"Fossil fuel burning and deforestation have emerged as principal anthropogenic source of rising atmospheric CO2 and the consequential global warming. Variability in temperature, precipitation, snow cover, sea-level and extreme weather events provide collateral evidence of global climate change. I review recent advances on causes and consequences of global climate change and its impact on nature and society. I also examine options for climate change mitigation. Impact of climate change on ecology, economy and society?the three pillars of sustainability?is increasing. Emission reduction, although most useful, is also politically sensitive for economic reasons. Proposals of the geoengineering for iron fertilization of oceans or manipulation of solar flux using stratospheric scatters are yet not feasible for scientific and environmental reasons. Forests as carbon sinks, therefore, are required to play multifunctional role that include, but are not limited to, biodiversity conservation and maintenance of ecosystem functions; yield of goods and services to the society; enhancing the carbon storage in trees, woody vegetation and soils; and providing social and economic well-being of people. This paper explores strategies in that direction and concludes that the management of multifunctional forests over landscape continuum, employing tools of conservation biology and restoration ecology, shall be the vital option for climate change mitigation in future."
