Contrails And The Dark Side
In order to curb global warming it's likely we'll need to make a number of lifestyle sacrifices. Arguably, one of the most inconvenient of these would be air travel. Jets certainly pump out their fair share of greenhouse emissions, which would be reason enough to consider cutting back air travel, but jets add to global warming in yet another way. The long trails of condensation known as contrails emitted by jet airliners are now considered to be a significant factor in global warming. Furthermore, a group of UK meteorologists recently found that night flights make contrail troubles considerably worse...
