While it’s unclear just how snowy this winter will be, NOAA data shows that Minnesota winters have warmed more than five degrees on average since 1970. Warmer winters may cause more freeze-thaw cycles and increased road salt use. State maintenance engineer Jed Falgren spoke to MPR News chief meteorologist Paul Huttner about what MnDOT is doing to maximize road safety in a changing climate.

Last winter was the warmest on record in Minnesota — a perfect non-storm of conditions that included a strong El Niño combined with warming climate trends. But this year will be different thanks to a weak La Niña developing in the Pacific, said Kenny Blumenfeld, who tracks Minnesota's climate trends with the Minnesota State Climatologist office in St. Paul.

“People are going to love or hate this,” Blumenfeld said. “Our all-time record and seasonal snowfall was during a La Niña winter. And number three, which we just experienced in the 2022-’23 winter, that was 90.3 inches. That was a La Niña, too. You do tend to get a bit more snow, even in a weak La Niña compared to an El Niño type winter.”

The warming of the atmosphere plays a role in extra-snowy winters, Blumenfeld told MPR News chief meteorologist Paul Huttner. ”The warming of the planet obviously puts more water into the atmosphere, and that's one of the reasons that we're seeing the increased snowfall during the winter time.”

Minnesota is experiencing its fourth straight year of flash drought — and farmers are feeling the effects in their fields.

“Farmers and ranchers face unique challenges in a changing climate and experience climate related stress,” said Noah Fish, an agricultural reporter for Agweek.

“It’s not only their operations that are undergoing this change, but it’s emotional stress; these are farmers that are the ones out there working every day in these conditions.”

But grants offer relief, Fish said. The state of Minnesota is using federal grants to help farmers adapt to expanding droughts and a changing climates. Fish joined MPR News meteorologist Paul Huttner to talk about the kind of funding that is available to farmers and how it is helping.

Finding balance in life can be a challenge for everyone.

It can be especially hard to balance a life in climate work, politics and raising a family. That’s been Anna Farro Henderson’s experience, one she details in her new book “Core Samples: A Climate Scientist’s Experiments in Politics and Motherhood.”

Farro Henderson joins MPR News Meteorologist Paul Huttner to talk about the climate crisis and encouraging young women to enter the STEM field.

Minnesota’s climate continues to shift. The trend toward warmer winters and more erratic precipitation patterns continues.

“What we see globally and what we see right in our own backyards are the fingerprints of a warming world,” Heidi Roop, the Director of Minnesota’s Climate Adaptation Partnership, said.

She added that we should expect these extremes to continue.

“If we look out towards the end of the century, some of our future climate models show that our spring-time precipitation could be as much as 40 percent wetter and our summers around 20 percent dryer.”

She spoke more about Minnesota’s climate trends with MPR News Chief Meteorologist Paul Huttner.

Climate advocates are showing strong support for Gov. Tim Walz’s vice presidential campaign. They point to his record.

“Walz was responsible, or at least, signed into law several climate action bills that are progressive no matter which state you live in,” said Kristoffer Tigue, who wrote about Walz’s climate record for Inside Climate News. “That includes a law from 2023 which requires Minnesota utilities to produce 100 percent of their electricity from carbon free sources by 2040. He also signed several other bills that do a lot to advance the effort to slow down climate change.” 

Tigue joined MPR News chief meteorologist Paul Huttner to talk about Walz’s record in Minnesota and what that might mean for the Harris-Walz ticket.

“A lot of advocates and political analysts believe that the Harris-Walz ticket will probably walk a line that’s similar to what Biden has been doing in his last couple of years as president, which is taking kind of a moderate approach, trying to appeal to a broader audience, rather than appeasing a smaller, more progressive climate constituency,” Tigue said.

But there’s not a lot to go on.

“Both Walz and Harris have largely refrained from talking about climate change since announcing their campaign together, but in the debate with former President Trump earlier this month, Harris did address climate change, and the two have since released a platform, though the details on policy are still pretty slim,” she said.

A new report from the Global Carbon Project finds several sources of methane gas are on the rise.

Sahrah Kaplan, climate and science reporter for the Washington Post says the powerful greenhouse gas is “the fastest way to heat the planet and we’re doing that at an ever accelerating rate.”

Kaplan wrote about the Global Carbon Project report and joined Climate Cast to explain how agriculture as well as human influence are contributing to the rise in this potent greenhouse gas.

The State Fair gates are open – but there’s a noticeable absence in the Miracle of Birth Center: birthing cows and newborn calves. 

It’s all due to the spread of avian flu, also known as bird flu or H5N1. So how serious is the spread of avian flu, and what does climate change have to do with the spread of viruses between species? 

Izzy Ross is a climate solutions reporter for Interlochen Public Radio and wrote about the threat of bird flu spreading to dairy cows for Grist. Ross stopped by Climate Cast to talk about the link between bird flu and climate change.

Recent abundant levels of rainfall across the state have pulled Minnesota out of drought for the first time since June 2022.

Will this rainfall pattern continue? And how are Minnesota’s precipitation swings a symptom of climate change? 

Kenneth Blumenfeld with the Minnesota State Climatology Office talks about recent rainfall across the state and explains how both dry and wet patterns — sometimes lasting several months — are connected to climate change.
