    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.

Flying from Pole to Pole to Measure Greenhouse Gases
News story originally written on January 7, 2009

HIAPER, one of the nation's most advanced research aircraft, is scheduled to embark on an historic mission spanning the globe from the Arctic to the Antarctic.

Starting Jan. 7, 2009, the HIAPER Pole-to-Pole Observations (HIPPO) mission will cover more than 24,000 miles as an international team of scientists makes a series of five flights over the next three years sampling the atmosphere in some of the most inaccessible regions of the world.

The goal of the mission is ambitious--the first-ever, global, real-time sampling of carbon dioxide and other greenhouse gases across a wide range of altitudes in the atmosphere, literally from pole-to-pole.

To date, much of our understanding of global atmospheric greenhouse gases has been acquired from ground-based observations, distant satellites, balloon launches, or highly sophisticated supercomputer models. HIAPER's pole-to-pole mission will, for the first time, give scientists real-time global observation data to correlate with those climate models.

HIAPER is short for the National Science Foundation's High-performance Instrumented Airborne Platform for Environmental Research. A modified Gulfstream V jet, it can fly at high altitudes for extended periods of time and can carry 5,600 pounds of sensing equipment, making it a premier aircraft for scientific discovery.

HIPPO is a joint project funded by the National Science Foundation and the National Oceanic and Atmospheric Administration and involving researchers from Harvard University, NSF's National Center for Atmospheric Research and the Scripps Institution of Oceanography.
