High temperatures in the cold months disrupt the natural cycle of species such as almond trees and can endanger their survival. High temperatures vary the rhythms of many plants, which in mild autumns and winters bloom earlier and can even do so twice.

The temperatures of September and October last year, much warmer than usual, turned autumn into a second spring, indicates the public Center for Ecological Research and Forestry Applications (CREAF) Andrés Bravo, researcher at the National Museum of Natural Sciences, raises the need to investigate the effects of high winter temperatures.
