Nonstationary Synchronization of Equatorial QBO with SAO in Observations and a Model [PDF]

open access: yes, 2009
It has often been suggested that the period of the quasi-biennial oscillation (QBO) has a tendency to synchronize with the semiannual oscillation (SAO). Apparently the synchronization is better the higher up the observation extends. Using 45 yr of the 40-

The effects of changing solar activity on climate: contributions from palaeoclimatological studies

open access: yesJournal of Space Weather and Space Climate, 2012
Natural climate change currently acts in concert with human-induced changes in the climate system. To disentangle the natural variability in the climate system and the human-induced effects on the global climate, a critical analysis of climate change in ...

Climate, fire disturbance regime, and vegetation response of the past 2500 years for central Nova Scotia

open access: yesEcosphere, 2023
The interaction between climate change and disturbances affects forest composition and dynamics, but most of our empirical knowledge comes from short‐term studies of the past century.

Decadal and Bi-Decadal Periodicities in Temperature of Southern Scandinavia: Manifestations of Natural Variability or Climatic Response to Solar Cycles?

open access: yesAtmosphere, 2021
Nine proxies of temperature over the last 225–300 years in Southern Fennoscandia (55–63° N) were analyzed. Seven reconstructions of the mean growing season temperatures were obtained by dendroclimatological methods. Reconstructions of spring temperatures

Decoupled lake history and regional moisture availability in the middle elevations of tropical Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2016
During the Holocene, most of the climatic variability in the tropics has manifested through changes in the precipitation regime. Although there is relatively a large amount of information on this climatic variability from the lowlands during this time ...

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

open access: yesJournal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The Mid-Pleistocene Transition induced by delayed feedback and bistability [PDF]

open access: yes, 2018
The Mid-Pleistocene Transition, the shift from 41 kyr to 100 kyr glacial-interglacial cycles that occurred roughly 1 Myr ago, is often considered as a change in internal climate dynamics.
