Diazotrophs are overlooked contributors to carbon and nitrogen export to the deep ocean

According to a new study published in The ISME journal, diazotrophs, a group of marine cyanobacteria capable of converting nitrogen gas (N2) from the atmosphere into nutrients for primary producers in the ocean, directly contribute to carbon export and sequestration on the seafloor. The findings...

Pioneering climate change research reveals long-term global carbon cycle impacts

Dr. Heather Ford of Queen Mary's School of Geography co-authored a new study in Nature Geoscience that uses a novel research model to demonstrate how past geologic periods can help us understand future climate changes. As research uncovers more about Earth's distant history, dating back...

Restaurant menu design could impact carbon footprint of dining

A study employing hypothetical restaurant menus suggests that climate-friendly default options and labels indicating the carbon footprint of each dish may influence diners' dish selections and the resulting environmental effects. Ann-Katrin Betz and colleagues at Julius-Maximilians-Universität Würzburg, Germany, present these findings in the open-access...

Novel particle detector used to study alternate path to carbon creation in stars

Washington University in St. Louis is part of a collaboration that has yielded new insight into one of the universe's primordial reactions that made all life on Earth possible. Carbon is generally thought by scientists to have formed inside the cores of stars. Now...

Hidden upwelling systems may be overlooked branches of ocean circulation

Upwelling and downwelling play an important role in transporting the heat, carbon, and nutrients that affect Earth's climate. Many studies have focused on these vertical motions in the ocean. This includes eastern boundary currents and the Southern Ocean. Previous research has suggested that western boundary...

Re-evaluating wetland carbon sink mitigation

University of Tasmania (UTAS), Nanjing Institute of Geography and Limnology of the Chinese Academy of Sciences (NIGLAS) and Universiti Malaysia Sabah (UMS) researchers have revealed that the current mitigation concepts for greenhouse gas emissions and measurements are not what they seem. The study was published...
