While consensus among nearly all scientists, scientific organizations, and governments is that climate change is happening and is caused by human activity, a small minority of voices questions the validity of such assertions and prefers to cast doubt on the preponderance of evidence. But there is a worldwide agreement on the fact that climate change is real.

In this part , we’ll be talking about the causes of climate change :

 The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide. The increase in the number of vehicles and the over consumption of electricity also uses the fossil fues emitting greenhouse gases into the atmosphere.

 Deforestation is the second leading cause of global warming and produces about 24% of global greenhouse gas emissions. Scientist say that deforestation in tropical rainforests adds more carbon dioxide to the atmosphere than anything else.

 Research suggests global warming was kicked off partly by the Industrial Revolution in the U.S. and other countries, which occurred in the mid-19th century. Due to fuel combustion there is an increase in the level of carbon dioxide which is a leading factor for the changing climate . The industrialization of agriculture takes the potential negative effects of livestock production and amplifies them.

 There are a number of natural factors responsible for climate change. Some of the more prominent ones are continental drift, volcanoes, ocean currents, the earth's tilt, and comets and meteorites. When a volcano erupts it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere which travels to the upper layer of the atmosphere leading to a blockage.
