CNN's Chief Climate Correspondent Bill Weir marks Earth Day with this captivating adventure, crossing the globe to interact with the most innovative players in the trillion-dollar race to remove carbon from the sea and sky. Since human activity has released a monster made of more than one trillion tons of carbon into the Earth's atmosphere, innovators and investors are joining the global race against time to defeat it. With tools that include everything from Icelandic geysers to humpback whales, they are putting down stakes in the most significant new industry you've never heard of.

From Silicon Valley to Cambridge and aboard hot air balloons in the Swiss Alps and fishing boats in Maine, Weir searches for perspective, hope, and ideas. "If science and stone-cold evidence are telling us that the future is screwed, how do we unscrew a planet?" Weir said, explaining the show's inspiration. "I went looking for the biggest, boldest ideas in planetary repair and came back blown away, both by the scale of the challenge and the wave of new ideas being put into action every day."

Weir analyzes innovative carbon removal techniques that mimic nature itself, including spraying the ocean with artificial whale feces made of volcanic ash, creating synthetic clouds made of seawater mist, and sinking carbon-absorbing seaweed buoys to the bottom of the ocean. He speaks with leading experts in their field, including Swiss explorer and environmentalist Bertrand Piccard who was the first person to complete a non-stop balloon flight around the globe, former Chief Scientific Advisor to the UK Government and founder of the Center for Climate Repair at Cambridge University Sir David King, and Silicon Valley titan Peter Reinhardt, who co-founded and is CEO of carbon removal tech company Charm Industrial®.

CNN Chief Investigative Correspondent and Anchor Pamela Brown investigates claims made by some of the thousands of women and men who say that Johnson & Johnson's now-discontinued talc baby powder is responsible for their cancers. 

Johnson & Johnson is an American institution. The corporate behemoth, worth more than 400 billion dollars, is the company behind Tylenol, Band-Aid, and Neutrogena, which can all be found in homes nationwide. Marketed both for use by children and adults, Johnson & Johnson's baby powder became one of the company's most iconic products. When allegations arose that the talc baby powder contained traces of cancerous asbestos, Johnson & Johnson vehemently denied those claims. They have consistently cited the safety of their product and said that it does not contain asbestos or cause cancer. Despite this, based on those allegations, there are nearly 40,000 lawsuits against Johnson & Johnson.

In this investigation, Brown hears the powerful stories of several women suing Johnson & Johnson following their cancer diagnoses and speaks with attorneys on both sides of the case – plaintiffs' attorney Jerome Block and attorney for Johnson & Johnson Allison Brown. She also interviews Senator Dick Durbin, Chair of the Senate Judiciary, on Johnson & Johnson's attempt to create a subsidiary for its talc liabilities and limit its exposure to litigation through bankruptcy court.
