Recent global sea level acceleration started over 200 years ago?
[1] We present a reconstruction of global sea level (GSL) since 1700 calculated from tide gauge records and analyse the evolution of global sea level acceleration during the past 300 years. We provide observational evidence that sea level acceleration up to the present has been about 0.01 mm/yr and appears to have started at the end of the 18th century. Sea level rose by 6 cm during the 19th ce...
متن کاملA sustained þ21 m sea-level highstand during MIS 11 (400 ka): Direct fossil and sedimentary evidence from Bermuda
A small, protected karstic feature exposed in a limestone quarry in Bermuda preserved abundant sedimentary and biogenic materials documenting a transgressive phase, still-stand, and regressive phase of a sea-level in excess of 21.3 m above present during Marine Isotope Stage (MIS) 11 (400 ka) as determined by U/Th dating and amino acid racemization. Cobbles and marine sediments deposited during...
متن کاملPresent - to - future sea level changes : The Australian case
We revisit available tide gauge data along the coasts of Australia, and we are able to demonstrate that the rate may vary between 0.1 and 1.5 mm/ year, and that there is an absence of acceleration over the last decades. With a database of 16 stations covering only the last 17 years, the National Tidal Centre claims that sea level is rising at a rate of 5.4 mm/year. We here analyse partly longer...
متن کاملRapid rise of sea level 19,000 years ago and its global implications.
Evidence from the Irish Sea basin supports the existence of an abrupt rise in sea level (meltwater pulse) at 19,000 years before the present (B.P.). Climate records indicate a large reduction in the strength of North Atlantic Deep Water formation and attendant cooling of the North Atlantic at this time, indicating a source of the meltwater pulse from one or more Northern Hemisphere ice sheets. ...
متن کاملEstimates of Future Sea Level Rise
Accurate monitoring of atmospheric carbon dioxide began 25 years ago. Since then, sufficient scientific evidence has been developed for two National Academy of Sciences review panels to conclude that sometime in the next century, atmospheric concentrations of C02 will almost certainly double and raise the atmosphere's mean surface temperature by at least 1.5C (2.7 F) and possibly as much as 4.5...
