There is no room for lethargy in science. There is no excuse for giving up in aggravation. That is the nature of it.

Painstaking effort against relentless aggravation and disappointment of expectations is the lot of all truthseekers.

Watts Up With That?

One of the graphs we have had on the WUWT sea ice page has been the DMI graph showing 30% concentration of sea ice extent, there has been a widening divergence between the two Arctic sea ice extent graphs produced by DMI.  WUWT reader David Burton writes:

Until a few days ago, Denmark’s Meteorologiske Institut (DMI) graphed Arctic sea ice extent two ways. They had a graph comparing the current year to the preceding ten years’ “30%+ concentration” Arctic sea ice extent, with coastal zones masked out, by graphing each year in a different color on the same horizontal timescale.

They also had (and still have) a graph comparing the current year to the preceding four years’ “15%+ concentration” Arctic sea ice extent (and I don’t know how they handle coastal zones in that version). In both graphs, the current (partial) year is plotted with a heavier black line.
