The main driver of climate change is
the greenhouse effect
. Some gases in the Earth’s atmosphere act a bit like the glass in a greenhouse, trapping the sun’s heat and stopping it from leaking back into space and causing global warming.
What is the leading cause of climate change?
The evidence is clear: the main cause of climate change is
burning fossil fuels such as oil, gas, and coal
. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up.
