Climate
change is a significant and
lasting change in the statistical distribution of weather patterns over periods
ranging from decades to millions of years. It may be a change in average
weather conditions, or in the distribution of weather around the average
conditions. Climate change is caused
by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as
significant causes of recent climate change, often referred to as "global warming.
Thus,
man is capable of influencing global climate deliberately or inadvertently
through his various actions and activities.
