New details of Greenland ice loss revealed

The National Aeronautics and Space Administration (NASA) has stated that its Oceans Melting Greenland (OMG) project is revealing new details about thinning of the Greenland polar icecap. In particular, OMG observations have been depicted in two new research papers in order to document how meltwater and ocean currents are interacting along Greenland's west coast and to improve seafloor maps used to predict future melting and subsequent sea level rise.

Growing Arctic carbon emissions can go unobserved

A new NASA-led study has found that in at least part of the Arctic, scientists are not doing as good a job of detecting changes in carbon dioxide during the long, dark winter months as they are at monitoring changes during the short summer. That's a concern, because growing Arctic plants can act as a brake on global warming rates by removing carbon from the atmosphere, but increasing cold-season emissions could overwhelm the braking effect and accelerate global warming.

Ocean currents to be tracked from space

 A new method of tracking ocean currents from space has been developed by NASA scientists and verified using data from the National Oceanography Centre (NOC).The importance of these ocean currents as a driving force in the global climatic system is increasingly being recognised. By helping to monitor changes in currents, this new method could help improve long-term forecasts. 

Researchers at NASA have developed a means of measuring the flow rate of water masses in deep ocean currents by detecting the tiny changes they cause to Earth’s gravity field. A study, published in the journal of Geophysical Research letters, reveals how gravitational data from the twin satellites of NASA's Gravity Recovery and Climate Experiment (GRACE) mission, has been used to calculate the flow rate of a current system in the Atlantic. 

This system is known as the Atlantic Meridional Overturning Circulation (AMOC). It is responsible for the transfer of a great deal of heat and nutrients from the tropics to North West Europe, contributing to our relatively mild climate. 
 
“In principle, you’d think you’d have to measure every ten yards or so across the ocean to know the whole flow. In fact if you can measure the farthest eastern and western points very accurately ...

Antarctica Might Be Melting, But It's Actually Growing

https://www.youtube.com/watch?v=f1jHnxxEuDM NASA says although some of Antarctica's ice is melting, other parts are growing so fast the ice sheet is actually slowing sea level rise.Find further information by reading related articleMass gains of Antartic Ice Sheet greater than lossesIn the starting, I was explicit with you propecia before and after has changed my essence. It has become much more fun, and now I have to run. Just as it is incredible to sit.

Mass gains of Antarctic Ice Sheet greater than losses

A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.“We’re essentially in agreement with other studies that show an increase in ice discharge in the Antarctic Peninsula and the Thwaites and Pine Island region of West Antarctica,” said Jay Zwally, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study, which was published on Oct. 30 in the Journal of Glaciology.“Our main disagreement is for East Antarctica and the interior of West Antarctica – there, we see an ice gain that exceeds the losses in the other areas.”  Zwally added that his team “measured small height changes over large areas, ...
