As climate change becomes more pronounced, so too does the size, impact, and prevalence of extreme weather events. University of Michigan specialists are examining ever-increasing natural disasters, the upheaval they wreak on impact communities, and how local authorities can better manage them. U-M researchers have focused on extreme weather that ranges from regional events, like Great Lakes flooding and polar vortices, to droughts, hurricanes, wildfires, and tsunamis that carry a global toll.
Earliest recorded ‘ice-out’ date on Douglas Lake at U-M Biological Station in northern Michigan
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.
U-M ‘catalyst grants’ address climate resilience, sustainability
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 threatens global forest carbon sequestration, study finds
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.
2023 warmest year on record
"“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."
Climate disaster: When the smoke clears
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.
Lewis on the future of climate resilience in “haven” cities
Ann Arbor and other cities across the Midwest and Northeast have been referred to by climate specialists as “climate havens,” natural areas of refuge that are relatively safe from extreme weather events such as intense heat and tropical storms.
Air pollution a long-term risk for low-income countries' prosperity
"In many parts of the world, the air pollution monitoring network is inadequate, so people just don't know how bad pollution is in their neighborhoods. And even when they have a monitor nearby, households might not be aware of the full range of health damages that they could be experiencing. So people don't always take adequate measures to protect themselves."
UMSI launches theme year on water conservation and access
“Water conservation and access” brings a slew of images to mind: wastewater flowing through main lines to a city treatment plant, a fisherman yanking invasive mussels off the hull of a trawler, the installation of filters in communities that lack access to safely managed drinking water.
U-M-led team receives $7.5M to predict, communicate flood risk
The devastating floods that ripped through the northeast United States are among the most recent in a long string of severe flooding events occurring worldwide, which make it plain that better flood predictions and safety plans are needed. According to the Organization for Economic Cooperation and Development, flooding causes $8 billion in losses on average annually in the U.S. alone.
Risk of death for people with dementia increases after a hurricane exposure
The risk of death rises among older adults with Alzheimer’s or other dementias in the months following exposure to a hurricane, a new U-M study shows. Their increased risk could be due to disruption of normal routine, such as access to caregiving, changes in living environment, loss in access to medications, and change in daily routines, said study first author Sue Anne Bell, assistant professor at the U-M School of Nursing.
New Carbon Neutrality Acceleration Program projects receive over $1M in funding
The Graham Sustainability Institute’s Carbon Neutrality Acceleration Program (CNAP) announced $1,160,000 in funding for six new faculty research projects. They tackle a range of carbon neutrality topics and augment the CNAP portfolio, which addresses six critical technological and social decarbonization opportunities: energy storage; capturing, converting, and storing carbon; changing public opinion and behavior; ensuring an equitable and inclusive transition; material and process innovation; and transportation and alternative fuels.
COP27 climate conference in Egypt: U-M experts available to discuss
Global climate talks in Egypt are heading into the home stretch with many issues still unresolved. Negotiators from nearly 200 countries have gathered in Sharm el-Sheikh for the COP27 conference in an effort to curb greenhouse gas emissions and avoid the worst ravages of climate change.
SEAS graduate student's project brings clean water to struggling communities
When an emergency causes a disruption in access to clean water, it seems reasonable to respond by providing the public with bottled water. In the short term, this can provide a safe supply of water while the problems get sorted out. But what if the emergency has lasted eight years, and counting, as it has in Flint, Michigan?
Creating equity in midwestern flood response and recovery
Flooding is the leading cause of property damage and deaths in the U.S. It’s bigger than earthquakes and forest fires put together. Branko Kerkez, an associate professor of civil and environmental engineering, and his students at the Digital Water Lab partnered with researchers at the U-M Center for Social Solutions to measure, better understand and prevent flooding and its aftermath in some of the most vulnerable communities.
When climate change hits home
Many small and mid-sized communities like Goshen, IN simply don’t have the resources to tackle a global crisis like climate change on their own. So in 2018, Goshen was one of 12 cities that partnered with Great Lakes Integrated Sciences and Assessments (GLISA), an organization led by U-M that’s working to help small and mid-sized cities plan for a future that will be shaped by a changing climate.
Climate change plus a third straight La Niña is not a good thing
"We can’t stop natural climate variability and the extreme weather La Niña can bring, so we must instead accelerate our efforts to stop the human-driven climate change that is relentlessly turning so many climate extremes into unprecedented disaster and suffering."
The West’s water crisis is worse than you think
"Water levels are getting lower and lower because of two big problems. First, the long agreed-upon annual allocation of water to about 40 million users in seven states (e.g., California) and Mexico exceeds the supply of water flowing in the river. Second, and ignored by many, the water flowing in the river is also dropping relentlessly, as a warmer, drier climate reduces the amount from snow and rain that reaches the river."
Examining the effects of flooding on Detroit residents' mental health
As a board member of the nonprofit Cass Community Social Services organization in Detroit, SEAS master’s student Isabella Shehab has seen firsthand the challenges the city and its residents face: vacant buildings, aging infrastructure, flooding. Now, Shehab is using a scholarship awarded through the Landscape Architecture Foundation (LAF) to research the impacts these challenges have on Detroit residents’ mental health and well-being—all with an eye on solutions.
Triple-digit heat is killing us and our economy: What to do?
"Our growing global warming and heat wave problem is scorching our economy in many ways, racking up a trillion-dollar-plus price tag in the U.S. alone. Impacts are often highest locally where extreme heat occurs, but global supply chains are also at increasing risk due to heat-supercharged extremes, including drought, wildfire, flooding and deadly storms."
Scientists reconsider the meaning, implications of drought in light of a changing world
Maps of the American West have featured ever darker shades of red over the past two decades. The colors illustrate the unprecedented drought blighting the region. In some areas, conditions have blown past severe and extreme drought into exceptional drought. But rather than add more superlatives to our descriptions, one group of scientists believes it’s time to reconsider the very definition of drought.
Gerber and Agrawal examine effects of human and social capital in disaster recovery
How do human and social capital affect people in the aftermath of a disastrous shock? Ford School professor Elisabeth Gerber and School for Environment and Sustainability professor Arun Agrawal examined the question with data gathered before and after the 2015 earthquakes in Nepal, using a novel machine-learning based analytical approach.
The southwest must fight for its water and its future
Without a sustainable water supply, life in the desert is all but impossible. Flows of the Colorado are steadily shrinking because it’s snowing and raining less in the headwaters. Even bigger reductions in river flow have occurred due to the impact of relentless global warming.
Wildfires, communities and climate change
Communities across the western United States face an existential crisis. As forests become drier and thicker with vegetation, and development encroaches further into forested areas, wildfires grow larger, more frequent and more damaging. U-M experts are working with practitioners across the west to address this growing concern.
Extreme heat and the ongoing aridification of the West
Something highly unusual is happening in the western United States. Record hot temperatures, some above 115 degrees Fahrenheit, recently spanned the Southwest northward into the interior West, and now a dangerous heatwave is hitting the Pacific Northwest. The news has been full of references to ongoing western drought and predictions of yet another extreme wildfire year. Even so, in reality, the story is worse.
‘Doomsday Glacier’ may be more stable than initially feared
The world’s largest ice sheets may be in less danger of sudden collapse than previously predicted, according to new findings led by U-M. Researchers modeled the collapse of various heights of ice cliffs—near-vertical formations that occur where glaciers and ice shelves meet the ocean. They found that instability doesn’t always lead to rapid disintegration.
