Row Over IPCC Report As Nations ‘Try To Hide Global Warming Pause’
Scientists working on a landmark UN report on climate change to be published this week are at loggerheads over their explanation for why the earth’s surface temperature has stopped rising as rapidly as they previously predicted.
The report is still in a draft version and will be finalised over the next five days with heated discussion centring on how to explain the fact that since 1998 the earth’s temperature has barely risen.
It is claimed some governments have even tried to intervene to remove references to the 15 year climate change ‘hiatus’ or ‘pause’.
The report – the fifth report by the IPCC and the first in five years – is hugely influential because its conclusions serve as the scientific basis for UN negotiations on curbing emissions of CO2 and other greenhouse gases. A global climate treaty is supposed to be adopted in 2015.
A leaked copy of an earlier draft of the report, seen by The Telegraph, will insist that the likelihood that global warming exists and that its cause is man-made has risen from 90 per cent certainty to 95 per cent certainty.
The study will also make predictions for rises in the earth’s temperature and sea levels to the end of the century.
One scenario suggests an average temperature rise of as little as 1.8 F by 2100 while at the most alarming end of the scale temperatures may rise by as much as 8.6 F, according to the draft version.
In the worst case scenario, the sea level could rise by as much as 3ft by the end of the century, the final report is expected to say.
The report will also touch upon solutions to global warming, including a hugely controversial and expensive proposal to put giant mirrors in space which can deflect the sun’s rays in order to cool the earth down.
The report, co-authored by 257 scientists, will be finalised this week ahead of its publication in Stockholm on Friday.
But scientists are “struggling” to explain the slowdown in global warming since 1998, it is being claimed.
Documents seen by the Associated Press (AP) show attempts at political interference in the final report, and that “several governments that reviewed the draft objected to how the issue was tackled”.
