Scientists debunk claim that trees can anticipate a solar eclipse, as suggested by 2025 study
The claim that one type of tree—Picea abies—can anticipate a solar eclipse through electrical signals is based ‘on speculative interpretations and unsupported evolutionary assumptions,’ according to an opinion piece published in the journal Trends in Plant Science. The paper refutes another from 2025 that claimed these trees synchronised their bioelectrical behaviour hours before a solar eclipse in Italy's Dolomite region. According to the authors of the new article, this electrical activity can be explained by temperature changes and atmospheric electrical discharges.
