Antarctic & Greenland Melt Accelerates Sea Level Rise

In this talk from October 2019, Eric Rignot suggests the possibility of 4 meters of sea level rise per century. Just extrapolating based on Antarctic marine glaciers retreating would yield the figure Notes a new model with results in the ballpark Notes the figure is in agreement with past sea level rise estimates Not mentioned…

Eric Rignot: On the Current State of Sea Level Rise Estimates (2019)

Glaciologist Eric Rignot (NASA/JPL) speaking at the American Philosophical Society meeting April 2019. Climate warming caused by human activities has woken up the sleeping ice giants in Greenland and Antarctica, elevating risks of multiple meters of sea level rise in the coming centuries. Rignot will discuss how satellites, airborne platforms, robotic devices and advanced numerical…

The Mystery of the Antarctic Sea Ice Puzzle, Sea ice Plummeting

The amount of ice circling Antarctica is suddenly plunging from a record high to record lows, baffling scientists. A new NASA study by sea ice expert Claire L. Parkinson reveals recent trends in Antarctica’s sea ice extent. CREDITS A 40-y record reveals gradual Antarctic sea ice increases followed by decreases at rates far exceeding the…

Eric Rignot: Response of the Great Ice Sheets to Climate Warming

In ca 2012, as part of the Discover the Physical Sciences Breakfast Lecture Series at the University of California, climate researcher Eric Rignot (NASA/JPL) outlined our understanding of changes in the major cryosphere hotspots in Antarctica and Greenland, in his talk titled “Response of the Great Ice Sheets to Climate Warming”. Read about his newest…
