This page on ocean warming presents interactive graphs of ocean heat content over time.
The text briefly discusses the huge amount of heat absorbed by the oceans, water expansion due to increasing temperature, and coral bleaching caused by warmer ocean temperatures.
Students may be surprised to learn that about 90% of heat from global warming is absorbed by the oceans.
Students can learn about the impacts on ocean ecosystems.
Students should know how to read a graph.
This page and NASA's other Vital Signs pages are probably best used when students are learning the basic facts about climate change.
This resource could be used in lessons about energy, ocean ecosystems, sea level rise, the physical properties of water, extreme weather, hurricanes, or the importance of our oceans to maintain life on Earth.
Any class could use this resource for fact-checking, research, or data analysis related to climate change and sea level rise.
