Causes of Global Warming







There are many causes of global warming. Greenhouse gases, cars and fossil fuels are just a few of the factors that cause global warming. I will now examine some causes about this statement.

One of the most important reasons for this problem is greenhouse gases. What I mean is that the greenhouse gases traps heat from the sun so the temperature rises in the world. A second important issue is cars. This is because cars release CO2 and many people are making short trips by their cars instead of walking or using public transport. Another point is fossil fuels. To elaborate, fossil fuels burn to run cars and trucks, heat homes and power factories. Finally, burning forests are also reason to increase the temperature.
