"Abstract. 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 of methane and 5x 10
16 grams of carbon dioxide. As much as 2 x 10
14 grams of molecular hydrogen may also be produced. Field measurements of methane emissions from two termite nests in Guatemala corroborated the laboratory results. The largest emissions should occur in tropical areas disturbed by human activities."

nine times more carbon dioxide to the atmosphere than all human activities combined. This huge carbon flux from soil, which is due to the natural respiration of soil microbes and plant roots, begs one of the central questions in climate change science."
