A major event yesterday was a press conference announcing the organization of a massive global warming awareness event called "Live Earth".
"Live Earth is a series of concerts planned for July 7, 2007 (7/7/07) to raise awareness of global climate change. An anouncement was made on February 15, 2007 by former U.S. Vice President Al Gore and other activists as part of a campaign called Save Our Selves (SOS). The concert series is modeled after the 1985 Live Aid concerts and 2005's Live8." (Wikipedia)
