The assessments of the likely outcome of the Copenhagen climate change talks seem to get gloomier by the day. The preliminary chats by the bureaucrats from the nations of the world appear to be making very slow progress. Already it seems to be accepted that there will be no binding Treaty agreed to when their bosses get together at the end of the year. This weekend the head of the international group leading the fight againstclimate change sounded downright gloomy as he spoke on the eve of a final round of negotiations being held in Barcelona. Rajendra Pachauri, head of the Intergovernmental Panel on Climate Change accused countries of pushing science aside in favour of self-serving “political myopia” ahead of the vital Copenhagen summit.
