Eco-thugs be warned! You could be charged with ecocide

Seafarers of old saw kelp as a danger, marking it on maps to avoid it. Today those maps are helping to restore kelp as a friend of the climate. Kelp sucks in carbon so the Tseshat First Nation is working hard to bring it back around the Broken Group Islands in BC. 

Methane gas is the shortest lived, but most potent greenhouse gas. We hear from those who say reining in methane is needed to protect the climate and the health of Albertans. And we hear how a looming agreement on methane emissions in that province could make a big difference to Canada's climate goals.

A 3,700-year-old buried log still holding the carbon it had pulled from the air sparked a radical idea: bury dead trees before they release their stored CO2. Guest host Johanna Wagstaffe wades into the wonder with the scientist who made the ancient find – in Canada. Then, we hear from a company aiming to bury trees in a sort of carbon bunker, creating carbon credits to pay for reforestation. And we check in with a forest ecologist who explains why it’s not one-size-fits-all when it comes to managing forests that have burned.

Iran closed the Strait of Hormuz, a key route for oil trade, rattling global markets. Prices could remain high the longer the U.S. and Israel-led conflict with the Islamic Republic rages on. As countries scramble to shore up energy supplies, we're looking at whether it’s time to ramp up the transition to renewables — for the sake of national security and the climate. 

A coffee farmer shares the raw reality: climate change is shifting the world’s "bean belt". CBC’s Anand Ram and Inayat Singh introduce us to 5th generation farmer Chalo Fernandez who’s using social media to let people know how increasing heat is affecting his beans. We’ll break down what the science says and why these farmers are the most resilient innovators in the game. 

Is it too late to stop climate change? Not according to data scientist Hannah Ritchie. We dive into her new book, “Clearing the Air,” where Ritchie answers all the tough questions – the ones she gets all the time and the ones you’ve probably asked yourself.

From the Best of What On Earth - Canada's oil and gas companies are hoping carbon capture and storage will be a big part of the country’s net zero plans. But shipping CO2 through pipelines to storage facilities can come with risks. We go to rural Mississippi to hear about a rare carbon dioxide pipeline breach that was nearly deadly – and find out what Canada can learn from the incident

Country star Corb Lund should be rehearsing for back-to-back tours. Instead, he’s wading deeper into the debate over coal exploration and development in the Rockies. It’s been more than five years since the singer-songwriter first set aside his decades-long commitment to an apolitical public image in order to campaign against coal mining in Alberta’s eastern slopes. He has lost fans and received pushback he calls “vile” and “abusive.” But as producer Molly Segal finds out, it’s a fight the musician has no plans of giving up.

Nature gives us joy, wonder, and beauty. It also brings big bucks. Trillions of dollars, according to the Canadian Parks and Wilderness Society. It says in a new analysis that tens of thousands of jobs are among the benefits when Canada's wilderness is protected. Plus, we do the climate a solid. But there are worries that Ottawa may not keep up the stable funding needed to protect enough of Canada’s lands and water for future generations.

Clues to Earth’s climate future lie buried in the ancient ice sheet covering Greenland. Climate scientists have been working for decades to uncover answers that can help us understand what’s coming. But as the U.S. government continues to push for more control over the island, some are worried that a Greenland controlled by Donald Trump would put their access to the ice in jeopardy. Security expert Whitney Lackenbauer tells us why fears about a warming Arctic due to climate change are stoking the current geopolitical tensions, and glaciologist Martin Siegert explains why a politically stable Greenland matters for the whole planet.
