In certain parts of the U.S., the ability of residents to prepare for and respond to flooding is being undercut on three different levels.
Climate change is real. It is here. And it is influenced and accelerated by human activity, posing an ongoing crisis for natural ecosystems and communities worldwide. Researchers at the University of Michigan are continually seeking to better understand the inputs and predict the outputs of climate change, with a goal of better informing effective responses to its impacts. Through a multidisciplinary approach, U-M experts are building frameworks that produce local and short-term frameworks that can be applied in an array of different ecosystems worldwide, and in a way that is accessible to policy and business leaders as well as the general public.
In certain parts of the U.S., the ability of residents to prepare for and respond to flooding is being undercut on three different levels.
In a new long-term ecological experiment, researchers showed that elevated levels of carbon dioxide nearly tripled species losses in grasslands attributed to the long-term application of simulated nitrogen pollution.
This year’s survey will focus on critical topics including carbon neutrality, transportation, waste prevention, climate change, and food sustainability. New questions on climate anxiety will explore respondents' feelings about climate issues and their experiences with direct impacts.
U-M has received a $25 million grant from the National Oceanic and Atmospheric Administration to support collaborative research initiatives addressing critical environmental challenges in U.S. coastal communities.
While ticks and the maladies associated with these minute vampirish insects get a lot of media attention, lurking in the not-too-distant shadows we find several other and potentially more ominous vectors of disease—the fungal pathogens.
Despite ongoing geopolitical tensions, the United States and China have the opportunity to collaborate on reducing methane emissions, a critical greenhouse gas significantly contributing to about 30 percent of global warming.
The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere. But a unique experiment is showing that, on a warming planet, more carbon is escaping the soil than is being added by plants.
Anyone who’s spent their winter months around the Great Lakes has probably had the uncanny experience of living through three seasons in a single weekend. According to new research from U-M, these wild weather swings are poised to become even more common in the future.
For carbon capture and utilization (CCU), public support depends on which aspect of the technology is being considered and which people are considering it, according to a new study conducted by researchers from University of Michigan and other institutions.
Nanoparticles delivered intravenously in mice can block the allergic reactions to red meat caused by the bite of the lone star tick, new research led by U-M shows. The condition, called alpha-gal syndrome, is on the rise in humans as climate change and other factors have led the ticks to expand their habitat.
As climate-induced migration increases in the U.S. and elsewhere around the world, what are the potential policies to help communities adapt and support residents? In a new Core Conversations podcast, Kaitlin Raimi explores how Americans view climate migrants, how policies could become a crucial factor influencing climate migration, and what the broader impacts of migration may mean for American society and the economy.
People find it hard to resist negative messages. A recent U-M study reveals that recipients are more likely to engage with emails containing negative sentiment sent by the Environmental Defense Fund, a U.S. based nonprofit organization. Specifically, emails with a negative tone were more frequently opened, and recipients were more likely to click on links within these emails, compared to those with a positive tone.
As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research led by U-M scientists.
A recent University of Michigan study exposes a gap in sociology: a lack of focus on climate change. Societies fuel and face the consequences of this crisis, but sociology as a discipline appears insufficiently engaged with the issue, says Sofia Hiltner, U-M doctoral candidate in sociology.
“Clarity on vulnerable subgroups more susceptible to heat-related deaths will enable policymakers to design effective intervention strategies targeted to these subgroups. Downstream, this will ensure greater climate action equity.”
Currently the director of the Office of Energy Justice and Equity and the secretarial adviser on equity at the U.S. Department of Energy, and formerly the department’s chief diversity officer, Baker will advance sustainability education and research across U-M schools and colleges.
Great Lakes researchers at U-M have been awarded a $6.5 million, five-year federal grant to host a center for the study of links between climate change, harmful algal blooms and human health. Increased precipitation, more powerful storms and warming Great Lakes waters all encourage the proliferation of harmful algal blooms composed of cyanobacteria.
The U.S. National Science Foundation has awarded a three-year, $614,000 grant to U-M and its international partners to create a new research initiative that will address the socioeconomic vulnerabilities of climate migrants in the Lake Victoria Basin (LVB) and Great Lakes Region (GLR).
Three new U-M sustainability catalyst grants will support novel research projects to address vexing environmental challenges. “Catching the Waves” focuses on deploying wave energy converters to power remote coastal communities, starting with Beaver Island in Lake Michigan. “Mussel Roads” uses biomimicry to enhance asphalt durability by developing materials inspired by mussel-binding proteins. “Plast-ick,” leverages artificial intelligence and satellite data to predict pollutants like PFAS in water bodies.
Nearly half of the young people surveyed on disaster preparedness indicated they felt unprepared for any type of disaster event during a period when catastrophic climate disasters are becoming increasingly frequent, says a U-M researcher.
“Given that we sit in the heart of the Great Lakes and 21% of the world’s fresh surface water, we wanted to explore the region’s plans to identify the highest-impact, most innovative and scalable multi-state opportunities. We looked for what was working, to inform ways to accelerate community-based climate action."
As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one U-M scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.
One of the most important things people can do to address climate change is talk about it, climate scientist Katharine Hayhoe said. Citing statistics that two-thirds of people in the United States are worried about climate change, but only 8% are activated to do something about it, Hayhoe said talking about climate change doesn’t mean trying to change the minds of those who believe it is a hoax.
A new study published online April 4 in the journal Science finds that agricultural diversification comes with significant benefits, and very few negative effects.
The ice-out, declared on March 16 this year, comes after the latest-recorded Douglas Lake “ice-in” occurred on Jan. 6—making this the shortest season of lake ice cover recorded at the U-M Biological Station, at 70 days. For 93 years, scientists at the Biological Station, the 10,000-acre research and teaching campus nestled along Douglas Lake near Pellston in the northern Lower Peninsula, have made the calls based on their observations of the lake.
Pollen allergies affect nearly one third of the global population, and climate change is set to make it worse. Rackham student Yingxiao Zhang is developing a better way to forecast allergy season to help people better navigate its headaches.
U-M is marking late March and all of April with a series of events focused on sustainability and climate action, continuing a tradition that began with the first “Teach-In on the Environment” in 1970—which grew into what is now known as Earth Day.
“I think we’ve become more and more aware of that as a problem, and it’s tearing down Americans’ trust of their own country and their government, because they feel like the game is rigged. And if we want to try to restore some trust in the system, we need to unrig it."
"Train travel in America is much more limited than, for example, in Europe. You often can’t get where you want to go. But you can get to Lincoln from Ann Arbor, with just one change in Chicago. What’s the carbon savings? A flight to Lincoln would add about 800 kg of CO2 emissions to my annual budget. The train trip is more like 85 kg. Takes more time, for sure, but that’s a big part of why emissions from train travel are so much lower."
When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. But U-M scientists are looking at something a little more tangible: coral.
The global challenges posed by climate change are widespread, impacting various aspects of human life, with water resources at the forefront of these challenges. As climate change advances, it is projected to exacerbate water scarcity and access issues, given the intensification of water-related hazards (such as hurricanes and flooding) and rising temperatures that will lead to sea-level rise and saltwater intrusion.
The ClimateCAP MBA Summit, a conference that aims to prepare future business leaders on how to understand and respond to the climate crisis, was hosted at U-M this year.
Rackham Ph.D. candidate Etienne Herrick-Sutton works with Great Lakes region farmers to identify strategies for improving the environmental and economic outcomes of cover cropping.
Six new research projects will investigate the shifting dynamics of harmful algal blooms, economic trends in coastal communities, emerging fish viruses, and other issues relevant to the Great Lakes.
As the architect of the Solar Energy Research Institute, which won 42 awards and was named the most energy-efficient building in the world, Rich von Luhrte knows how something is built is just as important as what is produced and why. That knowledge and his passion for addressing climate change have led him to establish a scholarship supporting students studying urban design.
Scientists have long warned that a warming climate will cause communities around the globe to face increasing risks due to unprecedented levels of flooding, wildfires, heat stress, sea-level rise and more. Though the science is sound—even showing that human-induced, climate-related natural disasters are growing in frequency and intensity sooner than originally anticipated—climate change is still not wholly accepted as true in the United States.
“Often we look at climate change or widespread human poverty or these deep inequities that hold so many communities back generation after generation, and we say to ourselves, these challenges are too complex. I’m just one person; what can I do to really make a difference?”
The United States recently passed major climate change laws, such as the Infrastructure Investment and Jobs Act (IIJA), the Inflation Reduction Act of 2022 (IRA), and the CHIPS and Science Act, which allocate funding with a goal of expanding energy-transition initiatives. Analysts suggest new investments could reduce greenhouse gas emissions by more than 40% below 2005 levels by 2030.
This winter, researchers at the U-M Biological Station in northern Michigan are strengthening their snow science with new technology to track the snowpack at an hourly rate and get a deeper understanding of the complexities of global environmental change.
Four newly awarded sustainability “catalyst grants” at U-M are piloting innovative ways to bolster climate resilience and sustainability. Funded by the U-M Graham Sustainability Institute, these projects will explore renewable energy deployment in Nepal, climate justice in the Midwest, textile recycling innovation and equitable transportation planning.
Climate change is reshaping forests differently across the United States, according to a new analysis of U.S. Forest Service data. With rising temperatures, escalating droughts, wildfires and disease outbreaks taking a toll on trees, researchers warn that forests across the American West are bearing the brunt of the consequences.
"“And the warming will continue to accelerate until we halt the burning of fossil fuels. This means continued worsening extreme heat and heat waves, but also many other worsening climate extremes driven by warmer temperatures. More severe droughts, more intense rainfall, more devastating hurricanes and bigger, more widespread wildfires."
Concern for climate change grows—along with support for policies to reduce emissions—when people read about Americans being forced to move within the U.S. because of it. That’s in sharp contrast to learning about climate-induced moves to the U.S. by non-Americans, which doesn’t move the dial on climate change beliefs or policy support.
Rackham student and sociologist Joyce Ho’s research seeks to understand homeowners’ experiences and insurance companies’ responses in the aftermath of forest fires in northern California.
At the COP28 climate summit in Dubai, nearly 200 nations approved a global pact that calls for transitioning away from fossil fuels—a first. The deal also calls for tripling the use of renewable energy, doubling energy efficiency and slashing methane emissions.
