Excerpt from Washington Post article:<br>
<br>
"European forests have failed to realize a net [carbon dioxide]
removal from the atmosphere, and this is due to the fact that humans
extracted wood from unmanaged forests by bringing these forests under
management," said the study's lead author Kim Naudts, a
researcher with the University of Versailles' Climate and
Environmental Sciences Laboratory at the time the work was
conducted.<br>
<br>
"Even a well-managed forest today stores less carbon than its
natural counterparts in 1750," Naudts said.<br>
<br>
Additionally, the researchers found that replacing broadleaved forests
with conifers had another unintended warming effect. Conifer leaves
tend to be darker than those of broadleaved trees, Naudts pointed out,
so they allow more sunlight to be absorbed.</font><br>

<div><font face="Geneva" size="-1">And, Naudts added, "the other
effect is that they are more conservative with water, which leads to
less evapotranspiration, and to drier air." Evapotranspiration is
the process by which water evaporates out of a tree's leaves into the
atmosphere. The resulting drier air also contributed to a warming
effect.</font><br>
