Cloud study demystifies impact of aerosols

Science Daily  August 1, 2022 Aerosol–cloud interactions have a potentially large impact on climate. The impacts derived from climate models are poorly constrained by observations because retrieving robust large-scale signals of aerosol–cloud interactions is frequently hampered by the considerable noise associated with meteorological co-variability. An international team of researchers (UK, Switzerland, Germany, USA – NASA) disentangled significant signals from the noise of meteorological co-variability using a satellite-based machine-learning approach. Their analysis showed that aerosols from the 2014 Holuhraun effusive eruption in Iceland increased cloud cover by approximately 10%, and this appears to be the leading cause of climate forcing, rather […]
