自然生态系统通常被认为是最容易受到快速气候变化负面影响的部门之一。澳大利亚丰富的生物多样性已经受到多种人类影响的相当大的威胁，气候变化将带来额外的压力。由于澳大利亚自然环境和生物环境的一些特点，包括地形、生境破碎化、扩散能力低和许多物种的地理范围有限，大多数澳大利亚物种通过改变其分布来适应气候变化的机会将受到限制。这篇综述总结了澳大利亚最近和预计的气候趋势，并讨论了物种如何在特定的环境特征和大陆的地理历史背景下对这些变化作出反应。它还确定了在短期至中期内可能受到最不利影响的特定区域和生态系统。
Natural ecosystems are generally considered to be one of the most vulnerable sectors to negative impacts from rapid climate change. Australia's rich biodiversity is already under considerable threat from multiple human impacts, and climate change will impose additional stress. Opportunities for most Australian species to adapt to climate change by altering their distribution will be limited due to a number of characteristics of the Australian environment, both physical and biotic, including topography, habitat fragmentation, low capacity for dispersal and the restricted geographic ranges of many species. This review summarizes recent and projected climate trends in Australia and discusses how species may respond to these changes in the context of the particular environmental characteristics and biogeographic history of the continent. It also identifies particular regions and ecosystems likely to be most negatively affected in the short to medium term.
