First, how much warmer has the world become since a) 1880 and b) the beginning of 1997?And what has this got to do with your ever-increasing energy bill?This means that the ‘plateau’ or ‘pause’ 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.‘It is becoming increasingly apparent that our attribution of warming since 1980 and future projections of climate change needs to consider natural internal variability as a factor of fundamental importance.’Professor Phil Jones, director of the Climate Research Unit at the University of East Anglia, who found himself at the centre of the ‘Climategate’ scandal over leaked emails three years ago, would not normally be expected to agree with her. The data does suggest a plateau, he admitted, and without a major El Nino event – the sudden, dramatic warming of the southern Pacific which takes place unpredictably and always has a huge effect on global weather – ‘it could go on for a while’.Like Prof Curry, Prof Jones also admitted that the climate models were imperfect: ‘We don’t fully understand how to input things like changes in the oceans, and because we don’t fully understand it you could say that natural variability is now working to suppress the warming.‘Climate models are very complex, but they are imperfect and incomplete.
Professor Judith Curry, right, from Georgia Tech university in America, disagreed, saying the computer models used to predict future warming were ‘deeply flawed’Some scientists have claimed that this rate of warming is set to increase hugely without drastic cuts to carbon-dioxide emissions, predicting a catastrophic increase of up to a further five degrees Celsius by the end of the century.
The most depressing feature of this debate is that anyone who questions the alarmist, doomsday scenario will automatically be labelled a climate change ‘denier’, and accused of jeopardising the future of humanity. Yes: global warming is real, and some of it at least has been caused by the CO2 emitted by fossil fuels.
But the evidence is beginning to suggest that it may be happening much slower than the catastrophists have claimed – a conclusion with enormous policy implications.
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 any coverage in the media, which usually reports climate issues assiduously, since the figures were quietly release online with no accompanying press release – unlike six months ago when they showed a slight warming trend.
