Making sense of palaeoclimate sensitivity
Many palaeoclimate studies have quantified pre-anthropogenic climate change to calculate climate sensitivity (equilibrium temperature change in response to radiative forcing change), but a lack of consistent methodologies produces a wide range of estimates and hinders comparability of results. Here we present a stricter approach, to improve intercomparison of palaeoclimate sensitivity estimates...
متن کاملAdvancing Precambrian palaeomagnetism with the PALEOMAGIA and PINT(QPI) databases
State-of-the-art measurements of the direction and intensity of Earth's ancient magnetic field have made important contributions to our understanding of the geology and palaeogeography of Precambrian Earth. The PALEOMAGIA and PINT(QPI) databases provide thorough public collections of important palaeomagnetic data of this kind. They comprise more than 4,100 observations in total and have been es...

متن کاملMonte Carlo methods for Bayesian palaeoclimate reconstruction
In palaeoclimate reconstruction, the natural modelling direction is forwards from climate to sensors to proxy measurements. Statistical methods can be used to invert this direction, making climate inferences from proxy measurements. Among these methods, the Bayesian method would seem to deal best with the substantial epistemic uncertainties about climate, and about its impact on sensors. The ma...
متن کاملPalaeomagnetism of the Bay an Gol Formation , western Mongolia
Oriented samples of the Lov.'er Cambrian Sayan Go! Formation from Salaany Go!, Mongolia, were collected at roughly 5 m stratigraphic intervals for palaeomagnetic analysis. Progressive alternatingfield and thermal demagnetization isolated two magnetic components: a present-field overprint, typically removed by 10 mT fields and -200 °C heating: and a high-coercivity, high-unblocking-temperature (...
