The first, on May 21, headed “Climate change threat to Alpine ski resorts” , reported that the entire Alpine “winter sports industry” could soon “grind to a halt for lack of snow”. The second, on December 19, headed “The Alps have best snow conditions in a generation” , reported that this winter’s Alpine snowfalls “look set to beat all records by New Year’s Day”.

Easily one of the most important stories of 2008 has been all the evidence suggesting that this may be looked back on as the year when there was a turning point in the great worldwide panic over man-made global warming. Just when politicians in Europe and America have been adopting the most costly and damaging measures politicians have ever proposed, to combat this supposed menace, the tide has turned in three significant respects.

First, all over the world, temperatures have been dropping in a way wholly unpredicted by all those computer models which have been used as the main drivers of the scare. Last winter, as temperatures plummeted, many parts of the world had snowfalls on a scale not seen for decades. This winter, with the whole of Canada and half the US under snow, looks likely to be even worse. After several years flatlining, global temperatures have dropped sharply enough to cancel out much of their net rise in the 20th century.

Ever shriller and more frantic has become the insistence of the warmists, cheered on by their army of media groupies such as the BBC, that the last 10 years have been the “hottest in history” and that the North Pole would soon be ice-free – as the poles remain defiantly icebound and those polar bears fail to drown. All those hysterical predictions that we are seeing more droughts and hurricanes than ever before have infuriatingly failed to materialise.

Even the more cautious scientific acolytes of the official orthodoxy now admit that, thanks to “natural factors” such as ocean currents, temperatures have failed to rise as predicted (although they plaintively assure us that this cooling effect is merely “masking the underlying warming trend”, and that the temperature rise will resume worse than ever by the middle of the next decade).

Secondly, 2008 was the year when any pretence that there was a “scientific consensus” in favour of man-made global warming collapsed. At long last, as in the Manhattan Declaration last March, hundreds of proper scientists, including many of the world’s most eminent climate experts, have been rallying to pour scorn on that “consensus” which was only a politically engineered artefact, based on ever more blatantly manipulated data and computer models programmed to produce no more than convenient fictions.

Thirdly, as banks collapsed and the global economy plunged into its worst recession for decades, harsh reality at last began to break in on those self-deluding dreams which have for so long possessed almost every politician in the western world. As we saw in this month’s Poznan conference, when 10,000 politicians, officials and “environmentalists” gathered to plan next year’s “son of Kyoto” treaty in Copenhagen, panicking politicians are waking up to the fact that the world can no longer afford all those quixotic schemes for “combating climate change” with which they were so happy to indulge themselves in more comfortable times.

Suddenly it has become rather less appealing that we should divert trillions of dollars, pounds and euros into the fantasy that we could reduce emissions of carbon dioxide by 80 per cent. All those grandiose projects for “emissions trading”, “carbon capture”, building tens of thousands more useless wind turbines, switching vast areas of farmland from producing food to “biofuels”, are being exposed as no more than enormously damaging and futile gestures, costing astronomic sums we no longer possess.

As 2009 dawns, it is time we in Britain faced up to the genuine crisis now fast approaching from the fact that – unless we get on very soon with building enough proper power stations to fill our looming “energy gap” – within a few years our lights will go out and what remains of our economy will judder to a halt. After years of infantile displacement activity, it is high time our politicians – along with those of the EU and President Obama’s US – were brought back with a mighty jolt into contact with the real world.

I must end this year by again paying tribute to my readers for the wonderful generosity with which they came to the aid of two causes. First their donations made it possible for the latest “metric martyr”, the east London market trader Janet Devers, to fight Hackney council’s vindictive decision to prosecute her on 13 criminal charges, ranging from selling in pounds and ounces to selling produce “by the bowl” (to avoid using weights her customers dislike and don’t understand). The embarrassment caused by this historic battle has thrown the forced metrication policy of both our governments, in London and Brussels, into total disarray.

Since Hackney backed out of allowing four criminal charges against Janet to go before a jury next month, all that remains is for her to win her appeal in February against eight convictions which now look quite absurd (including those for selling veg by the bowl, as thousands of other London market traders do every day). The final goal, as Neil Herron of the Metric Martyrs Defence Fund insists, must then be a pardon for the late Steve Thoburn and the four other original “martyrs” who were found guilty in 2002 – after a legal battle also made possible by this column’s readers – of breaking laws so ridiculous that the EU Commission has even denied they existed (but which are still on the statute book).

Readers were equally generous this year in rushing to the aid of Sue Smith, whose son was killed in a Snatch Land Rover in Iraq in 2005. Their contributions made it possible for her to carry on with the High Court action she has brought against the Ministry of Defence, with the sole aim of calling it to account for needlessly risking soldiers’ lives by sending them into battle in hopelessly inappropriate vehicles. Thanks not least to Mrs Smith’s determined fight, the Snatch Land Rover scandal, first reported here in 2006, has at last become a national cause celebre.

May I finally thank all those readers who have written to me in 2008 – so many that, as usual, it has not been possible to answer all their messages. But their support and information has been hugely appreciated. May I wish them and all of you a happy (if globally not too warm) New Year.

The Real Cost of Tackling Climate Change

Thursday, May 15th, 2008

April 28, 2008; Page A19

The usual chorus of environmentalists and editorial writers has chimed in to attack President Bush’s recent speech on climate change. In his address of April 23, he put forth a goal of stopping the growth of U.S. greenhouse gas emissions by the year 2025.

“Way too little and way too late,” runs the refrain, followed by the claim that nothing less than an 80% reduction in emissions by the year 2050 will suffice – what I call the “80 by 50” target. Both Hillary Clinton and Barack Obama have endorsed it. John McCain is not far behind, calling for a 65% reduction.

We all ought to reflect on what an 80% reduction of greenhouse gas emissions by the year 2050 really means. When we do, it becomes clear that the president’s target has one overwhelming virtue: Assuming emissions curbs are even necessary, his goal is at least realistic.

The same cannot be said for the carbon emissions targets espoused by the three presidential candidates and environmentalists. Indeed, these targets would send us back to emissions levels last witnessed when the cotton gin was in daily use.

Begin with the current inventory of carbon dioxide emissions – CO2 being the principal greenhouse gas generated almost entirely by energy use. According to the Department of Energy’s most recent data on greenhouse gas emissions, in 2006 the U.S. emitted 5.8 billion metric tons of carbon dioxide, or just under 20 tons per capita. An 80% reduction in these emissions from 1990 levels means that the U.S. cannot emit more than about one billion metric tons of CO2 in 2050.

Were man-made carbon dioxide emissions in this country ever that low? The answer is probably yes – from historical energy data it is possible to estimate that the U.S. last emitted one billion metric tons around 1910. But in 1910, the U.S. had 92 million people, and per capita income, in current dollars, was about $6,000.

By the year 2050, the Census Bureau projects that our population will be around 420 million. This means per capita emissions will have to fall to about 2.5 tons in order to meet the goal of 80% reduction.

It is likely that U.S. per capita emissions were never that low – even back in colonial days when the only fuel we burned was wood. The only nations in the world today that emit at this low level are all poor developing nations, such as Belize, Mauritius, Jordan, Haiti and Somalia.

If that comparison seems unfair, consider that even the least-CO2 emitting industrialized nations do not come close to the 2050 target. France and Switzerland, compact nations that generate almost all of their electricity from nonfossil fuel sources (nuclear for France, hydro for Switzerland) emit about 6.5 metric tons of CO2 per capita.

The daunting task of reaching one billion metric tons of CO2 emissions by 2050 comes into even greater relief when we look at the American economy, sector-by-sector. The Energy Department breaks down emissions into residential, commercial (office buildings, etc.), industrial, and transportation (planes, trains and automobiles); electricity consumption is apportioned to each.

Consider the residential sector. At the present time, American households emit 1.2 billion tons of CO2 – 20% higher than the entire nation’s emissions must be in 2050. If households are to emit no more than their present share of CO2, emissions will have to be reduced to 204 million tons by 2050. But in 2050, there will be another 40 million residential households in the U.S.

Today, the average residence in the U.S. uses about 10,500 kilowatt hours of electricity and emits 11.4 tons of CO2 per year (much more if you are Al Gore or John Edwards and live in a mansion). To stay within the magic number, average household emissions will have to fall to no more than 1.5 tons per year. In our current electricity infrastructure, this would mean using no more than about 2,500 KwH per year. This is not enough juice to run the average hot water heater.

You can forget refrigerators, microwaves, clothes dryers and flat screen TVs. Even a house tricked out with all the latest high-efficiency EnergyStar appliances and compact fluorescent lights won’t come close. The same daunting energy math applies to the industrial, commercial and transportation sectors as well. The clear implication is that we shall have to replace virtually the entire fossil fuel electricity infrastructure over the next four decades with CO2-free sources – a multitrillion dollar proposition, if it can be done at all.

Natural gas – the preferred coal substitute of the moment – won’t come close. If we replaced every single existing coal plant with a natural gas plant, CO2 emissions from electric power generation alone would still be more than twice the 2050 target. Most environmentalists remain opposed to nuclear power, of course. It is unlikely that renewables – wind, solar, and biomass – can ever make up more than about 20% of our electricity supply.

Suppose, however, that a breakthrough in carbon sequestration, a revival of nuclear power, and a significant improvement in the cost and effectiveness of renewables were to enable us to reduce the carbon footprint of electricity production. That would still leave transportation.

Right now our cars and trucks consume about 180 billion gallons of motor fuel. To meet the 2050 target, we shall have to limit consumption of gasoline to about 31 billion gallons, unless a genuine carbon-neutral liquid fuel can be produced. (Ethanol isn’t it.) To show how unrealistic this is, if the entire nation drove nothing but Toyota Priuses in 2050, we’d still overshoot the transportation emissions target by 40%.

The enthusiasm for an 80% reduction target is often justified on grounds that national policy should set an ambitious goal. However, claims on behalf of alternative energy sources – biofuels, hydrogen, windpower and so forth – either do not match up to the scale of the energy required, or are not cost-competitive in current form.

How on God’s green earth will we make up the difference? Someone should put this question to the candidates. And not let them slide past it with glittering generalities.

Global Cooling

Tuesday, April 22nd, 2008

William Gray is considered the world’s greatest (self-proclaimed) hurricane expert – Gray spoke last year at a national meteorological conference in which he stated that there is no evidence to support the theories that global climate change has resulted in either a greater number of hurricanes or more intense hurricanes.

And according to NewsMax this week:

Hurricane Expert Reconsiders Global Warming Link


Prominent MIT hurricane scientist Kerry Emanuel has publicly reversed his view regarding global warming’s alleged impact on hurricanes.
“The [computer] models are telling us something quite different from what nature seems to be telling us,” said Emanuel, whose views on hurricanes and global warming have been prominently cited by Al Gore and other promoters of climate change fear.
He told the New York Times. “There are various interpretations possible: The big increase in hurricane power over the past 30 years or so may not have much to do with global warming, or the models are simply not faithfully reproducing what nature is doing. Hard to know which to believe yet.”

In 2005, a few weeks before Hurricane Katrina struck New Orleans, Emmanuel asserted in a paper that he had found statistical evidence linking rising hurricane energy and global warming.
 

His conversion is a very important new development in the climate debate, said Marc Morano, a top aide to climate change skeptic Sen. James Inhofe, R-Okla.

“First, 2007 turned out to be the ‘tipping point’ for global warming fears, and 2008 appears to be the year of vindication for skeptics as many prominent scientists reverse their climate views, more and more skeptical scientists speak out, and new data debunks man-made climate fears. “Now another major scientist reconsiders his views on a significant aspect of man-made climate fears.”
