Increasing greenhouse gas concentrations are expected to have significant impacts on the world's climate on a timescale of decades to centuries. Evidence from long-term monitoring studies is now accumulating and suggests that the climate of the past few decades is anomalous compared with past climate variation, and that recent climatic and atmospheric trends are already affecting species physiology, distribution and phenology.
预计在几十年到几个世纪的时间尺度上，不断增加的温室气体浓度将对全球气候产生重大影响。长期监测研究的证据正在不断积累，表明与过去的气候变化相比，过去几十年的气候异常，而且近期的气候和大气趋势已经在影响物种的生理、分布和物候。
