Excuse me if I get this wrong, but isn't this "understanding" subjective to the interpretation of said data.
It would be interesting to know how much this project cost the taxpayers.
This project didn't cost the U.S. taxpayers anything (it's a British Antarctic Survey project).
Of course it does, but it's alot better than the liberal method of drawning conclusions and making "predictions" with no data at all.
As far as cost goes, not much compared to all to the cost of the "environmental impact" statements and such required before anybody can do much of anything, which in turn pales in comparison to the cost of welfare, or even welfare fraud.
