Experts predict that in just 50 years the amount of CO2 will be 500 ppm in the atmosphere thereby causing global temperatures to rise by 2 degrees. This small increase in temperature has the potential for catastrophic results with the ice cap meltdown and the resulting rise in sea levels by about 20 feet.
