Additionally, Bollier further states the contrail emissions to cause warmer weather. The duration of contrails in the atmosphere can last for days, according to (Harris, Kuper, Lebel, 2010). Trails may last for days and spread over hundreds of miles. According to Patrick Minnis, senior research scientist at NASA's Langley Research Center in Virginia, "It helped us get a very good handle on the relationship between natural cirrus clouds and contrails,

Other aircrafts in the category of A380, produced in the last few years, included the A350, Boeing 777, Boeing 787 and the other 747's. GKN and other similarly-motivated companies have been focused on reducing harmful acoustic emissions of aircraft jet engines (Hilpern). UK Prime Minister Tony Blair endorsed the report made by economist Sir Nicholas Stern on October 30, 2006 about the global economy shrinking by 20% because of global

At the time, the industry sought to examine both oil pollution in general and ocean dumping as well as land-based sources of ocean pollution. According to Wang, "More significant was the rapid technological development in the design of large-sized oil tankers which required constant rule changes. By 1973 it was evident that the 1954 convention provisions were inadequate or outdated, and by then the likelihood of the 1954 convention

At the same time, research on ozone depletion showed the dire situation and helped support pushes for reform and regulation of harmful chemicals being used in such a vulnerable context as in our atmosphere. Many Western nations have passed legislation limiting the types of chemicals and levels which are acceptable, for example the Air Pollution Act in the United States (U.S. Environmental Protection Agency 2010). Conclusions With this growing amount of

(Jordans, 2008) "Europe's unilateral approach will only lead to legal battles and trade wars," Bisignani also stressed. (Jordans, 2008) a hint of this contention occurring in the future was evidenced recently when 27 nations, including the U.S., China and 25 other countries, registered opposition to the EU's attempt to include commercial airlines in its cap-and-trade program by supporting an ICAO-run program. This signal confirmed united opposition to the European
