A key finding of the study, published in Science Advances, is that coastal marshes experience tipping points, where a small increase in the rate of sea-level rise leads to widespread submergence.
High-intensity fires can destroy marshy peatlands and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new Duke University study finds low-severity fires spark the opposite outcome. By creating a decay-inhibiting crust on clumps of moist soil particles within the peatland, the smaller surface fires help protect the stored carbon and enhance peatlands' long-term storage of it, even during times of extreme drought.
Why do carbon dioxide levels in the atmosphere wax and wane in conjunction with the warm and cold periods of Earth's past? Scientists have been trying to answer this question for many years, and thanks to chemical clues left in sediment cores extracted from deep in the ocean floor, they are starting to put together the pieces of that puzzle.
Over 80% of the world's flowering plants must reproduce in order to produce new flowers, according to the US Forest Service. This process involves the transfer of pollen between plants by wind, water or insects called pollinators -- including bumblebees. In a new study, researchers at the University of Missouri discovered spiny pollen -- from a native wild dandelion species in the southern Rocky Mountains -- has evolved to attach to traveling bumblebees.
The world's growing population will necessitate a 30-70% increase in food production over the next 3 decades. If we are to succeed, it will require a complete overhaul of the way we produce food. Researchers from the University of Copenhagen, among others, have now created an overview of solutions that include a number of new technologies that can collectively address this global challenge.
Research shows Buchan Caves to be about 3.5 million years old and that Victoria's East Gippsland has remained tectonically active for long times, even into the present-day, which is why residents occasionally report earthquakes. Basically, the uplifting Southern Alps in New Zealand have made stress and strain on the Australian tectonic plate, stress that is then expressed as earthquakes and rising landscapes in Victoria. It's rather amazing that the caves recorded this geological signal all the way from NZ.
For the first time, seismologists can characterize signals as a result of some industrial human activity on a continent-wide scale using cloud computing.
By studying the chemical elements on Mars today -- including carbon and oxygen -- scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life.
In a new study, researchers from the University of Copenhagen have demonstrated that penguins in Antarctica emit copious amounts of nitrous oxide via their feces. So much so, that the researchers went "cuckoo" from being surrounded by penguin poop.
Food production has always shaped the lives of humans and the surface of the Earth. Today, with almost 40% of all land on Earth used for food production, the food system massively impacts climate and environment. In a new study published in the journal Nature Food, an international team of researchers has now assessed and categorized key innovations with a potential to transform the food system.
