Receding glacier causes Canadian river to vanish in four days

For the latter, I think the research and other work for using Paulownia trees for carbon sequestration qualifies. I do seem to recall that there was some attempt to further cultivate it to be more suitable for that purpose.

Thanks! I hadnt heard of Paulownia before. 3-10x more sequestration than the average tree: http://paulowniabg.info/?page_id=56

One challenge with plant-based sequestration is that the carbon is released when the tree dies/decomposes. I wonder how planting more trees will balance out at the decade-century scale.

Cut them down when mature and use them as building material.

Wow cool, at first I said "but the CO2 gets released when the building burns down", so I looked into it. Apparently wood has a ton of benefits, basically it doesn't release much of the CO2 if it just sits there (http://www.awc.org/pdf/education/gb/ReThinkMag-GB500A-Evalua...). And it takes far less energy to grow a tree than the respective amount of concrete/other building materials (http://www.treehugger.com/green-architecture/new-study-confi...). So wood->building materials is a great option. Right on!
