Sea level rise due to AGW

For scientific papers on AGW, record happenings in the Arctic and the Greenland, Himalayan and Antarctic icesheets. Also weatherstorms and higher than average rainfalls and other extreme weather events.

Sea level rise due to AGW

Postby HBS Guy » 12 Sep 2017, 15:06

AGW causes sea levels to rise in two ways:

1. The melting of landbased icesheets and glaciers, calving of glaciers at sea level

2. Thermal expansion of the seas as water temperatures rise.

Have a look what sea level rise will increasingly mean:

The village being flooded was obviously an affluent one with large stone and cement houses.

Global sea level rise has been accelerating in recent decades, rather than increasing steadily, according to a new study based on 25 years of NASA and European satellite data.

This acceleration, driven mainly by increased melting in Greenland and Antarctica, has the potential to double the total sea level rise projected by 2100 when compared to projections that assume a constant rate of sea level rise, according to lead author Steve Nerem. Nerem is a professor of Aerospace Engineering Sciences at the University of Colorado Boulder, a fellow at Colorado's Cooperative Institute for Research in Environmental Sciences (CIRES), and a member of NASA's Sea Level Change team.

If the rate of ocean rise continues to change at this pace, sea level will rise 26 inches (65 centimeters) by 2100 -- enough to cause significant problems for coastal cities, according to the new assessment by Nerem and colleagues from NASA's Goddard Space Flight Center in Greenbelt, Maryland; CU Boulder; the University of South Florida in Tampa; and Old Dominion University in Norfolk, Virginia. The team, driven to understand and better predict Earth’s response to a warming world, published their work Feb. 12 in the journal Proceedings of the National Academy of Sciences.

"This is almost certainly a conservative estimate," Nerem said. "Our extrapolation assumes that sea level continues to change in the future as it has over the last 25 years. Given the large changes we are seeing in the ice sheets today, that's not likely."

Prof Eric Rignot did warn that “non linearities” could upset calculations of sea level rise. Acceleration is non–linear: it is exponential, the integral of ∆v/∆t, like compound interest and we will be paying that interest if we don’t get more serious about reducing emissions and removing CO2 from the atmosphere.

Yes HBSG.... or can I just call you Monk, please.?
Um I haven't checked your link. I will.

This rise in sea levels WILL happen, and it is a shame that politics, particularly here in Australia, find it hard to grasp this fact.

I became aware of this possibility/certainty over 30 years ago, when the first people started talking about the future for THE planet, and our impacts upon it. Virtually nothing has been done.
OK we banned HFC's and some other ozone-depleting gases, which HAS had a positive impact on the Antarctic Hole... but this is stuff all. !

IT does prove we CAN have a + impact, and it also shows, despite all contrary argument.. that we have had -negative impact. To say different is arrogance and ignorance of the highest order.


Ummm.. I chose my property based on several factors.. I have a creek at my foot, BUT it will never flood my home. I'm on the high side of the meander that enters and exits my lower western boundary.
I may get stranded due to flooding downstream, but hey I'll manage.
I am on high ground. It is roughly 25 mtr above sea level. Amazing to think that my home could one day be on an Island.!
sleep is bliss: do it as often and for as long as you need.
