Biologically important organismal activities occur at specific times of the day, and asymmetric changes on the effects of climate change between the daytime and night-time can have a significant impact on nature. A paper published in Global Change Biology found that between 1983-2017, the area that experienced nighttime warming above 0.25°C was more than twice that of the area that experienced daytime warming in regions that showed warming asymmetry.
