More trust needed in climate change panel(Read article summary)
A scientific panel requested by the UN delivers a blow to the credibility of the Intergovernmental Panel on Climate Change (IPCC). The advice: remove conflicts of interest and review the data on global warming better.

One of my favorite cartoons shows a man writing a letter while snow falls outside his window. The letter states: âDear weatherman, I just shoveled two feet of âpartly cloudyâ off my driveway.â
Letâs hope the United Nations scientific committee on global warming does not receive such letters in the future. Its forecasts of a toaster Earth this century so far seem on track with record temperatures in recent years. But the committee, known as the Intergovernmental Panel on Climate Change (IPCC), does need to clean up the way it reviews climate data in order to avoid errors and to keep earning the trust of the world.
That was the conclusion of another scientific body, the InterAcademy Council (IAC), in a report Monday. This panel, requested by UN Secretary-General Ban Ki-moon, said the IPCCâs response to recent discoveries of errors in IPCC reports â such as a prediction that the Himalayan glaciers would disappear by 2035 â was âslow and inadequate.â
The climate scientists on the IPCC must avoid conflicts of interest, be more open about scientific uncertainty, and address their critics better, the panel advised. The IAC did not address the use of âgray literature,â sources other than peer-reviewed articles.
The next IPCC reports are due out in 2013-14. Thatâs plenty of time to fix the committeeâs minor credibility problems.
It is a lesson that every TV weatherman (and weatherwoman) has had to learn after a forecast goes bad.
