Is the Antarctica Melting or Not?

Alright, what is it?  Is Antarctica’s ice shelf expanding or dissolving?  Within less than a week, we’ve had conflicting reports as to what is happening to the world’s southern continent. 

NASA recently reported the outer ice shelves are melting at an alarming rate, supposedly due to global warming.  International Business Times reported the following:

In 2002, two-thirds of the Larsen B Ice Shelf, located along the east coast of the Antarctic Peninsula, collapsed in a span of less than six weeks. According to a new NASA study, the remains of this ancient structure, which has existed for over 10,000 years, are likely to disintegrate completely before the end of the decade -- an event that would significantly contribute to global sea level rise.  
“These are warning signs that the remnant is disintegrating,” Ala Khazendar from NASA's Jet Propulsion Laboratory in Pasadena, California, who led the study, said in a statement. “Although it’s fascinating scientifically to have a front-row seat to watch the ice shelf becoming unstable and breaking up, it’s bad news for our planet.”
Several recent studies have spotted an uptick in the melting of Antarctica’s floating ice shelves, which act as doorstops and hold back its glaciers and ice sheets from spreading outward into oceans. In some regions, the thickness of these shelves has fallen by as much as 18 percent over the past 18 years -- a process that has accelerated over the last decade

 And then we have the following contradictions, as reported by The Guardian:

Sea ice around Antarctica is currently at record levels for May, part of a trend of increasing ice around the frozen continent making it harder to resupply and refuel research stations.
More than 50 scientists are gathering in Hobart in Tasmania this week for a series of workshops on techniques to more accurately forecast sea ice levels in the polar region, aiming to save millions of dollars in shipping costs.
They will also hope to avoid a repeat of the problems suffered by the Akademik Shokalskiy, the research vessel caught in a sudden freeze in December 2013. 
Rod Wooding, from the Australian Antarctic Division, said last year ships “couldn’t get anywhere near” the Australian research site, Mawson station, requiring a year’s worth of supplies and fuel to be flown in by helicopter.
“[That] is inadequate for the long-term sustainability of the station,” Wooding said. “Other national programs have had similar problems, the French in particular, the Japanese also.”
Scientists were initially puzzled by the increasing sea ice around the continent, which reached record levels in September 2014, but have concluded it is “very largely driven by changes in wind”, Tony Worby, the chief executive of the Antarctic Climate and Ecosystems Cooperative Research Centre said

What are we to believe?  Is the Antarctic melting or not?  One wonders where the truth lies.  We must consider the possibility that NASA has been corrupted by global warming grafters as have other governmental agencies.  It’s a shame science has been politicized.
