“You may be interesting [sic] in this snippet of information about Pat Michaels. Perhaps the University of Wisconsin ought to open up a public comment period to decide whether Pat Michaels, [sic] PhD needs re-assessing?”

– Tom Wigley to ‘Folks’, October 14, 2009.

“I consider this to be an extremely serious matter. [The actions and climate views of] Mr. Bradley … may further damage both my personal and your company’s reputation.”

– Tom Wigley to Kenneth L. Lay (Enron), August 26, 1999.

“We sent [our paper] to Journal of Climate. I sent out about 10 copies–one to Wigley. But I requested that he not be used as a referee ‘because of an inexplicable hostility towards us (and possibly everyone else)’.”

– Gerald North to Robert Bradley (Enron), September 1999.

Michael Mann: “I gave up on Judith Curry a while ago. I don’t know what she thinks she’s doing, but it’s not helping the cause.”

Phil Jones: “I’ve been told that IPCC is above national FOI Acts. One way to cover yourself and all those working in AR5 would be to delete all emails at the end of the process.”

The above emails are representative of the sickly fare of a group of physical scientists who set out to change the world from one of open-ended economic growth to one of economic constraint via international carbon planning. The good news is that the Intergovernmental Panel on Climate Change (IPCC) gatekeepers have once again been exposed by the e-mail release of last week, now known the world over as Climategate 2.0.…

The numbers are in for this year’s summer sea ice extent in the Arctic Ocean. By most measures the ice loss in 2011 came in a close second to the current and still record holder, 2007.

But the failure to set a new record for the least amount of summer Arctic sea ice observed during the satellite era (which begins in 1979) has done little to alter the overall picture of what is going on there. Summer sea ice has been in decline in the Arctic Ocean since, conservatively, the mid-20th century, and it has been picking up steam. And sea ice declines in the Arctic are now pretty clearly discernible in the other seasons as well. (What has been going on around Antarctica is a different story).

But for those who lose sleep at night over the implications of the Arctic sea ice loss to both the local, regional, and global environments, there is a silver lining.…

In a MasterResource article a few months back, I walked everyone through a series of recent scientific findings and described how they cast new light on how the total amount of observed global warming to date could be divvied upon among various causes. I ultimately concluded that the high confidence that the IPCC (and later echoed by the EPA) placed on the statement that “Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations” was misplaced.

This line of reasoning was recently incorporated into statements made by Dr. Patrick Michaels when testifying before the U.S. House of Representatives, Committee on Science and Technology, Subcommittee on Energy and Environment.

During the questions and answers portion of the hearing, one of the other panelists, Dr.…
