Arctic River Ice Deposits Rapidly Disappearing

Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds.

Cover crops may be used to mitigate and adapt to climate change
April 17, 2017 04:08 PM - Penn State

Cover crops long have been touted for their ability to reduce erosion, fix atmospheric nitrogen, reduce nitrogen leaching and improve soil health, but they also may play an important role in mitigating the effects of climate change on agriculture, according to a Penn State researcher.

New era of western wildfire demands new ways of protecting people, ecosystems
April 17, 2017 04:00 PM - University of Colorado Boulder

Just four weeks ago, fire crews battled the Sunshine fire in the foothills west of Boulder. Low humidity, record-high temperatures and 40 mile-per-hour gusts of wind helped fan flames that forced over 1,000 people to evacuate their homes. Firefighters quickly contained the wildfire, with no injuries or damage reported. But the reality of a blaze this serious in March raises concerns about how we deal with wildfire in the western United States.

NASA Spots Tropical Cyclone 02W's Remnants in South China Sea
April 17, 2017 03:51 PM - NASA / Goddard Space Flight Center

The remnants of former Tropical Depression 02W still lingered in the South China Sea when NASA's Terra satellite passed overhead on April 17.

Tropical Depression 02W made landfall along the east coast of the eastern Visayas around 1500 UTC/11 a.m. EST) on Saturday, April 15, 2017. At 0900 UTC (5 a.m. EST) Tropical Depression 02W had maximum sustained winds near 25 knots as it neared the eastern Philippines. At that time, the Joint Typhoon Warning Center issued their final bulletin on the storm and said that satellite imagery showed weak development of thunderstorms and that bands of thunderstorms were diminishing.  It was centered near 11.4 degrees north latitude and 125.9 degrees east longitude, about 373 nautical miles east-southeast of Manila, Philippines, was moving to the west-northwest and moved in that direction over the central Philippines

Retreating Yukon glacier caused a river to disappear
April 17, 2017 03:34 PM - Hannah Hickey via University of Washington

The massive Kaskawulsh Glacier in northern Canada has retreated about a mile up its valley over the past century.

Last spring, its retreat triggered a geologic event at relatively breakneck speed. The toe of ice that was sending meltwater toward the Slims River and then north to the Bering Sea retreated so far that the water changed course, joining the Kaskawulsh River and flowing south toward the Gulf of Alaska.

New Infrared-Emitting Device Could Allow Energy Harvesting from Waste Heat
April 13, 2017 10:51 AM - The Optical Society

A new reconfigurable device that emits patterns of thermal infrared light in a fully controllable manner could one day make it possible to collect waste heat at infrared wavelengths and turn it into usable energy.
