(1) What does the x-axis of the graph represent? Years Ago
What does the y-axis of the graph represent? Estimated Average Global Temperature (ºC)

Thats fine! THX anyway
2) The pattern appears to be sudden increases and decreases of temperatures
3) According to the pattern for the previous 350000 years, I would predict that there will be remain volatile and will go up and down wildly.
