A couple of my recent forays into the media have provoked comment below the articles themselves and in emails sent querying particular points. They are worth unpacking because they reflect on the different between the straight communication of science and framing risk.
One was in reference to a recent op-ed in The Age. In it, I said:
If people accept the 0.0038 and 0.02 degree benefits as valid then they also accept the science behind a 5.3 degrees warming for business as usual (As in the emission scenario created by Treasury for the 2008 Garnaut Review). Who wants to live in a world warming by 5 degrees or more? Major food crops could not be grown in many parts of the world, projected sea level rise would be tens of metres, most of the shelled species in the ocean would not survive, ecosystems would be disrupted as the pace of change outstripped their ability to adapt and millions to billions of people would lose environmental security leading to mass migrations never before seen.
That prompted an email from an earth scientist wanting to know what peer-reviewed reference I was using for the projected tens of metres of sea level rise. I sent back this now famous diagram and a note saying that I wasn’t putting it on a timetable. He then replied suggesting that people could be misled into thinking that the date was 2100 (because that was tied to the two temperature measures) and that I was being alarmist. Because it would take thousands of years to be realised. Read the rest of this entry »
For those who didn’t catch it, during the week an op-ed of mine was Climate Policy will Stay a Mystery until Silent Specialists Join the Debate was published in The Age. It was based on an earlier post where I detailed the benefits of Australia’s climate policy and the tricks used by opponents to make it look more ineffective than it is likely to be. In the op-ed I ask where are the barefoot economists who will challenge untrue statements about climate and the economy? Text reproduced below (with small edits for clarity).
Little by little: the benefits of Australian climate policy
By Roger Jones, Victoria University
A catchment threatened by salinity can’t be repaired by one or two landholders. Revegetation designed to lower watertables has its greatest ecological benefit where the plants are, but its net impact on salinity is small and spread over a much larger area. To achieve catchment-wide benefits, many good neighbours need to pay a small amount towards revegetation, with everyone contributing according to their capacity. Landcare – an idea invented in Australia and exported overseas – works exactly on that basis. It is supported by all major political parties, and many Landcare programs are funded by the taxpayer.
For climate, any action to permanently reduce greenhouse gas emissions in one region spreads the benefits across the globe. A global effort requires many good neighbours amongst countries who may not know each other well or trust each other very much. Read the rest of this entry »
I’m sure I did not change her mind, but I hope she saw that not all sceptics are mad, bad and dangerous; that there remains a lively scientific debate about the drivers of climate change; and that scaremongering about global warming is backfiring on the warmists.
He goes on to say that of Lomborg’s cornucopian solution:
Lomborg instead advocates significant global investment in green energy research and development in order to make green energy so cheap that everyone will want it.
Now, that I can support. If there is to be any common ground between sceptics and warmists, this surely must be it. Let’s work to make green energy a realistic, affordable alternative, instead of stupidly trying to make conventional energy so incredibly expensive that we will stop using it.
Welcome to the live blog for I Can Change Your Mind About … Climate on ABC1 from 8:30 pm AEST. From the show’s blurb:
Separated by a generation, and divided by their beliefs, two passionate, intelligent and successful Australians go on a journey of mutual discovery to see if they can change each other’s minds about the most divisive issue in Australia today: climate change.
It’s a pity we don’t have cards for climate change bingo to mark off squares for “It hasn’t warmed since 1998”, “scientists are only in it for the grant money”, “the temperature record cannot be believed” and so on. Likewise, I don’t recommend drinking games. You’ll be on your ear by 9. Read the rest of this entry »
Tonight the ABC is broadcasting the battle between science and belief in the minds of ex Senator Nick Minchin and Australian Yoof Coalition founder Anna Rose. This will be followed up by a Q&A on climate change (yep, another one) with panelists
- Rebecca Huntley – social researcher and writer
- Nick Minchin – Former Liberal Minister
- Anna Rose – founder of the Australian Youth Climate Coalition
- Clive Palmer – mining magnate
- Dr Megan Clark – Chief Executive of the CSIRO
Oh goody – not a climate change scientist amongst them, though there will be a few in the audience.
I’m going to live blog the show here.
Stefan Lewandowsky and colleagues will be doing an expert live blog here: http://myresearchspace.grs.uwa.edu.au/events/icanchange and tweeting under the hashtag #qandascientists
Clive Hamilton at Crikey has already concluded that by framing it as a debate, the ABC has handed a win to the doubters. The picture below showing that the largest poll group on the ABC site is dismissive of climate change shows the site is being gamed. My inside intelligence says the program is pretty interesting.
If you want to have fun in my sandpit, come along and join the fun here online and with the TV on from 8:30 Eastern Australian Standard Time.
