The Arctic is Opening Up: Offshore Drilling and Melting Sea Ice

By Roberta Attanasio, IEAM Blog Editor

The heat is on in the Arctic. This region is now warming at a rate faster than twice the global average—known as Arctic amplification. Consequently, the ice that covers the North Pole and surrounding areas, and melts to its lowest extent each September, has been disappearing at an alarming rate. Continue reading

Insidious Danger: Microplastics Pollute Aquatic Life and Harm Our Food Supply

Microplastics—the tiny bits of plastic that are now infamously and ubiquitously present in the world’s waterways—are polluting aquatic life and ending up in our food supply. As evidence of the damage that microplastics inflict on aquatic life accumulates, so does the amount of microplastics dispersed in oceans, seas, lakes, and rivers. Virtually indestructible in natural environments, these tiny bits of plastic contain a combination of very small particles—microparticles and nanoparticles—that derive from the breakdown of larger plastic items, for example plastic bags and bottles, and include, among others, pre-production plastic pellets (the so-called nurdles), microbeads from personal care products, and microfibers from textiles.

The “Microbead-Free Waters Act”: Saying Goodbye to the Tiny Plastic Fragments That Pollute Our Waterways

Microbeads—tiny, plastic beads added to face scrubs, soap, toothpaste, and the like—cause environmental damage at the macro scale. Their function is to provide a bit of grit, but they end up in lakes, rivers, and other aquatic habitats. Once there, microbeads are mistaken for food and gobbled up by zooplankton, thus becoming incorporated into the aquatic food chain. Small fish, and other organisms that swallow the contaminated zooplankton, are eaten by bigger fish and eventually, microbeads make their way to the top of the food chain, reaching other wildlife and even humans. However, there is more to this story. Continue reading

Let’s Look at Past Successes to Encourage the Vision of a Brighter Environmental Future

A guest post by Brock B. Bernstein

Pervasive doom and gloom dominates much of the popular news about the environment. Global warming, sea level rise, ocean acidification, drought, wildfires, overfishing, or overpopulation—it all contributes to a feeling of despair and hopelessness, particularly among young people. This struck home for me on a personal level during a recent conversation with my college-aged son and a few of his friends—they felt they were “totally screwed” because of the inevitable impacts of climate change.

On August 3, 2015, the Obama administration announced the finalized US Environmental Protection Agency’s (EPA) “Clean Power Plan.” The plan has been developed under the Clean Air Act and aims to slash carbon emissions from US power plants, which account for one-third of all carbon emissions in the country, by giving each state an individual goal for cutting these emissions. The EPA estimates that the new national standards will significantly decrease carbon pollution produced by the electric sector by 2030; carbon emissions will be 32% lower than the 2005 levels. For a step-by-step guide on how the Clean Power Plan works, head here. Continue reading

US Federal Government Taking Aim at Protecting Pollinators

A guest post by Richard J Wenning, Editor-in-Chief, Integrated Environmental Assessment and Management (IEAM).

Next week is National Pollinator Week in the US (June 15-21, 2015), and a good time to consider the importance of bees, birds, butterflies, and bats for a healthy ecosystem. Pollinators contribute more than $24 billion annually to the US economy by tending to the vineyards, orchards, farmlands, nurseries, and countless acres of open space used by tourists every year. Pollinating requires a significant natural work force. But right now, nature’s workers are not doing so well. Continue reading

One of the Best Climate Communication Talks I Have Seen

A guest post by Marshall Shepherd, Director of the Atmospheric Sciences Program, University of Georgia, and author of the Weather Underground blog “From the Mind of J. Marsh WxGeeks Edition”

On April 15, 2015, at the University of Georgia, I wandered over to the Miller Learning Center to hear a talk by Dr. Steve McNulty (Link) with the United States Forest Service and the USDA Southern Regional Climate Hub (@SEClimateHub).

Let me start by saying this was one of the best and most effective climate communication talks that I have ever seen. It was so good that I felt compelled to write this blog to share some of it with you. Continue reading
