2025/12/12

Climate change has amplified the hydrologic cycle in Minnesota. Our more erratic precipitation patterns are driving faster transitions from drought to floods. So, can AI-driven forecasts help predict floods on rivers like the Mississippi? “We need to make innovations in these sorts of models and in our flood forecasting in general,” said Zac McEachran, a research hydrologist from the University of Minnesota. McEachran talked with MPR News meteorologist Paul Huttner about a new flood

Climate change is reshaping Minnesota winters

2025/12/05

Weather data suggests Minnesota has warmed more than three degrees in the past 150 years, and the state’s winters have warmed more than five degrees since 1970.So how are Minnesotans seeing and feeling these climate changes? “Here in Minnesota, we are experiencing climate change predominantly in the winter,” said Kristoffer Tigue, a reporter for the Minnesota Star Tribune.“We base a lot of our culture around our winters, and so to have our winters being the season that's changing the most,

Minnesota winters are not what they used to be. The bone-chilling season has warmed more than 5 degrees on average since 1970. Those warmer temps have contributed to another weather phenomenon: more snow — even if it doesn’t seem that way.How do we explain that paradox? Climatologist Kenneth Blumenfeld tracks snowfall trends for the Minnesota State Climate Office. He explained the connection between snowfall rates and higher global temperatures on Climate Cast.Click play on the audio player

How should Minnesota approach climate change action in the years to come?Minnesotans can have a voice in that process by commenting on the state's latest proposed Climate Action Framework, a comprehensive plan laying out steps Minnesota should take to address climate change and reach a carbon-free future. The last framework was released in 2022 and established a statewide target to reach carbon neutrality by 2050. That framework was adopted into state law in 2023. Kate Knuth, climate

2025/10/16

Almost 15 million acres in the Midwest grow corn on the same land year after year. That’s about 20 percent of all Midwest cropland.Growing corn in this way produces more greenhouse gas emissions than crop rotation because it releases more nitrous oxide — a greenhouse gas 300 times more powerful than carbon dioxide.That’s according to a new report from the Environmental Working Group.But cost-effective, climate-smart practices can reduce these emissions in a big way.Anne Schechinger is lead

Warmer winters add challenges for migrating birds

2025/10/09

Seasonal migration is underway, and Minnesota's landscape is playing an important role in guiding birds down south.But milder winters across the state can impact the migration process, as well as disrupt food availability and breeding opportunities. “This [is] what we call migratory connectivity,” said Lynn Schofield, a biology instructor and staff biologist at St. Olaf College, “which is to connect all the dots between where the birds are spending their summers, where are they spending

Minnesota continues to bask in warmer temperatures, blurring our seasons together. “If you break it up month by month, the biggest change we've seen is Septembers,” said Pete Boulay, assistant state climatologist with the Minnesota State Climate Office. “September is evolving into an extension of summer.”Average temperatures for the fall season have been warming up about one degree a decade since 1970. “Averages used to be, statewide, about 55 degrees,” Boulay said. “Now we’re about 61

The jet stream, a fast-moving river of air thousands feet above Earth, steers storms and weather systems around the globe.Scientists have been studying how climate changes impact the jet stream for decades. Now, one study in the scientific journal Nature, discovered a jet stream behavior change.“The jet streams are shifting,” said Larry Di Girolamo, professor and climate researcher with the University of Illinois.

Fireflies across the U.S. have seen a robust surge in growth this summer in part to a wetter weather pattern. But those fiery little critters — which some call lightning bugs — might be in a steady decline. “Insect populations are known to vary from year to year,” said Eric Berger, a freelance journalist for The Guardian. “A one-year increase is not enough to indicate that there has been a reversal in the downward trajectory of fireflies.”Berger added that scientists do not have baseline

The Trump Administration has claimed that greenhouse gases don’t endanger people. And last month, the Environmental Protection Agency said it intends to rescind a landmark 2009 legal opinion — effectively ending all its climate regulations.This all comes on the cusp of a rapidly-warming planet fueling extreme weather events. A hotter planet poses an existential crisis on multiple fronts, said Alan Weisman, journalist and author of “Hope Dies Last: Visionary People Across the World, Fighting

2025/07/25

Minnesota’s clear, cool lakes are heating up over the summer, and those warmer waters can produce a toxic agal bloom.“Blue-green algae is bacteria,” said Kim Laing, a surface monitoring manager with the Minnesota Pollution Control Agency. “It often looks like pea soup [or] green paint; sometimes it might have a smell to it. It thrives in warm, shallow, nutrient-rich lakes.” Water that’s warmer than 75 degrees along with calm, sunny weather is a perfect recipe for blue-green algae, he said
