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.

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

  • Educators could seed a discussion of this map with questions about why certain impacts are projected for different regions.
  • Important caveat at the bottom of the page notes that adaptive capacity not taken into consideration.
  • Given that 2 degrees C is now a likely minimum of change, what can be done to adapt human systems to the change and how will ecosystems on which we depend adapt?

About the Science

  • This visualization shows some of the major global impacts from a global mean temperature rise of 2 degrees Celsius.
  • It was produced by the UK Met Office - Hadley Centre.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • The map is information-rich.
  • It encourages students to explore how a number of different impacts are connected to temperature rise and to each other, and how these impacts differ around the globe.
