Greatest threat to eastern forest birds is habitat loss on wintering grounds

Mon, 24 Jul 2017 00:00:00 EDT

(Cornell University) Human-caused habitat loss looms as the greatest threat to some North American breeding birds. The problem will be most severe on their wintering grounds, according to a new study published today in the journal Global Change Biology.

Special policy forum with Rep. Bonamici at the 2017 Ecological Society Annual Meeting

Mon, 24 Jul 2017 00:00:00 EDT

(Ecological Society of America) The political landscape has become more challenging to navigate for scientists seeking to inform policy. In response to ecologists' increased motivation to effectively engage in the political scene, this year's Annual Meeting of the Ecological Society of America will feature a new event to examine the current national political landscape from the ecological science perspective. This Special Policy Forum will take place on Monday, August 7 at the Society's 102nd Annual Meeting in Portland, Oregon.

(NASA/Goddard Space Flight Center) Earlier this year Arctic sea ice sank to a record low wintertime extent for the third straight year. Now NASA is flying a set of instruments north of Greenland to observe the impact of the melt season on the Arctic's oldest and thickest sea ice.



The coast is not so clear

Mon, 24 Jul 2017 00:00:00 EDT

(University of California - Santa Barbara) For nearly a century, the O'Shaughnessy seawall has held back the sand and seas of San Francisco's Ocean Beach. At work even longer: the Galveston seawall, built after America's deadliest hurricane in 1900 killed thousands in Texas.

Mon, 24 Jul 2017 00:00:00 EDT

(NASA/Goddard Space Flight Center) Tropical Storm Greg appears to be less-rounded and more elongated on satellite imagery from NOAA's GOES-West satellite. Greg is still over 1,500 miles east of Hawaii.



NASA sees Tropical Depression Roke over Hong Kong

Mon, 24 Jul 2017 00:00:00 EDT

(NASA/Goddard Space Flight Center) NASA's Terra satellite captured Tropical Depression Roke over Hong Kong after it made landfall on July 23.



Could 'cocktail geoengineering' save the climate?

Mon, 24 Jul 2017 00:00:00 EDT

(Carnegie Institution for Science) Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth's energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical Research Letters investigates for the first time the possibility of using a 'cocktail' of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases.



NASA watches as Vietnam braces for Tropical Storm Sonca

Mon, 24 Jul 2017 00:00:00 EDT

(NASA/Goddard Space Flight Center) NASA's Aqua satellite took a look at an elongated Tropical Storm Sonca in the South China Sea as it approached Vietnam where it is expected to make landfall. Tropical Depression 08W strengthened into a tropical storm on July 23 and was renamed Sonca.



TPU scientists equip chemical sensors with 'traps' to detect toxic substances

Mon, 24 Jul 2017 00:00:00 EDT

(Tomsk Polytechnic University) Scientists from Tomsk Polytechnic University and the University of Chemistry and Technology (Prague, Czech Republic) have created novel chemical sensors for Raman spectrometers. Having combined physical and chemical methods scientists obtained highly sensitive sensors for determining dyes prohibited in Europe and heavy metals in water at ultralow concentrations. The process of analysis lasts a couple of minutes, so the sensors are appropriate for using in mobile laboratories.



'Hindcasting' study investigates the extreme 2013 Colorado flood

Mon, 24 Jul 2017 00:00:00 EDT

(DOE/Lawrence Berkeley National Laboratory) Using a publicly available climate model, Berkeley Lab researchers 'hindcast' the conditions that led to the Sept. 9-16, 2013 flooding around Boulder, Colo. and found that climate change attributed to human activity made the storm much more severe than would otherwise have occurred.



Two undergrads improve plant carbon-cycle models

Mon, 24 Jul 2017 00:00:00 EDT

(University of Illinois at Urbana-Champaign) In the summer of 2012, two undergraduate students tackled a problem that plant ecology experts had overlooked for 30 years. The students demonstrated that different plant species vary in how they take in carbon dioxide and emit water through the pores in their leaves. The data boosted the accuracy of mathematical models of carbon and water fluxes through plant leaves by 30 to 60 percent.



Allowable 'carbon budget' most likely overestimated

Mon, 24 Jul 2017 00:00:00 EDT

(Penn State) While most climate scientists, including the Intergovernmental Panel on Climate Change, implicitly define 'pre-industrial' to be in the late 1800s, a true non-industrially influenced baseline is probably further in the past, according to an international team of researchers who are concerned because it affects the available carbon budget for meeting the 2 degrees Celsius (3.6 degrees Fahrenheit) warming limit agreed to in the Paris Conference of 2015.



Study: Indian monsoons have strengthened over past 15 years

Mon, 24 Jul 2017 00:00:00 EDT

Fri, 21 Jul 2017 00:00:00 EDT

(Duke University) Everyone knows that exposure to pollution during rush hour traffic can be hazardous to your health, but it's even worse than previously thought. In-car measurements of pollutants that cause oxidative stress found exposure levels for drivers to be twice as high as previously believed.

Mountain glaciers recharge vital aquifers

Thu, 20 Jul 2017 00:00:00 EDT

(University of Alaska Fairbanks) Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study published in Geophysical Research Letters, a journal of the American Geophysical Union.The study also suggests that the accelerated melting of mountain glaciers in recent decades may explain a phenomenon that has long puzzled scientists -- why Arctic and sub-Arctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall.
