National Oceanic and Atmospheric Administration, (NOAA)

This is an interactive website that provides descriptive information and data related to ten key climate indicators. These climate indicators and related resources show global patterns and data that are intuitive and compelling teaching tools.

Climate Literacy
About Teaching Climate Literacy

Covering 70% of Earth's surface, the ocean exerts a major control on climate by dominating Earth's energy and water cycles. It has the capacity to absorb large amounts of solar energy. Heat and water vapor are redistributed globally through density-driven ocean currents and atmospheric circulation. Changes in ocean circulation caused by tectonic movements or large influxes of fresh water from melting polar ice can lead to significant and even abrupt changes in climate, both locally and on global scales.

mate is regulated by complex interactions among components of the Earth system

Climate is determined by the long-term pattern of temperature and precipitation averages and extremes at a location. Climate descriptions can refer to areas that are local, regional, or global in extent. Climate can be described for different time intervals, such as decades, years, seasons, months, or specific dates of the year.
About Teaching Principle 4
Other materials addressing 4a
Climate is not the same thing as weather. Weather is the minute-by-minute variable condition of the atmosphere on a local scale. Climate is a conceptual description of an area’s average weather conditions and the extent to which those conditions vary over long time intervals.
About Teaching Principle 4
Other materials addressing 4b
Climate change is a significant and persistent change in an area’s average climate conditions or their extremes. Seasonal variations and multi-year cycles (for example, the El Niño Southern Oscillation) that produce warm, cool, wet, or dry periods across different regions are a natural part of climate variability. They do not represent climate change.
About Teaching Principle 4
Other materials addressing 4c
Scientific observations indicate that global climate has changed in the past, is changing now, and will change in the future. The magnitude and direction of this change is not the same at all locations on Earth.
About Teaching Principle 4
Other materials addressing 4d
Environmental observations are the foundation for understanding the climate system. From the bottom of the ocean to the surface of the Sun, instruments on weather stations, buoys, satellites, and other platforms collect climate data. To learn about past climates, scientists use natural records, such as tree rings, ice cores, and sedimentary layers. Historical observations, such as native knowledge and personal journals, also document past climate change.
About Teaching Principle 5
Other materials addressing 5b
understanding of the climate system is improved through observations, theoretical studies, and modeling
About Teaching Principle O

man activities are impacting the climate system
About Teaching Principle H
Other materials addressing Hum
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.

Teaching Tips

  • In order to use this interactive as part of a rich lesson or unit, educator should examine all of the links to resources.
  • An entire week's worth of information to support the ten signs of warming are supplied on the website. Educators can personalize the extent to which they want to use this information for various age levels and range of content coverage.

About the Science

  • Within each of the 10 indicators, individual datasets can be explored for further inspection and zoomed in to specific periods of interest.
  • All data used are publicly accessible.
  • The 2009 State of the Climate served as a basis for the content on this website.
  • Comments from expert scientist: NOAA is an excellent organization devoted to atmospheric and oceanic research. Consequently, there are a large number of experts in climate change related to the topics presented in:"10 Signs of a Warming World". The final result is also excellent.

About the Pedagogy

  • Links to the reports that provide the content background are included. More importantly, there are many links under each indicator that lead to graphs of data trends, videos, feature articles, and grade-level resources in the CLEAN resource collection.
  • The interactive map provides a learn-more option that brings the user to an entire web page featuring data trends, articles, and multimedia that support that indicator of warming.

Technical Details/Ease of Use

  • The interface is very clear and easy to use.
  • Must have internet or can use the teacher-provided Powerpoint presentation (lower left-hand corner of site) if internet connection is not available.
