New evidence, quietly released by the UK Met Office, suggests that there has been no discernible warming since 1997:
The world stopped getting warmer almost 16 years ago, according to new data released last week.
The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures.
This means that the â€˜plateauâ€™ or â€˜pauseâ€™ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years.
The new data, compiled from more than 3,000 measuring points on land and sea, was issuedÂ quietly on the internet, without any media fanfare, and, until today, it has not been reported.
This stands in sharp contrastÂ to the release of the previousÂ figures six months ago, which went only to the end of 2010 â€“ a very warm year.
Ending the data then means it is possible to show a slight warming trend since 1997, but 2011 and the first eight months of 2012 were much cooler, and thus this trend is erased.
I have always suspected this would be the case. and yet it is me and people like me who are called deniers…well the denier label is about to lifted from us and placed firmly onto the warmists.
Here are three not-so trivial questions you probably wonâ€™t find in your next pub quiz. First, how much warmer has the world become since a) 1880 andÂ b) the beginning of 1997? And what has this got to do with your ever-increasing energy bill?
You may find the answers to the first two surprising. Since 1880, when reliable temperature records began to be kept across most of the globe, the world has warmed by about 0.75 degrees Celsius.
From the start of 1997 until August 2012, however, figures released last week show the answer is zero: the trend, derived from the aggregate data collected from more than 3,000 worldwide measuring points, has been flat.
Not that there has been anyÂ coverage in the media, which usually reports climate issues assiduously, since the figures were quietly release online with no accompanying press release â€“ unlike six months ago when they showed a slight warming trend.
The answer to the third question is perhaps the most familiar. Your bills are going up, at least in part, because of the array of â€˜greenâ€™ subsidies being provided to the renewable energy industry, chiefly wind.
They will cost the average household about Â£100 this year. This is set to rise steadily higher â€“ yet itÂ is being imposed for only oneÂ reason: the widespread conviction, which is shared by politicians of all stripes and drilled into children at primary schools, that, without drastic action to reduce carbon-dioxide emissions, global warming is certain soon to accelerate, with truly catastrophic consequences by the end of the century â€“ when temperatures could be up to five degrees higher.
Hence the significance of those first two answers. Global industrialisation over the past 130 years has made relatively little difference.
