President George W. Bush and other G-8 country leaders have agreed to "consider and adopt" a plan to reduce greenhouse-gas emissions by at least 50% by 2050, as part of a U.N. treaty that will be negotiated in late 2009 in Copenhagen, Denmark. Bush's decision to join in the agreement is the latest sign of a shift in Bush's plan to combat global warming, which major industrialized countries are calling "one of the great global challenges of our time."
