Melting Ice Makes Seas Rise
It’s been around since Archimedes.
Any floating object displaces its own weight.
Now researchers are finding that seas rise as icebergs melt.
A report published this week in Geophysical Research Letters said each year the loss of floating ice is equivalent of 1.5 million icebergs the size of the one that sank the Titanic.
Professor Andrew Shepherd of the University of Leeds was the author of the report that says the rise is spread across all the oceans so so far it’s only about the size of a hair’s breadth. "Over recent decades there have been dramatic reductions in the quantity of Earth's floating ice, including collapses of Antarctic ice shelves and the retreat of Arctic sea ice," said Shepherd.
"These changes have had major impacts on regional climate and, because oceans are expected to warm considerably over the course of the 21st century, the melting of floating ice should be considered in future assessments of sea level rise."
