Marohasy: Climate facts to warm to

An interesting interview from the Australian.

Last Monday - on ABC Radio National, of all places - there was a tipping point of a different kind in the debate on climate change. It was a remarkable interview involving the co-host of Counterpoint, Michael Duffy and Jennifer Marohasy, a biologist and senior fellow of Melbourne-based think tank the Institute of Public Affairs. Anyone in public life who takes a position on the greenhouse gas hypothesis will ignore it at their peril.
Read the whole thing and be sure to visit Jennifer Marohasy's blog.

First rate item. Thanks. Clive

Not so first rate.

The claims by Marohasy about global temperature leveling off or dropping are unfounded. A simple email to her source, Roy Spencer at NASA, can clear it up. Which is what I did. Roy states that the data is not from the much vaunted Aqua satellite project as Marohasy claimed, and is not global average but a much smaller sample of 20 degrees either side of the equator.

While you are at Marohasy's blog, have a look around at the rest of it.

Marohasy, the scientist who has misrepresented the information in the interview, appears to have published only a dozen scientific papers or so in areas such as biological control. Her expertise is clearly not climate. She has had a long association with banking, industry and anti-conservation environmental groups that advocate actions like whale hunting. Not the person I would be quoting on climate change.

Finally, the author of the article, Pearson, complains about The Age leaving out some phrases that soften the claims of one of their climate change articles. Pearson has done the exact same thing in this article. See the quoted paragraph from the readily available transcript of the interview from the unashamedly right wing Counterpoint program on the Radio National web site.

"Jennifer Marohasy: It is extraordinary, though I perhaps should pick you up on 'global warming has stopped'. It has stopped for the last ten years, but that's a very short timeframe. If you look over the last 100 years, it's mostly been warming over the last 100 years but there was some cooling from 1940 through to 1975 and now there appears to be some cooling since 1998. But if you look at the longer timeframe, say, since the last glacial maximum, well, that's going back, say, 16,000 years, then there actually has been significant warming, and sea levels of course have risen over 100 metres over this period. So the last eight to ten-year dip may just be a dip, and there may be continued warming into the future, or it could be the end of this interglacial warm period and we could go into another ice age. We don't know what the future holds."

Jennifer, Counterpoint and The Australian should be ashamed.
