My Spectator cover story on the net benefits of climate change sparked a lot of interest. There was an explosion of fury from all the predictable places. Yet not one of my critics managed to disprove my central assertion, that climate change is probably causing net benefits now and is likely to continue doing so for some decades yet. I’ve written responses to some of the critical articles and reproduce them here. 1. Duncan Geere in the New Statesman. Four paragraphs in his piece in turn begin with 'He's right...' so I am glad that Geere confirms that I am right about all my main points. If you read my article you will find that each of Geere's assertions about the eventual harm of climate change are also in my piece.

Climate change has done more good than harm so far and is likely to continue doing so for most of this century. This is not some barmy, right-wing fantasy; it is the consensus of expert opinion. Yet almost nobody seems to know this. Whenever I make the point in public, I am told by those who are paid to insult anybody who departs from climate alarm that I have got it embarrassingly wrong, don’t know what I am talking about, must be referring to Britain only, rather than the world as a whole, and so forth. At first, I thought this was just their usual bluster. But then I realised that they are genuinely unaware. Good news is no news, which is why the mainstream media largely ignores all studies showing net benefits of climate change.

The government has finally seen through the wind-farm scam – but why did it take them so long? To the nearest whole number, the percentage of the world’s energy that comes from wind turbines today is: zero. Despite the regressive subsidy (pushing pensioners into fuel poverty while improving the wine cellars of grand estates), despite tearing rural communities apart, killing jobs, despoiling views, erecting pylons, felling forests, killing bats and eagles, causing industrial accidents, clogging motorways, polluting lakes in Inner Mongolia with the toxic and radioactive tailings from refining neodymium, a ton of which is in the average turbine — despite all this, the total energy generated each day by wind has yet to reach half a per cent worldwide.

The arguments for wind farms just became obsolete. We’re entering an era when gas will be cheap, plentiful – and green Which would you rather have in the view from your house? A thing about the size of a domestic garage, or eight towers twice the height of Nelson’s column with blades noisily thrumming the air? The energy they can produce over ten years is similar: eight wind turbines of 2.5 megawatts (working at about 25 per cent capacity) roughly equal the output of an average Pennsylvania shale gas well (converted to electricity at 50 per cent efficiency) in its first ten years. Difficult choice? Let’s make it easier. The gas well can be hidden in a hollow, behind a hedge.

The government’s new emissions target will despoil the countryside, rob the poor – and enrich landowners like me ‘Greener food and greener fuel’ is the promise of Ensus, a firm that opened Europe’s largest (£250 million) bio-ethanol plant at Wilton on Teesside last year, and has now shut it down for lack of profitable customers. This is actually the second shut-down at the plant — which takes subsidies and turns them into motor fuel — the first being a three-week refit to try to stop the stench bothering the neighbours. Welcome to the neo-medieval world of Britain’s energy policy.

Has Antarctica been getting warmer? To the frustration of many environmentalists, it’s not an easy question. Manned weather stations have existed there for over 50 years, unmanned stations from 1980 onwards. Coverage is patchy both in space and time, with weather stations clustered in a few spots and records full of gaps from when sensors got buried in snow, breakdowns occurred or stations were closed. From 1982, satellites have measured the temperature over the continent but inaccurately, because of clouds and instrument inconsistencies. So taking Antarctica’s temperature involves considerable mathematical skill and leaves much room for statistical disagreement.

Journalists are wont to moan that the slow death of newspapers will mean a disastrous loss of investigative reporting. The web is all very well, they say, but who will pay for the tenacious sniffing newshounds to flush out the real story? ‘Climategate’ proves the opposite to be true. It was amateur bloggers who scented the exaggerations, distortions and corruptions in the climate establishment; whereas newspaper reporters, even after the scandal broke, played poodle to their sources. It was not Private Eye, or the BBC or the News of the World, but a retired electrical engineer in Northampton, David Holland, whose freedom-of-information requests caused the Climategate scientists to break the law, according to the Information Commissioner.
