How dandelion seeds take flight, and more…

In a study inspired by a field of dandelions, researchers wanted to know why, when you blow on a dandelion seed head, only the seeds closest to you take flight. They found that a dimple in the seed heads where the seed attaches is larger on one side than the other, and that the seeds consistently broke off from the smaller side of that dimple. Once they take flight, each dandelion seed uses its unique shape to catch a ride on the wind.

Three decades later, the Accords are primarily remembered as a failure. Nahlah Ayed and guests discuss what went wrong, and what lessons the Oslo Accords hold for the future.

Will smoky skies spur sharper climate action in Ottawa?

As Ottawa choked on wildfire smoke, climate was left off the agenda in the House of Commons. CBC’s Aaron Wherry explains why it might seem like Canada's climate debate is stuck in the past. We meet 17-year-old Aishwarya Puttur who is fighting for the planet and debuts as our new youth columnist. Producer Molly Segal finds out how to pack a “go bag” in case wildfires force you from your home. An international project out of the University of Victoria aims to share the stories of climate disaster survivors in ways that help them heal. And a boost from the federal government for fossil fuel workers looking to go green.

Sneaking climate action into your summer block party

How can you talk to your neighbours about climate change and work on solutions together? We hear about a UBC program training people across the country to do just that. And we meet a few of them as they plot to plant “plainclothes environmentalists” at their next community gathering. Then we go back in time to the oil shocks of the 1970s and 1980s for clean energy lessons that have new relevance today. And we meet a community of people making home retrofits a neighbourhood effort.
