Climate Change and Ocean Dynamics

Paul Beckwith discusses the impact of climate change on Hurricane Matthew, highlighting how increased sea surface temperatures and water vapor contribute to more powerful storms. He tracks Matthew's path, noting record-setting aspects and the role of ocean currents. The video also covers sea level rise, wave height, and the Gulf Stream's influence, emphasizing the changing climate's effect on storm frequency and intensity.

What is one of the main factors that has contributed to the increased intensity of Hurricane Matthew?

• Decreased atmospheric pressure

• Increased sea surface temperatures

• Lower humidity levels

• Higher wind speeds

What is the effect of increased water vapor in the atmosphere on storms?

• It reduces storm duration

• It fuels more intense storms

• It has no effect on storms

• It weakens storms

Which force causes moving objects in the Northern Hemisphere to deflect to the right?

• Gravitational force

• Magnetic force

• Electromagnetic force

• Coriolis force

What is a sea surface temperature anomaly?

• A sudden drop in ocean temperature

• A deviation from the 30-year mean temperature

• A change in ocean salinity

• An increase in atmospheric pressure

What is the critical sea surface temperature needed for hurricanes to extract energy?

• 30 degrees Celsius

• 20 degrees Celsius

• 24 degrees Celsius

• 26.2 degrees Celsius

How does the Gulf Stream affect sea level along the US East Coast?

• It increases sea level

• It has no effect on sea level

• It causes sea level to fluctuate randomly

• It decreases sea level

What is one consequence of the slowing Gulf Stream on the East Coast?

• Lower sea surface temperatures

• Increased water pile-up on the coast

• Reduced wave heights

• Decreased storm frequency

What percentage of global warming's heat is absorbed by the oceans?

• 50%

• 90%

• 70%

• 100%

What unusual path did Hurricane Sandy take when it hit New York?

• A straight path

• A left turn

• A circular path

• A right turn

What is one of the changes in jet stream behavior due to climate change?

• Decreased altitude

• More stable patterns

• Faster speeds

• Slower and wavier patterns
