“"So should we be using climate models? We are climate scientists from Australia’s Centre of Excellence for Climate Extremes, and we believe the answer is a firm yes."”

“"Before industrial times, CO₂ levels in the atmosphere were 280 parts per million. So a doubling of CO₂ will occur at 560 parts per million."”

“"Climate models are one of many tools scientists use to understand how the climate changed in the past and what it will do in future."”
