Answer:
(A) Climate Change (B) Climate Change and Plant Communities (C) Effect on Sea Levels (D) Reduction of Biodiversity (E) Effect on Agriculture (F) Effect on Arctic Ecosystems (G) Overall Effect.
Explanation:The increase in temperature will be greatest at high latitudes and over large continents. Climatic changes as a result of global warming will naturally affect the biotic communities on this earth. Rising temperatures will cause glaciers to melt and the polar ice caps to shrink. As mentioned above increased temperatures, inundation of some coastal biological communities and changes in the pattern of distribution of many species over a long period of time are likely to cause reduction in biodiversity in aquatic and terrestrial ecosystems. The global climate change may have important effects on agriculture. Global climate change will have profound effects on arctic ecosystems. The overall effect of global warming on world climate has many dimensions, some of which are discussed above. The natural greenhouse maintains the earth’s temperatures within the limits for physiological functions. But studies suggest that even a moderate increase in the average global temperature could result in significant changes in biotic communities including reduction in biodiversity both in terrestrial and aquatic ecosystems.
