Dr JAMES HANSEN is known as the ‘Father of Climate Change Awareness’, having first warned the US Congress of the effects of anthropogenic climate change back in 1988, while working for the National Aeronautics and Space Administration (NASA). He is regarded as one of the world’s most eminent climate scientists. Dr MAKIKO SATO has devoted her career to researching our global climate. She has spent the last few decades working closely with Dr Hansen at NASA’s Goddard Institute for Space Studies (GISS) after obtaining her PhD in physics. Dr RETO RUEDY is a mathematician working as a Scientific Programmer/Analyst at GISS. He joined the team that developed the GISS climate model in 1976, and has been in charge of the technical aspects of the GISS temperature analysis for the past 25 years.
