A rogue wave is defined as being at least 2.2 times as high as the average waves which have come before. They are described as coming out of nowhere and their consequences can be deadly.

In her documentary, The Wave, Joan Webber chronicles swimmers struck by these potentially deadly maritime phenomena. Though rogue waves themselves are not infrequent, it's considered rare that a person is hit by one. But rare .… is not never.

We also bring you another story about the sea titled, When I Came to Canada. It’s Hon Lou’s harrowing account of fleeing Vietnam by boat as a child following the end of the Vietnam war.

The Wave was produced by Joan Webber with help from Liz Hoath and originally aired on The Current.

When I Came to Canada first aired on Living Out Loud and was produced by Steve Wadhams.

In Vancouver's Lower Mainland, a dealer known only as "Jay" sold drugs to teens, making drop-offs right next to their high schools and homes, offering free "goodie bags" of Xanax and other drugs.

When Julie Nystrom discovered her 17-year-old daughter was hooked on counterfeit pills from Jay, she went to the police. The cops told her that they needed names, details, so she decided to take matters into her own hands and hired a private investigator.

On this episode of Storylines, the documentary Everybody Loves Jay, which tells the story about the lengths one mother went to protect her daughter from a drug dealer.

Produced by Enza Uda and Joan Webber / originally aired on The Current.

In an empty parking lot somewhere in northern California, Andrew Song and Luke Iseman inflate a balloon the size of a small car, full of sulfur dioxide. They will then launch the balloon high up into the stratosphere where it will pop, releasing its sulfur dioxide contents.

Song and Iseman are the co-founders of Make Sunsets, a geoengineering startup that sells cooling credits. For a price, you can purchase a bit of the sulfur dioxide they’re pumping into these balloons and launching into the stratosphere, with the belief it will offset the warming effects of CO2.

Because if you send enough sulfur dioxide into the stratosphere --- we’re talking a million tonnes a year --- it’ll significantly cool our warming planet. But the idea raises scores of complicated scientific and moral dilemmas.

In this documentary, John Chipman goes to California to learn about the potential risks and benefits of solar geoengineering.

Reported and produced by John Chipman, with assistance from Joan Webber and Catherine Rolfsen. Mixed by Michelle Parise . It originally aired on What on Earth.
