I heard a report about this study recently,
http://www.sciam.com/article.cfm?chanID=sa003&articleID=DCA231BA-E7F2-99DF-3105874539B83ECB&ref=rss
snip: "A new study, however, published in /Proceedings of the National
Academy of Sciences/ reports that forests' other climatic effects can
cancel out their carbon cleaning advantage in some parts of the world.
Using a three-dimensional climate model, the research team mimicked full
global deforestation and also studied the effects of clear-cutting in
different regions of latitude, such as the tropics and boreal zones.
Apparently, these natural carbon sinks only do their job effectively in
tropical regions; in other areas, they have either no impact or actually
contribute to warming the planet. In fact, according to this model, by
the year 2100, if all the forests were cut and left to rot, the annual
global mean temperature would /decrease/ by more than 0.5 degree
Fahrenheit."
On the other hand,
"I like trees because they seem more resigned to the way they have to
live than other things do." —/Willa Cather/
and there is nothing (well, nearly nothing) I will miss more when I die
than biking along a smooth tree canopied street in August at supper time.
