What is it about the temperature that some of us find so hard to accept?
The year just ended was one of the hottest on record. In NSW it was the absolute hottest, in Victoria the second-hottest, and in Australia the third hottest.
The measure is compiled by the Bureau of Meteorology. It dates back to 1910. A separate global reading prepared by the World Meteorological Organisation has 2014 the hottest year since international records began in 1880. Not a single year since 1985 has been below average and every one of the ten hottest years has been since 1998.
That it's getting hotter is what economists call an empirical question - a matter of fact not worth arguing about, although it is certainly worth arguing about the reasons for the increase and what we might do about it.
But that's not the way many Australians see it. I posted the Bureau of Meteorology's findings on Twitter on Tuesday and was told: "Not really". Apparently, "climate-wise we are in pretty good shape."
If the Bureau had been displaying measures of the temperature on a specific day or a cricket commentator had been displaying the cricket score, there would be no quibbling. The discussion would centre about the reasons for the result and its implications.
But when it comes to the slowly rising temperature some of us won't even accept the readings. And that says something about us, or at least about those of us who won't accept what's in front of our faces...
I am not prepared to believe that these people are anti-science. Some of them are engineers, some mining company company executives. Like all of us, they depend on science in their everyday lives.
Nor am I prepared to believe they've led sheltered lives, although it's a popular theory. In the United States a survey of six months worth of coverage on Rupert Murdoch's Fox News Channel found that 37 of its 40 mentions of climate change were misleading.
The misleading coverage included "broad dismissals of human-caused climate change, disparaging comments about individual scientists, rejections of climate science as a body of knowledge, and cherry picking of data".
Fox News called global warming a "fraud", a "hoax" and "pseudo science".
Rupert Murdoch's Wall Street Journal fared little better. 39 of its 48 references were misleading.
In Australia it's not as bad. Rupert Murdoch's The Australian gives more space to climate change than any other newspaper. Its articles are 47 per cent negative, 44 per cent neutral and 9 per cent positive according to the Australian Centre for Independent Journalism.
It's impossible to read The Australian's articles without feeling at least a bit curious about climate change.
Another theory is that it's to do with psychology. Some people are more threatened by bad news than others, making them less able to accept that it's real.
And now a more sophisticated theory suggests that it's not about the facts at all. It's really a debate about the implications, disguised as a debate about the facts. Troy Campbell and Aaron Kay, a researcher and associate professor in neuroscience at Duke University in North Carolina find that belief in temperature forecasts is correlated with beliefs about government regulation and what those forecasts would mean for government regulation.
They assembled a panel of at least 40 Republicans and 40 Democrats and asked each whether they believed the consensus forecast about temperature increases. Half were told that climate change could be fought in a market friendly way, the other half that it would need heavy handed regulation. Of the Republicans, the proportion who accepted the temperature forecast was 55 per cent when they were told climate change could be addressed by the free market and only 22 per cent when they were told it would need regulation.
(Democrats were around 70 per cent likely believe the temperature forecast and weren't much swayed by how climate change would be fought.)
The finding is important. It means that that the first step in getting people to at least agree that it's getting hotter is to stop talking about how to prevent it. Muddying the two, as we do all the time, gets people's backs up.
It is getting hotter. Seven of Australia's ten hottest years on record have been since the Sydney Olympics. Last year was 0.91C hotter than the long-term average. Last year's maximums were 1.16C hotter than long-term average maximums. Warming is a fact. The Bureau of Meteorology accepts it, the government accepts it and it shouldn't be beyond our abilities to accept it.
Then we can talk about what to do.In The Age and Sydney Morning Herald
