Australian scientists seek to understand how non-carbon aerosolised particles affect global temperatures Australian scientists are studying air pollution and cloud formation in Antarcticain an effort to understand how non-carbon aerosolised particles impact on global temperatures. It’s the first comprehensive study of the composition and concentration of aerosols in the Antarctic sea ice area, a region that influences cloud formation and weather patterns for much of the southern hemisphere. The impact that aerosolised particles have on the global climate is one of the biggest unknowns in climate science, said a CSIRO scientist, Dr Ruhi Humphries..
