There are many different views on what is causing it, how fast the temperature is rising, and what we can do about it but there is no denying that the environment is going through changes. This is a big issue for everyone on this planet. Many large companies are donating money for research. Television networks are adding a little green to each one of their sitcoms. Also politicians are speaking out and even making documentaries on this severe situation. So what is this global warming and just how severe is it? Global warming is the gradual increase in the earth’s temperature over time caused by the greenhouse effect. The sun puts out short wave light which passes through our atmosphere (greenhouse) then that infrared radiation reflects off the earth’s surface toward space but, it does not easily pass back through the atmosphere. The radiation that doesn’t pass through is absorbed by the earth’s greenhouse gases and is trapped inside the atmosphere. This keeps our planet at an average temperature. With out this cycle our planet would be too cold to sustain life. If this is so, then why is our temperature slowly rising? Many people say the cause is human pollution.
