Causes of climate change Causes and Consequences of Climate Change Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
First, when fossil fuels (coal, oil, natural gas) are burned, the carbon in them combines with oxygen in the air to form CO2 (carbon dioxide). CO2 absorbs heat being radiated off the Earth that would normally escape into space, warming the atmosphere. Thus, burning fossil fuels cause global warming, resulting in climate change.
