Critical insolation–CO2 relation for diagnosing past and future glacial inception

  title={Critical insolation–CO2 relation for diagnosing past and future glacial inception},
  author={Andrey Ganopolski and Ricarda Winkelmann and Hans Joachim Schellnhuber},
The past rapid growth of Northern Hemisphere continental ice sheets, which terminated warm and stable climate periods, is generally attributed to reduced summer insolation in boreal latitudes. Yet such summer insolation is near to its minimum at present, and there are no signs of a new ice age. This challenges our understanding of the mechanisms driving glacial cycles and our ability to predict the next glacial inception. Here we propose a critical functional relationship between boreal summer… 
Glacial Inception in Marine Isotope Stage 19: An Orbital Analog for a Natural Holocene Climate
Present-day climate would be susceptible to glacial inception if greenhouse gas concentrations were as low as they were at the end of MIS 19c, a proxy for a contemporary climate system unaffected by humans.
Roles of insolation forcing and CO2 forcing on Late Pleistocene seasonal sea surface temperatures
Investigating changes in alkenone-based annual mean and Globigerinoides ruber Mg/Ca-based summer sea surface temperatures in the East China Sea and their linkages to climate forcing over the past 400,000 years implies the need to consider proxy seasonality and seasonal climate variability to estimate climate sensitivity.
Climate science: Earth's narrow escape from a big freeze
It is confirmed that Earth has just missed entering a new glacial period, and is unlikely to enter one for another 50,000 years, and in the absence of human perturbations to the climate system, the present interglacial would persist for tens of thousands of years.
Simulating Marine Isotope Stage 7 with a coupled climate–ice sheet model
Abstract. It is widely accepted that orbital variations are responsible for the generation of glacial cycles during the late Pleistocene. However, the relative contributions of the orbital forcing
Simulation of climate, ice sheets and CO 2 evolution during the last four glacial cycles with an Earth system model of intermediate complexity
Abstract. In spite of significant progress in paleoclimate reconstructions and modelling of different aspects of the past glacial cycles, the mechanisms which transform regional and seasonal
Global glacier dynamics during 100 ka Pleistocene glacial cycles
Abstract Ice volume during the last ten 100 ka glacial cycles was driven by solar radiation flux in the Northern Hemisphere. Early minima in solar radiation combined with critical levels of
Marine carbon cycle evolution in the eastern equatorial pacific over the last deglaciation
Although the glacial-interglacial climate cycles of the late Pleistocene were very likely paced by changes in solar insolation, the full amplitude of these climate cycles was only achieved with the
The “missing glaciations” of the Middle Pleistocene
Abstract Global glaciations have varied in size and magnitude since the Early–Middle Pleistocene transition (~773 ka), despite the apparent regular and high-amplitude 100 ka pacing of
Interglacials of the Quaternary defined by northern hemispheric land ice distribution outside of Greenland
This so-called Mid-Pleistocene Transition via model-based deconvolution of benthic δ18O is investigated, redefining interglacials by lack of substantial northern hemispheric land ice outside of Greenland, finding that in 67%, 88% and 52% of the obliquity cycles during the early, middle and late Quaternary, respectively, a glacial termination is realized leading to irregular appearances of new interglacialials.
Modeled Influence of Land Ice and CO2 on Polar Amplification and Paleoclimate Sensitivity During the Past 5 Million Years
Polar amplification and paleoclimate sensitivity (S) have been the subject of many paleoclimate studies. While earlier studies inferred them as single constant parameters of the climate system, there


Insolation-driven 100,000-year glacial cycles and hysteresis of ice-sheet volume
It is shown that insolation and internal feedbacks between the climate, the ice sheets and the lithosphere–asthenosphere system explain the 100,000-year periodicity of glacial cycles.
Determining the natural length of the current interglacial
terglacials can be used to draw analogies with the present, provided their duration is known. Here we propose that the minimum age of a glacial inception is constrained by the onset of bipolar-seesaw
The role of orbital forcing, carbon dioxide and regolith in 100 kyr glacial cycles
Abstract. The origin of the 100 kyr cyclicity, which dominates ice volume variations and other climate records over the past million years, remains debatable. Here, using a comprehensive Earth system
A movable trigger: Fossil fuel CO2 and the onset of the next glaciation
The initiation of northern hemisphere ice sheets in the last 800 kyr appears to be closely controlled by minima in summer insolation forcing at 65°N. Beginning from an initial typical interglacial
Glacial CO2 cycle as a succession of key physical and biogeochemical processes
During glacial-interglacial cycles, atmospheric CO 2 concentration varied by about 100 ppmv in amplitude. While testing mechanisms that have led to the low glacial CO 2 level could be done in
The timing of Pleistocene glaciations from a simple multiple-state climate model
The Earth's climate over the past million years has been characterized by a succession of cold and warm periods, known as glacial–interglacial cycles, with periodicities corresponding to those of the
Eight glacial cycles from an Antarctic ice core
The Antarctic Vostok ice core provided compelling evidence of the nature of climate, and of climate feedbacks, over the past 420,000 years. Marine records suggest that the amplitude of climate
Simulation of long-term future climate changes with the green McGill paleoclimate model: the next glacial inception
The multi-component “green” McGill Paleoclimate Model (MPM), which includes interactive vegetation, is used to simulate the next glacial inception under orbital and prescribed atmospheric CO2
Individual contribution of insolation and CO2 to the interglacial climates of the past 800,000 years
The individual contributions of insolation and greenhouse gases (GHG) to the interglacial climates of the past 800,000 years are quantified through simulations with a model of intermediate complexity
Evolution of Ocean Temperature and Ice Volume Through the Mid-Pleistocene Climate Transition
The results suggest that the MPT was initiated by an abrupt increase in Antarctic ice volume 900 thousand years ago, and reveal the contributions of ice volume and temperature to glacial cycles, suggest when and why the Mid-Pleistocene Climate Transition occurred, and clarify how carbon is lost from the ocean-atmosphere during deglaciations but also changes because of ocean circulation.
