Global mean sea level has experienced an unabated rise over the 20th century. This observed rise is due to both ocean warming and increasing continental freshwater discharge. We estimate the net ocean mass contribution to sea level by assessing the globa
Reconstructions of global mean sea level from earlier warm periods in Earth’s history can help constrain future projections of sea level rise. Here we report on the sedimentology and age of a geological unit in central Patagonia, Argentina, that we dated to the Early Pliocene (4.69–5.23...
Sea Level Rise Global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double that of the last century and is accelerating slightlyevery year. Image: Republic of Maldives: Vulnerable tosea level...
Greenhouse gasescontinue to build up in the atmosphere. Even if we start reducing the amount ofcarbon dioxide and other greenhouse gases, the climate is going to keep onwarming for decades or centuries. No one knows the effects of globa...
(Fig.1). However, the rate of global mean sea-level rise has also been increasing since 1993 based on an independent estimate from satellite altimeter data1,35, providing confidence in our results given that half of the global sea surface height increase is due to thermal expansion of the ...

Most estimates of global mean sea-level rise this century fall below 2 m. This quantity is comparable to the positive vertical bias of the principle digital elevation model (DEM) used to assess global and national population exposures to extreme coastal water levels, NASA’s SRTM. CoastalDEM ...
altimetry. The blue shading represents the range of model projections for the 21st century, relative to the 1980 to 1999 mean, and has been calculated independently from the observations. Beyond 2100, the projections are increasingly dependent on the emissions scenario.Impacts of Sea Level Rise ...
Concurrent heatwaves and extreme sea levels could pose a serious threat to coastal communities under climate change; however, the spatiotemporal characteristics and dynamic evolution of them along global coastline remain poorly understood. Here, we use reanalysis datasets and model projections to assess ...
