The atmosphere was originally formed from volcano gasses and no oxygen was present. However, about 2.2 million years ago cyanobacteria started to photosynthesize and oxygen levels began to increase.

Which is not a natural cause of climatic change?

Human activities such as burning fossil fuels and deforestation are not natural causes of climatic change. These activities release greenhouse gases into the atmosphere, leading to the enhanced greenhouse effect and global warming.


Why is it difficult to identify any single cause of climate change?

It is not difficult. The one single cause of climate change is global warming. There are several causes of global warming, but the two main causes are the burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which used to remove carbon dioxide (CO2) from the atmosphere). Both these mean more greenhouse gases in the atmosphere, and this is what is causing global warming which is causing climate change. Not difficult to identify at all!

What could cause climate change?

It is generally accepted that the increasing amount of carbon dioxide in the Earth's atmosphere is the cause of climate change. Many different factors affect the carbon dioxide level, but the burning of fossil fuel (coal, oil, natural gas) seems to be the most important factor.
