Van Allen Probes Reveal an Impenetrable Barrier in Space

December 1, 2014


NASA Spots an Impenetrable Barrier in Space

Using NASA’s Van Allen Probes, new research reveals that the Van Allen radiation belts contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth. This movie shows how particles move through Earth’s radiation belts, the large donuts around Earth. The sphere in the middle shows a cloud of colder material […]

Yarlung Tsangpo Valley close to the Tsangpo Gorge

The new discovery a deep canyon buried along the Yarlung Tsangpo River in south Tibet effectively rules out a popular model used to explain how the massive and picturesque gorges of the Himalayas became so steep, so fast. A team of researchers from Caltech and the China Earthquake Administration has discovered an ancient, deep canyon […]

2014 – The Highest Global Mean Sea Surface Temperatures Ever Recorded

November 14, 2014


New Research Shows Warmest Oceans Ever

New data reveal the highest global mean sea surface temperatures ever recorded, indicating that the 14-year-long pause in ocean warming has come to an end. “This summer has seen the highest global mean sea surface temperatures ever recorded since their systematic measuring started. Temperatures even exceed those of the record-breaking 1998 El Niño year,” says […]

MIT Reveals Missing Piece of the Climate Puzzle

In a newly published study, MIT researchers show that a canonical view of global warming tells only half the story and reveal the missing piece of the climate puzzle. In classrooms and everyday conversation, explanations of global warming hinge on the greenhouse gas effect. In short, climate depends on the balance between two different kinds […]

2014 Antarctic Ozone Hole Comparable to Previous Years

October 31, 2014


2014 Antarctic Ozone Hole Remains Steady

Scientists from NASA and the National Oceanic and Atmospheric Administration reveal that the overall 2014 ozone hole is smaller than the large holes of the 1998–2006 time frame, and is comparable to 2010, 2012, and 2013. The Antarctic ozone hole reached its annual peak size on September 11, according to scientists from NASA and the […]

Rutgers Study Shows Previous Climate Change Was Caused by the Ocean and the Atmosphere

October 27, 2014


Past Climate Change Was Caused by the Ocean and Atmosphere

New research from Rutgers University provides a deeper understanding of the mechanisms of climate change, revealing that circulation of the ocean plays an important role in regulating the climate. Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new […]

New ScienceCast Video: The Cloudy Future of Arctic Sea Ice

October 16, 2014


The Cloudy Future of Arctic Sea Ice

A new four minute ScienceCast video explores the shrinking coverage of Arctic sea ice and how the reduction could affect worldwide weather. ScienceCasts: The Cloudy Future of Arctic Sea Ice: As climate change continues to hammer Arctic sea ice, pushing back its summertime boundaries to record-high latitudes, NASA is flying an innovative airborne mission to […]

A Magnetic Field Flip Could Occur Over a Short Period of Time

October 15, 2014


Earths Magnetic Field Could Flip Over a Short Time Period

Earth’s magnetic field is decreasing 10 times faster than normal, leading some geophysicists to predict a magnetic reversal to occur within a few thousand years. New research from an international team of scientists shows that this reversal could happen over a short period of time – less than a hundred years. Berkeley — Imagine the […]

Worst Case Scenario Rising Sea Levels of Just Under two Meters

A team of scientists has calculated the risk for a worst-case scenario upper limit for sea level rise within this century, revealing that the sea level could rise 1.8 meters. The climate is getting warmer, the ice sheets are melting and sea levels are rising – but how much? The report of the UN’s Intergovernmental […]

NASA Shows Earths Ocean Abyss Has Not Warmed

Using 2005-2013 data from the Argo buoys, NASA’s Jason-1 and Jason-2 satellites and GRACE satellites, scientists found that deep ocean warming contributed virtually nothing to sea level rise during this period. The cold waters of Earth’s deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of […]

NASA Images Show the Eastern Basin of the South Aral Sea is Dry

Images from NASA’s Terra satellite reveal that the eastern basin of the South Aral Sea is completely dry. This is the first time the eastern basin has completely dried in modern times. Summer 2014 marked another milestone for the Aral Sea, the once-extensive lake in Central Asia that has been shrinking markedly since the 1960s. […]

Satellites Reveal Dip in Gravity from West Antarctica Ice Loss

October 1, 2014


West Antarctica Ice Loss Dips Gravity

The animation, based on measurements from ESA’s GOCE satellite and the NASA–German Grace mission, shows that ice lost from West Antarctica has caused a dip in Earth’s gravity. GOCE was not designed to show changes in gravity over time. However, high-resolution gravity gradients that GOCE measured over Antarctica between November 2009 and June 2012 were […]

Possibility of El Niño Event in 2014 is Fading

September 23, 2014


Prospect of 2014 El Nino

Climatologists believe the latest Kelvin waves are the “last hurrah” for a much-hoped-for El Niño event in 2014. Prospects have been fading for an El Niño event in 2014, but now there’s a glimmer of hope for a very modest comeback. Scientists warn that unless these developing weak-to-modest El Niño conditions strengthen, the drought-stricken American […]

New Model Reveals Spreading Continents Kick-Started Plate Tectonics

September 18, 2014


New Research on What Set the Earths Plates in Motion

New research from the University of Sydney is shedding light on what set the Earth’s massive tectonic plates in motion, suggesting that it was triggered by the spreading of the early continents and eventually it became a self-sustaining process. The mystery of what kick-started the motion of our earth’s massive tectonic plates across its surface […]
