Responding to Climate Change

 As a factor in the natural environment, climate not only affects world patterns of vegetation, soils, and water resources, but also directly or indirectly influences every human endeavor. Climate determines an area's suitability for settlement and for agriculture, manufacturing, transportation, and other economic activities. Knowledge of past climate fluctuation has helped to explain ice ages,changes in sea level,famines and migration .Increasing evidence indicates that human impact on the environment is causing local and perhaps world wide changes in climate.                                                                               The elements of climate chance through time as well as from place to place. Indirect evidence of climatic trends in the distant post is revealed in fossils, lake and ocean beds, peat bogs, glacial deposits, and soils. Archaeological remains and written history offer clues to climatic conditions during the human era, and modern instrument records now provide direct evidence of climate change. :)
