Antarctic Sea Ice At 35-Year Record High On Saturday

Antarctic sea ice has grown to a record large extent for a second straight year, baffling scientists seeking to understand why this ice is expanding rather than shrinking in a warming world.

On Saturday, the ice extent reached 19.51 million square kilometers, according to data posted on the National Snow and Ice Data Center Web site. That number bested record high levels set earlier this month and in 2012 (of 19.48 million square kilometers). Records date back to October 1978.

The increasing ice is especially perplexing since the water beneath the ice has warmed, not cooled.

“The overwhelming evidence is that the Southern Ocean is warming,” said Jinlun Zhang, a University of Washington scientist, studying Antarctic ice. “Why would sea ice be increasing? Although the rate of increase is small, it is a puzzle to scientists.”

In a new study in the Journal of Climate, Zhang finds both strengthening and converging winds around the South Pole can explain 80 percent of the increase in ice volume which has been observed.

“The polar vortex that swirls around the South Pole is not just stronger than it was when satellite records began in the 1970s, it has more convergence, meaning it shoves the sea ice together to cause ridging,” the study’s press release explains. “Stronger winds also drive ice faster, which leads to still more deformation and ridging. This creates thicker, longer-lasting ice, while exposing surrounding water and thin ice to the blistering cold winds that cause more ice growth.”

But no one seems to have a conclusive answer as to why winds are behaving this way.

“I haven’t seen a clear explanation yet of why the winds have gotten stronger,” Zhang told Michael Lemonick of Climate Central.
