In Harm's Way
November 27, 2017 04:11 PM - University of California - Santa Barbara

How safe is the water you drink? For the 45 million Americans who get their drinking water from private groundwater wells rather than a public utility, the answer is decidedly murky. The Environmental Protection Agency regulations that protect public drinking water systems don’t apply to privately owned wells, leaving owners responsible for ensuring their water is safe from contaminants.

Engineers Model the California Reservoir Network
November 23, 2017 01:15 PM - California Institute of Technology

For the first time, engineers at Caltech have developed an empirical statewide model of the California reservoir network. The model was built from data gathered over a 13-year period that includes the latest drought, allowing researchers to make observations about how 55 of the state's major reservoirs respond to a variety of external conditions as a unified system.

Climate Change Could Increase Volcano Eruptions
November 23, 2017 12:21 PM - University of Leeds

A new study, led by the University of Leeds, found there was less volcanic activity in Iceland when glacier cover was more extensive. As the glaciers melted, volcanic eruptions increased due to subsequent changes in surface pressure.

Methane Bubbles Are Effect and Cause of Rise in Temperature
November 22, 2017 01:53 PM - Radboud University Nijmegen

"Never before have such unequivocal, strong relationships between temperature and emissions of methane bubbles been shown on such a wide, continent-spanning scale.", says biologist Sarian Kosten of Radboud University.

The Social Cost of Carbon Doubles
November 22, 2017 09:29 AM - University of California – Davis

The “social cost of carbon” — an influential figure used by policymakers to weigh the value of efforts that reduce greenhouse gas emissions — is outdated and underestimated. Updated estimates focused on the agricultural sector alone more than double the social cost of carbon, according to analysis from the University of California, Davis, and Purdue University.

Albatrosses in decline from fishing and environmental change
November 21, 2017 01:49 PM - British Antarctic Survey

The populations of wandering, black-browed and grey-headed albatrosses have halved over the last 35 years on sub-antarctic Bird Island according to a new study published today (20 November) in the journal Proceedings of the National Academy of Sciences.

In bee decline, fungicides emerge as improbable villain
November 21, 2017 01:45 PM - Cornell University

When a Cornell-led team of scientists analyzed two dozen environmental factors to understand bumblebee population declines and range contractions, they expected to find stressors like changes in land use, geography or insecticides.

Nebraska Approves Keystone XL, But Requires Different Route Through State
November 20, 2017 05:44 PM - Yale Environment 360

Nebraska regulators have given the final approval for the Keystone XL pipeline to run through their state, eliminating the last major regulatory obstacle preventing the completion of the 1,179-mile pipeline system that would help carry tar sands oil from Alberta, Canada to refineries in Texas.

Low dose, constant drip: Pharmaceuticals & personal care products impact aquatic life
November 15, 2017 11:41 AM - Cary Institute of Ecosystem Studies

Traditional toxicity testing underestimates the risk that pharmaceutical and personal care product pollution poses to freshwater ecosystems. Criteria that account for ecological disruption – not just organism death – are needed to protect surface waters, which are under pressure from a growing population and escalating synthetic chemical use. So reports a new study published this week in Elementa.

Urgent action for planetary health: International Health Lecture
November 14, 2017 10:17 AM - Academy of Medical Sciences (UK)

We need to pay more attention to the health of the planet to save lives, and improve global health, now and in the future, Dr Samuel Myers said at The 2017 Academy of Medical Sciences & The Lancet International Health Lecture
