Dutch agency admits mistake in UN climate report

A leading Dutch environmental agency, taking the blame for one of the glaring errors that undermined the credibility of a seminal U.N. report on climate change, said Monday it has discovered more small mistakes and urged the panel to be more careful.

But the review by the Netherlands Environmental Assessment Agency claimed that none of the errors effected the fundamental conclusion by U.N. panel of scientists: that global warming caused by humans already is happening and is threatening the lives and well-being of millions of people.

Mistakes discovered in the 3,000-page report by the Intergovernmental Panel on Climate Change last year fed into an atmosphere of skepticism over the reliability of climate scientists who have been warning for many years that human-induced emissions of greenhouse gases could have catastrophic consequences, including rising sea levels, drought and the extinction of nearly one-third of the Earth's species.

The errors put scientists on the defensive in the months before a major summit on climate change in Copenhagen in December, which met with only limited success on agreeing how to limit carbon emissions and contain the worst effects of global warming.

The underlying IPCC conclusions remain valid, said Maarten Hajer, the Dutch agency's director. The IPCC report is not a house of cards that collapses with one error, but is more like a puzzle with many pieces that need to fit together. "So the errors do not affect the whole construction," he said at a news conference.

But he said the boiled-down version of the full IPCC report, a synthesis meant as a guideline for policymakers, included conclusions drawn from "expert judgments" that were not always clearly sourced or transparent.
