The Climate Mapping and Prediction Project, or CLIMAP, was the first interdisciplinary effort to map past global climates. This resulted in maps displaying the size and location of LGM ice sheets covering 25% of the Earth's surface, as well as ocean temperatures on the planet's lower surface, with exceptions in low latitudes where some warming could have occurred. Although this project was groundbreaking in the field, some of its findings were met with skepticism. Other climatologists have considered the mapping of ice sheets to be inaccurate with respect to: their extent at relatively low latitudes, their presence in some marine areas, and their overall thickness. Further research proved that these errors were true to some extent in certain regions of the maps. Regardless, CLIMAP marked a turning point in interdisciplinary data modeling, and their findings became a cornerstone of the field. In the 1980s, the Cooperative Holocene Mapping Project, or COHMAP, took a step forward from CLIMAP and aimed to create a more accurate map of climate from the Last Glacial Maximum to the present based on combined proxy data including pollen levels and 14C records. They succeeded, and the accuracy and complexity of LGM climate modeling has improved since then. Current articles, such as the Last Glacial Maximum published in Science magazine
