Must-see video on AGU sea level rise research, with Josh Willis and Jason Box: Climate Change and Sea Level Rise: “An Emerging Hockey Stick”

Climate Change and Sea Level Rise: “An Emerging Hockey Stick”

Since we have such an active community of armchair oceanographers and spreadsheet Glaciologists here, I thought it would be useful to speak to the real thing, the people who actually spend time on the ocean, on the ice sheets, do the measurements, and come back to share that knowledge with us. I had just that opportunity at the American Geophysical conference in December.

I spoke to Josh Willis, Oceanographer with NASA at the Jet Propulsion Lab – Josh is one of best known young ocean scientists on the planet. He pointed me to the recent Kemp et al study of tidal marshes on the US East coast, which has produced a long record  of sea level over the last 2,000 years, complete with a very Hockey-stickish uptick during the last 200 or so.

Jason Box of the Byrd Polar Center at Ohio State was there, presenting evidence of acceleration in Greenland ice loss over the last 200 years.

His bottom line – “If we talk 10 years from now, my expectation is that Greenland will be losing roughly double what it is now.”

I round out the video with takes from old pros lead NASA scientist Jim Hansen and Admiral David Titley, the US Navy’s Chief Oceanographer.
