Cafe Scientifique: Public discussion on climate engineering Friday 8 March 7-9pm, Norwich

Science, politics and public perceptions of climate engineering Together with UEA colleagues, IAGP Project Manager Naomi Vaughan will lead a public discussion into geoengineering on Friday 8 March, 7-9pm. The event will take place at The Forum, Cafe Marzano, Norwich, NR2 1TF and is open to the public. Attendance is free. Read more and sign up to attendAbout Cafe Scientifique

How effective is marine cloud brightening in reducing solar radiation?

New IAGP paper published in Atmospheric Chemistry and Physics The effects of timing and rate of marine cloud brightening aerosol injection on albedo changes during the diurnal cycle of marine stratocumulus clouds Certain geoengineering schemes have been proposed to decrease the amount of solar radiation reaching the Earth’s surface, creating a cooling effect that could potentially ameliorate future greenhouse gas driven warming. One such scheme, known as marine-cloud brightening, aims to brighten low cloud, generating a negative radiative forcing from the cloud albedo increase.
