An interesting recent study by librarians Kari Kozak and Laura Sare looks at publications on climate change distributed by the Government Printing Office (GPO) Federal Depository Library Program over the past 40 years. Climate change coverage is analyzed by year, presidential administration, issuing agency, nature of the publication, topic, audience, and attitude toward climate change. The study also compared government documents with scientific journals accessed via Web of Science. The conclusions are in some cases expected but in others quite surprising.

I love a good application of bibliometrics.
