Of course when you apply dittohead spin the message is inverted.

Err.. the message is the same.
The article said the ice formed at 600ppm.
It said its 390ppm now.
It isn't likely to have melted until it hits 600ppm.
Where is that different to what you say?

The report suggests that 600ppm is the threshold below which ice began
to form at the South Pole. The one thing we can be sure of on that basis
is that if/when that level is again reached there will still be plenty
of ice in Antarctica but that is a very different situation to that
implied by Lewis Page's "Not going to melt any time soon, says boffin".
Melting is already under way and it won't take a very big percentage of
the total ice mass turning to water to seriously embarrass major cities
like London or swamp the low lying Pacific islands or a significant part
of Pakistan.
