The Fate of the Oceans

On CBC Newsworld, Sundays at 6:30 PM ET.
This week, we have a special broadcast from Vancouver. We look at rising fears about how we're damaging our Oceans and the impact we're already seeing on weather systems and nature around our globe. Brian interviews a top marine scientist, Thomas Okey. And Darrow MacIntyre brings us a feature report on how scientists are trying to better predict erratic weather patterns by studying changes deep within the oceans.
In discussions about climate change, we often overlook oceans, because they seem so vast and immutable. But experts say deterioration has accelerated over the past generation. Right now, there is more pressure on the oeans than we've ever seen before. It's caused by over-fishing, pollution, and climate change. Entire coastal regions are being transformed. The oceans are warming and in turn changing weather patterns in dangerous ways. Worse, scientists just don't know the combined effects of this decline for the planet as a whole. They do speak of a crisis. And they explain that we need to understand these changes so we can begin to take action. They also warn that we have a narrow window of opportunity to respond to these challenges, because time is limited
In Vancouver, Brian meets a leading expert on the oeans, a scientist who says he has seen dramatic and alarming change over the course of his own career. Thomas Okey is a marine ecologist who studies the effects of climate change on ocean life. He is sceintist in residence at the Pew Institute for Ocean Science.
The changes to the oceans impacts us in many different ways, notably in producing erratic weather patterns, some of it extreme and dangerous. Scientists are looking more and more to the oceans for clues to weather patterns. CBC reporter Darrow MacIntyre talks to some scientists involved in a fascinating deep sea project. Sending robots deep into the ocean--up to 1,000 feet, to measure temperature and salt content. This helps them predict and monitor weather in an exciting new way.
