Rising CO2 may increase dangerous weather extremes

London: Meeting the global warming target of 1.5 degrees Celsius may not be enough to limit the damage caused by extreme weather, a study has found. The study, published in the journal Nature Climate Change, demonstrates that higher atmospheric carbon dioxide (CO2) concentrations directly increase temperature and rainfall extremes, meaning there could be dangerous changes in these extremes even if the global mean temperature rise remains within 1.5 degrees Celsius. The study by researchers at the Oxford University and the University of Bristol in the UK highlights the need for climate policy to complement temperature goals with explicit limits on CO2 concentrations.
