Bjorn again: Lomborg’s convenient change of heart

by Bryan Walker September 2, 2010

Bjorn Lomborg is in the news again. He’s changed his tune, says a Guardian headline, announcing the forthcoming publication of a new book edited by him, Smart Solutions to Climate Change: Comparing Costs and Benefits. That was a pretty quick change, I thought, recalling what I heard him say on a panel at the PEN [...]

The InterAcademy Council report on the IPCC — Climate Change Assessments: Review of the Processes and Procedures of the IPCC — released yesterday, calls for “fundamental reforms” to the IPCC’s management structure and review processes.

Report clears IPCC head Pachauri, UK paper apologises

by Bryan Walker August 27, 2010

Back in March I posted on IPCC Chairman Rajendra Pachauri’s stout defence of the IPCC report against the attacks to which it was being subjected by hysterical denialism.  But he has also had to defend himself against accusations in an article by Christopher Booker and Richard North in the Sunday Telegraphin December which claimed that [...]

We call upon the author…

by Gareth June 29, 2010

I must have been asleep last week when the IPCC announced its selection of authors for the Fifth Assessment Report (AR5), due in 2013/14.

IPCC’s Pachauri fights back

by Bryan Walker March 28, 2010

“We have a very apt saying in Hindi, which essentially translates as: ‘When a jackal is threatened, he starts moving toward the city.’ In other words, he becomes more visible. I think some of these guys are speaking out volubly because they read the writing on the wall.” That was IPCC chairman Rajendra Pachauri in [...]

The media has paid disproportionate attention to an error in the monumental 2007 report of the Intergovernmental Panel on Climate Change.  In a chapter surveying the possible future impacts of climate change on the Asian region the report included a prediction that the Himalayan [...]

Fight back, scientists urged

The information that is important in making the decisions as to how to manage our world is unequivocal and must be advanced, not as questions at the edge of scientific knowledge where [...]

Al Gore going strong

by Bryan Walker March 1, 2010

That travesty of a news outlet, Fox News, carried an article last Thursday (in its science and technology section, believe it or not) which opened as follows: “Al Gore won a Nobel Prize and an Oscar for his film, An Inconvenient Truth. But in the last three months, as global warming has gone from a [...]
