The International Satellite Cloud Climatology Project (ISCCP) multi‐decadal record of cloudiness exhibits a well‐known global decrease in cloud amounts. This downward trend has recently been used to suggest widespread increases in surface solar heating, decreases in planetary albedo, and deficiencies in global climate models. Here we show that trends observed in the ISCCP data are satellite viewing geometry artifacts and are not related to physical changes in the atmosphere. Our results suggest that in its current form, the ISCCP data may not be appropriate for certain long‐term global studies, especially those focused on trends.”
