In addition, there are no guarantees that the current rate will be maintained, since many studies have shown the likelihood of a
higher rate of sea level rise as global warming continues.
Human contribution so far to sea level rise does not seem particularly significant, given the early 20th
century rate of sea level rise is about the same as the current rate.
That makes me wonder, is there a
critical rate of sea level rise above which the reefs can't collect sediment quickly enough to keep up?
This process is difficult to accurately model, but rapid ice sheet collapse would certainly result in dramatically
higher rates of sea level rise once this critical threshold is passed.
«Having a detailed picture of
rates of sea level change over the past two millennia provides an important context for understanding current and potential future changes,» says Paul Cutler, program director in NSF's Division of Earth Sciences.
Substantial spatial variation
in rates of sea level change is also inferred from hydrographic observations.
Summary Short records of sea level measurements by the Ordnance Survey at 31 locations in 1859 — 1860, together with recent Mean Sea Level (MSL) information from the UK tide gauge network, have been used to estimate the
average rates of sea level change around the coast of Great Britain since the mid-19th century.
Finally NOAA 2016 updated coastal sea level rise tide gauge data shows no acceleration in sea level rise along the California coastline or anywhere else despite false claims by the UN IPCC that man made emissions have been
increasing rates of sea level rise since the 1970's.
He and his colleagues harnessed 25 years of satellite data to calculate that the rate is increasing by about 0.08 mm / year every year — which could mean an
annual rate of sea level rise of 10 mm / year, or even more, by 2100.
Paleoclimate data are not as helpful for defining the
likely rate of sea level rise in coming decades, because there is no known case of growth of a positive (warming) climate forcing as rapid as the anthropogenic change.
Geologist Torbjörn Törnqvist of Tulane University, a co-author of the study, said that given
accelerating rates of sea level rise, losses will likely continue long into the future, and that even the best - designed river diversions won't be able to prevent more land loss.
The US East Coast and Gulf of Mexico experienced some of the world's
fastest rates of sea level rise in the twentieth century due to local and regional factors.
Combining Zwally's calculations with recent evidence from Greenland, sea level models driven by global warming should reveal a
decreasing rate of sea level rise.
«Our work will certainly sound the alarm about the possible effects of climate change on shifting patterns of freshwater availability, as well as the potential for modulating
future rates of sea level rise by managing the amount of freshwater stored on land.»
This extremely abrupt flood may have involved
peak rates of sea level rise in the Mediterranean of more than ten metres per day.
A certain scientist has often stated that the rate of SLR in the first half of the 20th century often was about the same
as rate of sea level rise seen today.
«It's a powerful conclusion that these two different scenarios
give rates of sea level rise that aren't that different from one another,» Cloern said.
A new paper by Levermann et al. in PNAS uses the record of
past rates of sea level rise from palaeo archives and numerical computer models to understand how much sea level rise we can expect per degree of warming in the future.
«The point is that whatever happens in this century can only start from present conditions and
present rates of sea level rise, and that constrains the rise that can occur this century,» he told BBC News.
If you look at this from the point of view of somebody who's trying to use this information for anything other than scientific satisfaction, whether or not these very, very
rapid rates of sea level rise happen in the next few decades or the next few centuries makes all the difference in the world.
The ENVISAT instrument which suddenly «failed» last year (well short of its design life) indicated a much
lower rate of sea level rise.
The «
possible rate of sea level rise» referred to has been substantially reduced by the IPCC from their previous estimates, and the range between upper and lower estimates narrowed.
According to the study published in the journal Nature, the eruption, which is considered the largest eruption in the late 20th century, hid clues of climate change by briefly cooling the oceans; thus, the
steady rate of sea level rise since 1993.
