TL;DR: The potential contribution to eustatic and regional sea level from a rapid collapse of the West Antarctic Ice Sheet is reassessed and it is found that previous assessments have substantially overestimated its likely primary contribution.

TL;DR: In Paris, France, December 2015, the Conference of the Parties (COP) to the United Nations Framework Concerning on Climate Change (UNFCCC) invited the Inter- governmental Panel on Climate change (IPCC).

TL;DR: In this paper, the authors present estimates of the altimetry-based global mean sea level (average variance of 3.1 +/- 0.3 mm/yr and acceleration of 0.1 mm/r2 over 1993-present), as well as of the different components of the sea level budget over 2005-present, using GRACE-based ocean mass estimates.

TL;DR: In this paper, the authors present maps of twenty-first century local relative sea-level (RSL) change estimates based on an ensemble of coupled climate model simulations for three emission scenarios.

TL;DR: A 20th-century GMSL reconstruction computed using an area-weighting technique for averaging tide gauge records that both incorporates up-to-date observations of vertical land motion (VLM) and corrections for local geoid changes resulting from ice melting and terrestrial freshwater storage and allows for the identification of possible differences compared with earlier attempts is presented.
