Additional sequestration articles

Below are a couple of articles that look into similar issues as those addressed in our Beedlow reading for the September 21 lecture.

NOTE: you will need to be logged into the UMich network through CTools, Wolverine Access, etc. in order to be able to connect to these PDFs.

The first investigates the impact of applying additional N to a deciduous forest and its effect on photosynthetic capacity.

The second approaches the issue by looking at five different strategies for carbon sequestration, including afforestation and shifts in agriculture, as well as the addition of manure or straw to the soil. While this article addresses some of the same issues as Beedlow, it comes to slightly different conclusions with regard to its sequestration projections.

There are a lot more issues about plants' responses to the rising carbon than that. I don't know how many are right, but there might be some ideas. For instance, that plants will produce more carbs with fewer innate nutrients to supplement them, which is not good for the secondary consumers, and that the carbon makes the oceans too acidic for diatoms. The idea is put about in the following comic, although I can't seem to find the news link posted in it yet. I have a list for science news under climate change if you want to help me look. I'll put them there:
Also, this would probably be the perfect time to introduce the Climate Denial Crock of the Week videos!

And, just to add to the links regarding carbon sequestration long after the fact; here's an article that came out Dec 11th about the possibility of retro-fitting buildings with green roofs to sequester carbon out of the atmosphere (in addition to all of the other good things they do too), with a special mention of Detroit, MI.


The amount of vegetation on a green roof clearly doesn't compare to that of an old-growth forest, and won't be a suitable substitute for carbon loss from tropical deforestation. But, in comparison to the current level of carbon that can be sequestered in the conventional roofs of urbanized areas…
