USA Today, 12/19/2006.

"Aviation and the environment are on a collision course. The number of
airline flights worldwide is growing and expected to skyrocket over the
coming decades. Aircraft emissions pollute the air and threaten by 2050
to become one of the largest contributors to global warming, British
scientists have concluded."
