What is climate change?

 Climate change refers to long-term changes in temperatures and weather patterns. These changes may be natural, but human activities have accelerated the process of climate change through the burning of fossil fuels such as coal, oil and gas. The burning of fossil fuels generates greenhouse gas emissions, which act like a blanket around the Earth, trapping the sun's heat and raising temperatures. Examples of greenhouse gas emissions that cause climate change include carbon dioxide and methane.
