Ship Clouds above the Pacific Ocean


This impressive image shows the legacies of ships in the atmosphere. The white traces of clouds have an effect on the natural clouds: Particles of exhaust gas (aerosols) increase the reflectivity of the clouds which means they can absorb more water. This leads to a reduced precipitation. Even though the use of fossil fuels of ships only accounts for a relatively small part of the changing atmosphere, this image gives an idea which impacts human actions can have on nature.
