Hasta ahora se sabía poco sobre cuántos años dura, y eso pesa en cualquier plan que quiera contar con él para frenar el calentamiento.

Now, researchers from the Swedish University of Agricultural Sciences have found a new way to measure this, using wood from the 1960s that was affected by nuclear weapons testing. The paper is published in the journal Radiocarbon.","pubDate":"Tue, 20 Oct 2026 13:20:30 EDT","url":"https://phys.org/news/2026-10-carbon-wood-stability-biochar-soil.html"},"indexado":"2026-10-20T17:30:28.766Z"}}
