The Climate Mapping and Prediction Project, or CLIMAP, was the first interdisciplinary effort to map previous global climates. The result is maps showing the size and location of LGM ice sheets covering 25% of Earth's land surface and lower surface ocean temperatures planetwide, with exceptions at lower latitudes where some warming may have occurred. Although this project was revolutionary for the field, some of its findings were met with skepticism. Other climate scientists felt that the mapping of ice sheets was inaccurate regarding: their extent to relatively low latitudes, their presence in some marine areas, and their overall thickness. Further research has shown these errors to be true to some extent in some regions of the maps. Regardless, CLIMAP represented a turning point for interdisciplinary data modeling, and their findings have become the cornerstone of the field. In the 1980s, the Cooperative Holocene Mapping Project, or COHMAP, went a step further than CLIMAP and aimed to create a more accurate mapping of climate from the Last Glacial Maximum to the present, drawing on combined proxy data including levels of pollen 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 the journal Science
