Icebergs cause civil aviation headache

Icebergs have recently been spotted off the coast of New Zealand. A cottage industry as emerged overnight as pilots fly tourists on sightseeing excursions to see the icebergs.

There is debate as to whether an increased prevalence of icebergs in warmer water could be an indication of global warming, a position held by Al Gore in his film An Inconvenient Truth. On the other hand, global warming skeptics here might say that these are merely chance occurrences due to certain weather conditions.
