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.
The burning of fossil fuels in the conversion to energy creates waste of H2O and CO2. While CO2 is a natural greenhouse gas, too much of it in the atmosphere has been proven to cause global warming. Last year, emission of CO2 from fossil fuels was 6.2 billion tons, increasing fourfold from 1950 (Flavin and Dawn, 113).
