As the planet warms, and rain and storm patterns change dramatically, many species will find themselves in climate zones that no longer support their survival. Some can migrate, but others (such as polar bears) are likely to be driven to extinction unless we take decisive action to head off climate change.
最后，各国应该在不迟于2010年谈判一项新的框架来减缓人为引起的气候变化。毫无疑问，气候变化是物种生存最大的威胁之一。当地球变暖、 降雨和风暴模式大幅度改变之际，许多物种都会处于不再支持其存活的气候区域内。某些物种可以迁徙，但是，除非我们采取决定性的行动来阻止气候变化，其他的物种(例如北极熊)就有可能遭到灭绝。
