Climate change conference

December 1, 2008 - December 12, 2008 - The UN holds a conference on Climate Change in Poznan, Poland. Greenhouse gas emissions by 40 leading industrialised nations have dropped an average of 5% below 1990 levels, mostly due to economic decline in eastern European countries in the 1990s. But the UN warns that an upward tick for industrial and developing nations between 2000 and 2006 threatens to undo the previous drop.
