 E-Mail Credit: Kathy Kasic/Brett Kuxhausen, Montana State University Centuries-old smoke particles preserved in the ice reveal a fiery past in the Southern Hemisphere and shed new light on the future impacts of global climate change, according to a research led by Harvard University and a group of international researchers from the Desert Research Institute in Nevada and the University of Hong Kong, etc. recently published in Science Advances. Up till now, the magnitude of past fire activity, and thus the amount of smoke in the preindustrial atmosphere, has not been well characterised, said Pengfei LIU, a former graduate student and postdoctoral fellow at the Harvard John A Paulson School of Engineering and Applied Sciences (SEAS) and first author of the paper. These results have importance for understanding the evolution of climate change from the 1750s until today, and for predicting future climate.
