Just three months into 2016 and already global temperatures – particularly in the Arctic – are far warmer than normal. Global temperatures for February were the warmest on record for that month.\r
Nowhere is this warming trend felt more than in the\rArctic where the unusual wintertime warmth has contributed to record low wintertime sea ice extent. Arctic sea ice keeps the Polar Regions cold and helps regulate global temperatures. The shrinking of sea ice is a key indicator of our planet’s health.\rNASA is monitoring the health of the Arctic from space and the ground. In the coming days NASA will launch two missions – Operation Ice Bridge and OMG (Oceans Melting Greenland). These airborne and ground campaigns to the Arctic will take measurements of sea ice and glacier thickness.\r

Suggested Questions:\r
1. What do the latest images show us about this year’s winter in the Arctic?\r
2. What do the images tell us about the long-term trend?\r
3. NASA is getting ready to send out teams of scientists to the Arctic in the coming\rdays. What will they be doing?\r
4. Where can we learn more?\r

"title": "The Polar Jet Stream",
"description": "Meandering around the planet like a rollicking roller coaster in the sky, the Northern Hemisphere's polar jet stream is a fast-moving belt of westerly winds that traverses the lower layers of the atmosphere. The jet is created by the convergence of cold air masses descending from the Arctic and rising warm air from the tropics. Deep troughs and steep ridges emerge as the denser cold air sinks and deflects warm air regions north, giving the jet stream its wavy appearance. This pattern propagates across the mid-latitudes of North America, Europe and Asia, as pockets of cold air sporadically creep down from the Arctic - creating contrasting waves and flows that accelerate eastward due to Earth's rotation. Running from June 10 to July 8 of 1988, the visualization below uses weather and climate observations from NASA's MERRA dataset to model nearly a month of the jet stream's whirling journey over North America. || ",

"title": "Racing off the Edge of Greenland",
"description": "Once known for its size, the Jakobshavn Glacier in Greenland is now studied for its speed. In 1997 Jakobshavn ended a decades-long period of stability as it began to thin, accelerate and eject ice into the sea at a rapid rate. The glacier thinned by as much as 50 feet (15 m) per year between 1997 and 2003, according to NASA laser altimetry measurements, while other Greenland glaciers were thinning by about three feet (1 m) per year. The glacier now moves at more than nine miles (15 km) per year, doubling its speed from a decade ago. The glacier's calving front has retreated more than six miles (10 km) in the past decade alone. Scientists point to several warming-related causes for the increase in speed and retreat: meltwater can trickle through cracks in the ice and lubricate the friction point between ice and bedrock, and warmer ocean waters underneath the ice shelf also cause thinning. The thinner ice shelf and meltwater reduce resistance to glacier movement. As a glaciology case study and the greatest potential contributor to sea level rise in the Northern Hemisphere, scientists will continue to watch Jakobshavn closely. || ",
