Climate Change and Sea Level Rise

The video discusses climate change, highlighting evidence of global warming, human impact through greenhouse gas emissions, and future climate projections. It explores the link between extreme weather events and climate change, emphasizing the role of water vapor. The video also covers sea level rise, its causes, and uncertainties in future projections.

What is the primary cause of the warming trend observed over the 20th and early 21st centuries?

• Natural climate cycles

• Human activities, especially greenhouse gas emissions

• Solar radiation changes

• Volcanic eruptions

What is the projected temperature increase by the end of the century if emissions are not reduced?

• No significant increase

• 1 to 2 degrees Celsius

• 3 to 5 degrees Celsius

• 6 to 8 degrees Celsius

How do different types of extreme weather events respond to climate change?

• All respond in the same way

• They respond differently based on their connection to climate change

• They are not affected by climate change

• They only occur in specific regions

What is the main factor controlling the amount of water vapor in the air?

• Wind speed

• Cloud cover

• Air pressure

• Temperature

What is the primary reason for the current sea level rise?

• Tectonic activity

• Increased rainfall

• Thermal expansion of ocean water

• Melting of sea ice

Why does melting sea ice not contribute to sea level rise?

• It does contribute significantly

• Sea ice is already floating

• It evaporates before reaching the ocean

• It is absorbed by the land

What is a significant source of uncertainty in predicting future sea level rise?

• The frequency of hurricanes

• The rate of ice loss from Greenland and Antarctica

• The amount of rainfall

• The number of volcanic eruptions

What is the expected rate of sea level rise in the coming century?

• It will decrease

• It is uncertain, could be between 1 to 6 feet

• It will remain constant

• It is certain to be 1 foot

What is the role of glaciers in sea level rise?

• They only affect local sea levels

• They prevent sea level rise

• Their melting contributes to sea level rise

• They have no impact

What is a key challenge in predicting the impacts of climate change?

• Unpredictable human behavior

• Inconsistent weather patterns

• Uncertainty in ice melt rates

• Lack of data
