Far from grocery stores, this community built a greenhouse

Work is underway to pump seawater onto ice in Nunavut as a way to thicken it in the face of climate change. The experiment is showing some promising results but there are also concerns about its impact on ecosystems. Journalist Alec Luhn travelled onto the ice to see what was happening and to listen to local Indigenous elders about what the ice means to them. He also considers the moral hazard of trying to geoengineer a solution and whether it distracts from the real work needed to cut emissions.

Severe drought and a record-breaking wildfire season have left some remote First Nations in Manitoba cut off from the rest of the province. Planes were grounded by wildfire smoke, and in one boat-access community, the lake was so low the ferry couldn’t run. Now, demands from Indigenous leaders are growing for better all-season roads, so the next time climate-fuelled disasters hit, they can get their people out.  

The Biljik First Nation in New Brunswick is growing food aplenty thanks to a geodesic dome, community gardens and traditional knowledge. We pay them a visit during pumpkin harvest, to find out how they’re winning the fight for food security even as drought threatens the region. Then we cross the country to find out why one bumper crop season is worth celebrating , but also why it’s not enough in a changing climate. 

If you drove by recent rallies across Canada, you might’ve wondered: what are they protesting? War? Fossil fuels? Discrimination? There were placards about all of it. Our youth climate action columnist Aishwarya Puttur says banding together could strengthen, not dilute, activists’ messages. Then, we hear a similar call to action from renowned primatologist Jane Goodall, who died a few days ago at the age of 91.

Carter Vigh died when wildfire smoke brought on a severe asthma attack. Now his mom is part of an effort to teach other kids about the risks of smoky days and poor air quality. We hear the case for having these kinds of lessons in classrooms everywhere, as the planet warms, creating the hot, dry conditions that lead to longer lasting and more intense fires. And – we meet Roland, another nine-year-old kid with asthma, to find out how climate change is changing his life. 

Cori Lausen remembers the first time she saw a bat killed by a wind turbine. It looked like a “black banana peel.” That unlocked a years-long search to understand what was happening and how to fix it. Decades later, Cori says not enough has been done to keep those bat species, which act as natural pest control, from becoming endangered. As wind energy developments continue to pop up in a rush to add renewables to the grid, the question looms: will we be able to do enough to keep both climate solutions on the landscape?

Here’s a pitch for a national project that could bring cheaper power to Canadians, reduce emissions, protect our energy sovereignty and promote Indigenous reconciliation. How about a cross-Canada electricity grid powered by wind and solar? What On Earth’s Indigenous climate solutions columnist, Melina Laboucan-Massimo, is with a delegation in Ottawa making the case for why this project should be a priority for Mark Carney’s government.

The Yukon government is betting on a first-in-Canada solution to help protect Whitehorse from wildfire: a permanent fuel break made of trees. Replacing conifers with the more fire-resistant, deciduous aspen trees, the community hopes it will keep fire from encroaching on the city. But, the process takes a lot of work, starting with harvesting tiny seeds.

Bike lanes equals “bikelash” in parts of Canada. Why? And what is Paris doing right? We travel the path to the heart of the debate about making cities more bicycle friendly, finding out what difference they make to cutting emissions. Then we’ll hear about one Calgary man’s cycling adventure in Paris (croissants by the Seine anyone?) and what he learned about the city’s campaign to build better routes for bikes. We’ll also head to a neighborhood meet-up where one enthusiast is trying to teach the youngest to safely ride on Vancouver city streets in hopes of building a stronger cycling culture and community. 

They’re popping up on balconies across Europe. You can even buy them at IKEA in Germany. Solar panels designed to hang over a railing and plug into your wall. We hear about what’s driving the trend, and what’s standing in the way of bringing balcony solar to Canada.
