Article Summary
Scientists in the US have been cloud-spotting over shipping lanes and have noticed something more interesting than teddy-bear shapes and faces. They have detected that rising steam from passing ships has caused brightening in the clouds which they theorize alters the reflectivity of the cloud and prevents the energy from reaching the Earth. They propose that if this could be achieved artificially via geoengineering it could be an effective defense against global warming.
