Ice sheets
11 studies1 discovery
Ice-sheet and glacier papers measure mass, melt, iceberg drift or sea-ice coupling for Greenland, Antarctica or mountain ice.
Ice is the slow climate system that sets long-term sea level.

What we know
- This library holds 11 empirical papers on ice sheets with measured outcomes rather than reviews.
- A 150 m Greenland bed and fjord map raises sea-level potential by 7 cm and shows 30–100% more glaciers can meet warm Atlantic Water.
- A recently calved iceberg dumped meltwater and triggered a bloom, while a decades-grounded berg barely changed nearby waters.
- BAM, SAM, and PSA polarities rearrange Antarctic precipitation, with PSA1 explaining ~40% of daily variability in West Antarctica.
- Losing Arctic sea ice in a +2 °C world adds winter snow to Greenland but more than offsets it with extra summer melt.
Largest unresolved question
A melt-season ANN or a giant-iceberg track is not a committed multi-metre sea-level number.
Common misconceptions
If air warms 1 °C, ice loss is linear and immediate.
SMB, dynamics, ocean melt and circulation patterns are nonlinear and delayed.

Timeline
How understanding moved
Study years are when the paper was published. Evidence edits are dated changes to this page's claims. Explanations are when PaperFren added a Discovery — not a claim that the science happened that day.
Change log
What changed
Dated edits to this page's evidence: studies added or removed from a claim, claims added or withdrawn, and new explanations tagged here. Coverage edits are distinct from reviewed research changes and corrections. Dates record PaperFren updates; study publication dates appear in the timeline.

- Greenland’s hidden fjord floors in BedMachine v3
A 150 m Greenland bed and fjord map raises sea-level potential by 7 cm and shows 30–100% more glaciers can meet warm Atlantic Water.
- SH circulation patterns shape Antarctic snowfall
BAM, SAM, and PSA polarities rearrange Antarctic precipitation, with PSA1 explaining ~40% of daily variability in West Antarctica.
- How Bølling warming and ice saddles fed MWP1a
North American ice-sheet ensembles show saddle collapse and Bølling warming can supply several meters of Meltwater Pulse 1a in 340 years.
- Atmospheric rivers supply ~13% of Antarctic snow
Rare atmospheric rivers deliver about 13% of Antarctic precipitation and explain more than a third of its year-to-year swings.
- A buried Antarctic lake drained through hydrofracture
Ground-penetrating radar caught a buried meltwater lake draining through vertical fractures at an East Antarctic ice-shelf grounding zone.
- Small icebergs add a lot of Greenland fjord freshwater
High-resolution UNet mapping finds far more small icebergs than Sentinel-2 thresholding, raising Sermilik meltwater estimates toward ~2000 m³ s−1.
- Why two giant icebergs fertilize the ocean differently
A recently calved iceberg dumped meltwater and triggered a bloom, while a decades-grounded berg barely changed nearby waters.
- Less Arctic sea ice both snows and melts Greenland
Losing Arctic sea ice in a +2 °C world adds winter snow to Greenland but more than offsets it with extra summer melt.

- Neural nets map CMIP6 weather into Greenland melt
ANNs trained on CESM2 translate CMIP6 atmospheres into Greenland surface-melt increases of about 79–264% by 2100 depending on SSP.
- Soft-bed glaciers show a hydrology continuum
Seasonal ice-speed patterns on Icelandic and Norwegian glaciers reveal mixed, not purely channelized or distributed, soft-bed drainage.
- Proglacial lakes speed Greenland outlet glaciers
Lake-terminating Greenland outlet glaciers flow much faster near their fronts than otherwise similar land-terminating glaciers.
