Climate, science and governance. There was little question last week about the key debates to watch on the sustainable development agenda. Working Group I of the Intergovernmental Panel on Climate Change adopted its Summary for Policy Makers and found that there is more than a 90 percent probability that human action has contributed towards recent climate change, while the eighth African Union Summit discussed climate change implications for Africa. The African Union Summit also designated 2007 as Africa’s year for scientific innovations, while the regional consultation process towards an International Mechanism of Scientific Expertise on Biodiveristy (IMoSEB) got underway, promising to keep science for biodiversity on the international agenda during 2007 as well. French President Chirac pressed for the creation of a UN Environment Organization at the Paris Conference on Global Ecological Governance, while delegates assembled in Nairobi to discuss globalization and governance issues at the UN Environment Programme’s 24th Governing Council/Global Ministerial Environment Forum. In all these processes, we have recorded the opening positions and we will continue to watch as the international community strives to develop associated action plans.
