Sea Level Rise and Climate Change

The video discusses the impact of human activities on climate change, focusing on the increase in carbon dioxide levels and the resulting global warming. It explains the effects of climate change, such as rising sea levels and increased flooding risks, particularly in coastal areas. The video explores the causes of sea level rise, including thermal expansion and glacier melting, and provides future projections based on different emission scenarios. It also examines factors influencing sea level, such as tides and weather, and the impact of storm surges on coastal flooding. Finally, it discusses modeling techniques for predicting coastal flooding.

What has been the primary cause of the increase in carbon dioxide levels since the Industrial Revolution?

• Deforestation and burning of fossil fuels

• Increased solar activity

• Natural volcanic activity

What is a storm tide?

• A tide that occurs during a full moon

• A tide that coincides with a storm surge

• A tide that occurs during a new moon

What is the significance of mean sea level in measuring coastal elevations?

• It is the average height of the water over a 5-year period

• It is the average height of the water over a 19-year period

• It is the highest point of the tide

• It is the lowest point of the tide
