A NOAA-sponsored report shows that the warming trend transforming the Arctic persisted in 2017, resulting in the second warmest air temperatures, above average ocean temperatures, loss of sea ice, and a range of human, ocean and ecosystem effects.

Now in its 12th year, the Arctic Report Card, released today at the annual American Geophysical Union fall meeting in New Orleans, is a peer-reviewed report that brings together the work of 85 scientists from 12 nations.

Hundreds of marine turtles die every year after becoming entangled in rubbish in the oceans and on beaches,  including plastic ‘six pack’ holders and discarded fishing gear.  

An international research team led by the Department of Materials Science and Engineering at the Technion-Israel Institute of Technology has discovered how a beautiful, brainless brittle star can create material similar to tempered glass underwater at ambient conditions. The findings, published in the December 8 issue of Science, may open new bio-inspired routes for toughening brittle ceramics in various applications.

Agriculture and domestic activities consume much of the Colorado River water that once flowed to the Colorado Delta and Northern Gulf of California. The nature and extent of impact of this fresh-water loss on the ecology and fisheries of the Colorado Delta and Gulf of California is controversial. A recent publication in the journal PeerJ reveals a previously unseen risk to the unique local biodiversity of the tidal portion of the Delta. 

To help untangle fact from speculation, Cornell climate scientists and their colleagues have developed a “robust null hypothesis” to assess the odds of a megadrought – one that lasts more than 30 years – occurring in the western and southwestern United States. The research was published online Dec. 8 in the Journal of Climate.
