Average Review Ratings (Poor to Excellent, 1-5 scale):

Description:This site is a great source for climate data, but it is not designed with educators as the audience. Educators using this site need some background knowledge and experience with accessing and using online data. I use sites like these to find authentic scientific data that my students can graph and analyze. (JG)

Summary of Reviews 

Reviewer: Carrie Morrill
Comments:Site contains raw data and graphs of (1) atmospheric concentrations of greenhouse gases through time and (2) emissions of greenhouse gases by countries and states. Would be nice to see more activities to go along with these data, although sometimes the data are difficult to interpret (too many confounding factors). Data selections on temperature, clouds and ecosystems extremely limited, to the point of giving an inaccurate representation of data available on these subjects.

Reviewer: Jack Ganse
Comments:Educators who are intent on exploring global climate and climate change seriously should consider using this site and the data it contains. This site illustrates the process of research science well. Any educator who wishes to understand climate and climate change at the scientific level should spend time exploring this site. Novice educators can certainly harvest a wealth of graphics from this site while more experienced educators can access and use the digital data with their students. The research background material is excellent for learning more about the science.
