The United Nations on Thursday decided to restrict access to the global climate talks in Copenhagen for non-governmental organisations and it confronted journalists with additional security. The measures were put in place as more than hundred world leaders began arriving in the Danish capital. This politician regretted the move. Jo Leinen So as a quiet tension took hold of the Bella Centre, side-events in the centre of town became more lively. The Klimaforum is one of these. Among the visitors... These three aspiring journalists and bloggers, from Brasil, Italy and Bulgaria. They won a trip to cover the climate talks as part of the ThinkAboutIt dot EU blogging competition. The Klimaforum mostly met the needs of those who are already convinced of the need to deal with climate change. Climate skeptics had their own event at a separate venue. The official negotiations on a comprehensive climate deal continued on Thursday, again without clear progress. Increasingly, observers, analysts and even politicians are admitting that a full-fledged agreement no longer is possible, and suggest such a deal needs to be hammered out in Mexico in six months. But even if that happens, the Copenhagen summit, according to some, will not have been a waste of time and energy. Raymond Frenken, EUX.TV, Copenhagen Distributed by Tubemogul.
