The 2007 assessment report by the United Nations Intergovernmental Panel on Climate Change (IPCC) confirms that it is virtually certain that human activities (mainly through the use of fossil fuels and land development) have been responsible for the global warming that has taken place since the industrial revolution. Under current economic and social trends, the world is on a path to unprecedented ecological catastrophes.1 As the IPCC report was being released, new evidence emerged suggesting that climate change is taking place at a much faster pace and the potential consequences are likely to be far more dreadful than is suggested by the IPCC report.
