    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.
Giant waves are pictured in this photo. Waves like this caused by Hurricane Georges could swamp some of the Florida Keys. The hurricane already hit some Caribbean islands with 20-foot waves and storm surges 5 to 10 feet above normal tides. These swells can affect boaters and sailors very far from the eye of the hurricane.

The Latest on Hurricane Georges
News story originally written on September 25, 1998

Hurricane warnings were posted yesterday for much of Southern Florida. More than 1 million people were ordered to evacuate the area from Key West to Tampa.

The eye of the hurricane was expected to pass just south of Key West today by 11 a.m. EDT. Winds are over 100 miles per hour and many in Florida have already experienced power outages. Damage to property and a possible death toll will be known only after Georges has passed the Keys later tonight. After passing the Florida Keys, the hurricane is expected to strengthen to a category 3 storm. It could be a threat to the northern Gulf of Mexico by Saturday.

Georges was once a major hurricane, until it ran into the Caribbean Islands. These Islands acted to slow the hurricane down, keeping it as a category 1 on the Saffir-Simpson scale. This was all tragic news to residents of the Lesser Antilles, Puerto Rico, the Dominican Republic and Haiti. Over 250 people have been killed by the hurricane's trek across the Caribbean.
