Firstly we will look at the side of the argument that believes that climate change and its effects are not caused by humans and are just a natural occurrence. Most attribute this idea due to the cyclic nature of the earth’s climate, which changes around every …show more content…
As of 2010 the CO2 levels were 389 parts per million, the highest it has ever been since the last 650,000 years. They say that this large rise of CO2 can’t possibly be part of a cyclic nature as the CO2 levels skew much higher than the range of standard deviation. It was found that in the last 650,000 years the CO2 levels have never risen past 300 PPM, but after 1950 there was a sudden rise of CO2 (100 PPM higher than the previous peak) that directly relates to the rise of man-made CO2. They also disprove that the rise of CO2 cannot be caused by “carbon sinks” as the recent large amounts of CO2 were found to contain a different isotopic ratio than CO2 produced from the ocean. It was also found that an excess amount of human produced CO2 had been absorbed into the ocean causing the acidity levels to rise up to 30% more than it was before humans started using fossil fuels. Whenever humans burn fossil fuels in order to acquire power we release a large amount of CO2 which leaves a specific “fingerprint” that is different to regular CO2 that is produced from nature. These are just some of the evidence that supports that humans did play a vital role in global
