based on the data above which of the following is a most likely conclusion of a study, addressing the following scientific question. What will happen to methane levels in the atmosphere at 60° N to 75°N latitude from 2018 to 2027 if the trend from 2011 to 2017 continues

methane in the atmosphere will increase because melting, or permafrost will lead to an increase in the amount of organic matter that will decompose

Based on the data above which of the following hypotheses about the future conditions in the Arctic is most plausible if the trend seen from 2011 to 2017 continues
