| Global warming has STALLED since 1998: Met Office admits Earth's temperature is rising slower than first thought
- Earlier forecasts predicted a much steeper rise in global temperatures
- But latest figures from Met Office show slower rise than previously warned
- Figures raise questions about the true danger posed by greenhouse gasses
By Nick McdermottPUBLISHED: 18:26, 8 January 2013 | UPDATED: 22:55, 8 January 2013 The Met Office has admitted that global warming has stalled.Officials say that by 2017, temperatures will not have risen significantly for nearly 20 years.They concede that previous forecasts were inaccurate – and have come under fire for attempting to ‘bury bad news’ by publishing the revised data on Christmas Eve. Rise: The earlier Met Office predictions show a much sharper rise in projected global temperatures through to 2016... Fall: But the new computer model predicts temperatures will stay relatively flat Now a press release, published yesterday, has confirmed that over the next five years temperatures will be 0.43 degrees above the 1971-2000 average, instead of the previously forecast 0.54 degrees – a 20 per cent reduction.This rise would be only slightly higher than the 0.4-degree rise recorded in 1998, an increase which is itself attributed by forecasters to an exceptional weather phenomenon.With all but 0.03 degrees of the increase having occurred by 1998, the revision means that no further significant increases to the planet’s temperature are expected over the next few years.The figures have been seized on by sceptics of man-made climate change, who claim that global warming has flatlined despite a large rise in greenhouse emissions in recent decades.Dr David Whitehouse, science adviser to the Global Warming Policy Foundation, said: ‘That the global temperature standstill could continue to at least 2017 would mean a 20-year period of no statistically significant change in global temperatures. ‘Such a period of no increase will pose fundamental problems for climate models. If the latest Met Office prediction is correct, then it will prove to be a lesson in humility.’ Crack: Pieces of ice breaking away from a glacier in Patagonia, southern Argentina. Phenomena like this is believed by many to be caused by global warming However, Dr Richard Allan of the University of Reading said: ‘Global warming is not “at a standstill” but does seem to have slowed down since 2000, in comparison to the rapid warming of the world since the 1970s. ‘In fact, consistent with rising greenhouse gases, heat is continuing to build up beneath the ocean surface.’ He was backed by Bob Ward of the London School of Economics, who said it would be wrong to interpret that warming had stopped.However, he also condemned the Met Office for releasing data without an explanation of its full meaning.‘It’s true to say this isn’t the Met Office’s finest hour,’ he said.‘The sceptics have simply exploited that fact. I think on this particular occasion the Met Office has fallen short of the standards one would expect of them.’ Labour MP Graham Stringer said the Met Office’s short-term forecasts had improved, but their climate change analysis was ‘poor’.He said: ‘By putting out the information on Christmas Eve they were just burying bad news – that they have got their climate change forecast wrong. ‘For a science-based organisation, they should be more up front, both about their successes and failures.’ The Met Office said the updated five-year predictions were a result of a new modelling system, which takes into account changes in ocean surface temperatures, and was released as soon as practically possible.
