Fires in South Africa, which are so big that they can be seen from space satellites, are having an outsized effect on the world’s climate, according to a new study published by the Proceedings of the National Academy of Science on Monday.

Researchers from the University of Wyoming found that the smoke generated by these fires drifts over the southeast Atlantic Ocean, enhancing the brightness of low-level clouds in the region. This reflects light coming from the sun, creating a cooling effect that counteracts the warming produced by greenhouse gases.

Xiaohong Liu, from the Department of Atmospheric Science at the University of Wyoming and Zheng Lu, an associate in Liu's group, made their findings by modeling the smoke and its effects on the clouds using a supercomputer.

They found that layers of smoke and clouds in the atmosphere are closer to each other than previously thought and that this accelerates the Remote Automation clouds’ cooling effect. The reason for this is that the smoke contains tiny aerosol particles o grid LTE router n which water vapor condenses, increasing the clouds’ brightness.
