Elaine McKewon book-ended my letter to the editors of Fairfax papers The Age and Sydney Morning Herald regarding the publishing of John McLean’s error-ridden piece on the IPCC (the editors, by the way, have not responded) with a terrific take down of McLean in Crikey.
She questioned McLean’s byline on the original article, to whit:
“John McLean is the author of three peer-reviewed papers on climate and an expert reviewer for the latest IPCC report. He is also a climate data analyst and a member of the International Climate Science Coalition.”
asking “But is that accurate? Who is John McLean? What qualifications entitle him to speak as an expert on climate science? What is the ICSC, and which groups, interests and agendas do McLean and the ICSC represent? What exactly does it mean to be an “expert reviewer” of IPCC reports?”
As a result of the statement I made regarding the BoM Annual Climate Statement 2013, I was asked to do a radio interview on ABC drivetime radio in WA, so had a close look at the WA numbers to provide some local background. Average temperature was 0.98°C warmer than the 1961-90 average, the next highest being +0.93°C in 1998. Maximum temperature was also the warmest at +1.11°C compared to +1.00°C in 1994. Minimum temperature was not quite the warmest on record.
But the big shock I got was when I looked at sea surface temperatures (SSTs) for south-west WA. Have a look at this graph (note that 2013 isn’t up there yet due to a delay in processing):
On Friday Jan 3, the Australian Bureau of Meteorology released its Annual climate statement 2013. The headline statements include:
Data collected and analysed by the Bureau of Meteorology show that 2013 was Australia’s warmest year on record while rainfall was slightly below average nationally.
- Summer 2012–13 was the warmest on record nationally, spring was also the warmest on record and winter the third warmest
- Overall, 2013 was Australia’s warmest year on record: annual national mean temperature was +1.20°C above average
- All States and the Northern Territory ranked in the four warmest years on record
- Nationally-averaged rainfall was slightly below average for the year, with 428 mm (1961–1990 average 465 mm)
- Rainfall was mostly below average for the inland east and centre, and above average for the east coast, northern Tasmania and parts of Western Australia
The statement was widely reported – two good summaries by the BoM crew and Lewis and Karoly can be found on The Conversation. One of the biggest talking points was that 2013 was a normal year meteorologically – no El Niño in sight – but the temperature was still a record. Much of the reporting in Australia pointed out the disjuncture between observations and current government policy. The Australian Science Media Centre also had a rapid round-up that included some words from me.
Readers of the Australian press over the holiday period would have seen the spray from Maurice Newman the chairman of the Prime Minister’s Business Advisory Council in The Australian on December 31 where he claimed Australia’s climate policies were being driven by scientific delusion. That was followed by an article by David Karoly in The Age and Sydney Morning Herald on January 1 correcting Newman’s take on the science. Then on January 3, The Age and Sydney Morning Herald printed a response to Karoly and Newman from John McLean. Following is a letter I have sent to the editors of both papers.
I am writing to express my great disappointment at The Age and Sydney Morning Herald’s decision to publish John McLean’s opinion piece Lack of accountability clouds the climate change debate on Friday January 3. After the recent statement by SMH letters editors Julie Lewis and Marc McEvoy that (October 13, 2013) “climate change deniers or skeptics are free to express opinions and political views on our page but not to misrepresent facts”, we in the scientific community were hopeful this would be the case. Alas, it is not.
