OSLO - Tides affect the speed at which an Antarctic ice sheet bigger than the Netherlands is sliding towards the sea, adding a surprise piece to a puzzle about ocean levels and global warming, a study showed on Wednesday.


The Rutford Ice Stream of western Antarctica slips about a metre (3 ft) a day towards the sea but the rate varies 20 percent in tandem with two-week tidal cycles, it said. And the effect is felt even on ice more than 40 km (25 miles) inland.
"We've known that (twice-daily) tides affect the motion of ice streams but we didn't know it happened on this two-weekly time scale," said Hilmar Gudmundsson, an Icelandic glaciologist at the British Antarctic Survey.

Tides rise and fall about twice a d

1. Interesting article

I found this part important:

"Some past scientific reports have wrongly interpreted changes in the rate of the ice slide as part of longer-term shifts,"

I'm not arguing against global warming but if scientist go looking to prove something they will prove it. thats why in medicine we have double blind tests.
