Abstract: CLIVASH2K is a PAGES 2K Network project investigating Climate Variability in Antarctica and the Southern Hemisphere over the past 2000 years. Founded as part of the third phase of the PAGES 2`k Network, it expands upon the efforts of the former regional groups which aimed to spatially reconstruct important state variables for the climate system. The focus of CLIVASH2K is understanding the drivers of climate variability, and incorporating climate reconstructions from Antarctica, the sub-Antarctic and the wider Southern Hemisphere to explore the regional to hemispheric teleconnections and associated models of variability.

Abstract: Sea-level projections depend upon an accurate understanding of the relationship between climate forcing and the spatio-temporal evaluation of sea-level , as well as its different driving mechanisms. Yet this understanding is limited by the timescale of the instrumental data; most available records contain data only from the 20th and 21st centuries (Horton et al.2018) .Complementing instrumental data, geological records can provide valuable archives of the sea-level response to past climate variability, including during periods of higher global mean temperatures (Dutton et al.2015) , and can help improve estimates of the relationship between future temperature and sea-level change (Kopp et al.2016) However, current ties between geological sea-level records and future projections are often vague and tentative; improved interconnections between the two sub-disciplines are thus a key to progress (Horton et al.2018).

Keywords: Storms, Insights, historical and Paleo record
Abstract: The potential for increased impacts from coastal storms is among the most concerning aspects related to future climate warming. Increasing impacts from these events can be broadly related to two factors. Firstly, it is expected that as relative sea level (RSL) continues to rise through 2300, significant regions, including major metropolitan areas, will be exposed to inundation without requiring any increase in the strength of storms (e.g Garner et al 2017) .Secondly, increased intensity and frequency of the most extreme events is possible. Together, these two causative actors indicate that coastal flooding is likely to double by 2050 due to the combined effect of RSL rise and storm surge (Vitousek et al.2017).The study of land-falling coastal storms under future climate scenarios accelerated in the aftermath of Hurricane Sandy (2012) and has been under the spotlight again after Typhoon Haiyan (2013), and Hurricanes Florence and Michael and Typhoon Mangkhut (2018).

Abstract: Since the 19th century, it has been recognized that spatially variable sea-level changes result from changes in surface loading, which perturb Earth’s gravity field and the elevation of the crust (Jamieson 1865;Woodward 1888) .Several decade ago, this connection was formalized in a gravitationally self-consistent theory of sea-level change (Farrell and Clark 1976), which for the first time, accounted for both solid Earth deformation and the gravitational attraction of water toward itself, thus capturing the perturbations in both the sea floor and the sea surface that accompany ice melt.

Abstract: The Last interglacial (LIG, 129 to 116 kyr BP; thousands of years before present, where present is defined as 1950 CE) is recognized as an important time interval for testing our knowledge of interactions between climate and ice sheets in warm climate states that led to deglaciation of the Greenland and potentially western Antarctic ice sheets. The LIG was already recognized as an important time period of relevance for the future in the First Assessment Report of the Intergovernmental Panel on Climate Change (IPCC; Folland et al1990) .It gained more prominence since the Fourth and Fifth Assessment reports (IPCC AR4 and AR5) with new reconstructions highlighting that global mean sea level was ~6.9 m higher than present for several thousand years (Dutton et al2015) .Questions remain regarding the contributi0n of eh Greenland ice sheet to this highstand, as well as when and by how much temperatures peaked in the Northern Hemisphere high latitudes.

Abstract: Past warm intervals such as the mid-Piacenzian Warm Period (mPWP: 3.264-3.025 million years ago) or the Last interglacial (LIG:129-116 thousand years (kr) ago ) have been widely studied to constrain past sea-level changes ( e.g Sutter et al. 2016; de Boer et al.2017).Also, those intervals are studied for process understanding of the Earth warming (e.g. DeConto and Pollard 2016) Geological evidence indicates that global mean sea level during the mPWP and LIG were likely to be up to 20 m or more (Miller et al.2012) and 6-9 m (Dutton et al.2015) relative to the present, respectively. This reflects the cumulative (a) synchronous contribution of the Greenland and Antarctic ice sheet (GrIS and AIS). Numerical ice-sheet models are the only means to determine their individual contribution to past sea-level changes.

Abstract: Local sea-level reconstructions have been the foundation for understanding past ice-sheet behaviour, especially records spanning the last deglaciation and past interglacial periods. Linking the evolution of local sea level to global mean sea level, which is also related to ice-volume changes, requires a correction for any uplift or subsidence of the field site that has occurred since the sea-level record was formed. Such vertical movement s can occur due to tectonic crustal deformation, glacial isostatic adjustment deformation, glacial isostatic adjustment GIA, e.g., Milne et al) erosion, or sediment loading (e.g., Ferrier et al. this issue)

Abstract: The primary aim of the PALSEA (PALeo constraints on SEA level rise) working group is to promote and improve the use of constraints from observations and modelling of past sea-level changes and ice-sheet extent to better inform projections of future sea-level change. Glacial isostatic adjustment (GIA)-the deformational, gravitational and rotational expense of the Earth to past ice-sheet evolution-plays an important role in reaching this objective in several respects.

Abstract: Quantifying the sensitivity of the Antarctic ice sheet (AIS) to increasing ocean temperatures is central to improving projections of global sea-level rise. Capron et al (2014) compiled strong evidence of a Southern Ocean Sea-surface temperature anomaly of up to + 3.9 ± 2.8°C 125,000 years ago (125 kyrBP) compared to the present, and sea-level indicators for the last interglacial (LIG; around 129 to 116 kyr BP) suggest that this was the last time that global mean sea level (GMSL) was substantially higher than present (Dutton et al.2015).This strongly suggests that pinning down the responses of the AIS during the LIG should insight into the last time the AIS was substantially smaller than today.

Abstract: The Greenland ice sheet is the last surviving ice sheet of what was the order-of-magnitude larger extent of North Hemisphere ice sheets at the last glacial maximum about 21, 000 years ago. As such, its responses to ongoing and future global warming represent a major concern regarding its impact on global sea-level. In the last decade, the application of 10Be exposure dating along with “threshold” lakes dated by 14C now constrain the timing of when the Greenland ice sheet retreated to a smaller-than-present extent in the Holocene. Likewise, radiogenic isotopic tracers of silt-size particles combined with ice-rafted debris and subglacial bedrock cosmogenic isotopic concentration can provide evidence of how small the Greenland ice sheet may have been in prior interglacial periods. These data can provide important constraints on the sensitivity of the Greenland ice sheet to paleoclimates similar to, or warmer than, present.

Abstract: Geological sea-level reconstructions are developed using sea-level proxies, which formed in relation to the past position of sea level and include isotopic, sedimentary, geomorphic, archaeological, and fixed biological indicators, in addition to coral reefs and microatolls, as well as wetland flora and fauna. The past position of sea level over space and time is defined by what are termed sea-level index or limiting points.

Abstract: Relative sea level (RSL) varies across space (local to global) and through time (minutes to millennia). Proxy-based reconstructions provide insight into the physical processes that govern these spatio-temporal patterns of RSL change, including the distribution of land-based ice-melt, glacio-isostatic adjustment (GIA) and ocean-atmosphere dynamics. They can also help to constrain projections of future RSL change under climate change scenarios. Reconstructions of late Holocene(Roughly) the past 3000 years) RSL changes are of limited use as direct analogues for future changes in which the magnitude of forcing will be greater and faster than climate variability during this period. Analogues for future RSL change are more likely to be found (for example) in the Pliocene (Miller et al. This issue) or the Last interglacial (Dutton and Barlow, this issue). Nevertheless, the late Holocene is a key period for reconstructing RSL for the following reasons (e.g .Kemp et al. 2015).
