    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.

Inuit Culture in a Warming Arctic

The Arctic is warming quickly, faster than other places on Earth. Inuit people who live there have been noticing the change.  Because their culture is adapted to the Arctic’s cold climate, global warming is making it difficult for Inuit people to continue their traditions.
 
Several Canadian Inuit groups got together recently to record what climate change means to them.  They recorded the changes that they observed and how people were coping with these changes.

Here are a few of their observations in their own word:

  • “We need to be more careful when pursuing animals because of thinner ice and changing ice conditions,” said an Inuit from the Nunavut Territory.
  • “The water from some rivers and ponds smells and tastes bad, particularly when it does not rain for quite some time. We do not want to drink this water,” said a Nunatsiavut Inuit.
  • “Caribou are a lot skinnier,” noted an Inuit. “And the caribou don’t look as healthy as they used to.” 

Like the comments above, a lot of the observations that the Inuit recorded were things that had a negative impact. They reported an increase in sunburns and a decrease in their ability to predict the weather, for example.  Some of their observations were positive. With the warmer climate, animals that usually live further south have moved further north and these species can be new food sources for the Inuit, for example.

What do these changes to the environment mean for the Inuit way of life?  “Inuit are going to have to find new ways to make a living from the land,” said Jose A. Kusugak, a Canadian Inuit.  He continued that, “our millennia-old traditions are already being altered because of the warming Arctic, and we face the possibility of having to completely reinvent what it means to be Inuit. This is a prospect we fear.”
