• Black line: sea level (below present) in m.
• Blue line: rate of rise (mm/y).

Created with IDL, data from IPCC TAR archive copy at the Wayback Machine.

Note that this is only a schematic and should not be taken literally. See for example http://www.pol.ac.uk/psmsl/palaeoshoreline_webpage/HTML/Science.htm archive copy at the Wayback Machine for a picture drawn from more realistic data including error estimates.

The IDL code is:

sealevel=[-120,-120,-90 ,-3.5,-.75,-0.3,0]
date=    [-25,-20.,-15.,-6. ,-3  ,0,0.2]

th=5

n=n_elements(date)
for i=0,n-2 do begin
  d=(sealevel(i+1)-sealevel(i))/(date(i+1)-date(i))
  plots,col=3,th=3,[date(i),date(i+1)],[1,1]*d
