"Ponds: Surprising Sources of Greenhouse Gas Emissions"

Two studies by Cornell researchers have found that ponds, both natural and human-made, may be net emitters of greenhouse gases, releasing more than they store. The studies highlight the significant impact of ponds on the global greenhouse gas budget, an area that is not well understood. The researchers found that ponds sequester carbon but also release methane, a potent greenhouse gas. The findings suggest that ponds contribute more to global methane emissions than previously estimated and that scientists are underestimating carbon sequestration in ponds and lakes. The studies also indicate the possibility of reducing methane emissions from ponds through the use of bubblers or underwater circulators.
