I looked at that Brian thanks

The only reference I have found is
http://www.carnegieinstitution.org/news_releases/news_0512_05.html

Did you read the tenor of that one Angus?

However this announcement was in December 2005. I would imagine there
must be some update as it was featured in newspapers a few days ago.


which suggests your suspicions are correct. About a year ago, however,
I recall some concern being expressed by German scientists about trees
emitting significant quantities of methane, so that may have a bearing,
too.


Details of Dr Keppler<s research were published in a number of
newspapers and for the benefit of readers of this letter the links are
shown below.

Did you read the comments about the correction/clarification placed in the
Guardian.

My own observation is that growing trees have to store up carbon. If they
emit methane it comes from CO2. Methane is a powerful greenhouse gas more
so than CO2.

The writer makes the main point that planting of trees has a complex
relationship with global warming.

But this is not the only research that has questioned the value of trees
to combat climate change.

This was highlighted in a BBC News item and the link is shown below.

Highly complex then!
