Ice sheets may have reached the Equator in the late Proterozoic era (600–800 Myr ago), according to geological and palaeomagnetic studies, possibly resulting in a ‘snowball Earth’. But this period was a critical time in the evolution of multicellular animals, posing the question of how early life survived under such environmental stress. Here we present computer simulations of this unusual climate stage with a coupled climate/ice-sheet model. To simulate a snowball Earth, we use only a… 

Climatic cycles during a Neoproterozoic “snowball” glacial epoch

The profound glaciations of the Neoproterozoic Cryogenian period (ca. 850–544 Ma) represent an extreme climatic mode when, it is claimed, Earth was fully or almost completely covered with ice for

CO2 levels required for deglaciation of a “near‐snowball” Earth

Geologic evidence suggests that in the Late Neoproterozoic (∼600 Ma) almost all land masses were glaciated, with sea‐level glaciation existing even at the equator. A recent modeling study has shown

Climate Dynamics in Deep Time: Modeling the “Snowball Bifurcation” and Assessing the Plausibility of its Occurrence

The apparently global scale glaciation events that occurred during the Neoproterozoic era, in the interval from 750 Ma to 550 Ma, represent a significant challenge to our understanding of climate

A review of Neoproterozoic climate modeling studies

Over the past decade, a number of climate modeling studies have examined the possibility of simulating low-latitude glaciation using Neoproterozoic boundary conditions. Many of the studies undertaken

A ‘snowball Earth’ climate triggered by continental break-up through changes in runoff

Assessment of the palaeogeographic changes preceding the Sturtian glacial period and the long-term evolution of atmospheric carbon dioxide levels using the coupled climate–geochemical model GEOCLIM indicates that tectonic changes could have triggered a progressive transition from a ‘greenhouse’ to an ‘icehouse” climate during the Neoproterozoic era.

The snow/ice instability as a mechanism for rapid climate change: A Neoproterozoic Snowball Earth model example

Paleoclimate data increasingly suggest the likelihood of abrupt transitions due to instabilities in the climate system. Several previous studies offer support for the snow/ice instability mechanism

Subtropical clouds stabilize near-Snowball Earth states

Here, we study a deep-time extreme climate of Earth as an example of the cold limit of the habitable zone. Geological evidence indicates near-global ice cover during the Neoproterozoic (1000 – 541

Climate‐Ice Sheet Simulations of Neoproterozoic Glaciation Before and After Collapse to Snowball Earth

Geologic evidence of tropical sea level glaciation in the Neoproterozoic is one of the cornerstones of the Snowball Earth hypothesis. However, it is not clear during what part of the Snowball Earth

Snowball Earth: A thin-ice solution with flowing sea glaciers

[1] The late Neoproterozoic era, ∼600–800 Myr ago, was marked by at least two intervals of widespread cold that left glacial deposits at low paleolatitudes. Both “Snowball” solutions with global ice



The Pangean ice age: studies with a coupled climate-ice sheet model

Abstract Application of an ice sheet model developed for the Pleistocene to the extensive Carboniferous glaciation on Gondwana yields an ice sheet which has several features consistent with

Terminating the 100 kyr ice age cycle

We report a simulation of the most recent 100,000-year glaciationdeglaciation cycle of the late Pleistocene ice age, a simulation that delivers an ice sheet chronology that is in close accord with

GCM simulations of snowball earth conditions during the Late Proterozoic

In order to simulate the Snowball Earth conditions that may have existed during the late Proterozoic we have conducted a series of GCM simulations using a simple 50‐meter slab ocean, a reduced solar

GCM response to Late Precambrian (∼590 Ma) ice—covered continents

Recent coupled energy balance/ice sheet modeling studies indicate that ice‐covered continents can be simulated for the Late Precambrian with 6% solar constant reduction. We examine the ocean mixed

Impact of thermomechanical ice sheet coupling on a model of the 100 kyr ice age cycle

Simulations of the most recent 100 kyr glaciation-deglaciation cycle of the late Pleistocene Ice Age are presented which feature a newly constructed thermomechanically coupled three-dimensional ice

A neoproterozoic snowball earth

Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial deposits in Namibia, combined with estimates of thermal subsidence history, suggest that biological productivity

Milankovitch cycles and carboniferous climate

Cyclical Permo-Carboniferous sea level fluctuations have long been linked to glacial-interglacial fluctuations on Gondwanaland. Similar to the Pleistocene, such fluctuations may in turn have been

Seasonal snowline instability in a climate model with realistic geography: Application to carboniferous (∼300 MA) glaciation

Instabilities in the climate system are possible mechanisms for shifting the climate from one stable mode to another. One such instability involves the nonlinearity associated with snow-albedo

Effect of decreased solar luminosity on late Precambrian ice extent

The latest Precambrian (∼0.57 Ga) was marked by extensive glaciation on a supercontinent. Ice cover may have been in lower latitudes than during the Pleistocene. Deglaciation and breakup of the

Simulations of continental ice sheet growth over the last glacial-interglacial cycle: Experiments with a one-level seasonal energy balance model including realistic geography

A global, two-dimensional, one-level seasonal energy balance model (linear in temperature) is asynchronously coupled to vertically integrated ice-flow models (which depend on latitude and longitude)
