Where in heaven's name did an Avalon Spouter get the silly notion that climate scientists have only 5 ice core samples to study for evidence of changes in atmospheric gasses? NASA and the EPA state that scientists have been collecting samples for years from various locations, including Antarctica, Greenland, and North America. The samples are stored in the National Science Foundation's Ice Core Facility in Colorado. The facility records some 17,000 meters of the samples in the collection. Rows and rows of the samples - 100's if not 1000's - can be viewed by googling "NCF-ICF".
