1999). This suggests that either climate model design is missing some important unknown factor, or CLIMAP systematically overestimated the temperatures in the tropical oceans during the last glacial, though there is at present no consistent explanation for why or how this should have happened. Unfortunately cost and difficulty of collecting sediment cores from the open Pacific has limited the availability of samples that might help to confirm or disprove these observations.
1999). This implies either climate model design lacks an essential unknown factor or CLIMAP overestimated tropical ocean temperatures during the last glacial period. There is no clear explanation for this discrepancy. The high cost and difficulty in obtaining sediment cores from the open Pacific have limited the availability of samples that could support or refute these findings.
