The iconic yellow-bordered magazine, beset by financial issues, entered its own uncharted territory. In an effort to stave off further decline, the magazine was effectively sold by its nonprofit parent organization to a for-profit venture whose principal shareholder is one of Rupert Murdoch’s global media companies.
In exchange for $725 million, the National Geographic Society passed the troubled magazine and its book, map and other media assets to a partnership headed by 21st Century Fox, the Murdoch-controlled company that owns the 20th Century Fox movie studio, the Fox television network and Fox News Channel.
Stockman also said he “can’t get answers” to how long it would take for the sea level to rise two feet. “Think about it, if your ice cube melts in your glass, it doesn’t overflow. It’s displacement. This is some of the things that they’re talking about that mathematically and scientifically don’t make sense.”
Holdren wasn’t given a chance to answer this question, but the answer is pretty simple. Stockman seems to be forgetting that not all melting ice is already in the sea. Melting land ice — glaciers, ice sheets, ice caps, and permafrost — are the major contributors to global sea-level rise as their water flows into the ocean. And even though melting sea ice doesn’t directly contribute to sea level rise, it does cause ocean temperatures to rise. This causes the ocean to expand and rise — a big component of sea level rise — and the added heat can ultimately cause more land ice to melt.
The exchange ends with an awkward silence over the length of ice ages, and Stockman eventually getting interrupted by the committee’s sitting chair to move on with the hearing.
