DESCRIPTION:The CLOUD experiment was proposed to determine whether cosmic 
 rays have a strong enough effect on clouds to influence the Earth's climat
 e. To achieve this requires a better understanding of the atmospheric aero
 sol particles that form the seeds for cloud droplets. Aerosol concentratio
 ns have changed substantially over the industrial era and as a result the 
 effect of aerosols on clouds causes the largest uncertainty in projections
  of global temperature changes for the coming century. CLOUD measurements 
 can be used to determine the rate at which cloud seeds form in the atmosph
 ere in climate models\, and this should help to constrain climate change p
 redictions in the future. In addition\, the role of ions from cosmic rays 
 in cloud seed formation is now better understood. I will introduce the sci
 ence\, describe the experiment and related atmospheric modelling\, and out
 line the important advances in this field CLOUD has published in the last 
 two years.
