    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.

Hurricane Bonnie Update
News story originally written on August 26, 1998

From the National Weather Service, Miami, Florida, 11 a.m. EDT: Bonnie battering coastal North Carlina...Flood threat from rain increasing...Hurricane warnings remain in effect from Cape Romain, South Carolina to Chinoteague, Virginia, including Pamlico and Albemarle Sounds and Chesapeake Bay from Smith Point Southward. Small craft south of the warning area should remain in port until winds and seas subside.

A hurricane watch remains in effect from Chinoteague to Cape Henlopen Delaware. At 3 p.m. EDT, the center of the hurricane Bonnie was located near latitude 33.7 N, longitude 78.0 W, or about 40 miles south of Wilmington, North Carolina. Bonnie is moving toward the north near 10 mph and this motion is expected to continue today with a gradual turn toward the north-northeast tonight. On this track, the center of Bonnie should reach the coast early tonight. However, this is a large hurricane and hurricane conditions could occur far from the center.

This hurricane is a category 3 storm capable of considerable damage. If this hurricane does reach the U.S. East coast, flooding and high winds could cause a lot of property damage. This hurricane has been very hard to forecast because it is erratic, i.e. it continues to stall overnight and then during the day it continues on its northwest path headed for the East coast.
