There are some painful, and even dire, concerns expressed about the potential that Greenland ice sheets could be «entirely lost» if emissions continue at a business - as - usual pace; about the rate of sea - level rise increasing «faster and faster with time»; and about the planet's ice sheets likely becoming «more active» over coming decades than they have been over recent decades.

From recent instrumental observations alone we are therefore unable to predict whether mass loss from these ice sheets will vary linearly with changes in the rate of sea - level rise, or if a non-linear response is more likely.

One problem is that if the ocean has lost heat at the suggested rate, then the thermal exapansion part of recent sea level rise should have decreased (i.e. sea level should have dropped).

Curry also argues that the rate of sea level rise during 1930 — 1950 was similar to that in recent years, according to the IPCC, which suggests that ocean heat content was increasing at a similar rate to today.

Recent evidence of faster rates of global sea - level rise suggests that these projections may be too low.3, 4,5 Given recent accelerated shrinking of glaciers and ice sheets, scientists now think that a rise of 2.6 feet (80 centimeters) is plausible — and that as much as 6.6 feet (2 meters) is possible though less likRecent evidence of faster rates of global sea - level rise suggests that these projections may be too low.3, 4,5 Given recent accelerated shrinking of glaciers and ice sheets, scientists now think that a rise of 2.6 feet (80 centimeters) is plausible — and that as much as 6.6 feet (2 meters) is possible though less likrecent accelerated shrinking of glaciers and ice sheets, scientists now think that a rise of 2.6 feet (80 centimeters) is plausible — and that as much as 6.6 feet (2 meters) is possible though less likely.16

Sea level rise is tied to warming and non-anthropogenic factors can influence the rate of warming, even if anthropogenic factors are the dominant cause of recent warming.

Three recent journal articles examine the rate of sea level rise and the ability of models to accurately simulate sea level rise at a global and regional scale.

For reference, the recent rate of global sea level rise is 3 mm / yr.

With the recent decline in solar flux and the shift to cool phases of ocean oscillations, natural climate change suggests that although glacier retreat and sea level rise will likely continue over the next few decades, the rates of sea level rise and glacier retreats will slow down.The next decade will provide the natural experiment to test the validity of competing hypotheses.

The average rate of sea - level rise in the 20th century was 15 cm / century, but in the quarter - century since 1990 it has been 30 cm / century and is showing signs of further acceleration in more recent measurements.

The extra heat in the ocean has caused the sea level to rise 15 mm since November 2014, much faster than the rate of 3 - 3.5 mm per year over recent decades.

The loud divergence between sea - level reality and climate change theory — the climate models predict an accelerated sea - level rise driven by the anthropogenic CO2 emission — has been also evidenced in other works such as Boretti (2012a, b), Boretti and Watson (2012), Douglas (1992), Douglas and Peltier (2002), Fasullo et al. (2016), Jevrejeva et al. (2006), Holgate (2007), Houston and Dean (2011), Mörner 2010a, b, 2016), Mörner and Parker (2013), Scafetta (2014), Wenzel and Schröter (2010) and Wunsch et al. (2007) reporting on the recent lack of any detectable acceleration in the rate of sea - level rise.

You are aware the sea level rise has not altered for decades (rate of change) and whilst it is a positive trend it remains fairly constant and has in fact slowed in recent years?

This coincides with post-1970s global warming, as expected, given point 1: «New estimate of the current rate of sea level rise from a sea level budget approach» «Recent global sea level acceleration started over 200 years ago?»

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.

Mass gains of the Antarctic ice sheet exceed losses Mass changes of the Antarctic ice sheet impact sea - level rise as climate changes, but recent rates have been uncertain.

Mass changes of the Antarctic ice sheet impact sea - level rise as climate changes, but recent rates have been uncertain.

«Second, in contrast to the previously reported slowing in the rate during the past two decades1, our corrected GMSL data set indicates an acceleration in sea - level rise (independent of the VLM used), which is of opposite sign to previous estimates and comparable to the accelerated loss of ice from Greenland and to recent projections, and larger than the twentieth - century acceleration.

The authors further note that «Estimates of recent rates of global sea level rise (GSLR) vary considerably» noting that many scientists have calculated rates of 1.5 to 2.0 mm per year over the 20th century.

Kolker and Hameed begin their article stating «Determining the rate of global sea level rise (GSLR) during the past century is critical to understanding recent changes to the global climate system.

The G refers to global, thus the MEAN global T must rise, the mean sea ice extent must decrease, global sea level trend must increase, global tornadoes must rise, global floods must increase, the rate of global sea riseust rise, and all the global change MUST be catastrophic, and clearly outside of recent past global flux.

Records for a more recent, 40 - year period, beginning in 1970, revealed faster rates of sea - level rise both globally and for this stretch of the U.S. East Coast.

The rate of sea - level rise has continued to increase in recent decades:

Recent research has shown that the major ice sheets (those of Greenland and Antarctica, which contain 23 feet and 197 feet of sea - level rise, respectively) are shrinking at a faster rate than they were a decade ago.

Per a recent paper by Fasullo et al, «In stark contrast to this expectation however, current altimeter products show the rate of sea level rise to have decreased from the first to second decades of the altimeter era.»

During the 1958 to 2014 period, when CO2 emissions rose dramatically, a recent analysis revealed that the rate of sea level rise slowed to between 1.3 mm / yr to 1.5 mm / yr, or just 0.14 of a meter per century.

Hansen and Sato (7) argue that the climate of the most recent few decades is probably warmer than prior Holocene levels, based on the fact that the major ice sheets in both hemispheres are presently losing mass rapidly (9) and global sea level is rising at a rate of more than 3 m / millennium (25), which is much greater than the slow rate of sea level change (less than 1 m / millennium) in the latter half of the Holocene (26).

If the rate of sea level rise over the last 20 years is as high or higher than it ever has been over the last 114 year (and is twice the 20th century average), then does this not strongly suggest that there has been no recent slowdown at all in the rate of accumulation of heat by the oceans and cryosphere?

However, recent observations of the rate and severity of physical and ecological responses to escalating radiative forcing — melting glaciers and ice sheets resulting in sea level rise and major changes in weather patterns, prolonged droughts, more frequent hurricanes and storms, and so on — are surprising even top climate experts, and raising awareness that, as a nation, we are dangerously unprepared for the inevitable consequences.
