Quantification of the Greenland ice sheet contribution to Last Interglacial sea level rise [PDF]

, 2012
During the Last Interglacial period (~ 130–115 thousand years ago) the Arctic climate was warmer than today, and global mean sea level was probably more than 6.6 m higher.

A suite of coupled ocean-sea ice simulations examining the effect of regime shift in sea-ice thickness distribution on ice–ocean interaction in the Arctic Ocean [PDF]

Geoscientific Model Development
A major shift in Arctic sea ice occurred in 2007, transitioning from thicker, deformed ice to thinner, more uniform ice with reduced surface roughness. This abrupt change likely altered the dynamic and thermodynamic interactions between sea ice and ocean,

Instantaneous Antarctic ice-sheet mass loss driven by thinning ice shelves [PDF]

, 2019
Recent observations show that the rate at which the Antarctic Ice Sheet (AIS) is contributing to sea level rise is increasing. Increasing ice-ocean heat exchange has the potential to induce substantial mass loss through the melting of its ice shelves ...

Sea ice assimilation into a coupled ocean–sea ice model using its adjoint [PDF]

The Cryosphere, 2017
Abstract. Satellite sea ice concentrations (SICs), together with several ocean parameters, are assimilated into a regional Arctic coupled ocean–sea ice model covering the period of 2000–2008 using the adjoint method. There is substantial improvement in the representation of the SIC spatial distribution, in particular with respect to the position of the

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Pliocene Ice Sheet Modelling Intercomparison Project (PLISMIP) – experimental design [PDF]

Geoscientific Model Development, 2012
During the mid-Pliocene warm period (3.264 to 3.025 million years ago), global mean temperature was similar to that predicted for the next century and atmospheric carbon dioxide concentrations were slightly higher than today.

Future Arctic sea-ice loss reduces severity of cold air outbreaks in midlatitudes [PDF]

, 2016
This is the final version of the article. Available from American Geophysical Union (AGU) via the DOI in this record.The effects of Arctic sea-ice loss on cold air outbreaks (CAOs) in midlatitudes remains unclear.

Modeled Trends in Antarctic Sea Ice Thickness [PDF]

Journal of Climate, 2014
Abstract Unlike the rapid sea ice losses reported in the Arctic, satellite observations show an overall increase in Antarctic sea ice concentration over recent decades. However, observations of decadal trends in Antarctic ice thickness, and hence ice volume, do not currently exist.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Greater Greenland Ice Sheet contribution to global sea level rise in CMIP6

Nature Communications, 2020
The potential contribution of Greenland Ice Sheet to sea level rise in the future is known to be substantial. Here, the authors undertake new modelling showing that the Greenland Ice Sheet sea level rise contribution is 7.9 cm more using the CMIP6 SSP585
