A team of Japanese and Chinese researchers have found that yellow sand helps to slightly lower global temperature.

Masao Mikami, head researcher at the Meteorological Research Institute, said yellow sand particles reflect sunlight back to space when traveling on winds, thereby "playing a role in preventing global warming" by cooling the atmosphere.

Until now, scientists have concentrated on the negative effects of the phenomenon in which sand from China's deserts is blown eastward, affecting the Korean Peninsula and Japan. It is said to present certain health risks.
