Abstract. A time series of mean-sea-level pressure was built from observations performed in Trieste 1 January 1841 to 31 December 2018. Original historical documents provided information on the instruments and observation sites. Mercury barometers have always been available. Until 1877 they represented only operation, while 1878 onwards barograph records became The consists mean daily values th...

Abstract Barystatic sea level rise (SLR) caused by the addition of freshwater to ocean from melting ice can in principle be recorded a reduction seawater salinity, but detection this signal has been hindered sparse data coverage and small trends compared natural variability. Here, we develop an autoregressive machine learning method estimate salinity changes global 2001 2019 that reduces uncert...

different ecologic factors influence on forming, development and sustaining of the plant communities, among which physiographic variables are the most important ones. the aim of this study was to identify forest types and effect of physiographical factors such as sea level height, slope and aspect of the site on quantitative characteristics of forest types in 2nd district of vaz forest with are...

Rahmstorf (Reports, 19 January 2007, p. 368) presented an approach for predicting sea-level rise based on a proposed linear relationship between global mean surface temperature and the rate of global mean sea-level change. We find no such linear relationship. Although we agree that there is considerable uncertainty in the prediction of future sea-level rise, this approach does not meaningfully ...

Global mean sea levels are projected to gradually rise in response to greenhouse warming. However, on shorter time scales, modes of natural climate variability in the Pacific, such as the El Niño-Southern Oscillation (ENSO), can affect regional sea level variability and extremes, with considerable impacts on coastal ecosystems and island nations. How these shorter-term sea level fluctuations wi...

Ocean dynamics, land motion, and changes in Earth’s gravitational and rotational fields cause local sea level change to deviate from the rate of global mean sea level rise. Here we use observations and simulations of spatial structure in sea level change to estimate the likelihood that these processes cause sea level trends in the longest and highest-quality tide gauge records to be systematica...
