Sea-level accelerating faster than previously thought: study

The video discusses the historical and recent trends in sea level rise, highlighting a minimal increase from 1900 to 1990, followed by a more significant rise of 1.2 inches per decade. This increase is attributed to global warming, specifically the thermal expansion of seawater and the melting of glaciers and ice sheets. Additionally, human activities such as irrigation projects contribute to the faster flow of water from land to ocean.

What was the rate of sea level rise between 1900 and 1990?

• 1 inch per decade

• Less than half an inch per decade

• 1.2 inches per decade

• 2 inches per decade

What is the current rate of sea level rise per decade?

• 0.5 inches

• 2 inches

• 1 inch

• 1.2 inches

Which factor is NOT linked to the recent increase in sea level rise?

• Thermal expansion of seawater

• Melting of glaciers

• Volcanic eruptions

• Human irrigation projects

What is one of the main causes of sea level rise due to global warming?

• Thermal expansion of warmer seawater

• Increased ocean currents

• Increased rainfall

• Decreased ocean salinity

How do human activities contribute to sea level rise?

• Through deforestation

• By increasing ocean salinity

• Through irrigation projects

• By reducing ocean currents
