The Blaze, yeah count on them for some real science. LOL!
You don't need to be a rocket scientist, or any kind of a scientist, to grasp this simple concept:

Antarctica Is Gaining Ice, So Why Is the Earth Still Warming?

NASA recently released a study suggesting that the Antarctic Ice Sheet is gaining more ice than it is losing — a finding that, at first blush, seems to contradict the idea of global warming. So, how can Antarctica be gaining ice mass in a warming world where ice sheets are collapsing and the melting is predicted to increase sea levels across the globe?
It turns out that the two phenomena — a growing ice sheet and warming-related melting — are not mutually exclusive. Moreover, the NASA study, which was published Oct. 30 in the Journal of Glaciology, does not disprove global warming.
Trends over time
Other research has started to look at older records of Antarctica's climate, in order to place current data into historical context. Doing so can help scientists better understand how current observations fit into the larger story of Antarctica's climate. In a separate study, published Nov. 4 in the journal Geophysical Research Letters, researchers studied the climate of West Antarctica over the past three centuries by looking at ice core records. The researchers found that snow accumulation in the 20th century had been significantly higher than in the previous two centuries looked at in the study.
"It looks as though [this trend] is related to there being more storms [in West Antarctica]," said Thomas, of the British Antarctic Survey. "Just because [West Antarctica] is getting more snow doesn't mean that [the ice sheet is] getting thicker."
She explained that both higher snow accumulation and thinning ice sheets are results of the same regional warming phenomenon. The amount of precipitation is tied to the amount of sea ice in the region. "When we had a lot of sea ice, we don't have so much moisture," she said.
