Climate change has raised average nighttime temperatures much faster than daytime ones, according to a recent study. The world’s first comprehensive research on the subject was published on Wednesday.

The researchers compared the change in night and day temperatures between 1982 and 2017 and found that in most parts of the world, night temperatures had risen by at least 0.25 degrees Celsius more than day temperatures.

The phenomenon was observed in Europe, West Africa, western South America, and Central Asia, among others. On the other hand, in the southern United States and Mexico, among others, and in the Middle East, days warmed up faster than nights.

According to researchers, the cause of the phenomenon is the changes in the clouds caused by climate change. In certain areas, increased cloud cover prevents sunlight from entering the ground during the day, but, like the cover, retains heat and moisture in the ground at night. Especially in already dry areas, the changes in the clouds are less.

Uneven warming between times of day interferes with the circadian rhythms of animals and plants. This will lead to new problems for fauna and flora, which are already having difficulty adapting to global warming.

In the past, global warming has also been found to be unevenly distributed geographically.
