    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.

Huge Oil Spill in Gulf of Mexico

A large oil drilling rig in the Gulf of Mexico caught fire and sank in April 2010. Eleven workers were killed in the accident.

After the oil rig sank, a huge oil slick formed in the Gulf of Mexico. The oil slick is near the mouth of the Mississippi River. Clean-up crews haven't yet (as of April 28th) been able to close off the damaged oil well. Each day about 200,000 gallons of oil are leaking into the waters of the Gulf of Mexico. The oil slick has a size of about 600 square miles. It is less than 20 miles from the shore of Louisiana.

The Coast Guard set fire to part of the oil slick to try to get rid of some of the oil. They may try to burn more of it. They hope to stop the oil from coming ashore at wildlife refuges along the coast of Louisiana and Mississippi. If the oil reaches the shore, it would harm birds and other wildlife.
