In his talk, Alex Halliday of the Earth Institute will discuss the development of the Earth and the critical need to decarbonize in order to address the climate challenge. Earth’s surface environment has changed dramatically over billions of years of development.  Scientists have been modeling the climate for decades and sounding the alarm about global warming. The evidence now suggests that climate change is going to be worse than most scientists, let alone the wider public, had realized. Carbon dioxide stays in the atmosphere for decades.  Therefore, much of this is effectively irreversible and will worsen without new technologies to remove carbon from the atmosphere. This talk will finish with the challenges for the future of decarbonization, including the technologies and actions that are needed, and some of the reasons to be optimistic.

Alex Halliday is the Director of Columbia University’s Earth Institute.  He joined the Earth Institute in April 2018, after spending more than a decade at the University of Oxford, during which time he was dean of science and engineering.

His scientific achievements have been recognized through numerous awards, including the Murchison Medal of the Geological Society, the Bowen Award and Hess Medal of the American Geophysical Union, the Urey Medal of the European Association of Geochemistry, the Oxburgh Medal of the Institute of Measurement and Control, and a Knighthood for services to science and innovation. He is a Fellow of the UK’s Royal Society and an International Member of the US National Academy of Sciences.

As a professor in Columbia’s Department of Earth and Environmental Sciences, Halliday divides his time between Columbia’s Morningside campus and his geochemistry lab at Lamont-Doherty Earth Observatory. The main focus of his current activities is establishing the new Columbia Climate School.
