    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.

Poetry and Pictures - Weather

British painter John Constable (1776-1837) made many paintings of clouds. It looks like he depicted towering cumulus clouds in this painting of Weymouth Bay. These clouds may have turned into cumulonimbus and a storm later in the day.

The Visitors
by Lucie, age 11, England

It burns in our eyes,
And the glistening skies,
It flies in with the wind,
And in the air it is twinned,
With what keeps us alive,
So by stars we arrive,
In glittering gold,
And souls fierce and bold,
Over the rocky mountains,
And nature's own fountains.
We make our path shine,
And on the ground we sign,
Our mark of light,
Till the end of the night,
When we sleep in our cloud
You would not hear a sound,
Until twilight again,
And then to space we ascend,
Up and away,
As we streak the clouds with grey.
