Termites may emit large quantities of methane, carbon dioxide, and molecular hydrogen into the atmosphere. Global annual emissions calculated from laboratory measurements could reach 1.5 x 10(14) grams methane 5 10(16) dioxide. As much as 2 also be produced. Field two termite nests in Guatemala corroborated results. The largest should occur tropical areas disturbed by human activities.
