Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years.
CAUSES OF GLOBAL CLIMATIC CHANGE
Both natural and human factors change earth’s climates
Since the industrial era began humans have had an increasing effect on climate particularly by adding billions of tons of heat-trapping greenhouse gases in the atmosphere.
Most of the observed warming since the mid 20th century is due to human-caused greenhouse gas emission.
CONSEQUENCES OF GLOBAL CLIMATIC CHANGES
- Loss of biodiversity, since when the climate change there is occurring of drought that can cause plants and micro-organism die
- Causes disease such as skin cancer, when the ozone layer is destructed it can cause the sun rays to penetrate directly to the earth surface since the ozone layer previously acting as a blanket to prevent the sun rays is now destructed.
- Famine or hunger. It is difficult to practice agriculture when climate is changing. it may cause drought making it difficult for plant growing
- Increase in sea levels since the climate change can cause the melting of ice due to increase in temperature on the earth surface that cause increase of the sea level.
- Loss of habitat for living organismsince there are some living organisms living in cold areas or in ice so when the climate changes due to increase in temperature those organism fail to survive and die.
