On air travel and climate change from the Christian Science Monitor:
"Efficiency is only set to improve at 1 or 2 percent per year at best, while the number of passenger kilometers is growing at 5 or 6 percent," says Peter Lockley, head of policy development at the Aviation Environment Federation, a British think tank. "So emissions are going up steadily in the gap between the two."
On a recent Delta Airlines flight we saw the above advertisement. You'll notice that the leaves in the ad are those of a linden. We wondered why the ad agency selected linden leaves. Aren't maple and oak leaves more recognizable? Hoping to find out more, we searched the internet but did not find any information about this ad campaign.
However, we did learn that Carl (Carolus) Linnaeus, the father of botany, was named for the linden tree! Here's a version of the story from Wikipedia:
Linnaeus was born in the countryside of Småland, in southern Sweden. His father was the first in his ancestry to adopt a permanent last name; prior to that, ancestors had used the patronymic naming system of Scandinavian countries. His father adopted the Latin-form name Linnaeus after a giant linden tree on the family homestead.The wiki entry is supported by Edmund Otis Hovey in the Annals of the New York Academy of Sciences (Volume 18) and by Edward Lee Greene in Carolus Linnaeus (both found via Google Books). Here's the link to Delta's environmental fact sheet.
