Melting sea ice would cause sea levels to rise by 'hair's breadth'

Melting icebergs are causing sea levels to rise, scientists have discovered, but only by a hair's breadth every year.

By Louise Gray, Environment Correspondent

Researchers at the University of Leeds calculate that around 1.5 million Titanic-sized icebergs each year are melting into the sea every year in the Arctic and Antarctic. This is causing sea level to rise by just 49 micrometers per year - around a hair's breadth.

At that rate it would take 200 years for the oceans to rise by 1cm as a result of melting sea ice. If all the floating ice in the world melted it would cause sea levels to rise by just 4cm. In comparison if all the ice on land melted it would cause a rise of 70m. Sea levels will also rise as the oceans get warmer because of thermal expansion.

But Professor Andrew Shepherd, one of the authors of the study published in Geophysical Research Letters, said the tiny rise caused by melting ice was still significant.

He said it will be important to factor in the small changes caused by melting sea ice in judging sea level rise in the future, especially if global warming accelerates. Melting ice caps also accelerate climate change as seawater absorbs more sunlight, therefore it will warm quicker than when the sea is covered in ice.

"Over recent decades there have been dramatic reductions in the quantity of Earth's floating ice, including collapses of Antarctic ice shelves and the retreat of Arctic sea ice," he said.

"These changes have had major impacts on regional climate and, because oceans are expected to warm considerably over the course of the 21st century, the melting of floating ice should be considered in future assessments of sea level rise."

Here we go again! If sea ice melts, the ocean levels will actually go down! But ya gotta give'em credit, they don't give up........

A simple experiment...

I like iced coffee, and after a couple of cups of hot coffee in the morning, I switch to iced. One thing I noticed was that as the ice melts, the level of coffee goes down. Ice is less dense when frozen. You can see that when water freezes and expands!

But then, I'm just a lowly drop-out. What do I know........

A lot of these comments seem to presume that it has been a prediction of global warming, that sea ice melts would cause sea levels to rise significantly. This isnt really the case.

There has been some thought that it would rise a little as sea ice melts, because fresh water ice apparently displaces less ocean water than its volume. But the contribution from this effect has never been predicted to be very large (a cm or two), at least not that I have ever seen.

Notice all the green on the outside of the thick white lines? That was unsubmerged land 18,000 years ago during the maximum extent of the ice age.

Those white lines are were the sea level is now with all that ice melted.

These jackasses assume that all the water that melts into the ocean stays there forever. :rolleyes: Such FUCKTARDS. They should learn a little bit about the water cycle.

The language is unfair. A crucial component of the water cycle is runoff from streams, into rivers and back into oceans. Truth be told, much of the precipitation caused by ocean moisture finds its way back into the ocean eventually.

Yet St Gore predicted 20 FOOT sea level rises.

Gore lied. Jones lied.The IPCC lied.

Thatisall.

I think the difference can be explained by "sea ice" vs "land based" ice.

Oh dear, you seem to have jumped to the hasty conclusion that since sea ice hasnt been predicted to be a major contributer to sea level rise, that the predictions of sea level rise are absurd or false. But all it really means is that sea ice melt wasnt predicted to be the cause. Most ice, however, is on land, and would contribute to drastic sea level rise, if melted.

Once again, another trivial error from Sonna that would embarass any person, even of dim intellect, but his obliviousness comes to the rescue!

And quite frankly, I have consulted the words of Al Gore exactly zero times while learning about global warming. So I don't give a shit what he says, right or wrong, crazy or sane.



Gore lied.

Maybe, but irrelevant.



Thatisall.

I hope so, for your sake.

The REALITY is that the sea may rise one CENTIMETRE.

The error is yours, I'll explain again, idiot. It might be Gores too, but who the hell cares?

It may rise one centimeter when only considering sea ice, stupid fool. Melting ice on land (glaciers, etc) has always been the worry, ignorant twat. Always.

All of the skeptics you quote and listen too and often quote, like Alan Watts, Rush Limbaugh, Ross McKitrick, Lord Monkton (basically the whole denialist cabal) have no official qualifications either, dipshit. You'd never ask for their credentials though, would you, sack of shit?

However, this doesn't matter - your errors are so profoundly basic and magnificently stupid, no climate science degree (nor a degree of any sort) is required to point them out - one simply needs a tiny amount of basic reading comprehension, at say, the level of the 5th grade or so.

You mistook the fact that sea ice isnt expected to contribute to sea level rise, to mean that no ice is expected to contribute to sea level rise. Its not my unqualified opinion that you are wrong here- its incontrovertible fact. Take a moment to let it sink in, just how stupid you are... seriously, think on it, if you can. Its amazing.

I dont need to..all I need do is look at the massively mounting pile of evidence, lies, mistruths, omissions and out and out fabrications.

As for why they do it, well let's just say that Michael Mann, a major panic monger and author of the now fully discredited hockey stick, just got a 1.8 million dollar grant to study what exactly?? With his co researcher Matthew Thomas (http://www.examiner.com/x-9111-Environmental-Policy-Examiner%7Ey2010m5d21-Global-warming-Michael-Mann-finds-a-new-research-plaything?cid=exrss-Environmental-Policy-Examiner)


"If we were to go back to the 1900s with the correct climate change predictions for the 20th century, modellers would predict expansion and worsening of malaria and they would have been wrong, and we believe they are wrong now." That's because despite global warming for the past 30 years, the geographic extent of malaria has lessened, leading logical thinkers to guess that climate change has not worsened the spread of malaria.So they get over a million dollars to research something we already know, that malaria is not worsening and there is no link to so called "climate change"


However, this doesn't matter - your errors are so profoundly basic and magnificently stupid, no climate science degree (nor a degree of any sort) is required to point them out - one simply needs a tiny amount of basic reading comprehension, at say, the level of the 5th grade or so. You mean likes reading Jone's lies? The fabrications? Deliberate destruction of data? Deliberate avoidance of FoI requiests and then destroying data rather than have it checked?

You mean like the "models" that are based on data no longer available and can only be checked by using a time machine?



You mistook the fact that sea ice isnt expected to contribute to sea level rise, to mean that no ice is expected to contribute to sea level rise. Its not my unqualified opinion that you are wrong here- its incontrovertible fact. Take a moment to let it sink in, just how stupid you are... seriously, think on it, if you can. Its amazing.I simply state that Gore, who started this panic mongering, claimed there would be 20 foot sea rises.

He lied.

# The claim: Melting in Greenland or West Antarctica will cause sea levels to rise up to 20 feet in the near future. The truth: The Intergovernmental Panel On Climate Change concluded that sea levels might rise 20 feet over millennia -- and it waffled on that prediction. The IPCC envisions a rise of no more than 7 inches to 23 inches by 2100 [which follows the natural trend and is right where it should be]. Gore's claim is "a very disturbing misstatement of the science," John Day, who argued the British case, says in Not Evil Just Wrong. The judge said Gore's point "is not in line with the scientific consensus.

# The claim: Polar bears are drowning because they have to swim farther to find ice. The truth: Justice Burton noted that the only study citing the drowning of polar bears (four of them) blamed the deaths on a storm, not ice that is melting due to manmade global warming. The Senate Environment and Public Works Committee, furthermore, found that the current bear population is 20,000-25,000, up from 5,000-10,000 in the 1950s and 1960s. Day says in Not Evil Just Wrong that the appeal to polar bears is "a very clever piece of manipulation."

# The claim: Global warming spawned Hurricane Katrina in 2005. The truth: "It is common ground that there is insufficient evidence to show that," Burton wrote in his ruling. A May 2007 piece in New Scientist refuted the Katrina argument as a "climate myth" because it's impossible to tie any single weather event to global warming.

# The claim: Increases in temperature are the result of increases in carbon dioxide. The truth: Burton questioned the two graphs Gore used in An Inconvenient Truth. Gore argued that there is "an exact fit" between temperature and CO2, Burton said, but his graphs didn't support that conclusion. Recent data also do not support it: The global temperature has been declining for about a decade, even as CO2 levels continue rising.

# The claim: The snow on Mount Kilimanjaro is melting because of global warming. The truth: The melting has been under way for more than a century -- long before SUVs and jumbo jets -- and appears to be the result of other causes. Justice Burton noted that scientists agree the melting can't be blamed primarily on "human-induced climate change."

# The claim: Lake Chad is disappearing because of global warming. The truth: Lake Chad is losing water, and humans are contributing to the losses. But the humans in the lake's immediate vicinity, rather than mankind as a whole using fossil fuels, are to blame. Burton cited factors like population, overgrazing and regional climate variability.

# The claim: People are being forced to evacuate low-lying Pacific atolls, islands of coral that surround lagoons, because of encroaching ocean waters. The truth: By their very nature, atolls are susceptible to rising sea levels. But Burton said pointedly in his ruling, "There is no evidence of any such evacuation having yet happened."

# The claim: Coral reefs are bleaching and putting fish in jeopardy. The truth: In his ruling, Burton emphasized the IPCC's finding that bleaching could kill coral reefs -- if they don't adapt. A report released this year shows that reefs already are thriving in waters as hot as some people say ocean waters will be 100 years from now. Burton also said it is difficult to separate coral stresses such as over-fishing from any changes in climate.

# The claim: Global warming could stop the "ocean conveyor," triggering another ice age in Western Europe. The truth: Once again, Gore's allies at the IPCC disagree with that argument. Burton cited the panel in concluding that "it is very unlikely that the ocean conveyor ... will shut down in the future." The fact that the scientific understanding of how the conveyor belt works remains unsettled further exposes the flaw in Gore's claim

Oh and wilbur, I hate to burst your bubble, but even though I can get Limbaugh here, I dont listen.

Had it ever occurred to you that maybe I made up MY OWN MIND, after reading a large number of different sources? You keep coming back to this liberal meme that others tell me what to think...had it ever occurred to you that perhaps I have a mind of my own and I made the decision as to what to believe, and what not to?

What does Limbaugh have to do with this anyway?

Nothing. :rolleyes:
