Over the past 200 years the carbon dioxide level has gone up dramatically. At the same time so the global temperature. It has been proven that as the amount of carbon dioxide increases so does the global temperature. The temperature of the earth has gone up and so has the carbon dioxide level, these two relate to one another.

The concentration of carbon dioxide in the air since the beginning of the industrial revolution has increased 30%. That is very high compared to years before. In 1950 the amount of CO2 in the atmosphere was about 315ppm(parts per million). In 2001 it was 375ppm. Since 1950 the amount of CO2 has risen about 1-3ppm per year. The CO2 (carbon dioxide) level could possible rise anywhere from barely getting to 500 ppm all the way up to 1500 ppm (see attached graph). The global temperature had risen over the years too, 2001 had the highest rate of change going up 0.51oc,

which is higher than that of the average temperature from 1880-2000. Since 1980 the temperature raised 0.2 oc per decade. The Global temperature is estimated to rise anywhere from 5 to 9 degrees over the next fifty years. By the year 2030 the temperature will be rising as much as 0.5 oc or more per decade.

The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes. The main gases that cause the greenhouse effect are water vapor, carbon dioxide, and methane. The...
