Global warming is the average temperature increase of Earth’s air and oceans. Currently, it is still a theory. Some people do not believe global warming occurs.
3
The cause of global warming comes from the greenhouse effect. Greenhouse gasses, such as CO2, absorb Solar Radiation. Some solar radiation reflects back into the atmosphere, while some gets trapped within the atmosphere.
4
CO2 levels are drastically higher than previously recorded levels. Cities like Shanghai, Tokyo, Bangkok and New York are at risk for flooding. Diseases like Malaria are more likely to occur due to global warming. CO2 emissions can be lowered by using energy efficient devices such as solar power, and wind power machines.

Earth has always cycled from Ice Ages to warm ages. Temperatures have risen faster recently than in the past. Scientists believe that humans are the main cause for the strain of greenhouse gasses. Arctic Sea ice has decreased by 10% in the past 30 years. 1998 was the hottest recorded year. 2005 was the second hottest recorded year. Temperatures are predicted to rise 2 to 10 degrees in the next century. Some species face extinction.

20 th century data on temperature increase is not linked to greenhouse gasses. Some believe that global warming is propaganda. CO2 is not the cause of global warming whether it be man-made or not. There is nothing unusual about the temperature. Scientific evidence is illegitimate.

This is GOOD!! Believe them!
