Potential solutions range from sea barriers to changes in farming and land-use planning practices as well as changes in individual food and recreation choices, according to the report's authors. As for climate-change mitigation, the third IPCC Working Group will release its report next month, with suggestions ranging from burying the carbon dioxide emitted by fossil fuel–fired power plants to conserving energy in general. "We need a lot more focus on adaptation and mitigation and, in developing countries, on developing resilience," Rosenzweig says. "We are now moving towards a solutions phase."
