        Chris, this entry caught my eye: Solving climate change by abusing
        thermodynamic scaling laws [1] In a previous section, I provided a
        rough number of 6800 kg. biomass harvested per hectare each year. To
        entirely offset global emissions of carbon dioxide, we would need
        approximately 40 billion tons sequestered per year; at 6 metric tons
        per acre, this implies 6 billion hectares of arable land.
        Unfortunately, we only have 1.4 billion hectares.
        
        Is the 1.4 billion constrained by zones that have summers good for
        growth and winters that can freeze water?
        
          I assume that the hemisphere is of sufficient size to accommodate the
        harvest of one township (approx. 9300 hectares)
        
        Ahh, townships have closely packed houses, schools, pools, etc - not
        harvests (well, we do harvest small patches of our township land - but
        that's more a large gardening scale thing).
        
        Here, in one shire of a grain growing region, the central township area
        is 18 square kilometres (1,800 hectares) while the townsite and
        surrounding shire district area is ~2,100 square kilometres (210,000
        hectares)(~800 sq mi) with an average single farm size of ~ 4,500
        hectares (One local farm family I know of own that much land about
        their house, that much land again elsewhere, and farm much more land
        than that total they own via leasing and share farming - the 9,300
        hectares quoted is more or less mean farming family harvest)
        
        Not much scope here for bulk freezing biomass in winter though, there's
        rarely ice overnight and never snow here historically.
        
        Still, details aside the roll your own biomass permafrost is an
        interesting take.

          Thanks for taking a look at that article! In short, you're right on
          the first item; only a fraction of that total arable land actually
          experiences subfreezing winter temperatures.
          
          Given your word choice, I suspect you hail from Britain or a
          commonwealth country and your (appropriate) definition of township
          differs from mine. I should have defined it as "survey township"
          which is a USA term for a grouping of land parcels six miles tall by
          six miles wide. Again, the number presented is a ballpark estimate,
          as though we may not have as many nice villages and hedgerows in the
          Dakotas and other Plains states, we similarly do not farm every
          single literal acre--though many act as if we should, animals and
          people be damned.
