However, human activities are now increasing the concentration of carbon dioxide in our atmosphere, amplifying the natural warming caused by the greenhouse effect. During the Industrial Revolution, humans began burning coal, natural gas, and oil to power machines for manufacturing and transportation.
It is caused by humans burning fossil fuel (coal, oil and natural gas) and cutting down forests. Both of these mean more carbon dioxide in the greenhouse gases in the atmosphe â¦ re. The extra carbon dioxide is causing global warming, which is causing climate change.his is caused by an increase in atmospheric carbon dioxide levels, resulting principally from our use of fossil fuels such as coal, oil and natural gas, and from the manufacture of cement and deforestation.
