Here is the chart: Chart

My questions are:

  • Is the atmosphere in equilibrium over this record?

  • how would I determine what the maximum and minimum values for each record is (approximation).

  • Is there a correlation between records for CO2, CH4 and temperature?

  • Are today's values within the normal range of variability for this record?

Thank you

  • $\begingroup$ @arkaia I suppose digitizing. All I have is the graph. $\endgroup$

  • $\begingroup$ If you digitize, then you have the answer to questions 2 and 3 $\endgroup$

  • $\begingroup$ @arkaia I want to know if the atmosphere in this chart is in equilibrium, such as is it periodic, like at natural equilibrium to a fixed position, or is in not in equilibrium because maybe there a forcing at play and if so what is it? $\endgroup$
