a. Melting of ice sheets and glaciers, combined with the thermal expansion of seawater as the oceans warm, is causing sea level to rise. Seawater is beginning to move onto low-lying land, contaminating coastal fresh water sources, and gradually submerging coastal facilities and barrier islands. Sea-level rise increases the risk of damage to homes and buildings from storm surges such as those that accompany hurricanes.

This is a short experiment to demonstrate the concept of thermal expansion of water when heated, as an analogy to thermal expansion of oceans due to global warming.

This series of visualizations show the annual Arctic sea ice minimum from 1979 to 2015. The decrease in Arctic sea ice over time is shown in an animation and a graph plotted simultaneously, but can be parsed so that the change in sea ice area can be shown without the graph.

This module contains five activities, in increasing complexity, that focus on understanding how to interpret and manipulate sea level data, using real data from NOAA.

This web mapping tool allows users to investigate impacts of sea level rise. Data is included from across the United States at different scales. Various timelines and sea level rise projections can be explored.

This activity allows students to demonstrate the thermal expansion of water for themselves using water bottles and straws. The discussion allows them to explore the connection between this concept and sea level rise due to climate change.

This activity allows students to explore sea level rise. The experiment allows them to test whether land ice and/or sea ice contribute to sea level rise as they melt.

This video discusses impacts that the Midwestern US is experiencing due to climate change. It describes how climate change is affecting agriculture, tourism, drought and flood, water cycles and freshwater availability, the spread of invasive species and disease, as well as other topics.

This very short video introduces the concept of sea level rise and ties it back to global warming. The video is brief, basic, and clear. It can be used for a quick introduction, but nothing deeper than that.
