New Research Shows That Common Coolants Contribute to Ozone Depletion

According to new research from NASA, chemical coolants known as hydrofluorocarbons that are found in refrigerators and in home and automobile air conditioners, contribute to ozone depletion by a small but measurable amount. The paper, published October 22 in Geophysical Research Letters, a journal of the American Geophysical Union, is based on the results of […]

NASA Studying Never Before Seen El Niño Event

NASA scientists continue to monitor and study this year’s El Niño, which appears likely to equal the event of 1997-98 – the strongest El Niño on record. Every two to seven years, an unusually warm pool of water — sometimes two to three degrees Celsius higher than normal – develops across the eastern tropical Pacific […]

New Study Reveals Earth’s Inner Core was Formed 1 – 1.5 Billion Years Ago

New data from the University of Liverpool reveals that the Earth’s inner core was formed 1 – 1.5 billion years ago as it “froze” from the surrounding molten iron outer core. The inner core is Earth’s deepest layer. It is a ball of solid iron just larger than Pluto which is surrounded by a liquid […]

NASA Measures a Pulsating Aurora

Using satellites, a ground-based array of all-sky cameras, and some spectacular aurora borealis, a team of scientists has uncovered evidence for an unexpected role that electrons have in creating the dancing auroras. Though humans have been seeing auroras for thousands of years, we have only recently begun to understand what causes them. In this study, […]

Scientists Solve the Problem of Sea Ice Thickness Distribution

Using molecular concepts and treating the ice floes of the frozen seas like colliding molecules in a fluid or gas, researchers at Yale University have answered a 40-year-old question about Arctic ice thickness. Although today’s highly precise satellites do a fine job of measuring the area of sea ice, measuring the volume has always been […]

Scientists Measure Meltwater on the Surface of the Greenland Ice Sheet

Scientists gather field data on the Greenland Ice Sheet to help verify climate models that are used to estimate future sea level rise and to incorporate the measurements into computer models that will create a simulation of the melt water runoff processes operating on the ice sheet. On Greenland’s ice sheet, a vast icy landscape […]

New Research Shows Phytoplankton Are Extremely Sensitive to Changing Levels of Desert Dust

A newly published study shows that phytoplankton are extremely sensitive to changing levels of desert dust, revealing that the intensity of desert storms may affect the whole ocean ecosystem. Each spring, powerful dust storms in the deserts of Mongolia and northern China send thick clouds of particles into the atmosphere. Eastward winds sweep these particles […]

Optical Image of Jakobshavn Glacier in Western Greenland Shows Massive Calving Event

New ESA satellite images show that the fastest moving glacier in the world (the Jakobshavn glacier) shed a massive chunk of ice measuring around 12.5 square kilometers – one of the most significant calving events on record. Radar images from Sentinel-1A captured the Jakobshavn glacier in western Greenland before and after the event, which took […]
