More natural processes of cloud brightening or enhanced weathering are less likely to raise objections, but the public react best to creating biochar (making
charcoal from vegetation to lock in CO2) or capturing carbon directly from the air.»
Reconstructed mass balance yielded accumulation and ablation each of ~ 3 km3 / yr, with glacial movement near the equilibrium line altitude dominated by basal sliding.Pollen and
charcoal records
from three lakes in northern Yellowstone provide information on the postglacial
vegetation and fire history.
