The 'ghost of the desert' is eating through the ozone layer, making the earth 'difficult to breathe'?
Desert dust - fine and capable of reaching high into the sky like ghosts - has the ability to destroy many pollutants, but also silently causes terrifying effects.
The study, just published in Science Advances, helps scientists more comprehensively assess the relationship between the soil cycle and the atmosphere, thereby having more accurate strategies in efforts to clean up the earth's air, fight against climate change again.
Atacama Desert, where Iodine in the desert dust inexplicably gasses, like a "ghost" rising up and destroying the ozone layer
A team of scientists from the University of Colorado at Boulder (USA) found that iodine (Iodine), a chemical common in soil and easily airborne in desert dust, has the ability to clean many forms of gas. pollution, including Ozone, which if on the ground is extremely toxic to humans.
But on the contrary, it makes many other greenhouse gases last longer, which means that while we remove harmful things when we breathe in, they contribute to global warming.
The finding also provides another warning: if it rises high enough, not from desert dust, but once modified and hidden in gas molecules, it could be through some sort of industrial action. By human activity, it will corrode the ozone layer, which is an important layer of protection for the Earth from harmful radiation, according to SciTech Daily.
"Therefore, it is necessary to avoid adding iodine to the stratosphere," warns Professor Rainer Volkamer, lead author of the study.
Previously, through data obtained from survey flights off the coast of Chile and Costa Rica, scientists found that the dust blowing in this area is surprisingly rich in iodine. Other observations from a source of desert dust from the Atacama and Schura in Chile and Peru show that the iodine in it is rapidly converted to a gaseous form.
Why they change is a question that needs further analysis, but scientists, as mentioned above, suspect it is due to some human activity.
