Scientists claim that they have found the world’s cleanest climate, free of pollutants produced by human activities, over the Southern Ocean that surrounds Antarctica. In a first-class analysis on bioaerosol composition in the Southern Ocean, Colorado State University researchers identified an atmospheric area which remains unchanged by human activity.
The climate and weather are closely linked, connecting each part of the world to other regions. While the atmosphere increasingly shifts due to human activities, scientists and researchers are trying to locate a corner of Earth that is untouched by humans. Professor Sonia Kreidenweis and her team, however, believed the climate over the Southern Ocean would be the least polluted by humans and pollution from continents across the world.
Researchers found that there was no aerosol particles generated by human activity, like burning fossil fuels, planting some crops, processing fertilizers, in the boundary layer, which feeds the lowest clouds across the Southern Ocean. And the treatment or storage of wastewater from other countries worldwide. Air pollution is caused by aerosols, which are air-suspended solid and liquid particles and gases. The researchers wanted to analyze what was in the air, and where it came from, using airborne bacteria as a diagnostic method to infer the lower atmosphere properties.
