    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

    Earth's Center Is 1,000 Degrees Hotter Than Previously Thought, Synchrotron X-Ray Experiment Shows

    Scientists have determined the temperature near the Earth’s center to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. For more information about this study, see the press release from the European Synchrotron Radiation Facility.

    Ocean Volcanic Rocks Contain Samples of Recycled Crust

    Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Their work is published in Nature. Oceanic crust sinks into the Earth’s mantle at so-called subduction zones, where two plates come together. Much of what happens to the crust during this journey is unknown. Model-dependent studies for how long subducted material can exist in the mantle are uncertain and evidence of very old crust returning to Earth’s surface via upwellings of magma has not been found until now. For more information about these results, see the press release from the Carnegie Institution.
Bob Bindschadler has been studying ice in Antarctica and Greenland since the early 1980s.

Dr. Robert ("Bob") Bindschadler

Dr. Robert Bindschadler has led 14 field expeditions to Antarctica over the past three decades studying the dynamics of the ice sheet. While making field measurements is necessary to determine how the ice sheet is behaving and why, seeing the "big picture" from space is equally important. Dr. Bindschadler has spent his career combining the two perspectives developing numerous unique applications of remote sensing data for glaciological research such as measuring ice velocity and elevation using both visible and radar imagery, monitoring melt of the ice sheet by microwave emissions, and detecting changes in ice-sheet volume by repeat space-borne radar altimetry.

Beyond his childhood joys of building snowmen and engaging in snowball battles, Dr. Bindschadler's interest in ice deepened when he saw glaciers for the first time in the Canadian Rockies during his teenage years. It was this fascination that led him to apply his skills as a modeler of evolving stars to ice flow. Starting with doctoral research on a surging mountain glacier in Alaska, he ultimately traveled to Antarctica in 1982 to begin a new research project on ice streams. Subsequent research has taken him to Greenland and various glaciers throughout the world but his focus has remained on Antarctica.

He has testified before Congress and briefed the U.S. Vice President on the issue of ice-sheet stability and served on many scientific commissions and study groups as an expert in glaciology and remote sensing of ice. In his 28 years at NASA's Goddard Space Flight Center, he has published over 140 scientific papers, numerous review articles and has appeared on television, radio and is often quoted in print media commenting on glaciological impacts of the climate on the world's ice sheets and glaciers. He is Chief Scientist of the NASA's Hydrospheric and Biospheric Sciences Laboratory, a Senior Fellow of the Goddard Space Flight Center, a Fellow of the American Geophysical Union and a past President of the International Glaciological Society. Bindschadler Glacier (in the Dry Valleys) and Bindschadler Ice Stream (in West Antarctica) have been named in recognition of his contributions to Antarctic glaciology.
