    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.

Arctic Cultures

Inuit

Inuit people live in the chilly northern parts of Canada, Alaska (USA), Siberia (Russia), and Greenland. There are many different groups of people in this large area. Most have similar ways of living in the Arctic. Inuit traditionally hunted for seals, whales, polar bears, caribou, birds and other animals from the Arctic ocean and Arctic tundra. The magical appearance of the aurora in the night sky, the long dark winters, and the icy Arctic Ocean inspired the myths of the Inuit people.

Norse

Norse people were originally from the northern part of Europe. More than a thousand years ago, groups of Norse explorers and warriors called Vikings settled in other places in the Arctic such as Greenland, Iceland, and northern Russia. Today, many people living in these countries are relatives of the Norse. The Norse got to these new places by boat. Norse people knew how to make very strong boats. The Norse people, including the Vikings, were known to be excellent storytellers. Explore some Norse myths in the links below.
