"""Has anyone tied the magnetic field or solar storms to ecosystem tipping? A search of OpenAlex.

Fact-Checked Science, November 2026, for the paper check /biosphere-tipping-warning/ ("Our analysis").
Standard library only. No e-mail address or other personal data is sent.

Rule, stated before the run: ten pairings of a magnetic or solar term with a tipping or resilience term, as phrases in
titles and abstracts, read in full; then a wider pass, listing only the five most-cited results of each, unread.
An empty result says we found none. It doesn't prove there is none: the index misses papers and wordings.

Run it: python3 openalex_search.py
