IfM Buns Talk - Climate Repair: Can We Refreeze the Arctic?

Join us at the Institute for Manufacturing to hear from our Deputy Director, Professor Hugh Hunt, speak on Climate Repair: Can We Refreeze the Arctic?

The talk, starting at 10am, will be followed by cakes and further discussion in the IfM Common Room from 10.45am.

Global warming is on target to exceed 2C by 2050. Arctic sea ice will almost certainly have vanished by then. The AMOC is weakening. Storms, floods and droughts are increasing in severity and frequency. What can we do? Emissions reductions alone are not sufficient, even when supplemented by carbon offsetting (Net Zero). We're left with options to reflect sunlight, by emulating volcanic eruptions with stratospheric aerosols or increasing the reflectivity of clouds. There are even people talking about space reflectors. This talk will outline the activities of the Centre for Climate Repair and the options available to us. Time is running out!

Hugh Hunt is Professor of Engineering Dynamics and Vibration in Cambridge University (Hugh Hunt | Centre for Climate Repair). He has been involved in the field of "geoengineering" since 2010 when the SPICE project began. He is Deputy Director of the Centre for Climate Repair.
