Thank you for this article--it's important to acknowledge the role that non-tropical forests play in carbon sequestration. Our organization is working on tree planting and environmental education programs in the Republic of Armenia, and we appreciate new research such as this that helps the public and even foresters to better understand these important ecosystem dynamics.
Good information here. Over all the web site is well constructed. I would, however, suggest you change the orange(?) to some other color. The orange is hard to read.
did anyone hear the audio book of a new earth yet or the book it is on oprah web page. i am taking her class every monday night and they were also talking about the trees and the forrest too and stuff and this remind me how life is so precius to all of uf because trees breathe just like we do and they die just like we do if we arent taking care of us. i might write a poem a song about the universe on how the trees and everything is just like us too. do you people see it too
Nice article. Here are some additional resources explaining more about how climate change is likely to affect Pacific Northwest forests as well as how forest conservation and restoration (including sensible changes to this project) may help mitigate climate change. The report also helps debunk some of the flawed arguments used by logging advocates. http://tinyurl.com/2n96m5 http://www.slideshare.net/guestf419ee/debunking-myths-about-forest-carbo...
I wonder if there is any validation of the statement thta deforestation ,especially in tropicel areas, accounts for as much as 20 % of the greenhouse hases now being emitted. jjjburton@verizon.net
Interesting article. Does this mean that "closed loop" strategies to utililze woody biomass for energy and have new growth compensate for the carbon removal of that woody biomass is not valid?
I would be interested in an analysis that takes a look at the rate of CO2 sequestration by forest age classes and compare it to their carbon emissions after harvest after factoring in carbon sequestration of typical forest products over their life cycle, to see what the net effect is.
Can this data be used to support maintenance and celebration of old healthy trees in cities? In our cities we strive for 40% canopy some day.... but individual trees are removed with impunity when a limb drops or a crack appears.... yet with maintenance the tree life can double or triple.. Can we use this carbon data to support advocacy for old trees being kept on city streets? please email to: guffguelph@gmail.com
I feel trees are crutical to our environment and that William Randolph Hurst did an awful crime against them. He bought acres and acres of trees to create more money for himself by processing the trees to paper. Then his scientist told him the best thing to make paper in nature was not a tree, but the marijuana plant. So this poweful man got a law passed in three days that outlawed the marijuana plant so he could use his trees to make paper. It's been that way since the 1930's. I feel it is time to turn this back around and legalize the marijuana plant for paper and save trees. I hear marijuana also makes fuel for vehicles. Chris Conrad ran for Governor of Kentucky and used hemp fuel in his car from one end of the state to the other. He did not win the election, but he proved that his fuel worked. And if your worried about people smoking it, Marijuana is safer to use than anything legal as in alcohol and tobacco. A cigarette was the most addictive drug I've ever done in my whole life, (I'm over 50). So please help save the planet and legalize marijuana for paper and fuel.

I was forced to have my beautiful fern pine cut down yesterday and I cried my eyes out. The HOA here gave me reason after reason when I would squash their purpose another reason would come up. The final reason had to do with roots & plumbing lines under the back porch. This tree gave me immeasurable pleasure. The birds, the screening, the shade, etc. My 4 year sobbed uncontrollably as it was being cut saying 'I want it to stay - it's a living thing" - My tree was a giving tree and I appreciate what this article says as it is what I believed. The 'garden committee' is not a very eco friendly garden committee for they are the one behind the demise of this tree. Long live trees.
Hi first I want to tell you that I really liked this article. And second I have a request to make; I just wrote this short story to post on my personal blog(just for fun)and I fell in love with the image of this tree in the top of the article, so I would like to have your permission to use it to illustrate my short story. My e-mail is danielle_oh_shin@yahoo.com, thanks a lot in advance.
This is a great article, and extremely beneficial to all of those who read it. I work as a Chicago freelance web designer and I have moved all of my billing and payment processing to paperless methods. I keep up on emails and web applications it order to help the environment.
If we all do our part, or even attempt to help, we can make a huge difference.
hi reading this has been really informative, i am about to start working with schools in the uk to learn and act on co2 emissions, to help them visualise our relationship with the world around us i wanted to find out how many trees/plants it takes to keep each individual breathing? i know this is a bit simplistic but i need a way to make this accessable, if anyone can help me find this out it would be greatly apeciated.
best wishes

In the carbon cycle, it's not just about the individual tree-the entire forest plays a role. Leaves take in carbon dioxide, converting it to sugar, which is carbon-based. Some of the sugar is used immediately for energy, converted back to CO2, and released into the atmosphere. The rest is stored in living wood or dead matter, such as fallen leaves and branches. Old-growth forests, in particular, store vast amounts of carbon while continuing to absorb CO2. More
