Heartland Conference vs AGU Conference

The difference:

American Geophysical Union Fall Meeting, San Francisco, December 2013 and 2014: press pass granted to denier and blogger Anthony Watts.

versus

Heartland Institute Annual Conference, New York, June 2015: withdraws media credentials for Brendan Montague, editor of DeSmog UK and member of the UK's National Union of Journalists, and has hotel security throw him out, because, he was told, of negative reporting of the Heartland press conference in Rome

One complains about the liberal assault on "free speech." The other simply practices it.
