But how exactly have we caused global warming? Well, when we burn fossil fuels, such as crude oil, natural gas and coal, they emit a gas called carbon dioxide into the atmosphere. The burning of fossil fuels produces approximately twenty-one billion tons of carbon dioxide each year. The Greenhouse effect takes place when there is too much carbon dioxide in the Earth’s atmosphere. The Sun’s rays that heat up our planet are not able to leave the atmosphere due to the carbon dioxide blocking it. Due to this, the Sun’s rays cannot escape, and are constricted to our atmosphere. Over time with all the extra Sun rays, our temperature increases, and global warming occurs.
