a&b
The graph shows the steady rise of CO2 in the atmosphere from 314ppm in 1957 to 403ppm in 2016. The rise appears to be exponential with little variation in the month on month measurements.
I’m not sure what is meant by ‘seasonally adjusted’ in the notes.
c
The amount of CO2 in the atmosphere has increased by about a quarter
d
Extrapolating on the information on the graph I would expect the information to increase to double the 2016 value; i.e. c.800 ppm by 2067.
e
It doesn't show any signs of a slowing or halting of the increase in CO2. The graph also makes no attempt to extrapolate of forCast into the future.
f
You could ask:
Why does the scale start at 310 ppm and not 0
Or, why the x axis starts at 1957 and not further back.
Or, is there another data series that confirms these observations from elsewhere in the world
Or, could you attempt to correlate the data with a cause, such as increase in local car ownership
