Another Global Warning Hoax Scientist

[Rosa Lichtenstein]

A second scientist has now come out in public and joined Prof Wunsch in denouncing that bogus documentary, and the way his work was misrepresented by Durkin:

Regarding: “The Great Global Warming Swindle”, broadcast in the UK on Channel 4 on March 8, 2007

We have concerns regarding the use of a graph featured in the documentary titled ‘Temp & Solar Activity 400 Years’. Firstly, we have reason to believe that parts of the graph were made up of fabricated data that were presented as genuine. The inclusion of the artificial data is both misleading and pointless. Secondly, although the narrator commentary during the presentation of the graph is consistent with the conclusions of the paper from which the figure originates, it incorrectly rules out a contribution by anthropogenic greenhouse gases to 20th century global warming. These concerns are detailed below.

And this from the New Scientist last week:


Upper oceans are warming after all
28 April 2007

Climate-change naysayers pounced on a report last year suggesting that the upper oceans are cooling, not warming. Now it turns out this conclusion was wrong, the result of faulty measurements.

The Argo project was launched in 2000 to record ocean temperature and salinity all over the world, using a network of 3000 floats containing sensory equipment to gather data through the upper 2000 metres of the ocean. Unfortunately, 300 were mis-recording the water pressure, making the floats appear closer to the surface than they really were. Before Argo, ocean temperature was measured using sensors called XBTs that were thrown into the sea, where they slowly sank. These sensors didn't fall as fast as originally assumed. Water is warmer near the surface, so the XBT temperature readings were too high and some Argo readings too low.

When John Lyman from the US National Oceanic and Atmospheric Administration's Pacific Marine Environmental Laboratory in Seattle, Washington, and his colleagues compared the Argo and XBT measurements, it appeared that the upper oceans had cooled by 0.02 °C between 2003 and 2005 (Geophysical Research Letters, DOI: 10.1029/2006GL027033). In fact the cooling was an artefact, caused by the switch from XBTs to Argo, combined with the faulty floats. Lyman's team has submitted a correction and is recalibrating the data. Calculations are still ongoing, but it now looks like no cooling occurred.

"The upper ocean cooling was always surprising because the change was so sudden," says Josh Willis of the Jet Propulsion Laboratory in Pasadena, California.
