University of Oregon: Large, ancient landslides delivered preferred upstream habitats for coho salmon
A study of the Umpqua River basin in the Oregon Coast Range helps explain natural processes behind the width of valleys and provides potentially useful details for river restoration efforts designed to improve habitats for coho salmon.

NOAA Response and Restoration Blog: Where Are the Pacific Garbage Patches Located?
The Pacific Ocean holds more than half of the planet’s free water, but it also holds a lot of the planet’s garbage (much of it plastic). That trash is not spread evenly across the Pacific Ocean; a great deal of it ends up suspended in large “garbage patches.”

University of Hawaii, Manoa: New research shows complexity of global warming
Global warming from greenhouse gases affects rainfall patterns in the world differently than does solar heating, according to a study published in Nature. Global rainfall has increased less over the present-day warming period than it did during the Medieval Warm Period, even though temperatures are higher today than back then.

Scientific American: Where Few Trees Have Gone Before
With a warming climate, snow has begun melting earlier and growing seasons have lengthened, giving trees a boost at higher elevation. As a result, tree occupation of mountain meadows rose from 8 percent in 1950 to 35 percent in 2008, reports a U.S. Department of Agriculture Forest Service–funded study published last October in Landscape Ecology.

Science Daily: Flood Research Shows Human Habits Die Hard: Few Make Plans to Cut Vulnerability
Research findings from Australia indicate that while households can minimize damage from floods, most people — even those recently affected by major flooding — do not  intend to make changes to reduce their vulnerability to future floods.
