Rather than running exhaustive searches on Lexis, Westlaw, Bloomberg Law or Hein Online, it can be helpful to narrow your results on a topic by using an abstract service like Westlaw's Legal Resource Index. The difference with an abstract service is that human beings have summarized articles in select journals. Searching those summaries is more likely to find a solid article on point.
In the image below, the Legal Resource Index is located to the right on the Westlaw's Secondary Sources page.
Select terms for your search that are sufficiently narrow. In this case, I want articles at the intersection of the "Endangered Species Act" and "climate change."
The thirty-three results are ranked by relevancy (with the best documents on top).
Searching all of the law reviews and journals on the other hand produces 2,732 results (far too many for effective review).
Washington and Lee University has a tool for ranking law journals by speciality at http://lawlib.wlu.edu/LJ/index.aspx. You usually can't access articles directly, but you can get an idea of where to start.
Using the tool below you can view SSRN's eJournal depositories for Environmental Law. Note that for the first choice, Environmental & Natural Resources Law eJournals (which includes all of the different journals), you can change the order in which articles are presented from the most recent, to the oldest, by the most cited, by the name, etc.
