Both groups have studied ice cores as deep as two miles, establishing climate chronology from changes in layering thickness and measuring historic temperature data from varying ratios of oxygen isotopes in entrapped air bubbles. (thenewamerican.com)
Dr Paul Durack, an Australian oceanographer from the U.S. Department of Energy's (DOE) Lawrence Livermore National Laboratory, suggests that the underestimation has been due to scarce historic temperature data of the Southern Ocean. (techtimes.com)
This is about the release of historic temperature data for crying out loud, not Cold Fusion research data some equally commercially valuable data. (climateaudit.org)
