Notice in the Peter Sinclair video where Dr. Alley is speaking outside, and the entire mountain side behind him is dead pine trees.

Great videos. I am particularly entranced by the record of the slow accumulation of data on a hard honest route created by the Mauri Pelto team. People don't realize science doesn't just whizzbang; it relies on patience and accuracy by the careful route.

Another example of the value of long term data gathering.


Wal, I was struck by the same thing in that video--all those people doing the same, mundane measurements all over the world for years and years. Quite amazing and impressive.

Dec. 6, 2013 — A new NASA-led study has discovered an intriguing link between sea ice conditions and the melting rate of Totten Glacier, the glacier in East Antarctica that discharges the most ice into the ocean. The discovery, involving cold, extra salty water -- brine -- that forms within openings in sea ice, adds to our understanding of how ice sheets interact with the ocean, and may improve our ability to forecast and prepare for future sea level rise...................

Satellite observations from NASA's ICESat-1, which measures how much ice surfaces are rising or falling over time, revealed that Totten Glacier was thinning rapidly. It currently discharges enough ice into the surrounding ocean to fill Lake Erie in just over a week. The nearby Moscow University Glacier and its floating ice shelf were showing little change. Why the difference? "We were convinced that the answer must be in the ocean," Khazendar said.
