«The shock for us was that tidal flooding could become the new normal in the next 15 years; we didn't think it would be so soon,» said Melanie Fitzpatrick, one of three researchers at the nonprofit who analyzed tide gauge
data and
sea level projections,
producing soused prognoses for scores of coastal Americans.
The filter can
produce smooth
sea -
level curves which are as long as the original unsmoothed curves so it does not end before the original
data, and you can see the rate curves go as far as the
sea level curves in Fig. 1.
[Response: Hi Neil, I noticed the same thing and wondered whether a «flat bit» can indeed shift the whole curve thereafter — this would be the case if the method reconstructs
sea -
level increments from the
data and then
produces the proper
sea -
level curve by time integration.
The GRACE observations over Antarctica suggest a near - zero change due to combined ice and solid earth mass redistribution; the magnitude of our GIA correction is substantially smaller than previous models have suggested and hence we
produce a systematically lower estimate of ice mass change from GRACE
data: we estimate that Antarctica has lost 69 ± 18 Gigatonnes per year (Gt / yr) into the oceans over 2002 - 2010 — equivalent to +0.19 mm / yr globally - averaged
sea level change, or about 6 % of the
sea -
level change during that period.
An international team of experts supported by NASA and the European Space Agency (ESA) has combined
data from multiple satellites and aircraft to
produce the most comprehensive and accurate assessment to date of ice sheet losses in Greenland and Antarctica and their contributions to
sea level rise.
Aside from CU there are at least five other groups analysing and
producing sea level datasets from satellite altimeter
data.
The tide gauges combined with co-located GPS receivers are more accurate (real
data) and
produces a value around 1.3 to 1.8 mms / year of
sea level rise over about 150 sites across the world.
The
sea level data set used here is based on the
sea level Ocean Monitoring Indicators
produced by CMEMS and for which the C3S products (C3S - v0 / DUACS DT - 2014) are used as input
data.
The long - term eruption
data, spread over more than 700,000 years, showed that during the coldest times, when
sea levels are low, undersea volcanism surges,
producing visible bands of hills.
-- These two distinct satellite systems, using very different measurement methods,
produced raw
data reaching identical conclusions:
sea level is barely rising, if at all.
Instead, for every adjustment of raw
data analyzed, «the adjustments are always in the direction to
produce a large rise in
sea level.»
The fundamental
data sets
produced by the icePod system are necessary to support the development of accurate ice sheet models to predict
sea level rise.
