Carbon

By Isabella Ossiander

CO2 is a greenhouse gas that traps the heat and energy from the sun in the Earth's atmosphere. This is considered a good thing at the proper levels because it keeps our oceans from freezing over. However, the data has shown that CO2 levels have increased past the average of 280 parts per million since 1950 and has now reached an extreme level of 394 parts per million.

Over the past 200 years the ocean has become more acidic, having absorbed around 500 billion tons of CO2. The ocean absorbs more than one quarter of the greenhouse gases in Earth's atmosphere, without the ocean absorbing so much CO2 Earths average temperature would be much higher and the Artic ice would be melting much faster. Now with the ocean absorbing so much CO2 it is becoming more and more acidic and for some sea creatures, like oysters and clams, too much acid stops them from being able to form a shell and soon causes them to die.

Over the last 100 years evidence shows us that Earth's CO2 levels in our atmosphere have increased because of humans burning fossil fuels, such as coal and oil.

Temperature records indicate that Earth's average temperature has increased rapidly in the past 50 years. CO2 levels have increased correspondinly to the temperature increases. Since CO2 is considered a greenhouse gas it traps the heat in Earths atmosphere which results in global climate change.
