Causes of Climate Change
Natural causes
-
Volcanic eruption
When volcano erupts, large volumes of CO2, water vapour. SO2, dust and ash are released into the atmosphere.

Human causes
Deforestation
-
WIth deforestation, there are fewer trees and other plants to absorb carbon dioxide, leading to an increase in carbon dioxide levels in the atmosphere.
Carbon dioxide is also emitted during the process of deforestation and land clearance.
Trees are removed for...
(i)To make products such as papers and building materials
(ii)To clear the area for mining activities, the grazing of animals, the planting of crops and the construction of infrastructure.
Between 2000 and 2010, 52000 sq km of forest was lost every year.
The greatest overall loss of forests occurs in South America. The need for developments(cattle ranching, soybean production, commercial logging and mining) is the cause of forest clearance.

-
Fossil Fuel
It is formed from dead organic matter that has decomposed over many millions of years. E.g. oil, coal and natural gas
Due to its high carbon content, fossil fuels contribute to the increase in greenhouse gases by producing large amounts of carbon dioxide when burnt
Large consumers of fossil fuels : China, the United States of America, Canada and United Kingdom
The world's usage of fossil fuels has increased in recent years, releasing billions of tonnes of carbon dioxide into the atmosphere each year
-
Agriculture
The practice of cultivating land, the third highest contributor of greenhouse gases
-
-
-
Industries
-
-
-
These days, countries such as China and India are contributing more to global carbon dioxide emissions due to their rapid industrialisation.
-
-
Urbanisation
-
-
The high concentration of cars, buses and other forms of transportation in urban areas also contributes to the amount of greenhouse gases emitted in these areas
Additionally, constructing infrastructure and producing construction materials also release greenhouse gases into the atmosphere
