Sentences with phrase «accurate ice core data»

The highly accurate ice core data sets rathr precise dates for three major (and tropical) eruptions for which previous studies by traditional methods of paleogeology gave only poorer approximations.

Not exact matches

Using data from 16 ice cores collected from widely spaced locations around the Antarctic continent, including the South Pole, a group led by Joe McConnell of the Desert Research Institute (DRI) in Reno, Nevada, created the most accurate and precise reconstruction to date of lead pollution over Earth's southernmost continent.

By comparing the atmospheric CO2 increase (note that since CO2 is well - mixed in the atmosphere, a single ice core record can be used as an accurate representation for CO2 - Shakun et al. used the Antarctic EPICA Dome C ice core for CO2 data) to these many different temperature records, Shakun et al. are able to discern whether the CO2 increase led or lagged temperature changes in various different geographic locations, and for the planet as a whole.

Assuming the paleoclimatic evidence (ice core data for example) for the temperature / CO2 correlation is resonably accurate, it is apparent that climate shifts from warming to cooling at CO2 peaks (maximum «forcing») and from cooling to warming at CO2 troughs (minimum «forcing»).
