Climate Scientists Pursued By Sceptics Through Courts Of Law And Public Opinion

THE climate science denial industry doesn’t like Penn State University’s Professor Michael Mann very much.

Mann is the scientist behind the famous “hockey stick” graph that first appeared in the journal Nature in 1998.

Mann and two other scientists Professor Raymond Bradley and Professor Malcolm Hughes had reconstructed temperatures in the Northern Hemisphere from the year 1400 to present day using data mainly from tree rings, ice cores and modern temperature readings.

The following year, the same three scientists extended their study to reconstruct 1000 years of temperatures and published this in the journal Geophysical Research Letters.

Each time the team plotted their data on graphs and each time the plots showed what is the now famous “hockey stick” shape with a sharp uptick in temperatures towards the end of the century.

What really got the ire of the climate science denial industry and its cheerleaders was that this second study showed that modern day temperatures were likely hotter than they had been in the so-called Mediaeval Warm Period.

This negated a key argument from sceptics – which they continue with today – that it’s been warmer in the recent past before the industrial revolution caused the westernised world to fall in love with fossil fuels.

Incidentally, it was never a very convincing argument anyway. Even if it was warmer in the past, it doesn’t challenge the multiple lines of evidence which point to burning fossil fuels and deforestation as the main cause of the rapid warming, ocean acidification and sea level rises we see now.

But anyway, enough of the climate science history lesson. Back to Michael Mann.

I Can Engage In A Flawed Debate About Climate Change

APPARENTLY, science writer and academic Ben Goldacre would rather slam his “cock in a door” than engage in a phony debate with climate change deniers.

At least, that’s what he told former Liberal Senator and climate sceptic Nick Minchin and climate change campaigner Anna Rose during the filming for this Thursday evening’s ABC show “I Can Change Your Mind About… Climate”.

The concept of the show is simple. Get a climate sceptic and a climate advocate together and let them take each other around the world to meet people in an attempt to change each other’s mind.

Nick Minchin laid out his own position during an interview with the ABC’s Four Corners program, back in 2009. Basically, it boiled to “lefties” exploiting people’s innate fears about climate change “to achieve their political ends”.

Be warned, Mr Minchin, as secret lefties like British Tory Prime Minister David Cameron and that famous anti-capitalist Richard Branson are also in on the socialist plot.

I should admit I’ve known about the program for many months, as I was approached to act as an advisor in the planning stages. Nothing materialised. I also spoke many months ago to Anna Rose about the show.

In both instances, I said that in my view the show’s format was flawed in that it would put non-peer-reviewed, pseudo science conducted by largely unqualified non-experts alongside decades of genuine peer reviewed scientific research. It might make for engaging telly, but it creates a false sense of balance.

If I were a climate sceptic activist or a fossil fuel lobbyist designing a format for a TV show, this show is what I’d probably come up with.

In an excerpt broadcast on radio national’s The Science Show, Goldacre explains why he thinks the show’s format is questionable and how, as part of the broader treatment of the climate change issue in mainstream media, it is a “gift” for the likes of Minchin.
