Scientists believe that the absorption of carbon dioxide in the atmosphere by the ocean temporarily eases the rise of carbon dioxide concentration, and once this mitigation effect fails, the concentration of carbon dioxide in the atmosphere will increase at a faster rate. So, will the increased carbon dioxide cause the atmospheric temperature to rise? Although most scientists believe the answer is yes, this is a long process with many variables, so climate change skeptics have been writing on this point, trying to convince ordinary people that carbon dioxide concentration is not necessarily related to atmospheric temperature. This strategy is so effective that many people today still refuse to believe that human activities are responsible for global warming, and therefore refuse to participate in reducing emissions. What this text is most likely to say next is:. ['Climate change has little to do with carbon dioxide concentration.', "Ocean's ability to absorb carbon dioxide is getting weaker.", 'Human activity causes an increase in carbon dioxide concentration.', 'Human activity is the main cause of global warming.']
