- 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 plot,date,sealevel,th=th,/xs,xtitle='Kyr before present',ystyle=8,ytitle='Sea le vel (m)' axis,/yax,/save,yrange=[0,10],ytitle='mm/y',col=3 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 if (i gt 0) then plots,col=3,th=3,[1,1]*date(i),[d,dold] dold=d endfor gettwogifs,out='~/np/wmc/sealevel' end
