A study published in Science notes that water flowing from the Atlantic Ocean into the Arctic is warmer than it's been in 2,000
years. Scientists believe that this increased heat input has far-reaching consequences to life on Earth. U.S. and European scientists studied the Fram Strait branch of the North Atlantic Current, the ocean current that carries heat north from the tropics. By studying tiny-shelled organisms called foraminifera, found deep in the ocean floor, they could chart temperatures going back 2,000 years. From their findings, scientists reported that the water has warmed about 2° C since the late 1800s. An additional on-going study has been monitoring atmospheric carbon dioxide at the Mauna Loa Observatory. Atmospheric carbon dioxide contributes to the retention of radiation in Earth's atmosphere. What impact does the Mauna Loa data have on the study published in Science? A) It refutes the study. B) It adds support to the study. C) It has little impact of the study. D) It confirms the accuracy of the study.
