Climate talks mired again in rhetoric THE direction of UN climate change talks is repeating the mistakes of the failed 2009 Copenhagen conference, with serious implications for Labor if they continue to support the carbon tax. The latest round of UN talks concluded yesterday in Warsaw, Poland. While there are always declarations of "breakthroughs" and "progress," the seemingly uneventful talks were focused on technicalities and broad themes to inform the conclusion of a post-2020 international carbon-cutting treaty by the 2015 summit in Paris.
