Shaping Up the IPCC for Unrelenting Scrutiny

September 1, 2010

A review panel commissioned by the world’s science academies has taken a hard look at how the Intergovernmental Panel on Climate Change (IPCC) goes about assessing and reporting on what is known about climate change and how it might affect human society.

The review was spawned by controversy - some legitimate, some manufactured – that raised questions about the IPCC’s credibility and its capacity to publish sound information about climate change and its implications.

An avoidable boner in the latest IPCC assessment about the effect of climate change on Himalayan glaciers crystallized a meme that the IPCC needs to be go on the rack for extensive repairs.

The review panel’s report was filled with strongly worded recommendations for tightening up management, clarifying how uncertainty is communicated, being more cautious about backing up projections with evidence, and improving transparency. It also makes clear, however, that the IPCC "has been successful overall and has served society well."

The review panel said the process improvements would strengthen IPCC for handling the unrelenting scrutiny that has grown along with the political stakes of climate policy and fierce pressure from the climate denial lobby, which spares no effort to sow confusion and spread falsehoods.
