Is our home starting to warm? What happens if it does? The issue of global warming is one that could have adverse effects on the way we live our lives. There are some things that must first be understood about global warming before we decide what to do like what it is, what causes it, how is it measured and what are the effects? So what is global warming? Global warming is described as an increase in the temperature of the earth’s surface. The more commonly used definition that is circulated is that global warming is climate change caused by human doings. This “human-caused” warming is called anthropogenic (“Global Warming Definitions”). There are many ways that natural global warming can take place. Greenhouse gases are ones that trap the heat of the earth and reflect it back (“Global Warming Definitions”). Carbon dioxide (CO2) is an example of these. Greenhouse gases are given this name because they act like a giant greenhouse around the earth (“Climate”). These gases can be put into the air as a by-product of what humans use to run their lives. This is the main reason why a lot of people are blaming humans for the warming (“Global Warming Causes”). One source says there are other natural causes such as water vapor which is basically clouds, methane which cows are constantly giving off, and chlorofluorocarbons which used to be found in refrigerators. Even small changes in the output of the sun can change the surface temperature of the earth. There are also some other minor things that can slowly change the temperature of the earth. One of these things is the small change in the earth’s orbit that takes place about every 100,000 years this can cause slow warming and cooling of the earth (“Climate”).
