Introduction: Dangerous Rise of Oceans (02:10)
This brief overview of rising ocean levels orients viewers with excerpts from the upcoming program.
Great Southern Ocean (02:45)
The Southern Ocean holds forty percent of ocean carbon dioxide. The Circumpolar Current is the largest ocean current; plunging currents absorb CO2 below the surface. Scientists gather data to monitor the Southern Ocean.
Argo Data (02:29)
Data shows that the Southern Ocean absorbs more heat than the rest of the globe. Lower salinity levels, due to ice sheet melt, is cause for concern.
Plankton is important to ocean life and global carbon dioxide levels. Ocean warming reduces plankton in the ocean.
Great Barrier Reef (03:33)
Bernice Notenboom travels to the Heron Island Research Station to explore coral reefs with Prof. Ove Hoegh-Guldberg. Heron Island Research Station scientists study the role of coral reefs in the ocean system.
Coral Triangle (03:56)
Coral responds negatively to rising sea temperatures. Learn how coral colonies grow. Explore the Great Barrier Reef with Notenboom.
Coral Tipping Point (03:12)
Increased ocean temperatures and carbon dioxide levels are harmful to coral. A team of scientists is developing an early warning system to monitor the oceans.
Coral Predictions (05:15)
Professor Ove Hoegh-Guldberg's developed replicas of oceans past and future. He discusses the worst case scenario of global warming.
Symbiotic Relationships (03:14)
The reefs are losing plants and animals that serve functional roles. Reefs are in cooperative relationships with tiny algae.
Australia's Vulnerability (03:40)
Australia is particularly susceptible to climate change. Weather patterns in the changing climate are not favorable.
Tuvalu Under Threat (04:53)
As the ocean temperature rises, storms and sea level increase. This island nation could cease to exist if ocean levels continue to raise.
Tuvalu Residents (02:53)
Notenboom talks with residents about climate change and how it affects their lives. They consider the possibility of being forced to leave the island.
Tuvalu Food (04:15)
Notenboom attempts spear fishing with local fishermen; a storm moves in. Climate change hinders the island inhabitant's ability to farm. Much of the island now relies on imported food.
Tuvalu King Tide (02:39)
The local meteorologist noticed an increase in storm intensity in the last ten years. Tuvalu residents prepare to weather the coming storm and king tide.
Point of No Return (02:35)
Review critical climate change discussed in this film and how it affects the oceans. Explore potential actions that may help combat these changes.
