In preparation for emissions control discussions this summer in Bonn, some 100 governments are reviewing a climate change report released this month in Ghana by the Intergovernmental Panel on Climate Change. It calls for quick mandating of “the many available cost-effective solutions” to greenhouse gas emissions.

The 1,000-page report warns: “The relevant question is not ‘what is the best course for the next 100 years,' but rather, ‘what is the best course for the near term.’” It adds, however, the world community can accommodate rapid change because of recent advances such as hybrid car engines and fuel cell technology. Expectations are developed countries will be asked to make the most significant concessions.
