United States, Germany, and Belgium ask UN IPCC 2013 climate report to cover up or delete fact that no global warming has happened for 15+ years

September 20, 2013

9/19/13, “World’s top climate scientists told to ‘cover up’ the fact that the Earth’s temperature hasn’t risen for the last 15 years,” UK Daily Mail, Tamara Cohen, Political Correspondent

Scientists working on the most authoritative study on climate change were urged to cover up the fact that the world’s temperature hasn’t risen for the last 15 years, it is claimed.

A leaked copy of a United Nations report, compiled by hundreds of scientists, shows politicians in Belgium, Germany, Hungary and the United States raised concerns about the final draft.

Published next week, it is expected to address the fact that 1998 was the hottest year on record and world temperatures have not yet exceeded it, which scientists have so far struggled to explain.

The report is the result of six years’ work by UN’s Intergovernmental Panel on Climate Change (IPCC), which is seen as the world authority on the extent of climate change and what is causing it – on which governments including Britain’s base their green policies.

Germany called for the references to the slowdown in warming to be deleted, saying looking at a time span of just 10 or 15 years was ‘misleading’ and they should focus on decades or centuries.
Hungary worried the report would provide ammunition for deniers of man-made climate change.Belgium objected to using 1998 as a starting year for statistics, as it was exceptionally warm and makes the graph look flat – and suggested using 1999 or 2000 instead to give a more upward-pointing curve.

The United States delegation even weighed in, urging the authors of the report to explain away the lack of warming using the ‘leading hypothesis’ among scientists that the lower warming is down to more heat being absorbed by the ocean – which has got hotter….
The latest report, which runs to 2,000 pages, will be shown to representatives from all 195 governments next week at a meeting in Stockholm, who can discuss alterations they want to make.
But since it was issued to governments in June, they have raised hundreds of objections about the 20-page summary for policymakers, which sums up the findings of the scientists.

What it says will inform renewable energy policies and how much consumers and businesses will pay for them.

The report is expected to say the rate of warming between 1998 and 2012 was about half of the average rate since 1951and put this down to natural variations such as the El Nino and La Nina ocean cycles and the cooling effects of volcanoes.

A German climate scientist – Stefan Rahmstorf, who reviewed the chapter on sea levels – yesterday admitted it was possible the report’s authors were feeling under pressure to address the slowdown in warming due to the ‘public debate’ around the issue.
The draft report, which is not new research but a synthesis of all the work being done by scientists around the world, is likely to be highly disputed at the three-day meeting.It will make the case that humans are causing global warming with carbon emissions even more strongly upgrading it from ‘very likely’ in 2007 to ‘extremely likely’ it is manmade.But scientists are under pressure to explain why the warming has not exceeded 1998 levels although the decade 2000-2010 was the hottest on record.

Alden Meyer, of the Union of Concerned Scientists based in Washington, said yesterday: ‘I think to not address it would be a problem because then you basically have the denialists saying: ‘Look the IPCC is silent on this issue.’

Jonathan Lynn, a spokesman for the IPCC said yesterday: ‘This is the culmination of four years’ work by hundreds of scientists, where governments get a chance to ensure the summary for policymakers is clear and concise in a dialogue with the scientists who wrote it, and have the opportunity to raise any topics they think should be highlighted.’” via Junk Science

“Scientists working on a landmark U.N. report on climate change are struggling over how to address a wrinkle in the meteorological data that has given ammunition to global-warming skeptics: The heating of Earth’s surface appears to have slowed in the past 15 years even though greenhouse gas emissions keep rising.

For years, skeptics have touted what looks like a slowdown in surface warming since 1998 to cast doubt on the scientific consensus that humans are cooking the planet by burning coal, oil and natural gas.

Scientists and statisticians have dismissed the purported slowdown as a statistical mirage, arguing among other things that it reflects random climate fluctuations and an unusually hot year picked as the starting point for charting temperatures. They also say the data suggests the “missing” heat is simply settling — temporarily — in the ocean.

But as scientists study the issue, the notion of a slowdown has gained more mainstream attention, putting pressure on the authors of the new U.N. report to deal with it.“…

The British Met Office forecast even more recently that the temperature interval could continue at a high level until the end of 2017 – despite the rapidly increasing emissions of greenhouse gases. Then global warming would pause 20 years.”…”The exact reasons of the temperature standstill since 1998, are not yet understood, says climate researcher Doug Smith of the Met Office.“…
