Coral Reefs and Climate Change Effects

The video discusses the alarming rise in ocean temperatures leading to coral bleaching, particularly affecting the Great Barrier Reef. The XL Catlin C View survey uses advanced technology to map coral reefs, providing crucial data to assess damage post-bleaching events. Despite some reefs thriving, global trends indicate worsening conditions. Historical data shows an increase in the frequency and intensity of bleaching events, exacerbated by climate phenomena like El Nino.

What is predicted to happen to the Great Barrier Reef due to high ocean temperatures?

• A decrease in sea levels

• A major coral bleaching event

• An improvement in coral health

• An increase in fish population

What technology is used by the XL Catlin C View survey to document coral reefs?

• Sonar mapping

• Underwater drones

• 360° photographs

• Satellite imagery

What is the purpose of establishing a baseline for coral reefs?

• To improve fishing techniques

• To increase tourism

• To measure the impact of bleaching events

• To predict future weather patterns

What did the footage from other reefs around the world suggest?

• Bleaching will eventually affect all reefs

• Reefs are immune to bleaching

• Bleaching is a local phenomenon

• Reefs are thriving globally

What happens to coral reefs under stress if conditions do not improve?

• They die of starvation or disease

• They become more colorful

• They recover fully

• They thrive and grow

How quickly can coral bleaching occur under stress?

• Over several years

• In a few months

• Instantly

• Over a decade

When was the first global mass bleaching event recorded?

• In the early 1980s

• In 1998

• In 2010

• In 2015

What trend is observed in the frequency of bleaching events?

• They are becoming less frequent

• They are occurring at the same rate

• They are becoming more frequent

• They have stopped occurring

What natural phenomenon contributed to the warm conditions this year?

• La Nina

• Hurricane

• El Nino

• Monsoon

What is the impact of increasing sea temperatures on coral reefs?

• Improved coral health

• Increased fish diversity

• Decreased algae growth

• Coral bleaching
