    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.

Wildfires are Burning in the Western United States
News story originally written on June 14, 2002

There are 19 large wildfires burning in the United States (as of June 13, 2002). Most of the fires are in the western part of the country. Some fires started when people were careless with fire. Some fires started in natural ways, such as from lightning .

The largest fire is in Colorado. A campfire started the wildfire and it has grown bigger and bigger since Sunday, June 9, 2002. The fire is mostly in forests. Colorado has not had much rain and snow this year so the forests are very dry and will burn easily.

Small wildfires can be good for a forest because they burn dead trees, making more room for living trees to grow bigger. But, large wildfires, like the ones in the West, burn both living and dead trees.

Every fire needs three things: fuel, oxygen and heat. The fuels for a wildfire are plants. The oxygen comes from the air. Very hot temperatures are needed for a fire too. To stop a wildfire, fire fighters try to take at least one of the three things from the fire.

Fire fighters are trying to stop the wildfires in many ways. Some firefighters are on the ground, trying to smother and contain the fire. Some firefighters fly through the air in planes, dropping thick soupy stuff onto fires from above. Also, NASA's Terra satellite look at fires from space and helps people know where fires are by taking pictures like the one here.
