An article written by T. Moon, I. Joughin, B. Smith and I. Howat from Science/AAAS journal.

The BBC article Climate tech fixes urged for Arctic methane incorrectly identifies the University of Washington as the source for a prediction of the disappearance of sea ice in the Arctic in the next few years.

Analysis from the University of Washington, in Seattle, using ice thickness data from submarines and satellites, suggests that Septembers could be ice-free within just a few years.”

This is factually incorrect. The graph apparently comes from an unidentified online  blog posting which uses some of our data to conduct its analysis. This analysis extrapolates PIOMAS ice volume data to arrive at a date when sea ice might first disappear. This extrapolation represents the analysis and judgement of the unidentified poster of the graph. The University of Washington was not involved in this analysis. We have informed the BBC and asked for a correction.

Update: The BBC has corrected the news piece to reflect the distinction between the use of PIOMAS data and the extrapolation performed elsewhere.

Europe’s Cryosat mission is now watching the ebb and flow of Arctic sea ice with high precision….Tuesday’s release shows a complete seasonal cycle, from October 2010, when the Arctic Ocean was beginning to freeze up following the summer melt, right through to March 2011, when the sea ice was approaching peak thickness. Cryosat found the volume (area multiplied by thickness) of sea ice in the central Arctic in March 2011 to have been 14,500 cubic kilometres. This figure is very similar to that suggested by PIOMAS (Panarctic Ice Ocean Modeling and Assimilation System), an influential computer model that has been used to estimate Arctic sea ice volume
