This is some lead, Washington Post:
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.
The world hasn’t actually been “warming” for the past 15 years or so. But let’s not let reality intrude into “settled” science.
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 growth doesn’t fit the models, yet no one is ready to junk or change the models…
“This modeled Antarctic sea ice decrease in the last three decades is at odds with observations, which show a small yet statistically significant increase in sea ice extent,”says the study, led by Colorado State University atmospheric scientist Elizabeth Barnes.
A recent study by Lorenzo Polvani and Karen Smith of Columbia University says the model-defying sea ice increase may just reflect natural variability.
If the increase in ice is due to natural variability, Zhang says, warming from manmade greenhouse gases should eventually overcome it and cause the ice to begin retreating.
“If the warming continues, at some point the trend will reverse,” Zhang said.
