Ribbed mussels can remove nitrogen and other excess nutrients from an urban estuary and could help improve water quality in other urban and coastal locations, according to a study in New York City’s Bronx River. The findings, published in Environmental Science and Technology, are part of long-term efforts to improve water quality in the Bronx River Estuary.

The “social cost of carbon” — an influential figure used by policymakers to weigh the value of efforts that reduce greenhouse gas emissions — is outdated and underestimated. Updated estimates focused on the agricultural sector alone more than double the social cost of carbon, according to analysis from the University of California, Davis, and Purdue University.

El "costo social del carbono", una figura influyente utilizada por los políticos para ponderar el valor de los esfuerzos que reducen las emisiones de gases de efecto invernadero, está desactualizado y subestimado. Las estimaciones actualizadas se centraron solo en el sector agrícola, más del doble del costo social del carbono, de acuerdo con el análisis de la Universidad de California, Davis y la Universidad de Purdue.

A team of university and government scientists, selected by an expert review panel convened by the Mississippi-Alabama Sea Grant Consortium, will conduct an independent study to estimate the number of red snapper in the U.S. waters of the Gulf of Mexico.

“American communities across the Gulf of Mexico depend on their access to, as well as the long term sustainability of, red snapper,” said Secretary of Commerce Wilbur Ross. “I look forward to the insights this project will provide as we study and manage this valuable resource.”

A major study looking at changes in where UK birds have been found over the past 40 years has validated the latest climate change models being used to forecast impacts on birds and other animals.
