Baasim use to be a little white cloud but turned brown after inhaling too much aerosol paint. Baasim is addicted to these aerosols and therefore always smiling underneath all the paint caked up on his face. Aerosols are tiny particles that are suspended in the air and create a general cooling effect. Baasim prefers to stay cool and therefore won’t give up his habit easily. Brown clouds, like Baasim, contain dark aerosols – these particles absorb solar energy and then release it to the surrounding air as heat – Baasim is going to leave his carbon footprint behind. Baasim talks slowly.
