In 2022, The State of Minnesota created their Climate Action Framework, a plan that sets a vision for how Minnesota will address and prepare for climate change. As of February 11th, the framework has been updated. MPR News chief meteorologist Paul Huttner spoke with Heidi Roop, the Director of the University of Minnesota Climate Adaptation Partnership, which helped create the new framework, to talk about the new changes.

NOAA data shows that winters have warmed more than five degrees on average since 1970. And last two years were some of the warmest on record, dating back to the late 1880s.But as the climate warms over decades, so do the 30-year averages for climate variables like temperature and precipitation. These new normals can mask the true magnitude of just how fast Minnesota is warming up.MPR News chief meteorologist Paul Huttner spoke with MPR News meteorologist Sven Sundgaard to explain how these normals can be misleading.

Minnesota’s prairie, in the southwestern part of the state, is a biodiverse ecosystem that’s home to buffalo, bees and tall grass. In the book, "Sea of Grass: The Conquest, Ruin and Redemption of Nature on the American Prairie," Josephine Marcotty and Dave Hage dig into the significance prairies have to the climate. MPR News chief meteorologist Paul Huttner talks with Hage in depth about the American prairie. The following has been edited for length and clarity. Use the audio player above to listen to the full conversation. What drew you to write about the American prairie?The book grew out of a series that Josephine wrote when we were both working with the Minnesota Star Tribune. She was the environment reporter. I was her editor. She had come across a pair of remarkable studies, which showed that today, we are plowing up the continent's remaining grasslands. That's grasslands west of here, into the Dakotas and Montana. We're plowing them up at the rate of a million acres a year. That's about as fast as we'r

The University of Minnesota’s Community Climate Leaders program connects students with actionable climate science, impact strategies, and a local network of peers. Christy Marsden, who oversees the program, joined Climate Cast to explain how community members can get involved in climate action.

Earth’s oceans continued to reach record-high temperatures in 2025. And those hotter oceans are fueling stronger and wetter storms.St. Thomas University researcher John Abraham, who reported these findings with his colleagues in the journal “Advances in Atmospheric Sciences,” joined Climate Cast to talk about how the latest research on Earth’s warmer oceans affects the people of Minnesota.

Beneath the harsh winds and temperature of Antarctica, scientists have identified ice cores that give new insights into Earth’s past.Martin Froger Silva works with the National Science Foundation Center for Oldest Ice Exploration. He and a team of researchers have been drilling in Antarctica for ice millions of years old. Silva talked to Climate Cast host Paul Huttner about their research.

It’s not your imagination — the cost of your home insurance is going up. Weather-related extreme events have sent homeowners’ insurance rates skyrocketing. Federal budget cuts to the Federal Emergency Management Agency will exacerbate these issues, particularly affecting state budgets and risk reduction efforts. In Minnesota, homeowners insurance rates increased the last decade due to hail damage, leading to non-renewals and some companies leaving the market. Jordan Haedtler, a climate financial policy strategist with Climate Cabinet, based in Duluth, talks with MPR News Chief Meteorologist Paul Huttner about climate-change-fueled risks and steps the state Legislature is taking to address to address the issues.

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 forecasting model that uses AI to improve local flood predictions.

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, I think it tells a narrative of the direction we’re going as a state.”Tigue explained that the state is experiencing warmer winters, an increase in precipitation and melting. Tigue wrote about the many ways Minnesotans are seeing climate change — from warmer falls, to a lack of foliage color and wildfire smoke.

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 above to listen to this episode or subscribe to the Climate Cast podcast.

Minnesota has a goal to move toward 100 percent carbon-free electricity by 2040.That will have significant impacts on certain parts of the state where coal plays a major part in the economy — like Itasca County.So, how are people in this part of northern Minnesota adapting?Itasca County Commissioner John Johnson spoke about how the county is planning for the transition.Click play on the audio player above to listen to this episode or subscribe to the Climate Cast podcast.

It was another beautiful fall color season in Minnesota, and we know seasonal temperature change is what drives our fall color show.But did you know those trees can react to more subtle microclimates around the state and even within your yard?Tyler Hesseltine is an arborist who works with trees all year long. He talked to Climate Cast host Paul Huttner about how even small landscaping decisions can have a big impact on tree health.

Minnesota may be a long way from the ocean, but we have great seafood options.So, how can we choose and prepare seafood that’s delicious and climate sustainable?A new cookbook called “The Blue Food Cookbook: Delicious Seafood Recipes for a Sustainable Future” has some ideas.Minnesota native and four-time James Beard award-winning chef Andrew Zimmern co-wrote the book with seafood expert Barton Seaver.Zimmern shared tips and recipe ideas with Climate Cast host Paul Huttner.Click play on the audio player above to listen to this episode or subscribe to the Climate Cast podcast.

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 director for the Minnesota Pollution Control Agency, shared more about the framework and how people can get involved on this week’s Climate Cast.Click play on the audio player above to listen to this episode or subscribe to the Climate Cast podcast.

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 author of the analysis, and she shared more about the findings as well as solutions to offset the climate impacts of continuous corn with Climate Cast host Paul Huttner.Click play on the audio player above to listen to this episode, or subscribe to the Climate Cast podcast.

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 their winters and all of the places that they need to go between their summer and winter habitat.” MPR News meteorologist Paul Huttner talked with Schofield about warmer winters in Minnesota and how it’s disrupting summer and winter habitats.Click play on the audio player above to listen to this episode, or subscribe to the Climate Cast podcast.

Federal tax credits for solar projects are expiring at the end of this year, and some smaller towns in rural Minnesota have tapped into the benefits.For Climate Cast this week, MPR News meteorologist Paul Huttner talks to Minnesota Star Tribune reporter Kristoffer Tigue about the skepticism around solar power that many small and local governments had adopted over the years and the economic benefits that changed their minds.

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 degrees for September temperatures, and we’ve had a lot more warmer than cooler Septembers since 2010.”MPR News chief meteorologist Paul Huttner talked with Boulay about the state’s fastest warming month and how it could impact fall colors.

New research indicates warmer oceans may change ocean currents and atmospheric patterns in a big way.In this episode of Climate Cast, MPR News chief meteorologist Paul Huttner continues his conversation with John Abraham of the University of St. Thomas about shifting currents in the Atlantic Ocean and the importance of measuring ocean temperatures.

Climate scientists have known about connections between oceans and the atmosphere for decades, but new research indicates warmer oceans may change ocean currents and atmospheric patterns in a big way. MPR News chief meteorologist Paul Huttner talked with John Abraham of the University of St. Thomas about shifting ocean currents in the Atlantic Ocean. The following has been lightly edited for clarity. Click play on the audio player above to listen to this episode, or subscribe to the Climate Cast podcast.This study finds a higher chance than previously thought that the Atlantic Ocean may see some big changes. What do we need to know here?There’s what's called a conveyor belt in the ocean, and this is water that travels up the East Coast of the United States and then goes toward Greenland, Iceland and Northern Europe. The water gets cold, sinks to the bottom of the ocean and then it travels backward. It sort of goes in a like a loop — or a conveyor belt. That passageway of water is really, really important beca
