The negative effects of climate change grow with time and threaten the very existence of both human beings and our planet’s unique biodiversity. Climate change is the transformation in the distribution patterns of weather or changes in average weather conditions of a place or the whole world over long periods.

The change can be positive, where there is an observed increase in average measurements of weather conditions, or negative, where a decrease in weather conditions is observed. Both of these changes have negatively affected the earth largely (Hardy, x). Such changes in climate have become a major global problem
Climate changes have many causes. These changes can be natural or those caused by man. All these lead to increase in green house gases in the atmosphere, which disrupt the balance they keep on the atmosphere. Such natural causes include solar variations, ocean currents, volcanic eruptions and changes in the earth’s tilt on its orbit (Hardy, 62).
Human causes come about through agriculture, industry, transport, and use of various forms of energy at home. All these can cause small but critical changes, which can lead to effects like global warming.
Effects of climate change are far reaching. They can be in physical, ecological or economic spheres. In the physical sphere, climate change can lead to increase in global temperatures, extreme weather adulteration of important biogeochemical cycles like the carbon cycle.
In the social system, climate change affects settlement patterns and distribution of people, agricultural production declines, and, thus affects food supply (Doering, 1). This in turn has a negative effect on the economic status of the people who have to incur much expense to mitigate these effects.
In conclusion, there are many negative effects of climate change caused by both natural forces and man’s activities. Human activities contribute substantially to climate change and this in turn destroys his ecosystem, activities, biodiversity and livelihood at large.
