Overview:
- Southeast Michigan faces frost warnings with overnight lows in the 30s through the weekend, while northern Michigan deals with both frost and river flooding.
- The EPA's research office has been reduced from 1,500 scientists to 124, eliminating decades of independent public health research on air pollution and climate change.
- Blue-spotted salamanders are migrating through Marquette County, prompting park road closures and a citizen science photo project that has collected over 357 images.
🗞️ Frost warnings, possible snow, flooding: Michigan’s spring takes harsh turn A stretch of unseasonably cold nights will bring frost and possible freeze conditions to Michigan and neighboring Ohio through the weekend. The National Weather Service issued a frost warning for southeast Michigan, including Metro Detroit, with overnight lows dipping into the low-to-mid 30s Thursday through Saturday. A 20%-30% chance of light snow is also possible. Northern Michigan faces a dual threat, with frost combining with lingering flooding along rivers including the Rifle. 📌 Source: The Detroit News
🗞️ The EPA’s brain trust is gone. Scientists say America will pay the price. The EPA’s Office of Research and Development, which for over 50 years studied health threats from air pollution to climate change, has been effectively dismantled. Of more than 1,500 scientists, only 124 remain — and they face reassignment away from independent research. Critics warn the gutting eliminates the firewall between science and political appointees, undermining public health protections. The Trump administration defends the restructuring as improving scientific efficiency. 📌 Source: The New York Times
🗞️ It’s walleye season on the Detroit River The Detroit Riverfront is packed with anglers during the annual walleye run, which draws fishing enthusiasts from late April through May. The Detroit River offers walleye, muskie, perch, catfish and sturgeon, making it a globally popular fishing destination. The Detroit Riverfront Conservancy is hosting Riverfront Fishfest on May 2 at William G. Milliken State Park, inviting kids to learn fishing from experts and interact with sturgeon, which locals call “living dinosaurs.” 📌 Source: WXYZ-TV
🗞️ What’s flying over Lake Superior after dark? Whitefish Point Bird Observatory in Paradise, Michigan is tracking nocturnal bird migration for the first time in its nearly 50-year history. Michigan Audubon has installed five automatic recording units — housed in 5-gallon buckets mounted on tall poles — to capture night flight calls around the peninsula. The buckets filter out Lake Superior wave noise. Data will be collected across three migration seasons through 2028, focusing on songbirds and other species that remain poorly understood. 📌 Source: MLive
🗞️ Health, money benefits of Michigan’s Medicaid expansion at risk, researchers warn A University of Michigan study finds that Michigan’s Medicaid expansion has improved enrollees’ financial health alongside their physical health, reducing medical debt and boosting credit scores since 2014. But lead researcher Dr. Nora Becker warns those gains may be reversed. Starting in 2027, new federal work requirements and more frequent renewals could push eligible enrollees off the program — not because they don’t qualify, but because they don’t understand the new rules. 📌 Source: Michigan Public
🗞️ Marquette closes park roads so salamanders can cross in peace Blue-spotted salamanders are migrating through Michigan’s Upper Peninsula this spring, drawing public attention and a citizen science effort. Northern Michigan University’s Biology Department is asking Marquette County residents to photograph the 3- to 5.5-inch amphibians and upload images to iNaturalist, building a long-term dataset. Over 357 photos have been submitted so far. Marquette has closed Presque Isle Park to vehicles to protect the salamanders during their annual woodland-to-wetland journey. 📌 Source: Detroit Free Press/USA Today Network
