In 201718, 2,500 volunteers counted tiny pores on ginkgo leaves to study the ancient atmosphere; 24,000 classifications helped process the images

Ginkgo trees, which have existed for millions of years, provide valuable information on historical carbon dioxide levels. Researchers employ citizen volunteers to count leaf pores, enhancing the study's efficiency. Initial test phases revealed varying accuracy levels among volunteers but still yielded useful data. Methods to correct classifications have improved the reliability of the results significantly. This collaborative effort fosters public engagement with climate science and enhances research productivity.
