Humans or Nature?
Climate Changes
My Argument
I believe that human activity is actually causing most of the climate changes. These pros and cons explain my reasoning.
Pros:
Human-produced carbon dioxide (CO2, a greenhouse gas and a gas humans exhale) is warming the Earth, not natural CO2 released from the ocean and other "carbon sinks", such as forests.Human green house gases will continue to accumulate in the atmosphere causing climate change because the Earth's forests and oceans cannot adequately absorb them all. Carbon sinks are only absorbing about 50% of human-produced CO2. The other 50% is accumulating in the atmosphere.Nearly all climate change studies show humans as the main cause, and studies which contradict this claim are often funded by petroleum companies, and makes their conclusions suspicious because of the obvious confict of interest.Cons:Many organizations believe that nature, not human activity, is primarily responsible for climate change.Changes in ocean currents are primarily responsible for the melting Greenland ice sheet, Arctic Sea ice, and Arctic permafrost.Deep ocean current cause climate warming and cooling in long-term cycles. The minor Greenhouse Effect of human-produced CO2 pales in comparison.
