Aren't there already a plethora of peer-reviewed journal articles on the issue of climate change? Why is it still necessary to store the presumably raw data?
Even my high school geography notes have an abundance of information on the issue of climate change (for and against). So I doubt if this is necessary at all.
What is in your high school geography notes was dictated in part by political decisions about school curriculum - you cannot assume that the future of even high school geography notes will match your experience.
Just like you have new versions of a program building on changes to source code, you can run newer and improved analysis on the scientific data (whether to see if you get the same result, a new additional insight or whatever).
Journal papers are often no better than having the binary (or perhaps more accurately the stdout dump of running the binary...)
