The following is a long post, but on an important issue.
Frontiers is an open source science publisher based in Switzerland. Their aim is to provide an open access, open science platform that empowers researchers in their daily work and where everybody has equal opportunity to seek, share and generate knowledge. They have started up a whole host of “Frontiers in” journals covering a wide range of subjects. They have also been linked with the Nature publishing group who is interested in the open access model Frontiers is developing.
So I jumped at the opportunity to be an associate editor of the newly established area of Interdisciplinary Climate Studies. The Editor in Chief is the Swiss climatologist, Professor Martin Beniston. An associate editor invites a panel of reviewers who review a collection of articles each year. The associate editor establishes their interdisciplinary area with a “challenges” paper to set the ball rolling. Their task is to encourage researchers to submit innovative papers exploring the frontiers of knowledge. Read the rest of this entry »
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?”
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.

The Intergovernmental Panel on Climate Change (IPCC) is the accepted global authority on climate change. It produces reports that are collectively agreed assessments of the scientific literature by leading researchers. The Fifth Assessment Report (AR5) is being delivered over 2013–2014, starting this weekend.
What an IPCC report is
An Intergovernmental Panel on Climate Change (IPCC) report is an assessment that collects and summarises current knowledge in relation to climate change. This is done using literature from peer reviewed and unreviewed (grey) sources.
It is considered the leading review globally of climate change and is produced by a team of hundreds of scientists and specialists from a diverse range of disciplines.
The following statements are typical of the gradualist adaptation narrative:
- Within limits, the impacts of gradual climate change should be manageable.
- Therefore, climate change adaptation can be understood as: (a) adapting to gradual changes in average temperature, sea level and precipitation.
- Gradual climate change allows for a gradual shift in the mix of crops and to alternative farming systems.
So why are Gauss and Newton in the bath and Ed Lorenz in the hot tub?
The NCCARF (National Climate Change Adaptation Research Facility) Climate Adaptation Conference climate adaptation knowledge + partnerships is on from June 25-27 in Sydney. I’m attending to present the results of our recently completed project Valuing Adaptation under Rapid Change. There are many researchers and practitioners of climate adaptation from Australia and overseas here, but there is also a sense of things winding down, because NCCARF finishes up at the end of June with no obvious Commonwealth footprint in climate adaptation beyond that date.
Throw in the recent efforts by some state governments to open up for business and cut green tape, there is a genuine uncertainty about the future of research that aims to improve the three pillars of sustainable development: economy, environment and society, over long time scales. Ahh yes, but I hear you say, research is like policy, it doesn’t only need to be enacted (i.e., published in the peer reviewed literature), it needs to be enabled and implemented. And that’s something that research has not always been able to do. NCCARF has managed to do some of this, but with mixed success.

Today we released research which reduces the range of uncertainty in future global warming. It does not alter the fact we will never be certain about how, exactly, the climate will change.
We always have to make decisions when there are uncertainties about the future: whether to take an umbrella when we go outside, how much to spend on insurance. International action on climate change is just one more decision that has to be made in an environment of uncertainty.
The most recent assessment of climate change made by the Intergovernmental Panel on Climate Change in 2007 looked at what is known with high confidence about climate change, as well as uncertainties. It included projections of future global warming to the end of this century based on simulations from a group of complex climate models.
These models included a range of uncertainties, coming from natural variability of the climate and the representation of important processes in the models. But the models did not consider uncertainty from interactions with the carbon cycle – the way carbon is absorbed and released by oceans, plant life and soil. In order to allow for these uncertainties, the likely range of temperature change was expanded.
