More experts on the way, experts warn

Out on the sticky fringes of the expert industry is Professor Ian Plimer, a geologist who wrote a successful book proposing that climate change might not be as bad as all that. The most common criticism of it has been that, as an expert on rocks, he should confine himself to writing and talking about rocks. It's a handy argument that allows his critics, a surprising number of whom proudly proclaim they know nothing about science themselves, to avoid engaging with the actual content of the book.

One of the features of the climate debate is indeed a total reliance on experts. The number of people who say ''I don't understand the science'' and then go on to propose or endorse plans that would completely restructure society is amazing. They do this because a lot of experts, aka ''the consensus'', say they should.

A farmer's field of dreams buries climate change war

The battle's unlikely heroes are Mr Linklater and his 400-horsepower, oxygen-sucking, diesel-guzzling, carbon-spewing tractor.

International debate rages over the cost and plausibility of reducing greenhouse gas emissions from coal-fired power stations by pumping carbon underground.

But Mr Linklater is literally ploughing ahead, injecting his tractor's fossil fuel exhaust fumes directly into the ground, where they enhance the biochemical interaction between plants and soil microbes. And it seems his home-grown version of carbon sequestration, introduced in 2007, is getting results, with this year's crop, aided by better rainfall, his best since 2001.
