Resilient form of plant carbon gives new meaning to term 'older than dirt'
A particularly resilient carbon from the first plants to regrow after the last ice age -- and that same type of carbon from all the plants since -- appears to have accumulated for 11,000 years in the forests of British Columbia. Modelers of carbon cycles, who've assumed that this type of carbon remains in the soils only 1,000 to 10,000 years before it returns to the atmosphere as carbon dioxide, may need to revise their thinking.
