Dr. David Olefeldt, one of the authors of “Climate change and the permafrost carbon feedback” published last week in the online journal Nature.com, says we are still in the driver's seat. The paper, compiled by a network of international researchers, synthesizes the existing scientific knowledge on possible impacts ongoing permafrost melt in the Arctic could have on climate change.
According to a University of Alberta study, old drywall can be used to add nutrients to “dead” soils. The team which put the study together was headed by M. Anne Naeth, who works with the U of A’s department of renewable resources. They found that used drywall can be full of decomposable material and useful nutrients, which “would be a good compost additive for use on reclaimed land sites,” a story on the U of A’s website said.
ALES researchers will soon be able to start examining the effects of the three different harvesting techniques used to log near the Star Creek headwaters area and compare them to the impacts of the 2003 Lost Creek wildfire. Logging is almost complete and signals the beginning of the second phase of the Southern Rockies Watershed Project, which is internationally recognized as the first major effort globally to provide a comprehensive assessment of forest disturbance impacts on water from source to tap.
