What are the causes of climate change
Climate change is caused by trapping excess carbon in Earth’s atmosphere. This trapped carbon pollution heats up, altering the Earth's climate patterns. The largest source of this pollution is the burning of fossil fuels (such as coal and oil) for energy.
While carbon has entered the atmosphere for millions of years through natural events such as forest fires and volcanoes, the burning of fossil fuels and clearing of land has resulting in the highest levels of greenhouse pollution in our atmosphere in the last 800,000 years.
