowy lamebrains with an actual journal abstract — almost unfair to such simpletons — who probably would not even know which way up to hold an abstract, let alone being able to make anything out of it!

Climate skeptics tilting at windfarms

A few weeks ago I, along with most of my colleagues on the staff and the board of the Lowy Institute, received a complimentary copy of a book called ‘Unstoppable Global Warming – Every 1,500 Years’, by S. Fred Singer and Dennis T. Avery. When I arrived at work there was an enormous pile of these tomes sitting at the Institute’s reception.

The book appears to be a fairly standard example of the `climate change skeptic’ genre. Contrary to the overwhelming scientific consensus captured in the most recent report of the UN Intergovernmental Panel on Climate Change, the authors argue that most global warming is not caused by human activities but by a natural 1500-year climate cycle, and that it is not nearly as dangerous as the Al Gores of this world make out.

I regret to say that this book does not have an authoritative feeling about it, starting with the spelling error in the publisher’s name on the title page. A search of the authors’ names by my colleague Kate Mason took us to the far-right reaches of the Internet, including links to research questioning the link between passive smoking and lung cancer, jeremiads against organic food, and the websites of various American think tanks with the word `freedom’ in their title.

Anyway, people can write whatever nonsense they like; I’m more interested in the fact that someone, somewhere is sending out thousands of copies of this book to anyone they can think of who may be in a position to influence the public debate. The book’s Preface states that: `A public relations campaign of staggering dimensions is being carried forward to convince us that global warming is man-made and a crisis.’ It looks like an expensive campaign is being run against those propositions, too.

I doubt whether it is a very effective campaign, though. The sheer oddness of the whole exercise – both the message and the means of communicating it – leaves the distinct impression that history has passed these people by.


A climate sceptic replies

Your comments about my father’s book are lacking in any substance whatsoever. Spelling errors and perceived lack of ‘authoritative feeling’ aside, where is any mention of the reams of cited peer-reviewed research indicating exactly what the title of the book states: global temperatures today are not historically unusual in comparison to relatively recent times (i.e. most recently the Medieval Warm Period) and the existence of a natural, roughly-1,500-year climate cycle?

By all means, let’s ignore any and all substance and impugn motives instead. How noble. How enlightened. How . . . sad.

Just so you’re not completely in the dark: Dr. Singer’s most recent peer-reviewed scientific paper on climate change was published last month (Dec. 2007) in the International Journal of Climatology published by the Royal Meteorological Society. Does that lack an ‘authoritative feeling’ as well?

As the abstract of the paper states, the authors examined ‘tropospheric temperature trends of 67 runs from 22 “Climate of the 20th Century” model simulations and try to reconcile them with the best available updated observations (in the tropics during the satellite era). Model results and observed temperature trends are in disagreement in most of the tropical troposphere, being separated by more than twice the uncertainty of the model mean. In layers near 5 km, the modeled trend is 100 to 300% higher than observed, and, above 8 km, modeled and observed trends have opposite signs. These conclusions contrast strongly with those of recent publications based on essentially the same data.’

Oh, and here is the latest peer-reviewed scientific paper supporting the argument that current temperatures are not alarming and not unusual:

Loehle, C. 2007. A 2000-year global temperature reconstruction based on non-tree-ring proxies. Energy & Environment 18(7-8): 1049-1058.


Historical data provide a baseline for judging how anomalous recent temperature changes are and for assessing the degree to which organisms are likely to be adversely affected by current or future warming. Climate histories are commonly reconstructed from a variety of sources, including ice cores, tree rings, and sediment. Tree-ring data, being the most abundant for recent centuries, tend to dominate reconstructions. There are reasons to believe that tree ring data may not properly capture long-term climate changes. In this study, eighteen 2000-year-long series were obtained that were not based on tree ring data. Data in each series were smoothed with a 30-year running mean. All data were then converted to anomalies by subtracting the mean of each series from that series. The overall mean series was then computed by simple averaging. The mean time series shows quite coherent structure. The mean series shows the Medieval Warm Period (MWP) and Little Ice Age (LIA) quite clearly, with the MWP being approximately 0.3øC warmer than 20th century values at these eighteen sites.
