New work by Dr Michael Kelleher and Prof James Screen from the University of Exeter find evidence that sea ice change is both a driver of and a response to atmospheric variability.
Geologists exploring volcanic rocks on Scotland's Isle of Skye found something out-of-this-world instead: ejecta from a previously unknown, 60 million-year-old meteorite impact. The discovery, the first meteorite impact described within the British Paleogene Igneous Province (BPIP), opens questions about the impact and its possible connection to Paleogene volcanic activity across the North Atlantic.
Instability of the East Antarctic Ice Sheet signals increased risk of rising sea levels.
It may take until the 2060s to know how much the sea level will rise by the end of this century, according to a new Rutgers University-New Brunswick-led analysis. The study is the first to link global and local sea-level rise projections with simulations of two major mechanisms by which climate change can affect the vast Antarctic ice sheet.
Geologists use zircon mineral grains to reconstruct what the Earth and its landscapes looked like in ancient times. A new study led by The University of Texas at Austin Jackson School of Geosciences suggests that scientists may be able to better leverage zircon data to understand how landscapes have evolved over time by considering a suite of factors that can skew zircon geochronologic data and interpretation of the origin of sediments.
Men are more likely to go missing on a night out and be found dead in December than at any other time of the year, according to a sobering new report from the University of Portsmouth.
Western North Pacific anomalous anticyclone (WNPAC, or referred to as Philippine Sea anomalous anticyclone) is the most important anomalous circulation pattern connecting El Niño and East Asian-western North Pacific monsoon. WNPAC persists from the El Niño mature winter to the following summer and thus is one of the most long-lasting anomalous circulation patterns over the entire tropical climate system. A new mechanism was proposed to explain the maintenance of the WNPAC, which was named as 'anomalous moist enthalpy advection mechanism.'
Few people draw a parallel between bumblebees and travelling salesmen but that's what comes after months of tracking the flight paths of the foraging pollinators as they refine their routes around multiple destinations and, in the process, provide insights into analogous problems in logistics and robotics and into how land might be used more efficiently.
Why do the Andes exist? Why is it not a place of lowlands or narrow seas? Wouter Schellart, a geophysicist at the Vrije Universiteit Amsterdam, has been pondering these questions for more than a decade. Now, he has found the answers using an advanced computer model. 'It's a matter of enormous size, longevity and great depth,' he said. 'These aspects made the Andes the longest and second highest mountain belt in the world.'
The loss of forests in Africa in the past century is substantially less than previously estimated, an analysis of historical records and paleontology evidence by Yale researchers shows.
