'Climate change' coverup of cooling

Sunday Telegraph:

A notable story of recent months should have been the evidence pouring in from all sides to cast doubts on the idea that the world is inexorably heating up. The proponents of man-made global warming have become so rattled by how the forecasts of their computer models are being contradicted by the data that some are rushing to modify the thesis.

So a German study, published by Nature last week, claimed that, while the world is definitely warming, it may cool down until 2015 "while natural variations in climate cancel out the increases caused by man-made greenhouse gas emissions".

A little vignette of the media's one-sided view was given by recent events on Snowdon, the highest mountain in southern Britain. Each year between 2003 and 2007, the retreat of its winter snow cover inspired reports citing this as evidence of global warming.

In 2004 scientists from the University of Bangor made headlines with the prediction that Snowdon might lose its snowcap altogether by 2020. In 2007 a Welsh MP, Lembit Opik, was saying "it is shocking to think that in just 14 years snow on this mountain could be nothing but a distant memory".

Last November, viewing photographs of a snowless Snowdon at an exhibition in Cardiff, the Welsh environment minister, Jane Davidson, said "we must act now to reduce the greenhouse gases that cause climate change".

Yet virtually no coverage has been given to the abnormally deep spring snow which prevented the completion of a new building on Snowdon's summit for more than a month, and nearly made it miss the deadline for £4.2 million of EU funding. (Brussels eventually extended the deadline to next autumn.)

Two weeks ago, as North America emerged from its coldest and snowiest winter for decades, the US National Climate Data Center, run by the National Oceanic and Atmospheric Administration (NOAA) issued a statement that snow cover in January on the Eurasian land mass had been the most extensive ever recorded, and that in the US March had been only the 63rd warmest since records began in 1895.

On April 24 the World Wildife Fund (WWF), another body keen to keep the warmist flag flying, published a study warning that Arctic sea ice was melting so fast that it may soon reach a "tipping point" where "irreversible change" takes place. This was based on last September's data, showing ice cover having shrunk over six months from 13 million square kilometres to just 3 million.

What the WWF omitted to mention was that by March the ice had recovered to 14 million sq km (see the website Cryosphere Today), and that ice-cover around the Bering Strait and Alaska that month was at its highest level ever recorded. (At the same time Antarctic sea ice-cover was also at its highest-ever level, 30 per cent above normal).

The most dramatic evidence, however, emerged last week with an announcement by Nasa's Jet Propulsion Laboratory that an immense slow-cycling movement of water in the Pacific, known as the Pacific Decadal Oscillation (PDO), had unexpectedly shifted into its cool phase, something which only happens every 30 years or so, ultimately affecting climate all over the globe.

Discussion of this on the invaluable Watts Up With That website, run by the US meteorologist Anthony Watts, shows how the alternations of the PDO between warm and cool coincided with each of the major temperature shifts of the 20th century - warming after 1905, cooling after 1946, warming again after 1977 - and how the new shift to a cool phase could have repercussions for decades to come.

AlGore will not let the facts get in the way of his thesis. That is why he dodges debate on the issue and indeed tries to shut down dissent.

I think if he was finishing his second term right now he would be taking credit for global cooling. Look for that to happen if a Democrat get elected in November.
