Abstract: The climate change issue is increasingly receiving attention from scientists, public, and policy makers. The United Nations Convention on Climate Change defines climate change as ‗‗a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is, in addition to natural climate variability, observed over comparable time periods‖. Greenhouse gases and many air pollutants have known common sources, contribute to radiative balance, interact in the atmosphere, and affect the ecosystems. The study of the impacts of both air pollution and climate change on plant ecosystems may significantly differ from a sum of separate effects. This chapter reviews the links between air pollution and climate change and their interactive effects on plants. A simultaneous addressing of the air pollution and climate change effects on plants may result in more effective research, management and monitoring, as well as a better integration of local, national and global environmental policies.
