Yin and coauthors use the new GFDL CM4 and CM4HR models to consider a series of climate change experiments under the CMIP6 protocol to study characteristics of extreme sea level events and their future evolution in a fully coupled weather, climate, sea level, and storm surge modeling system. They found that even in the absence of global warming, the Gulf Coast is most vulnerable to hurricane-induced storm surge.
A new study helps clarify how past and future coastal sea level changes are related to local winds and large-scale ocean circulation.
Ocean melting of marine-terminating ice sheets poses a profound threat to the global coastal environment with approximately five meters of sea level rise locked up in the ice sheets around the West Antarctic region.
A recent investigation has shown that in the abyssal southeast Indian Ocean the Antarctic Bottom Water (AABW) freshening and warming have changed over the last decade. After a third full repeat of line IO8S in the region, GO-SHIP observations suggest strongly accelerated AABW freshening since 2007.
New research shows that even the longest and highest-quality tide gauge data may underestimate the amount of global average sea level rise that occurred during the 20th century, due to their limited location.
The Pacific Ocean has a significant influence on global mean surface temperature, as recently demonstrated during the 2015/16 El Niño. New research shows a new way to quantify the role of the Pacific Ocean using sea level information rather than traditional sea surface temperature data.
Over the coming decades, the tropical Pacific is likely to experience more extreme sea level swings on timescales of several years. The culprit is a change in the El Niño-Southern Oscillation and its characteristic Pacific wind response, according to a new study using CMIP5 climate change projections.
The coastal sea levels along the Northeast Coast of North America show significant year-to-year fluctuations in a general upward trend. Analysis of long-term tide gauge records along the North American east coast identified an extreme sea-level rise event during 2009–2010. Within this relatively brief two-year period, coastal sea levels north of New York City jumped by up to 128 mm.
