Resumen:
A new global synthesis and biomization of long (>40 kyr) pollen-data
records is presented and used with simulations from the HadCM3 and
FAMOUS climate models and the BIOME4 vegetation model to analyse the
dynamics of the global terrestrial biosphere and carbon storage over the
last glacial-interglacial cycle. Simulated biome distributions using
BIOME4 driven by HadCM3 and FAMOUS at the global scale over time
generally agree well with those inferred from pollen data. Global
average areas of grassland and dry shrubland, desert, and tundra biomes
show large-scale increases during the Last Glacial Maximum, between ca.
64 and 74 ka BP and cool substages of Marine Isotope Stage 5, at the
expense of the tropical forest, warm-temperate forest, and temperate
forest biomes. These changes are reflected in BIOME4 simulations of
global net primary productivity, showing good agreement between the two
models. Such changes are likely to affect terrestrial carbon storage,
which in turn influences the stable carbon isotopic composition of
seawater as terrestrial carbon is depleted in C-13.
