Monday 15 February 2021 (Zoom Meeting): 'Atmospheric Cave Science'. Speaker: Professor Ian Fairchild, School of Geography, Earth and Environmental Sciences, University of Birmingham. Ian's talk will take us from caves and monitoring cave climates over time through the study of stalagmites, to the need for awareness about appropriate room ventilation i.e. CO2 levels. Recently this issue has been covered in the press with respect to Covid-19, and ventilation on aeroplanes and trains, so it is timely and also of interest in relation to underground spaces in the Black Country.
