What on Earth?

From cuts to U.S. weather agencies, to the rise of AI predictions, there are big changes in the world of extreme weather forecasting. We talk with the former head of the Canadian Hurricane Centre, about what it all means for our ability to warn Canadians before hurricanes hit. Then we hear how well the current AI forecasting models can predict these weather events — and how the technology needs to improve.

In 2023 Nova Scotia pledged to investigate how Black and Indigenous people in the province are disproportionately affected by pollution and environmental hazards, including climate change. As part of our "Best of What On Earth" series, we revisit our interview with the chair of the panel tasked with that work. Then we hear an update from one of the people who took part, who says the province is now withholding crucial information.

From the Best of What On Earth – It might not sound like a climate job, but mechanical insulators help make buildings more energy efficient. We head out to meet a young woman who trained in the trade through a program set up by the Youth Climate Corps BC. The group is training young people around British Columbia for a wide variety of good, green jobs and hopes to expand across the country.

Move the propane tank, clear the toys, replace the deck. When guest host Johanna Wagstaffe asks a FireSmart assessor for advice on safeguarding her home from wildfires, she’s left with a long to-do list – from simple to pricey. Then, we visit Canada’s first FireSmart community, Logan Lake, to hear how those efforts helped protect it from a mega fire. And we ask whether funding for wildfire prevention is keeping up with the growing risk.

After more than four decades of activism and advocacy, Suzuki is one of the most renowned and respected voices in the environmental movement. So when he says it's too late to stop climate change, people take notice. And that's now exactly what he's saying.

He's delivering this message as Prime Minister Mark Carney's government focuses on fast-tracking major projects it deems to be of national interest, which could include a new pipeline for fossil fuels from Alberta. Suzuki says that, despite his understanding of the climate crisis, Carney — like all of us — is trapped by the economic and political systems we've created. And for Suzuki, our only hope for survival is to scrap those systems entirely.

In this special episode from our colleagues at Front Burner, David Suzuki joins Jayme Poisson for a wide-ranging discussion from what a world of irreversible climate change looks like, to what he describes as the "madness" of continued investment in fossil fuels, to the lessons environmentalists of the future can take from the past.

From the Best of What On Earth – Wildland firefighters say working conditions threaten the safety of crew and the public in Alberta. People on the front lines say they’re losing team members to other employers that offer better pay, benefits and long-term opportunities – leaving what they call a gap in experience on the crews. In the midst of what is shaping up to be Canada’s second-worst wildfire season, we revisit our conversation. 

Planning to hit the road this summer? How about travelling 8,500 kilometres in an EV? That’s what Carl Duivenvoorden is doing on his zero emissions journey across Canada. He shares some of the tips he’s learned along the way, including the best and worst places for charging, and explains why EV road tripping is an efficient — and cheaper — option for the adventurous. After that, we’ll take a trip down the EV misinformation highway, in search of answers to common claims that electric vehicles aren’t really that green.

From the Best of What On Earth – Warming waters are threatening an irreplaceable species for Indigenous people in Canada’s north. But First Nations leaders in Yukon have become leaders in protecting and demanding better care for the Chinook salmon – a vital part of their traditional diets and culture. This story is a part of the Overheated series, put together with CBC Radio’s Quirks & Quarks and White Coat, Black Art to examine how heat is changing lives.

The Salinas Grandes in northern Argentina is home to large deposits of lithium, a key mineral in the fight against climate change. But Indigenous leaders in the region say mining the mineral could harm their water supply. We hear how communities are pushing back against potential lithium extraction. And, how new methods of mining are being tested - ways of extracting lithium that aren't so damaging to the local environment.

In the thick of the deadly flooding along the Guadalupe River, questions emerged about what could have been done differently. Republican politicians are pushing back vigorously, calling accountability questions “partisan games.” But one climate expert in the state says Texas needs to ask the tough questions right now before the next natural disaster hits – questions about the political power of fossil fuel industries and what that means for how politicians talk about, and prepare for climate change.
