U.S. wastewater treatment plants emit the equivalent of 47 million metric tons of CO2 each year. Methane and nitrous oxide emissions exceed previous estimates by 41%. Emissions can be slashed by tackling methane leaks, capturing nitrogen.
The Pacific Marine Science Alliance Society (PMSA) has announced a three-year agreement with the Marine Environmental Observation, Prediction and Response Network (MEOPAR) designed to strengthen national ocean research collaboration across Canada’s three coasts.
UBC is one of five member universities of the PMSA, which owns and operates the Bamfield Marine Sciences Centre, and works to advance marine and coastal research, education and sustainability.
The new partnership, backed by $300,000 in funding from PMSA and MEOPAR, will help researchers better collaborate at regional, national and international levels to address crucial research challenges, including climate resilience, marine hazard prediction and sustainable ocean resource use. The collaboration will also prioritize Indigenous-led stewardship, student mobility and new international research partnerships.
Tiny ocean organisms living in oxygen-poor waters turn nutrients into nitrous oxide—a greenhouse gas far more powerful than carbon dioxide—via complex chemical pathways.
Penn’s Xin Sun and collaborators identified the how and why behind these chemical reactions, showing that microbial competition, not just chemistry, determines how much N₂O is produced.
Their findings pave the way for more reliable climate models, making global greenhouse gas estimates more effective, predictable, and easier to understand in response to natural and man-made climate change.
A University of Sydney student has developed a completely new way to peer inside coral fossils to recover lost records of past climate change. The method opens the door to recovering climate information from coral samples once written off as too altered to be useful
The increasing mismatch between hours of daylight and temperature could spell trouble for animals that thrive by relying on seasonal cues to prepare their bodies for winter, according to new research from Case Western Reserve University.
