Although many Americans dutifully deposit their plastic trash into the appropriate bins each week, many of those materials, including flexible films, multilayer materials and a lot of colored plastics, are not recyclable using conventional mechanical recycling methods. In the end, only about 9 percent of plastic in the United States is ever reused, often in low-value products.
In the picturesque paradise of Maui, an ominous pattern of destruction has been unfolding. Devastating wildfires, once considered a rarity on the Hawaiian island, have become increasingly frequent and ferocious. As flames consume vast swaths of land this week, scientists and residents are grappling with the stark realization that these infernos are largely of our own making.
A team led by Virginia Tech researchers has developed a new method for upcycling plastics into high-value chemicals known as surfactants, which are used to create soap, detergent, and more.
Mountain ranges play a key role in global climate, altering weather and shaping the flora and fauna that inhabit their slopes and the valleys below.
Extreme weather events have dominated the news this summer, with reports on extensive wildfires in Canada; dangerous flooding in India, Japan, and the Eastern US; severe heat waves in Spain, China, the United States, and Mexico; and the hottest day ever recorded on Earth.
While some parts of the world suffer extreme heat and persistent drought, others are being flooded. Overall, continental water volumes vary so much over time that global sea levels fluctuate significantly too.
The funding supports phase two of “Project Pythia,” a collaborative effort to collect high-quality interactive learning tools for Python-based data analysis and visualization in the geosciences.
Paleoclimate evidence shows that around 1.1 million years ago, the southern European climate cooled significantly and likely caused an extinction of early humans on the continent, according to a new study led by UCL researchers.
An international research team details changes in DNA that researchers found are shared by humans and other mammals throughout history and are associated with life span and numerous other traits.
New research confirms fracking causes slow, small earthquakes or tremors, whose origin was previously a mystery to scientists. The tremors are produced by the same processes that could create large, damaging earthquakes.
New research shows that the hormone testosterone — which naturally triggers male electric fish to elongate the electric pulses they send out during the breeding season — also alters a system in the fish’s brain that enables the fish to ignore its own electric signals.
Hokkaido University researchers found that tiny nematode worm larvae surf electric fields to hitch rides on passing insects.
The rare moss Takakia has adapted over millions of years to a life at high altitudes.
A telecommunications fiber optic cable deployed offshore of Oliktok Point, Alaska recorded ambient seismic noise that can be used to finely track the formation and retreat of sea ice in the area, researchers report in The Seismic Record.
A research team from Wayne State University’s National Institutes of Health-funded Superfund Research Program, the Center for Leadership in Environmental Awareness and Research (CLEAR), recently published a paper that describes a new technique they developed that couples the Internet of Things sensor network with Edge Computing (IoTEC) to improve environmental monitoring. The paper, “IoT-based edge computing (IoTEC) for improved environmental monitoring,” was published recently in Sustainable Computing.
Despite broad scientific consensus that climate change has more serious consequences for some groups – particularly those already socially or economically disadvantaged – a large swath of people in the U.S. doesn’t see it that way.
Scientists at the Cornell Lab of Ornithology have developed a novel way to model whether the populations of more than 500 bird species are increasing or decreasing.
A study of 12 species of highly migratory fish predators—including sharks, tuna, and billfish such as marlin and swordfish—finds that most of them will encounter widespread losses of suitable habitat and redistribution from current habitats in the Northwest Atlantic Ocean (NWA) and the Gulf of Mexico (GOM) by 2100. These areas are among the fastest warming ocean regions and are projected to increase between 1-6°C (+1-10°F) by the end of the century, a sign of climate-driven changes in marine ecosystems.
An analysis of the hierarchy of tipping points suggests that during the last 66 million years two events set the scene for further climate tipping and for the evolution of the climate system in particular.
