Climate Literacy
About Teaching Climate Literacy

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 and to contaminate coastal fresh water sources and beginning to submerge 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.
About Teaching Principle 7
Other materials addressing 7a
Climate plays an important role in the global distribution of freshwater resources. Changing precipitation patterns and temperature conditions will alter the distribution and availability of freshwater resources, reducing reliable access to water for many people and their crops. Winter snowpack and mountain glaciers that provide water for human use are declining as a result of global warming.
About Teaching Principle 7
Other materials addressing 7b
Incidents of extreme weather are projected to increase as a result of climate change. Many locations will see a substantial increase in the number of heat waves they experience per year and a likely decrease in episodes of severe cold. Precipitation events are expected to become less frequent but more intense in many areas, and droughts will be more frequent and severe in areas where average precipitation is projected to decrease.

Other materials addressing 7c
The chemistry of ocean water is changed by absorption of carbon dioxide from the atmosphere. Increasing carbon dioxide levels in the atmosphere is causing ocean water to become more acidic, threatening the survival of shell-building marine species and the entire food web of which they are a part.

Other materials addressing 7d
Ecosystems on land and in the ocean have been and will continue to be disturbed by climate change. Animals, plants, bacteria, and viruses will migrate to new areas with favorable climate conditions. Infectious diseases and certain species will be able to invade areas that they did not previously inhabit.

Teaching Tips

  • This chart can be used in a presentation or easily embedded in a unit on ecosystems, carbon cycle, or global change.

About the Science

  • The chart illustrates predicted impacts (Food, Water, Ecosystems, Extreme Weather Events, and Risk of Abrupt and Irreversible Changes) of climate change for specific global temperature increases.

About the Pedagogy

  • There are multiple links to other sources.
  • The chart is easy to read but requires interpretation.

Technical Details/Ease of Use

  • The dashed line, to solid line, to darker line implies an increase in the magnitude of the impact, but this is not stated explicitly.
