Bob Grumbine calmly explains to Tony about the problem in trusting Steve Goddard,
There's a bit of a tempest at WUWT and Steven Goddard's regarding satellite data on sea ice. And there are some anxious comments about FOIA filings to be made regarding data that's been hidden. I have to concede that it takes a bit of a historian to know what's really being said in the IPCC first report regarding sea ice. (see page 224, figure 7.20 for the source of the tempest.) Fortunately, I am such a historian :-) To give away the ending: There's nothing terribly dramatic going on in the sea ice or the history. But I'll take the chance to talk history of sea ice analysis.Go read the whole story. Meanwhile at the place where this all started, the Weasel, Julienne Stroeve and Bob try and clear things up, summarized by Guenther Kirschenbaum
The tempest arises because the figure shown there has sea ice cover in the early 1970s in the Arctic being notably lower than it was through the 1980s. (Curiously, no interest is displayed at either site regarding the Antarctic being far higher in the 1970s than the 1980s.) If the figures were commensurate with the satellite observations such as those used in the Cryosphere Today anomaly figures, it would suggest that the Arctic coverage of the last few years wasn't as remarkable as we've generally thought. (On the other hand, it would also say that the 'record high' Antarctic coverage of recent years was not particularly high at all, a point being neglected at both sites.)
In other news, the Yorkshire Ranter wanted to know how the Montreal Protocols could have been passed.
Perhaps more telling is this NASA web page, which describes the output from the Goddard Space Flight Centre's Chemistry-Climate Model given inputs corresponding to a world that kept using the stuff. It's either utterly terrifying, or enormously inspiring, depending on how you look at it. Rowland, Paul Crutzen, the British Antarctic Survey people who did the fieldwork...they essentially saved the world.Eli had a thought
But what really interests me was how they got the Vienna and Montreal protocols passed. I had the vague impression that something had changed since 1989, that the ex-tobacco industry unscience industry was only cranked up later to bash the climatologists. In fact, I'm wrong. A comment at Realclimate points out that they were indeed targeted by the usual suspects. Rowland was accused of being a KGB agent trying to destroy capitalism
One of the things was that Dupont and ICI management was still full of chemists and that Thatcher herself (although they are reluctant to take credit) was an Oxford chemistry BA. So even though they didn't want to believe the science they had the tools to understand it.
