Bubbling Up: Methane from Reservoirs Presents Climate Change Challenge

By Rose Keane

EPA researcher Jake Beaulieu spends a lot of his time on the water, especially at Harsha Lake, a reservoir just southeast of Cincinnati, OH. He’s not a sailor, nor does he work with marine life. Instead, Beaulieu studies how methane (CH4)—a less discussed but more powerful greenhouse gas than carbon dioxide—is emitted from reservoirs. He and other EPA researchers are developing new models and tools to improve methane emission estimates in reservoirs and our understanding of their contributions to greenhouse gas levels globally.

Beaulieu’s team using a new surveying technique to measure methane emissions from reservoirs.

Beaulieu’s team is applying surveying techniques in novel ways to estimate methane emissions.

Methane gas contributes to rising temperatures and one way it is produced is by tiny organisms in sediments at the bottom of lakes. One important source of food for these organisms is decaying algae, which is converted to methane when eaten by these tiny organisms.

According to Beaulieu, the way that methane emission rates from reservoirs are currently estimated doesn’t take into account a number of factors that can affect how much is emitted into the atmosphere such as the location, water depth, overall size of the reservoir and other conditions.

One of the main ways that large amounts of methane are released from reservoirs is through something called ebullition—or more simply, the bubbles that come up from the mud. The bubbles are filled with methane, and Beaulieu’s research has shown that in areas where the water is deeper and less disturbed, there’s less of these methane bubbles coming to the surface. In areas where the water is more shallow or more frequently disturbed, there’s not enough weight (from the atmosphere or from the water itself) to hold the bubbles in, so emissions increase.

In April this year, 177 countries and states across the world signed the Paris Agreement on Climate Change—a landmark agreement that outlines ways for countries to limit their greenhouse gas emissions, encourage more sustainable infrastructure and economic development, and better plan for responding to the impacts of changing climatic conditions. Beaulieu says that improved estimates of methane emissions from reservoirs will result in better information that can aid in the global effort to reduce greenhouse gas emissions.

His paper, Estimates of reservoir methane emissions based on a spatially balanced probabilistic survey, was recently published in Limnology and Oceanography.

Climate Change…By the Seashore

By Andy Miller, Ph.D.

As the summer winds down, many of us return to school or work with fond memories of trips to the seashore. For me and for many others, where the ocean meets the land are places that are deeply relaxing, reminders of our connections with the natural world.

For several EPA researchers, the shores and estuaries that we value for their beauty and wonder are the sites for investigating the rich and complex ecosystems that support a multitude of species and provide us with benefits well beyond a calming walk along the shore.

Researchers have recently published results of work examining how different impacts of climate change are affecting coastal ecosystems. They demonstrate how vulnerable these natural resources are to drought, sea level rise, and other impacts of a changing climate.

Several studies looked at how the effects of climate change affected cordgrass, dominant salt marsh plants that are key to the vitality of salt marsh ecosystems in southern New England coastal wetlands. One study looked at how saltmeadow cordgrass, Spartina patens, responded to drought and sea level rise in a greenhouse set up for research. This study found that sea level rise was a threat to the long-term survival of the species. The loss of saltmeadow cordgrass would reduce the wetlands’ habitat quality, plant diversity, carbon sequestration, erosion resistance and coastal protection.

A second study examined smooth cordgrass, Spartina alterniflora, under similar stresses, and also added an additional stressor, increased levels of nitrogen in the water, an environmental pollutant resulting from agricultural runoff, urban stormwater runoff, wastewater from sewers and septic systems and other sources. EPA researchers Alana Hanson and her colleagues simulated all these plant stressors in the same research greenhouse and concluded that the effects of climate change and nitrogen runoff were likely to reduce the sustainability of salt marshes because the conditions made it more difficult for cordgrass to flourish. Without cordgrass, Atlantic coastal ecosystems would be as vulnerable as a sea turtle without its shell.

On the other side of the country, researchers on the Pacific coast have been developing an approach to evaluate how climate change is affecting coastal biodiversity. Working with experts from several federal, state, and local agencies, EPA researcher Henry Lee and his colleagues developed an approach to use environmental tolerances and other scientific information to estimate how groups of species can be expected to respond to changes in ocean temperature and acidity. Their tool, the Coastal Biodiversity Risk Assessment Tool, or CBRAT, provides an open-source platform that allows researchers and resource managers to examine the potential vulnerability of coastal Pacific fish and invertebrate species as they are impacted by climate change.

These research efforts help us understand more than just the impacts of climate change on coastal ecosystems—they also help us understand how we can respond to those changes in ways that will help protect them. Francis Bacon is credited with the saying, “The best part of beauty is that which no picture can express.” Although we see the natural beauty of our coasts and shores, the best part of that beauty may well be the unseen ways in which they nurture and support nature as a whole.

From Grasslands to Forests, Nitrogen Impacts all Ecosystems

By Ashley Mayrianne Jones

Can there be too much of a good thing?

That’s the case with nitrogen, an essential element for plant growth that, in overabundance, can also be potentially damaging. Nitrogen moves from the air to the land, soil, and water via a process called nitrogen deposition. Atmospheric nitrogen deposition has increased ten-fold or more since pre-industrial levels due to increased emissions from the burning of fossil fuels, fertilizer use, and other human activities.

Blue Ridge Mountains at the Roan Highlands State Park in North CarolinaOnce nitrogen is emitted into the atmosphere, it can travel vast distances and deposit in the environment, making it a national as well as local problem. Elevated nitrogen deposition can increase leaf biomass in the canopy, shading ground-dwelling plants from the sun. Additionally, physical and chemical reactions that occur when nitrogen compounds are deposited can lead to more acidic soils. Both effects restrict plant growth and increase competition for limited resources, resulting in a loss of local biodiversity.

To date, most U.S. biodiversity studies on the effects of nitrogen deposition had been focused on individual sites, where fertilizer was applied and small plots were monitored through time. It was unknown whether the resulting reductions in plant biodiversity at these small scales translated to meaningful changes at the landscape level. A series of recent studies had indicated that across the European continent, many ecosystems were experiencing reductions in plant biodiversity due to nitrogen deposition. However, it remained unclear whether the same held true in the U.S., which historically, has experienced lower atmospheric deposition levels.

That’s why EPA researcher Chris Clark and a team of scientists from EPA, U.S. Geological Survey, the U.S. Forest Service, the University of Colorado, and multiple other universities are exploring the effects of nitrogen deposition on herbaceous plants (those with non-woody stems such as grass) in a first-of-its-kind study focused on multiple ecosystems across the nation. The new research expands the focus to not only grasslands, but into habitats that have not received much attention, including the forest understory.

The study, recently published in Proceedings of the National Academy of Sciences, assesses how nitrogen deposition affects herbaceous plants at over 15,000 forest, woodland, shrubland, and grassland sites throughout the United States. The research addresses how physical, chemical, and climatic factors such as soil acidity, temperature, and precipitation can affect an area’s vulnerability to nitrogen deposition.

Nearly a quarter of the sites were vulnerable to nitrogen deposition-induced species loss, and those with acidic soils tended to be more vulnerable. At extremely low levels of nitrogen deposition, the number of individual plant species tended to increase. However, above a certain threshold level, or “critical load,” diversity began to decline.

The study indicated that on average, forests can tolerate slightly higher levels of nitrogen deposition than other ecosystems before showing a negative impact on biodiversity. The reasons for this are unclear, but scientists hypothesize part of the reason is that forest species living under the canopy are already adapted to low-light conditions and are less susceptible to shading effects caused by increased nitrogen. Both grasslands and forests, however, were quite vulnerable to nitrogen deposition, with critical loads in the range of current deposition levels.

Moving forward, EPA scientists and their partners will attempt to determine which individual plant species are most at risk, and which native and invasive species may increase with elevated nitrogen deposition.

Examining multiple ecosystems across the country gives us more information about how different locations may respond to the effects of nitrogen deposition and will help set monitoring and conservation priorities that protect plant biodiversity.

Gamify the Grid! New EPA game Generate! Helps Students Understand the Relationship between Climate Change and Energy Production

By Rose Keane

When you’re teaching someone, sometimes you never know what’s going to stick. Some people need to hear the information, others might need to read it, but chances are the best way to get someone to remember is to have them try it themselves.

EPA researcher Rebecca Dodder is helping teachers provide middle school and high school students with these kinds of opportunities through her new Generate! game, a board game that requires the player to consider the costs and benefits of the type of energy we use and impacts on air quality and climate.

Hands-on learning! Kids play the Generate! game during Earth Day festivities at EPA’s campus in Research Triangle Park, N.C.

Having students actually grapple with the realities of financial limitations, carbon emissions, and limited natural resources makes the lesson much more tangible and long lasting. I had the chance to see these connections being made when students came to EPA’s campus in Research Triangle Park, N.C., to play the game during Earth Day festivities.

Here’s how it works.  In the first round, students select which sources of energy—for example, coal, natural gas, nuclear, solar or wind—that they would like to use given a finite amount of resources (in this case the number and types of energy pieces). Each energy source comes with its associated installation and maintenance costs, and the aim is to meet energy demands (filling up the full board space) while spending as little as possible.

The second round, however, made things a bit trickier. As with our energy sources in real life, there is a cost associated with the carbon emissions of each energy piece, with heavier costs for higher carbon-emitting sources like coal, and smaller or no carbon costs for the renewable energy sources. These costs refer to the idea that for each ton of carbon dioxide emitted, there are increased costs to communities from climate change. As students factored these numbers in, they realized their original plan was no longer sustainable and also way too expensive. You could practically hear the groans coming from each group’s table when the final tallies came in.

In the third round, students were offered pieces called “efficiencies,” which represent our behaviors, consumer choices, and energy efficient appliances. These pieces incur relatively small costs initially (for example, how much it would cost to replace your washer and dryer), but in the long run actually save the player money. “Think about it,” Dodder said to the students, “A lot of these big decisions are out of our control, like whether or not to build a nuclear power plant, for example. The thing about the smaller energy efficiency pieces is that’s all the stuff that we can change – it’s all in our control.”

Making climate change and its impacts tangible for younger generations can be extremely difficult, but games like Generate! make these kinds of activities fun, educational, and remind the students that their energy choices are in their hands. Educators can use this game to help their students recognize the relationships between energy usage and climate change, and encourage them to investigate their role in the carbon cycle further.

Dr. Dodder’s innovative approaches to educating the younger generation about science and her research contributions are being recognized today at a ceremony in Washington, DC where she will receive a Presidential Early Career Award for Scientists.

Particulate Matter in a Changing World: Grants to Combat the Impacts of Climate Change

By Christina Burchette

There are certain things that are always changing: the weather, fashion trends, and technology (which iPhone are we on again?) are a few that come to mind. I can always count on the fact that these things won’t stay the same for long. But there are other things that I typically expect to remain the same: I expect to get hungry around lunchtime, I expect the bus to come every morning, and I expect to be able to breathe clean air. I don’t even think about the possibility of these things not happening—until something changes.

I definitely don’t think about air quality often or expect it to change. As long as I’m breathing and well, why would I? But in reality, air quality changes every day, and over time it may change a lot depending on how we treat our environment—and we need to be ready for these changes. This is why EPA recently awarded research grants to 12 universities to protect air quality from current and future challenges associated with climate change impacts.

Climate change is affecting air quality by influencing the type and amount of pollutants in the air. One type of pollutant present in our air is particulate matter, or PM. Long-term exposure to PM is linked to various health effects, including heart disease and lung function, and it doesn’t take a high concentration to affect our bodies. The more PM there is in the air, the more likely we are to be affected by health conditions.

With EPA Science to Achieve Results (STAR) grants, university researchers are approaching the future of air quality from multiple angles with a focus on learning more about the PM-climate change relationship. They will study the impacts of increased wildfire activity that generates PM, often called soot, in the Rocky Mountains. They will look at the impacts that climate change and land use change have on the development of dust storms in the West and Southwest; and they will evaluate the best means of energy production in California where air quality is among the worst in the nation to reduce health care costs and lower levels of PM and greenhouse gases.

Over the next few decades, climate change will be the catalyst for various environmental trends, so finding a way to manage the impacts of these trends is essential to protecting our health. The work these grantees do will help to inform air quality managers and others to make sustainable and cost-effective decisions that keep our air quality at healthy levels and protect public health and the environment. That way, future generations will think of good air quality as something we can expect.

Air Quality Awareness: A New Generation of Research

By Dan Costa, Sc.D.

Graphic of clouds and buildings in a silhouette cityscape. It’s Air Quality Awareness Week! This week, EPA is showing how we care about the air by announcing grants to three institutions to create air research centers. We now understand more than ever about the threats of air pollution to environmental and human health, but there is still more to learn. EPA has a history of supporting research and development that complements the work of our own staff scientists to bolster scientific knowledge about the effects of air pollution. EPA uses this knowledge to address many pressing questions and understand connections between our changing environment and human health.

Since 1999, EPA has funded three rounds of research centers through a competitive grant process. The scientific experts at these centers have contributed to a more complete understanding of the persistent air quality challenges that continue to face our nation. The first round of EPA funded air research centers focused on particulate matter and examined the link between particulate matter and cardiovascular disease. In 2005, the next round of centers focused on whether differing health effects could be linked to specific sources of air pollution. By 2010, it was clear that to get an accurate understanding of real life exposures, we needed to examine the health effects of exposure to multiple pollutants at once instead of just one or two at a time. The third round of centers took on this complex challenge. The next step is to delve into questions regarding how the health effects of air pollution may vary in different cities and regions across our country – each with its own unique characteristics and set of pollution sources.

This leads us to today and our exciting announcement–EPA is awarding $30 million through its Science to Achieve Results (STAR) program to fund the establishment of Air, Climate, and Energy (ACE) Research Centers at Yale University, Harvard University and Carnegie Mellon University. These Centers will consider changing energy production methods and local climate, while investigating the effects of global climate change, technology, and societal choices on local air quality and health.

I am eagerly anticipating the many new tools and ideas that will be produced by this next generation of EPA funded air research centers.

When Cooking Can Harm: Cookstove Research and Human Health

By Dina Abdulhadi

Two researchers examine a clean-burning cookstove design in a lab.

EPA cookstove research

While I don’t Instagram every meal, cooking is still an important part of my life. It’s a social anchor that ties me to my family and friends. I also see the act of cooking as a major part of being healthy, since it allows me to control what goes into my food.

So when I learned that the process of cooking is one of the greatest health threats that people face globally, I felt disoriented. Cooking is an everyday task that most in the U.S. can accomplish by turning a dial on a stove. Yet three billion people throughout the world use biomass or coal-fed cookstoves to cook their meals and heat their homes, and the smoke from these fires often causes respiratory and heart disease. In fact, household air pollution is the fourth highest risk factor for disease worldwide for all genders and the second highest risk factor for women[1]. Cookstove emissions also contribute to climate change.

Recently, I attended a scientific meeting to learn about cookstove studies by researchers who received one of six grants from EPA to research cleaner technologies and fuels for cooking, lighting and heating in homes that have limited or no access to electricity or gas lines. This research into cleaner cooking options will help improve air quality and protect the health of people throughout the world, including native peoples in Alaska and others in rural areas of the U.S. who use cookstoves to make their meals.

A presentation by Dr. Tami Bond, one of the grantees and a professor at the University of Illinois, particularly stood out for me. Bond studies the climate and air quality effects of fuel combustion. She receives assistance from trained citizen scientists in the communities who help collect and assess emissions from cookstoves in their homes.

The research by Bond and other grant recipients has given me an appreciation for how science can help to provide solutions to environmental health risks, including those from simply cooking a family meal. I plan to learn more by visiting the cookstove research lab in Research Triangle Park, N.C. There, researchers are testing a wide variety of cookstoves from all over the world to measure their energy efficiency and how much they pollute. You too can get an inside look at the research by watching this recent video by Voice of America on EPA’s cookstove testing.

Climate Change and Extreme Events Research Showcased at American Geophysical Union Meeting

By Dr. Michael Hiscock

Derechos. Blizzards. Polar vortexes. Superstorms. Whatever you call them, you’re probably aware of the extreme weather events that have occurred with increasing frequency the past few years. What you may not be aware of is their complicated relationship with climate change, air and water quality.

Although science will probably never be able to pinpoint the specific cause of any extreme weather event, there is rising evidence that human-caused climate change is increasing the probability of future such events. This will have astounding societal and environmental impacts, as climatic and meteorological extremes can affect the hydrologic and atmospheric processes that in turn impact water availability, and water and air quality for people around the world.

This week, at the American Geophysical Union’s (AGU) Fall Meeting, I had the pleasure of convening a technical session focused on the complex interaction between climate change, extreme events, air and water quality. The session, Extreme Events and Climate Change: Impacts on Environment and Resources, was the largest global environmental change session at the meeting, and featured scientists and research teams from 20 different countries. Over two days, we saw more than 70 presentations on how climatic and meteorological extremes have changed and what their impact on resources and the environment will be.

In 2011, EPA released its first grant solicitation (“Request for Applications,” or RFA) to support research exploring the topic of extreme events and climate change. The request, Extreme Event Impacts on Air Quality and Water Quality with a Changing Global Climate, sought research proposals designed to provide the information and capacity needed to adequately prepare for climate-induced changes in extreme events, in the context of air and water quality management. We were looking to support research institutions that demonstrated the ability to develop assessments, tools and techniques, and demonstrate innovative technologies to achieve that.

The 14 institutions we supported, all of which presented at the above mentioned session, are currently seeking to better understand extreme events and establishing ways for climate scientists, impact assessment modelers, air and water quality managers, and other stakeholders to co-produce information necessary to inform sound policy in relation to extreme events and their impact on air and water quality within a changing climate.

The session provided an international networking event for top researchers to showcase their results: to better understand how local and regional extreme events will change in the future; to identify the impacts of extreme events on local and regional
water and air quality; and finally, how to disseminate the information effectively to stakeholders. Collaboration opportunities like this one will lead to comprehensive analyses of extreme events to better form sound policy for preserving and improving air and water quality and protecting human health for generations to come.

Clean Cookstoves Research: An Opportunity to Benefit Billions

By Bryan Bloomer, Ph.D.

I have long appreciated the ability to cook and heat my home with minimum risk of exposure to toxic indoor air pollution. But I am also painfully aware that more than 3 billion people around the world rely on inefficient, unsustainable and dangerous cookstove technologies for their everyday cooking, heating and lighting needs.

EPA’s Bryan Bloomer examines clean-burning prototypes at the Cookstoves Future Summit in New York City.

That is why I am so pleased to join EPA Administrator Gina McCarthy and other prominent leaders this week at the first ever ministerial- and CEO-level Cookstoves Future Summit, “Fueling Markets, Catalyzing Action, Changing Lives,” in New York City.

Traditional cookstoves typically burn biomass fuels such as wood, dung, crop residues, charcoal or the fossil fuel, coal. This causes a wide range of negative health effects to the people, primarily women and children, exposed to the smoke they emit. And there’s more. The use of traditional cookstove technologies also depletes natural resources, contributes to deforestation, and releases harmful pollutants into the atmosphere that contribute to climate change at regional and global scales.

This is why clean cookstoves research is a top EPA priority. Our goal is to transform the sustainability and health impacts of the energy infrastructure in ways that will not only improve the health of billions, most of them disadvantaged women and children, but improve the global environment as well.

We conduct and support cooperative research to identify gaps and deliver practical solutions from a wide array of stakeholders. The Agency is leading an international clean cookstove research effort, helping to support the development of international cookstove standards, conducting trusted independent research on the energy efficiency and emissions of cookstoves, and improving our understanding of the negative health impacts from exposure to cookstove smoke.

In March 2012, EPA announced the funding of six universities to address residential burning and its effects on human health worldwide. This group of researchers is developing innovative technologies to quantify the impacts of cookstove emissions on climate and air quality.

Moving forward, we and our many partners in this global effort will focus on translating these results into the field, primarily bringing innovative, consumer-driven and life-saving technologies to individuals worldwide.

Turning research results into welcomed solutions is the topic of this week’s Cookstoves Future Summit. The summit presents a unique opportunity to further develop a thriving and sustainable clean cookstove market. Such a market will mean substantial progress toward preventing the more than 4 million estimated indoor air pollution related deaths due to traditional cookstoves and fuels.

The clean cookstoves challenge encompasses a number of health, social and environmental issues. Such a pressing and compelling problem presents us with a significant opportunity to improve livelihoods, empower women and protect the environment for generations to come.

Preparing to “Move:” EPA Research Supports Taking Action on Climate Change

Climate change march in New York City, September 21, 2014.

The issue of climate change is generating a lot of headlines again this week. The “People’s Climate March” in New York City, followed by the Climate Summit at the United Nations are sparking renewed interest in “taking action on climate change,” echoing the White House’s Climate Action Plan that President Obama released last summer. To lend our voices to the chorus, it’s also Climate Action Week here at EPA.

As a researcher working on climate change, I’m hopeful that such events, coupled with people’s own personal experiences, mean we are moving beyond the old “discussions” about climate change that have played out in the media by what seem to be a gang of professional arguers.

More and more people are experiencing higher temperatures, heavier downpours, rising sea levels, longer droughts, and bigger wildfires—all impacts that scientists have expected as the climate changes. Even though we can’t say for certain that any one of these is caused by climate change (see my previous post, What Does Climate Change Have to do with Weather…and Baseball?), taken together they provide increasingly strong evidence that the climate is changing and we need to prepare. And people are beginning to respond in meaningful ways to the reality of climate change.

So how do we know how to prepare? A good analogy to me is my recent move across the country. The basic preparation steps are similar: I looked for information about our new location, talked with experts who move people for a living, and made plans. When I started the actual process, I packed things one or two at a time, thinking about what I had to pack last and unpack first. It’s the same with preparing for climate change. We look for information and talk with experts, and then we make plans. We take actions one at a time, keeping in mind how those actions will affect other actions and don’t try to do everything at once.

Taking action on climate change is big news.

EPA’s researchers are among the many people studying how climate change is affecting our environment to provide information to those who are making decisions. We study how rivers and coasts will change, and provide that information to towns, cities, states, and tribes so they can decide how they want to prepare for those changes and ensure their local communities will be resilient and healthy. EPA is doing research so we will continue to have healthy air as summers get hotter and drier. And we are working to develop the information needed by local water treatment facilities to deal with extreme rainfall events, so that our drinking water stays clean.

Knowledge, plans, and informed actions—these are at the heart of Climate Action Week. EPA science works behind the scenes to provide the knowledge people need to prepare for climate change and its impacts, so communities will have the best information possible to take action as they prepare their move into the new conditions brought on by our changing climate.
