Persistent methane emissions from sectors such as agriculture and growing debates over the credibility of carbon offsets are creating new challenges for governments and companies pursuing net-zero commitments. New research suggests temporary carbon storage may have a scientifically valid role in helping support climate goals, if used in the right way.
Based on a 20-year field nitrogen addition experiment, this study demonstrates that long-term high nitrogen deposition does not reduce belowground carbon allocation in tropical forest plants; rather, it induces a physiological adaptation—upregulation of root exudation—to actively mobilize soil phosphorus, thereby sustaining productivity and offering a key mechanistic explanation for the persistence of tropical forest carbon sinks under chronic nitrogen enrichment.
Every summer for nearly three decades, a team at Michigan State University has made their way to Manistee National Forest to look for new trees that have sprouted. At less than a year old, the youngest seedlings aren’t much taller than their toes. But now, the team’s annual counts of 10 tree species are starting to reveal clues to what the region’s forests might look like in the 20, 40 or 100 years to come.
Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in PNAS demonstrates that ice actively speeds up the breakdown of iron minerals and may release more iron than current environmental models account for. This is crucial for predicting how nutrient cycles, carbon storage, and water quality will change in polar and mountain regions as the planet warms.
Lakes play a vital filtering role in the ecosystem: they remove excess nitrogen from the water. An international research team led by the University of Basel and Eawag has now shown that climate change could weaken this natural purification process. This would have consequences extending all the way to coastal marine ecosystems.
Scientists from the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT), together with Hacienda San José (HSJ) in the department of Vichada, developed a pioneering methodology to estimate greenhouse gas emissions associated with bovine genetic resources—a component that had so far remained invisible in livestock carbon footprint analyses.
The study, published in the prestigious journal The International Journal of Life Cycle Assessment, demonstrates that the Short-Cycle Nelore breed used at HSJ emits up to 17% fewer greenhouse gases per kilogram of live weight than conventional Brahman cattle, due to its accelerated growth and reproductive performance.
This finding complements the study published in 2022 by the same team, which concluded that the integrated management of improved pastures in tropical savannas can offset up to three times the emissions generated by cattle.
