    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.

The Southeast Pacific Region

The Southeast Pacific region is a very diverse part of South America. It includes coasts along the ocean and the Andes mountains in Chile and Peru.

The climate of the Southeast Pacific is influenced by the Andes, ocean currents, and winds. These things cause upwelling in the ocean and help keep the ocean and air temperatures cool.

The coast of Peru and northern Chile has a subtropical desert climate. Fog is common on the coast, and the only precipitation is an occasional light drizzle. This area also contains the Atacama Desert, which is one of the driest places on the Earth. The Atacama Desert contains many minerals, including copper. Central Chile has a mild climate and receives more rain than the northern areas.

Chile has some island territories located in the Pacific Ocean, including Easter Island. Easter Island is 3,600 km (2,237 miles) off the coast of Chile and has a humid, subtropical climate.
