CLIMATE CHANGE SCIENCE: CARBON CYCLE
Software Availability: Global Carbon Cycling ModelGLOCO Version
2.0 for Macintoshä and Windowsä . Contact Elec. Power Software
Ctr., 1930 Hi Line Dr., Dallas TX 75207 (800 763 3772).
Version 2.0 maintains the GLOCO model's graphical interface, but has
extensively revised code and algorithms that reflect the latest scientific
understanding. Changes include new photosynthesis, respiration and carbon
algorithms in the terrestrial ecosystem module; separate treatment of
agricultural activity for each biome; input of nitrogen deposition scenarios
independent of CO2 emissions; recalibration based on the historical record from
1700 through 1990; and estimates of historical anthropogenic emissions and land
use changes from 1700 to the present.
Understanding Relationships Among Forest Products, Resource
Renewability and the Global Carbon Cycle, A. Lucier, 1995. Contact Alan
Lucier, NCASI, POB 13318, Res. Triangle Pk. NC 27708 ( fax: 919 558 1998).
Reprint of a paper presented at a technical session on life-cycle analysis
and environmental marketing at a Sep. meeting of the Forest Products Research
Society. Analyses of forest-sector policy options for reducing net CO2 emissions
have focused primarily on increasing carbon storage in forests. Inadequate
attention has been given to possible secondary effects of policy options on
timber supplies, private land use decisions, carbon storage in forest products,
and competition between forest products and substitute materials with different
life-cycle energy profiles.
Estimating Woody Biomass in Sub-Sarahan Africa, A.C. Millington,
R.W. Critchley et al, Eds., 208 pp., 1994, $24.95. Order from World Bank Book
Store, 1818 H St. NW, Washington DC 20433 (tel: 202 473 2941; e-mail:

The first attempt to analyze the stock and sustainable yield of woody
biomass in the subcontinent. Found that Africa may have nearly 70 billion tons
of carbon stored in trees, a much larger amount that previously suspected. A
surprising amount of wood is growing outside tropical rainforests on farms in
the arid and semiarid regions. This discovery could help explain the missing
carbon sink. (See New Scientist, p. 8, June 11, 1994.)
