Intact Mangroves Show Greater Carbon Preservation and Distinct Sediment Chemistry
A multidisciplinary team of researchers from the Philippines and Japan found that older intact mangrove forests in Aklan had higher sediment organic carbon content and a chemical composition distinct from that of younger restored sites. The team included Dr. Rene Rollon of the Institute of Environmental Science and Meteorology, University of the Philippines Diliman. The researchers combined vegetation surveys, sediment…

How warming may increase rainfall from Philippine typhoons
A new study by IESM faculty members Rafaela Jane Delfino and Gerry Bagtasa, together with Pier Luigi Vidale and Kevin Hodges of the University of Reading and the National Centre for Atmospheric Science, examined how a warmer climate may affect rainfall from Typhoons Haiyan, Bopha, and Mangkhut. Using high-resolution weather models, the researchers simulated the three storms under pre-industrial, present-day,…
