A couple of days ago we received a Physorg.com article via Alan Siddons, Even soil feels the heat: Soils release more carbon dioxide as globe warms, [LINK], this was a summary article for a report that appeared in Nature (Bond-Lamberty and Thomson, 2010. Temperature-associated increases in the global soil respiration record, Nature March 25, 2009).
Alan included the following comments.
More evidence that a climbing CO2 rate is the result of warming, not the cause. There are two other ramifications as I see it.
1. Results like this mean that the anthropogenic fraction must be readjusted. Is man’s annual contribution 4%? 3%? Less?
2. This latest natural emission estimate shows that previous source/sink models have been inadequate, as usual. – AS
The following then appeared in the comments section of CR by Ben Bond-Lamberty and Allison Thompson, the authors of the said article.
