Introduction: Dangerous Rise of Oceans (02:10)

FREE PREVIEW

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.

Phytoplankton (02:02)

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.
