Ocean and Cryosphere Climate Impact

The video discusses the critical role of the ocean and cryosphere in sustaining life and regulating the global climate. It highlights the impacts of climate change, such as permafrost thawing, glacier melting, and sea level rise, which threaten ecosystems, water resources, and human infrastructure. The video emphasizes the need for adaptation and mitigation strategies, including reducing emissions and engaging local communities, to protect these vital systems and secure our future.

What role do the ocean and cryosphere play in the global climate system?

• They provide food and water and are key components of the climate system.

• They are only important for marine life.

• They only affect the polar regions.

• They are insignificant to the climate system.

What is a significant consequence of permafrost thawing in the Arctic?

• Formation of new ice sheets

• Increase in polar bear population

• Decrease in global temperatures

• Release of vast amounts of carbon

How does glacier melting in high mountain regions affect water availability?

• It increases water availability permanently.

• It only affects water availability in polar regions.

• It initially increases, then decreases water availability.

• It has no effect on water availability.

What is a major impact of sea level rise on small islands?

• Erosion and loss of land

• Decrease in saltwater contamination

• Increase in land area

• Formation of new freshwater sources

What percentage of excess heat in the climate system has the ocean absorbed over the past few decades?

• Exactly 75%

• About 10%

• More than 90%

• Less than 50%

What is one of the effects of ocean acidification?

• Decrease in CO2 levels

• Increase in oxygen supply to marine life

• Decrease in the ability of organisms to build shells

• Increase in marine biodiversity

What is a key strategy to protect the ocean and cryosphere?

• Increasing greenhouse gas emissions

• Focusing only on technological solutions

• Ignoring local communities

• Engaging with local communities and reducing emissions

What is the goal for emissions to protect the ocean and cryosphere?

• Increase emissions by mid-century

• Reach Net Zero emissions by mid-century

• Maintain current emission levels

• Double emissions by mid-century

Why is it important to consider the faces of vulnerable people when addressing climate change?

• To focus only on economic benefits

• To prioritize their needs and create effective solutions

• To delay action until they are affected

• To ensure they are ignored

What is the main cause of the changes in the ocean and cryosphere?

• Natural climate cycles

• Human-induced greenhouse gas emissions

• Decreased solar activity

• Increased volcanic activity
