Explain the NADW in the context of global climate change
What will be an ideal response?
The North Atlantic Deep Water Circulation Pattern is a sort of conveyor belt that moves less salty (fresher), less dense warmer water from the equatorial zones northward, carrying heat to higher latitudes in the Atlantic Ocean, thus moderating Europe's climate. Recently, scientists have realized that interrupting the NADW could trigger climate change. If global warming causes large portions of the Greenland ice sheet to melt, freshwater runoff into the North Atlantic would increase. Surface waters would become less dense from the dilution and warming because warm freshwater is less dense than cold saltwater. This could stop the northward flow of warm equatorial water, whereby the entire North Atlantic region, including much of Europe, could cool rapidly as a result.

Which of the following statements most accurately describes the relative "risk" of getting a sliver in your finger versus a volcanic eruption in the Pacific Northwest?
A) The relative "risk" is difficult to assess because, even though getting the sliver is much more likely, the volcanic eruption would be much more severe. B) A volcanic eruption in the Pacific Northwest is much more likely and so has the higher risk. C) The relative risk is roughly equal because both events are roughly equally likely, and both would be roughly equally severe. D) Getting a sliver in your finger is much more likely and so has the higher risk.
