Maintenance of the great late Ediacaran ice age [PDF]
Nature CommunicationsGeological records witness extensive glaciations in the late Ediacaran, ranging from ~580 to 560 Ma or younger. However, the explanation of maintenance for this regionally diachronous and globally continuous glacial epoch is still unclear.

Large equatorial seasonal cycle during Marinoan snowball Earth. [PDF]
Sci Adv, 2020 © 2020 The Authors. In the equatorial regions on Earth today, the seasonal cycle of the monthly mean surface air temperature is 1 m) sand wedges were found near the paleoequator in the Marinoan glaciogenic deposits at ∼635 million years ago, indicating a

Initiation of a Marinoan Snowball Earth in a state-of-the-art atmosphere-ocean general circulation model [PDF]
Climate of the Past, 2011 We study the initiation of a Marinoan Snowball Earth (~635 million years before present) with the state-of-the-art atmosphere-ocean general circulation model ECHAM5/MPI-OM. This is the most sophisticated model ever applied to Snowball initiation.

When the Earth goes white: the Snowball Earth attractor [PDF]
, 2022 Using an intermediate complexity climate model we investigate the so-called snowball Earth transition. For certain values (including its current value) of the solar constant, the climate system allows two different stable states: one of them is the ...

A conceptual model of oceanic heat transport in the Snowball Earth scenario [PDF]
Earth System Dynamics, 2016 Geologic evidence suggests that the Earth may have been completely covered in ice in the distant past, a state known as Snowball Earth. This is still the subject of controversy, and has been the focus of modeling work from low-dimensional models up to ...

Climate and ocean circulation in the aftermath of a Marinoan snowball Earth [PDF]
Climate of the Past, 2022 When a snowball Earth deglaciates through a very high atmospheric CO2 concentration, the resulting inflow of freshwater leads to a stably stratified ocean, and the strong greenhouse conditions drive the climate into a very warm state.

Climate and ocean circulation changes toward a modern snowball Earth [PDF]
Climate of the PastIt has been hypothesized that the Earth may have experienced snowball events in the past, during which its surface became completely covered with ice. Previous studies used general circulation models to investigate the onset and climate of such snowball ...

Geosciences, 2012 Evidence based on molecular clocks, together with molecular evidence/biomarkers and putative body fossils, points to major evolutionary events prior to and during the intense Cryogenian and Ediacaran glaciations. The glaciations themselves were of global

Tonian Low‐Latitude Marine Ecosystems Were Cold Before Snowball Earth
Geophysical Research Letters, 2023 Precambrian marine carbonate strata are commonly assumed to have formed in warm‐water carbonate factories due to the temperature dependence of non‐skeletal carbonate precipitation rates.

Eurypsychrophilic acidophiles: From (meta)genomes to low-temperature biotechnologies
Frontiers in Microbiology, 2023 Low temperature and acidic environments encompass natural milieus such as acid rock drainage in Antarctica and anthropogenic sites including drained sulfidic sediments in Scandinavia.
