A Review on Effects of Climate Change on Plants and Ecosystems and Certain Approaches for Plant Response Studies under Climate Change Scenario with Specific Focus on FACE

Global climate change is a ground reality and a continuous process that needs to be taken seriously. Climate change is a serious challenge faced by all flora and fauna on earth. Two main implications of climate change are the rise in atmospheric CO2 and increase in global mean temperature. It has already affected plant diversity, as demonstrated by changes in species distribution, creation of new assemblage of plants, changes in population structure near to coastal zone and extinction of several endemic plants. It also has a major impact on the productivity of agricultural and horticultural crops, forest and land degradation, freshwater shortage, and offers a great research challenges to the scientists. A comprehensive knowledge of plant responses are needed against the projected concentration of CO2, possible at the end of this century. This will be helpfulto understand how the plants are currently responding and how they could be adapted in changing scenario.
