A three-day conference
on climate science and policy that drew some 2,500 scientists, economists, campaigners, dignitaries, industry representatives and journalists to Copenhagen has wrapped up, and organizers have issued a list of core "messages" that you can see at the bottom of this post. Their bottom line, echoing what many climate scientists have been saying with rising vigor for two decades, is that there is an urgent need to curb emissions of greenhouse gases, and "inaction is inexcusable."
Is this effort, which one organizer described as "a deliberate attempt to influence policy
," likely to change things? There are signs, some scientists warned on Thursday, that overheated descriptions of looming dangers coming out of the conference could actually backfire. More on those warnings is below.
