Positives

• This is a valuable tool to understand how quickly global average temperatures have changed in recent decades.
• Students can access the exact data used to create the spiral.

Additional Prerequisites

• Students should understand how global warming is measured (degree increase above pre-industrial levels).
• The video can be slowed down to make it easier to track the changes in the spiral over time.

Differentiation

• Have students consider what it means for humanity and the planet when the increase in temperature above pre-industrial levels surpasses 1, 1.5, and 2 degrees Celsius.
• Ask students why they think temperatures started to increase more dramatically after the mid-20th century.
• Students can use the data provided to create their own data visualizations.
• This resource can also be used in math or statistics classes during lessons about data visualization.
