A researcher at Switzerland's University of Zurich has combined 25 years worth of satellite imagery to show the complex behavior of glaciers in a single second. The effort made use of data collected by NASA's Landsat satellites, focusing on the Karakoram mountain range in Asia.
A new study from the University of Victoria has, for the first time, estimated the total volume of groundwater present on the Earth. The results show that we're using up the water supply quicker than it can be naturally replaced, while future research will seek to determine exactly how long it will be until modern groundwater runs dry.
NASA has analyzed 14 years worth of data collected by its Thermosphere, Inonosphere, Mesosphere Energetics and Dynamics (TIMED) satellite, revealing a surprisingly fast increase in carbon dioxide levels in the upper atmosphere. The stats also reveal that the gas is more localized to the Northern Hemisphere than predicted by climate models.
Carbon nanofibers hold tremendous potential. They may one day be put to use in tougher bulletproof vests, artificial muscles or rebuilding damaged hearts, just to name a few possibilities. But could the greatest gift these little wonders offer humanity be not what they bring into the world but what they take out of it? Scientists have developed a technique that could take the mounting carbon dioxide in our atmosphere and transform it into carbon nanofibers, resulting in raw materials for use in anything from sports gear to commercial airliners.
Three French students will travel from Bangkok, Thailand to Toulouse, France on an electric tuk-tuk in an effort to demonstrate that electric power will be sufficient for our future mobility needs. They plan to cover 20,000 km (12,427 mi) through 16 countries in 120 days on their modified three wheeler relying on two giant batteries, a solar panel and the generosity of strangers.
Over the last few years, many possible explanations have been bandied about for the so-called pause in climate change, a plateau in global surface air temperatures that is out of step with rising greenhouse gas concentrations. But now an international research effort is laying responsibility at the feet of volcanic eruptions, whose particles it has found reflect twice as much solar radiation as previously believed, serving to temporarily cool the planet in the face of rising CO2 emissions.
An international team of scientists has found that retreating sea ice between the Atlantic and Arctic Oceans is linked to weakened air-sea heat exchange in the region. This, it warns, could result in a cooler climate in western Europe and an altered or slower Atlantic Meridional Overturning Circulation (AMOC), which would have knock-on effects for the Gulf Stream and consequently for the atmosphere.
NASA has released a dataset setting out how rainfall and temperature patterns are likely to change in the coming decades. The data covers 21 climate models, mapping how our environment could change due to growing concentrations of greenhouse gases in the atmosphere.
Scientific curiosity around how air interacts with the ocean in the event of powerful storms has inspired a number of wind-emulating facilities around the world, from a high-speed wind-wave tank at Kyoto University to the Hydrodynamics Laboratory at Imperial College London. But just as hurricane season kicks off in the US, a team at the University of Miami is looking to step things up a notch. A freshly built indoor tank designed to study category five storms is now open for business, and as the only one of its kind in the world, is hoped to offer a new understanding of these destructive superstorms.
A team of researchers from France, Nepal and the Netherlands has worked to produce a new model to predict the future changes in glaciers in the Everest region of the Himalayas. While the study, which was conducted by the European Geosciences Union (EGU), only represents an initial approximation of ice loss in the region, the model suggests that dramatic changes may be ahead.
