the greenland ice sheet is losing nearly 300 gigatons of ice per year. and that works out to thousands of tons of ice being lost from this ice sheet per second. wait a minute, you just said thousands of tons of ice are lost per second. exactly. that works out to a new subdivision worth of homes of ice being lost every second. reporter: joe mcgregor is the mission s deputy project scientist. to collect this data and compare it to previous years, he and the other sciences rely on radar, lasers, and a camera that shoots thousands of photos in flight. what do we have got here? we have multiple instruments onboard, all with the goal of measuring what is going on with the ice underneath us, how it s changing, what its properties are. reporter: our destination for the day was peterman glacier, set in a canyon 15 1/2 miles wide, its walls taller than our plane, which made for a pretty bumpy flight. this glacier is one of the
warmest temperatures ever recorded and the second lowest sea levels. greenland is ground zero for these radical changes. and that is why nasa s operation ice bridge is up here. its mission is to map earth s polar ice and understand its connection to the global climate. cruising altitude on operation ice bridge is 1,500 feet. perfect for an extraordinary view of our climate s changing in realtime. on average, we now know that the greenland ice sheet is losing nearly 300 gig tons of ice per year. and that works out to thousands of tons of ice being lost from this ice sheet per second. wait a minute, you just said thousands of tons of ice are lost per second. exactly. that works out to a new subdivision worth of homes of ice being lost every second. reporter: joe mcgregor is the mission s deputy project scientist. to collect this data and compare it to previous years, he and the other sciences rely on radar,
