Ice Loss Accelerating in Greenland’s Coastal Glaciers

HANOVER, N.H. – Surface meltwater draining through and underneath Greenland’s tidewater glaciers is accelerating their loss of ice mass, according to a Dartmouth study that sheds light on the relationship between meltwater and subglacial discharge. The findings appear in the journal Annals of Glaciology. A PDF is available on request. Greenland has the potential to

Insect Outbreaks Reduce Wildfire Severity

Forest scientists have found an unexpected ‘silver lining’ to the insect outbreaks that have ravaged millions of trees across western North America. While insect outbreaks leave trees looking like matchsticks, a new University of Vermont-led study finds these hungry critters significantly reduce wildfire severity. The findings contrast sharply with popular attitudes – and some U.S.

City, Corporate Actions are Crucial to Global Climate Response, Researchers Say

At the UN this week envoys from more than 130 nations, including 60 world leaders, will convene to sign the Paris Climate Change Agreement. This historic deal, achieved during global climate talks last December, was bolstered by contributions from hundreds of city mayors and corporate CEOs who made their own climate pledges during the negotiations.

Greenness Around Homes Linked to Lower Mortality

Women live longer in areas with more green vegetation, according to new research funded by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health. Women with the highest levels of vegetation, or greenness, near their homes had a 12 percent lower death rate compared to women with the lowest

Fertilizer’s Legacy: Taking a Toll on Land and Water

Tempe, Ariz.—The world’s total human population has jumped to over 7.4 billion just this year. Feeding the human species takes a tremendous toll on our natural resources including water, soil and phosphorus — a chemical element in fertilizer essential for food production. In modern agriculture, fertilizer often leaks into waterways such as rivers, lakes and

Climate Science Project Aims to Understand Amazon Impacts

Further understanding the links and interactions between the Brazilian Amazon rainforest and the world’s climate is the focus of a major new research programme, funded by the Newton Fund The three-year £4-million program, known as Climate Science for Service Partnership (CSSP) Brazil, will bring together scientific researchers and organisations from the UK and Brazil, in

Methane from Some Wetlands May Lower Benefits of Carbon Sequestration

Sacramento, Calif. – Methane emissions from restored wetlands may offset the benefits of carbon sequestration a new study from the U.S. Geological Survey suggests. Wetlands are known to reduce atmospheric carbon dioxide through plant photosynthesis and also provide habitat and food sources for wildlife, act as biological filters for improving water quality and improve coastal

Australian Researchers Use Surveillance Cameras and Drones to Spy on Trees

A scientist from The Australian National University (ANU) is helping set up an international network to use surveillance camera networks and drone data to spy on trees. The network will help make huge amounts of time-lapse image data accessible for scientists trying to understand how climate change will affect forests around the world. Dr Tim

Rainier Winters Occur Across the United States

Across the U.S., a greater percentage of winter precipitation is falling as rain, with potentially severe consequences in Western states where industries and cities depend on snowpack for water, and across the country wherever there is a winter sports economy.

New Cause of Exceptional Greenland Melt Revealed

A new study by researchers from Denmark and Canada’s York University, published in Geophysical Research Letters, has found that the climate models commonly used to simulate melting of the Greenland ice sheet tend to underestimate the impact of exceptionally warm weather episodes on the ice sheet. The study investigated the causes of ice melt during
