The Albuquerque Journal reports that the pro-green, antinuke message that Mikhail Gorbachev is expected to deliver during a speech in Santa Fe next month will come perhaps at a fitting time for northern New Mexico. While Gorbachev prefers to deliver his remarks from notes jotted down on a notepad, an associate said environmentalism and nuclear disarmament -- both hot topics in the City Different -- will likely be themes of a lecture he'll give during an April 14 visit, which is a fundraiser for the Santa Fe Institute. "He's called for the abolition of nuclear weapons," said Matt Peterson, head of Global Green USA, the U.S. affiliate of Green Cross International, which Gorbachev founded in 1993.
