There are numerous possible reasons for UN climate chief Yvo de Boer’s decision to resign—from his inability to cobble together a new climate treaty last December in Copenhagen (where he wept on the podium), to recent revelations of his agency’s mishandling of climate change data.

What the climate science community and the public should focus on now are the ramifications of de Boer’s resignation.  For one thing, it signals that hope is dead for a UN-brokered global treaty that would have any meaningful effect on global temperatures.  It also means that the UN intends to keep its Intergovernmental Panel on Climate Change pretty much intact under the leadership of the scientifically compromised Rajenda Pauchari, who should have resigned along with de Boer.

This development guarantees that the Obama administration will have an unmitigated mess on its hands when signatories to the Framework Convention sit down in Mexico City this November in yet another meeting intended to produce a climate treaty.  The Mexico City meeting convenes six days after U.S. midterm elections, in which American voters are fully expected to rebuke Obama for policies including economy-crippling proposals to combat climate change.

In short, Mexico City is about as likely to produce substantive policy decisions as the TV show ‘The View.’  Backers of radical climate change measures are now paying the price for over two decades of telling the public—in this case literally—that the sky is falling.
