Jaeger, John M. ; Shevenell, Amelia E.
Science is theoretically objective, but biases and paradigms often originate from something as fundamental as field site accessibility, data density, or publication date. Such biases may be at the heart of an enduring paradigm in paleoceanography and paleoclimatology-that changes in cold dense water production in the North Atlantic Ocean forced millennial-scale (<1000 year) global climate changes during the past ∼50,000 years. These changes were first identified in Greenland ice cores >30 years ago. Walczak et al. present compelling data from marine sediments collected in the Northeast Pacific Ocean that add to evidence indicating that the engine of Earth's climate system lies outside the North Atlantic. </p>
