Scientists from Rice University and Texas A&M University - Corpus Christi's Harte Research Institute for Gulf of Mexico Studies have discovered that Earth's sea level did not rise steadily but rather in sharp, punctuated bursts when the planet's glaciers melted during the period of global warming at the close of the last ice age.

This is reassuring, because if the ice cap did melt completely in the near future, it would raise global sea levels by 60 metres.

Current projections of global sea level rise do not account for the complicated behavior of these giant ice slabs as they interact with the atmosphere, the ocean and the land.

Nonetheless, with rising sea level and environmental refugeeism compounding the increased demand on water, food, and land of a growing population (albeit one likely to level out mid 21st century), the combined impacts of climate change and global population increase could potentially yield a world that doesn't look that different from the one portrayed in the movie — indeed, as Jim Hansen puts it, «a different planet» — by century's end.

Third, using a «semi-empirical» statistical model calibrated to the relationship between temperature and global sea - level change over the last 2000 years, we find that, in alternative histories in which the 20th century did not exceed the average temperature over 500-1800 CE, global sea - level rise in the 20th century would (with > 95 % probability) have been less than 51 % of its observed value.

To do this, we linked the results from Rob and Dave's 2016 model to a framework for global and local sea - level rise projections that we published back in 2014.

If global warmning means rising sea level I just do not understand why the sea level hasn't changed the last 30 years when I have own my summer house.

One needs to apply enough smoothing (as in Fig. 3 above) to remove this noise, otherwise the computed rates of rise are dominated by sampling noise and have little to do with real changes in the rate of global sea - level rise.

For those of you who do not read Dutch: The Deltacommissie gives indeed 55 - 110 cm SLR for 2100 global, and the bit more for Holland (executive summary, p. 10, 2nd paragraph) is 0.65 - 1.30 m relative sea level rise (expected in Holland) by 2100, 2 - 4m by 2200.

First, there is room for disussion regarding whether a modest amount of global warming is bad, but I don't believe there can be much debate that a large amount of global warming would be horrible — there is no easy work - around for the relocation of a third of the world's major cities due to sea - level rise.

If global surface temp goes up 1 degree, does the sea level rise 3.4 mm per year for ever?

In a more recent paper, our own Stefan Rahmstorf used a simple regression model to suggest that sea level rise (SLR) could reach 0.5 to 1.4 meters above 1990 levels by 2100, but this did not consider individual processes like dynamic ice sheet changes, being only based on how global sea level has been linked to global warming over the past 120 years.

pg xiii This Policymakers Summary aims to bring out those elements of the main report which have the greatest relevance to policy formulation, in answering the following questions • What factors determine global climate 7 • What are the greenhouse gases, and how and why are they increasing 9 • Which gases are the most important 9 • How much do we expect the climate to change 9 • How much confidence do we have in our predictions 9 • Will the climate of the future be very different 9 • Have human activities already begun to change global climate 9 How much will sea level rise 9 • What will be the effects on ecosystems 9 • What should be done to reduce uncertainties, and how long will this take 9 This report is intended to respond to the practical needs of the policymaker.

In this regard, I would observe that at least one important AGW effect, rising sea level, does not depend on a specific regional outcome so much as on global mean T. (At least, I think this is so (because my understanding is that most of the rise comes from lower density of warmer water, not from melting ice sheets — though again, not 100 % sure on this point)-RRB-.

Heartland meeging did not see these person, even did not see the catestropic disaster in America, south clifornia drought wildfare, Denver mountine pine become yellow and bear no place to go, maypile tree can not made so much syrup, coastal land crupted, sea level rising let American herios graveyard sank into the water, many and many reality which global warming caused, all these I studied articles last 4 years about global warming.

Another, possibly best case scenario, shows that if global warming did not exceed the 2 degree Celsius benchmark, the millennial sea - level rise from the melting of Antarctic ice could likely be restricted to a few meters.

Vertical land movements such as resulting from glacial isostatic adjustment (GIA), tectonics, subsidence and sedimentation influence local sea level measurements but do not alter ocean water volume; nonetheless, they affect global mean sea level through their alteration of the shape and hence the volume of the ocean basins containing the water.

«The global mean sea level for the period January 1900 to December 2006 is estimated to rise at a rate of 1.56 ± 0.25 mm / yr which is reasonably consistent with earlier estimates, but we do not find significant acceleration»

This is because, from the discussion above, we would expect to see sea level changes, since global temperatures do seem to have changed over the last century (whether the temperature trends are man - made or natural in origin).

Nonetheless, the linear trends do offer us a crude method of seeing how global the apparent «global» sea level rise is.

So, they didn't actually simulate sea level changes, but instead estimated how much sea level rise they would expect from man - made global warming, and then used computer model predictions of temperature changes, to predict that sea levels will have risen by 0.8 - 2 metres by 2100.

Rising sea levels are a normal phenomenon linked to upthrust buoyancy; they are nothing to do with so - called global warming.

Since this doesn't seem to have occurred (despite some claims to the contrary — see Section 5), it suggests that the apparent sea level rise is a naturally - occurring phenomenon (perhaps due to natural global warming).

I must point out that this particular section generally holds info up to about 2010 ~ and so doesn't directly mention all the additional weight of scientific info in the last five years [i.e. all the newer «hot year» global records and even faster Ice Melt and sea - level rise].

Global mean temperatures in 2011 did not reach the record - setting levels of 2010, but were still the highest observed in a La Niña year, and Arctic sea - ice extent fell to near - record - low levels.

«We conclude that the 2 °C global warming «guardrail,» affirmed in the Copenhagen Accord, does not provide safety, as such warming would likely yield sea level rise of several metres along with numerous other severely disruptive consequences for human society and ecosystems,» Hansen and his colleagues wrote.

We can do that by internalizing the known costs of global warming and climate change and sea level rise that are not currently reflected in the price of the products that are causing them.

I do hope that the (much - hyped) issue of global sea - level rise and putative recent acceleration will be examined seriously here as a geophysical problem and not be subjected to summary number - crunching by inept blog lions who naively think that simple detrending of highly different tide - gauge records alleviates all issues of establishing a common datum - level.

If we do nothing to reduce our carbon emissions, scientists project that global sea level could rise as much as nearly two feet (59 centimeters) over recent average levels by the end of this century.14, 15 If, on the other hand, we make significant efforts to reduce heat - trapping emissions, sea - level rise between now and the end of the century could be limited to at most 1.25 feet (38 centimeters).14, 15

-- What does Global Sea Level rise mean?

Go ahead and show us on any of the following: Arctic Sea Ice Extent Antarctic Sea Ice Extent OHC Sea level Rise Rate Global Temperature Drought Incidence Hurricane Activity Tornado Activity Glacial Melting Like my mother use to tell me «Do something useful»

Yes, global warming events have occurred naturally in the past, and sea level rose as a consequence, but that doesn't tell us anything about the causes of the current global warming.

... incomplete and misleading because it 1) omits any mention of several of the most important aspects of the potential relationships between hurricanes and global warming, including rainfall, sea level, and storm surge; 2) leaves the impression that there is no significant connection between recent climate change caused by human activities and hurricane characteristics and impacts; and 3) does not take full account of the significance of recently identified trends and variations in tropical storms in causing impacts as compared to increasing societal vulnerability.

but the way I look at it... Gore's real estate investment is a clear sign that he doesn't buy into his own hype... i.e. that the sea level is rising at such a rapid rate due to man - made global warming the coast lines and life as we know it is going to be wiped out unless we immediately agree to Cap and Trade!!!

How, for example, does the fact that the sea level has been rising since 1961 (and in fact rising since 1861, although that's not mentioned) provide evidence either way for an anthropogenic cause for global warming?
