For example, there are extensive areas of Siberian permafrost that are essentially frozen soil (with lots of not-very-degraded mammoth dung as a major component).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8524070301101240472.post-23636885949517854252007-09-28T19:08:00.000-07:002007-09-28T19:08:00.000-07:00Well, it's a hard call.

This seems to be the operative statemnt from the abstract.<BR/><BR/>"Our results suggest that the loss of surface permafrost in peatlands increases net carbon storage as peat, though in terms of radiative forcing, increased CH4 emissions to the atmosphere will partially or even completely offset this enhanced peatland carbon sink for at least 70 years following permafrost degradation."<BR/><BR/>Not sure what this means in terms of GWP, but it's good news compared to the previous conventional wisdom, where it's all chalked up to positive feedback.Michael Tobishttps://www.blogger.com/profile/08229460438349093944noreply@blogger.comtag:blogger.com,1999:blog-8524070301101240472.post-11783647868240552822007-09-28T16:41:00.000-07:002007-09-28T16:41:00.000-07:00So, basically, Park has got it 100% wrong?Is this ...So, basically, Park has got it 100% wrong?<BR/>Is this normal for BP?Unknownhttps://www.blogger.com/profile/16986271841074352598noreply@blogger.com
