The abstract looks very interesting - if pretty technical - seems to me to be a valid perspective, ie relating climate forcing impact of burning a biomass fuel to the length of time before the emissions are taken up into plant matter again, in the harvest/grow cycle. And taking on board the realisties of actual land use systems.
Looks like a decent attempt to put a figure to the fact that CO2 is in the atmosphere temporarily after burning (or permanenetly if fuel not regrown). However as I'm not in an academic institution, no access to the paper, just the abstract, sadly.
