A new study has shown that the nocturnal environment is warming at a faster rate than the daytime environment and could be detrimental to many species. Researchers at the University of Exeter analyzed more than three decades of daily temperature data from around the world before concluding that there is an asymmetry in the warming of the planet as it rotates on its axis. According to a statement from the University of ExeterGlobal warming is affecting daytime and nighttime temperatures differently. In addition, greater warming at night is more common than greater warming during the day worldwide. The researchers studied atmospheric warming from 1983 to 2017 and found a difference in mean annual temperature of more than 0.25 degrees between day and night warming over more than half of the world’s land area. They found that days warmed up faster in some places and nights in others. However, the disproportionately larger total area of ​​nocturnal warming was more than double. According to the scientists, the “warming asymmetry” is mainly due to changes in cloud cover levels. The night is warming at a faster rate than during the day and could be harmful to many species: studyRepresentative image According to the study authors, increased cloud cover cools the surface during the day and retains heat at night. This leads to more nightly heating. On the other hand, the decrease in cloud cover allows more heat to reach the surface during the day. However, that warmth is lost at night. Speaking of which, lead author Dr Daniel Cox of the Institute for Environment and Sustainability at Exeter’s Penryn campus in Cornwall said that warming asymmetry has significant implications. for the natural world. “We show that increased nighttime warming is associated with increasingly humid weather, and this has been shown to have important consequences for plant growth and the way species, such as insects and mammals, interact, “Cox said, adding that greater daytime warming is associated with drier conditions and greater overall warming, increasing the vulnerability of species to heat stress and dehydration. The article has been published in Global Change Biology magazine.
