Global sea level rise is caused by two factors. One is the delivery of water to the ocean as land ice melts, such as mountain glaciers and polar icecaps. Current evidence of global warming includes the widespread retreat of glaciers on 5 continents. For example: chanton2photo.jpg

* The ice cap on Mount Kilimanjaro may be gone in 20 years. About 1/3 of Kilimanjaro’s ice field has disappeared in the last 12 years and 82% of it has vanished since it was first mapped in 1912. * Sea ice in the Arctic Ocean is thinning. * Massive Antarctic ice sheets have collapsed into the sea with alarming rapidity.
As water temperatures rise, oceans spread. The 20th century has seen a dramatic rise in sea levels.
The second factor is the thermal expansion of water within the oceans. As the temperature of the waters in the oceans rises and the seas become less dense, they will spread, occupying more surface area on the planet. Increased temperature will accelerate the rate of sea level rise.
Since the end of the last ice age, 18,000 years ago, sea level has risen by over 120 meters.
* Geological data suggests that global average sea level may have risen at an average rate of 0.1 to 0.2 mm/yr over the last 3000 years. * However, tide gauge data indicate that the global rate of sea level rise during the 20th century was 1 to 2 mm/yr.
Along relatively flat coastlines, such as those of the Atlantic, or coastlines bordering fertile, highly populated river deltas, a 1 mm rise in sea level causes a shoreline retreat of about 1.5 meters. We are already seeing evidence of shoreline retreat in the U.S.: Coastal U.S. has seen beach erosion and dying coastal plants.
* Along the marshy Gulf Coast of Florida, the effects of sea level rise can be observed in the number of dead cabbage palms at the seaward edge of the salt marsh. * Along the Atlantic Coast of the USA, erosion is narrowing beaches and washing out vacation houses. As sea level rises and coastal communities continue to grow and pump water from aquifers, salt water intrusion into groundwater will become a greater problem.
Low-lying Pacific island nations will be inundated or the rising sea level will invade their drinking water aquifers. Land of some island nations is being submerged under water.
* Tuvalu comprises nine coral atolls between Australia and Hawaii. Their highest point is 5 meters (15 feet) above seal level. As sea level has risen, Tuvalu has experienced lowland flooding. Saltwater intrusion is adversely affecting drinking water and food production. Tuvalu’s leaders predict that the nation will be submerged in 50 years. In March 2002, the country’s prime minister appealed to Australia and New Zealand to provide homes for his people if his country is washed away, but the plight of this nation is being ignored. * Other threatened island nations include the Cook Islands and the Marshall Islands. During the last decade, the island of Majuro (Marshall Islands) has lost up to 20 per cent of its beachfront.
The near future could see millions of “climate refugees.”
In addition to island nations, low-lying coastal countries are threatened by rising sea level. A 1 meter rise in sea level would inundate half of Bangladesh’s rice land. Bangladeshis would be forced to migrate by the millions. Other rice growing lowlands which would be flooded include those of Viet Nam, China, India and Thailand. Millions of climate refugees could be created by sea level rise in the Philippines, Indonesia and Egypt.
Or you can just belive everything you are told. Like "global warming is real. That ones right up with the Easter Bunny. Try it at home if you would like. Did you know that glaciers are growing in all the other areas? It helps to use the whole world when you are forming a theory. If you only use the North or South poles then you only have half the story.
Do you remember all the op eds about the acid rain? The ice age that should be here by now? And you still believe in the Easter Bunny? You must be living in bliss.
ExxonMobil cash supported concerted campaign to undermine case for man-made warming
By Jonathan Owen and Paul Bignell
An orchestrated campaign is being waged against climate change science to undermine public acceptance of man-made global warming, environment experts claimed last night.
The attack against scientists supportive of the idea of man-made climate change has grown in ferocity since the leak of thousands of documents on the subject from the University of East Anglia (UEA) on the eve of the Copenhagen climate summit last December.
Free-market, anti-climate change think-tanks such as the Atlas Economic Research Foundation in the US and the International Policy Network in the UK have received grants totalling hundreds of thousands of pounds from the multinational energy company ExxonMobil. Both organisations have funded international seminars pulling together climate change deniers from across the globe.
We Have Had a Ice Age Years Ago and The Ice Melted! Global Warming/Climate Change Alarmist Say We are Contributing to Global Warming! Years Ago WE Were Not Here! Wonder What Caused the Ice to Melt! My Guess is Mother Nature Who to This POINT seems to be More Honest than The Scientist Tolling the Alarm Bell! There MOTTO Seems to be "If it DOES Not FIT You MUST Delete! I Also Am STILL Waiting For the NEXT Ice Age Predicted in Late 1970s and Howd That Work OUT!
Bruce I gotta Believe there are SOME Very Rich People in the World WHO Have Invested Millions if NOT More In the Climate Change Theory and For it to BE Proven a SHAM would NOT Make them Happy!
Bruce I'm not talking about droping glaciers into the oceans. I'm talking about glarciers melting. Do you understand the difference? Do you know which is more dense ice or water? And you are believing data and an op ed. Once I heard that much of the data is wrong and that this global warming in based on shody data at best. And Bruce if you are talking about mountain tops melting at the same rate as glaciers at sea level then climb a mountian and tell me what you see in the middle of summer. killamanjero ring a bell? 1 degree isn't going to melt those things. And while the North pole shrinks the South pole is growing. The data you are using is chosen for an outcome. Get your head out of the sand and see the hoax you bought into. BWAAAAHAHAHAHHAAHAHHAA
Bruce it's the scientist that have undermind global warming not a group. You are way too much of a tinfoil head Bruce. You believe a conspiracy before you believe the words and actions of the people that made this money making hoax called global warming. I understand it's more like a religion to you. Just like most liberals they would rather believe the obsurd before the logical(occem's razor). They would rather believe aliens seeded the earth before they would belive in God. They would rather believe in spontanious life without any proof rather then intelligent design. If you need to know what Occem's Razor is I have an old post on it. Just go on the search.
Leave it to fealk to bring on a link from 2002 to advance his ocean rising scenarios. At least he could bring current junk to the table.
Sea ice could not even be accurately measured until the use of satellites in 1979. And current data proves that the ocean ice is expanding, not retreating.
I don't have time to go through point by point, but brucie is shameless in his shoddy research before posting BS as fact. Here is a Kilimanjaro rebuttal. http://icecap.us/images/uploads/Sampling_of_Scientific_Reality_Checks_on_Mount_Kilimanjaro.pdf
The ruse is over. bruce should take that paper mache head out of his ass and join reality for a change.
Chris, i don't know why the old MD soundoff growd continues to act like Acid Rain was a myth. It was and still to some extent a threat for the Northestern area of America and southern Canada.
Chris, The reality that certain areas the acid content of rain is effected by natural sources and others it has a high man made effect to it.
When we discuss acidic precipation that occurs naturally we are looking at either that which has a high sulfur content from volcanic activity or that which has a high carbonic acid content.
Man made acid rain exists and is a factual reality. The levels of pollutants like oxides from sulfur and nitrogen in cloud cover and precipation in areas of low natural sources for such things. The areas down prevailing wind from the heaviest manufacturing areas have high levels of nitric acid in their precipation and even dry acid droppout.
Look at La which has a super low Ph of 2. being recorded in its fog and little natural volcanic activity to account for its high sulfuric oxides. the only viable condition is pollution whihc is evident by the haze and smog surrounding the city.
Its one thing to deny that man has made all of the problems but another to deny that man hasn't effected a situation detrimentally.
If all the ice capes melted from "global warming" will it really make the oceans rise? Does your glass overflow when the ice melts?
Chris, do you always have to show your lack of intellect?

ReplyDeleteChris, a glass of water is different than massive ice sheets melting. Did you read the article I posted? The oceans are already rising.
ReplyDeleteIf you have a glass of water and you start dropping ice cubes in it, does it overflow?
