Which Greenhouse Gas Does the Most Damage to Crops?

Alexandra Branscombe, Freelance Writer

From Research Spotlights— Models showed that approximately 93% of crop losses over the rest of the century could be caused by non–carbon dioxide emissions, the most damaging of these being methane. Scientists and policy makers alike have recognized that agricultural yields are at risk from.... more

Measuring Progress Toward Sustainable Goals

From Research Spotlights— Grouping targets that need to be hit into composite goals may help countries evaluate their progress toward sustainable development targets laid out by the United Nations. On 25 September 2015, 193 countries of the United Nations (UN) General Assembly came together.... more

Watch Your Language

Richard B. Norgaard, Editor

From Editors’ Vox— Legacy words and the search of a new human-environment dynamic Words have legacies. “Nature” and “natural” connote a world apart from people. They also set a standard as to how things “should be.” Yet, there are few places on earth where a fluvial geomorphologist can work,.... more

Evaluating the Impact of Maryland’s Healthy Air Act

Terri Cook, Freelance Writer

Many regions of the United States suffer from air pollution severe enough to harm human health. To alleviate such conditions, the state of Maryland implemented its landmark 2009 Healthy Air Act, the East Coast’s strictest power plant emissions law. The first phase reduced emissions of sulfur dioxide,.... more

Eating Less Meat, Wasting Less Food Could Save Water Worldwide

Sarah Stanley, Freelance Writer

By 2050, the Earth’s population is expected to exceed 9 billion people. We will need 50%–70% more food than is produced today, and without significant changes, many—if not most—people will be affected by water scarcity. Climate change will further strain water supplies in many regions, making it even.... more

Climate Models Predict Diverse Arctic Ocean Shipping Routes

Sarah Stanley, Freelance Writer

As climate change progresses, the Arctic Ocean gets closer to becoming ice-free during warmer months. Scientists expect new shipping routes to open up, creating new possibilities for transport and trade between the North Atlantic and the North Pacific. However, different climate models give different.... more

Antarctic Meltwater Makes the Ocean Warmer and Fresher

Cody Sullivan, Writer Intern

It’s well known that anthropogenic warming will affect global climate and sea levels far into the future. At the edges of ice sheets and glaciers, water, air, and ice all come together in a complex union that carries implications for predicting climate in the future. As global temperatures rise, ice.... more

Sea Level Rise Due to Warming and Weakening of Greenland Glaciers

David Shultz, Freelance Writer

The melting of glaciers is one of the most dramatic and palpable symptoms of climate change. Roughly half of the total sea level rise between 1993 and 2007—approximately 46 millimeters—can be attributed to terrestrial ice melting or calving into the sea. In a recent study, Colgan et al. use a mathematical.... more

To Help Fix the Hole in the Ozone Layer, Just Add Ice

David Shultz, Freelance writer

For better or for worse, the hole in the Earth’s ozone layer above Antarctica has become a symbol of anthropogenic changes to the atmosphere since its discovery in the 1980s. Thirty years later, agreements between the world’s nations, such as the Montreal Protocol, have reduced the quantity of ozone-depleting.... more

Regional Nuclear War Could Cause a Global Famine

Kate Wheeling, Freelance Writer

Nuclear winter has captured the collective imagination of the world since the uneasy days of the cold war between the United States and the Soviet Union. In this hypothetical climate scenario, smoke from the fires ignited by nuclear explosions blocks out the Sun, leaving the Earth’s surface dark, cold,.... more Earth & Space Science News
