How Climate Change Has Intensified Hurricane Season

Synopsis
This video from NowThis Earth provides evidence of hurricanes like Ida and Harvey causing more precipitation and becoming stronger, slower, and larger than in the past.
The video includes footage of Katharine Hayhoe discussing these events and providing examples of hurricanes that have hit Louisiana, Houston, and the rest of Gulf Coast.
Students may be surprised to learn that 93% of the extra heat trapped by greenhouse gases is absorbed by the oceans, which may help them make the connection between higher ocean temperatures and stronger hurricanes.
The information is presented in a very logical and easy-to-follow manner.
Prerequisites
Students should have a basic understanding of the greenhouse effect.
Students should understand that heat is a form of energy.
Differentiation & Implementation
Social studies and economics classes can discuss the human and environmental costs of more powerful and/or longer-lived storms and compare those with the costs of addressing climate change, taking into account the additional loss of life (which cannot be measured financially) that may occur from more extreme storms.
Biology and/or chemistry classes can use this resource as a hook for lessons about the flow of energy through ecosystems, the increasing capacity of the atmosphere to hold more water vapor at higher temperatures, and the effects of heat on chemical reactions, the density of liquid water, and the reduction in dissolved oxygen available in the oceans.
