What the mud tells us about a changing Arctic
September 8, 2017 08:08 AM - NOAA

The back deck of the Healy is a tough place to work.  It’s wet, it’s cold, and the scientists slogging away there are always covered in mud.  That’s because getting samples off the bottom of the Chukchi Sea is an important part of our mission this year.

U.S. had 15th warmest summer and 3rd warmest year to date on record

Team gathers unprecedented data on atmosphere's organic chemistry
September 7, 2017 04:09 PM - Massachusetts Institute of Technology (MIT)

For a few weeks over the summer in 2011, teams of scientists from around the world converged on a small patch of ponderosa pine forest in Colorado to carry out one of the most detailed, extended survey of atmospheric chemistry ever attempted in one place, in many cases using new measurement devices created especially for this project. Now, after years of analysis, their comprehensive synthesis of the findings have been released this week.

Monarch butterflies disappearing from western North America

Monarch butterfly populations from western North America have declined far more dramatically than was previously known and face a greater risk of extinction than eastern monarchs, according to a new study in the journal Biological Conservation.

“Western monarchs are faring worse than their eastern counterparts,” said Cheryl Schultz, an associate professor at Washington State University Vancouver and lead author of the study. “In the 1980s, 10 million monarchs spent the winter in coastal California. Today there are barely 300,000.”
