This graph is total nonsense without further explanation or better legends. It might make sense to its creator, but it is hard to imagine anyone else getting any benefit whatsoever from it.

1. It talks about "monthly averages" in the caption, but there's nothing about months in the graph.

1. It looks funny, like it is a series of blue ovals inside black ovals. Spread out more in the horizontal direction, it might be comprehensible.

1. Nothing identifies what is northern hemisphere and southern hemisphere.

1. The scientific notation legend is will put non-technical people off. Just use square megameters, with numbers 5, 10, 15, and 20. Or even millions of square kilometers, with the same numbers.

1. Just what in the world are you trying to show with it? Maybe explaining that will make it make sense. Gene Nygaard 21:22, 15 Apr 2005 (UTC)
