Things got a little too warm when Al Gore took to the stage at the SXSW Interactive festival Saturday to talk about The Future — that is, his new book subtitled Six Drivers Of Global Change as well as the NRA, the internet and global warming, natch. AllThingsD editor Walt Mossberg took the opportunity to call the former VP on an inconvenient truth — not his movie, the hypocrisy of his sale of Current TV to Al Jazeera. “You sold your network to Al Jazeera, which is owned by a government that’s a big oil producer,” asked Mossberg. “How could you do that?” Gore eventually responded “I don’t ask you why you continue working for Rupert Murdoch.” Uh-oh. Mossberg parried, “Last I checked, he’s not in the oil business”. Gore retorted, “He’s also not strictly in the news business, either”.
