Recreational marijuana is now officially legal in Minnesota but this may not be great news for the climate.

A 2021 study found that growing an ounce of marijuana indoors can result in greenhouse gas emissions equal to burning a tank of gas.

So as the cannabis industry continues to expand, how can it reduce its massive carbon footprint?

Ari Seaman is CEO and founder of OG AG TECH as well as COO of C4. He shared a new technology he’s developed to help farms become more sustainable.

The heat is on for Minnesota this week and heat waves are making news across the world.

Hospitals in Phoenix are treating burn patients from sizzling pavement. Tourists in Greece are evacuating fire zones.

How can scientists gauge when heat events are normal and when they’re fueled by climate change?

Climate Central chief meteorologist Bernadette Woods Placky talks about a tool she uses called the Climate Shift Index.

Climate change is putting stress on the traditional spruce and pines in Minnesota’s northern forests — and there’s real concern about their future.

So, researchers are planting trees from the southern parts of our state in hopes of saving our northern forests.

It’s called assisted migration and University of Minnesota professor Julie Etterson is studying if it can be an effective strategy for reforesting and fighting climate change.

How can your home be a weapon in the fight to reduce climate change?

One of the biggest opportunities for reducing greenhouse gas emissions is weatherizing and super insulating existing homes and buildings.

And lawmakers this year set aside a big chunk of money to help people do just that.

Tina Clarke has super insulated her own homes and helped others do the same. She shared her tips on how to get started.

As climate science and impacts evolve, how much should students in Minnesota and across the U.S. learn about climate change causes and solutions?

Kristen Poppleton is the senior director of programs climate generation in the Twin Cities, an organization that works with educators and students on climate change education in schools.

A “constitutional right to a clean and healthful environment”.

That’s why 16 young people between ages 5 and 22 are suing the state of Montana seeking a transition to a less carbon-intensive energy policy.

The trial has been called historic in Montana and could have implications nationwide on climate litigation.

Amanda Eggert has been following the case for the Montana Free Press and she shared her reporting with Climate Cast.

Earth’s oceans are the hottest on record. That’s the finding from a recent paper in the journal Advances in Atmospheric Sciences. What effects could this have globally and in Minnesota?

It’s said that water is life and trying to control and store water through massive dam projects has been a way of life for a long time, especially in the western U.S.  

But it turns out dams emit greenhouse gas and can have environmental impacts. Just how much do they emit and why are some rivers better off left to flow naturally? 

Stephen Hawley, author of Cracked: The Future of Dams in a Hot, Chaotic World, discusses what a world without dams could bring.

The search is on for an electric vehicle with a 1,000-mile range. And a new dime-sized battery may be a step in that direction.

Mohammad Asadi is a chemical engineer at Illinois Tech who was one of the people behind the discovery. He spoke with Climate Cast host Paul Huttner about the new technology and other potential uses for it.
