While researching climate change, we heard something confusing: the sea level in New York City is rising about one and a half times faster than the global average. We couldn’t figure out what that meant. Isn’t the sea level...flat? So we called up an expert and went down the rabbit hole. And, we did our best to visualize her truly bizarre answers with animations, dioramas, and a lot of melting ice.

Calcutta, Shanghai, London - low lying cities will get into trouble if sea levels continue to rise. Ice masses at the poles melting due to global warming are a major reason. But not all ice on the planet is the same. Global Ideas Climate Expert Anders Levermann (http://www.pik-potsdam.de/~anders/) explains which of the ice masses are relevant and how much sea levels would rise if all ice at or near the poles melted.

We learned last year that many of the effects of climate change are irreversible. Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century. As National Geographic showed us in 2013, sea levels would rise by 216 feet if all the land ice on the planet were to melt. This would dramatically reshape the continents and drown many of the world's major cities.

#COP21 @UNDP undo.org/cop21 Boobu Tioram, a resident of the Pacific island of Kirabati, took time out from reinforcing a seawall in front of his newly built house to speak with UNDP about what climate change has meant to his way of life. I have moved three times, every three years I have moved, he said, standing on the beach a few metres from his home. Tioram gestured toward a point about 20 metres into the sea, and explained that his first house once stood on a spot now covered in swelling ocean waves. Each time he has moved farther inland, and each time the sea has followed. Im not sure how long Ill be [in this house], Tioram continued. That depends on how strong my seawall here can withstand high tide waves. UNDP believes that it is the developing world that stands to lose the most, and which is already losing out, as the effects of climate change edge toward the catastrophic. As climate negotiations open in Copenhagen, worlds away from this tiny Pacific nation consisting of 33 low lying atolls, it is important to keep in mind that for the people of Kirabati, and other poor island and coastal nations, funds for adaptation and not only prevention must top the international to-do list. Carbon trading will be of no special consequence to us, so there has got to be some very special provisions for the victims, said Kirabati President Anote Tong. Not the potential victims, but the victims, because we are the victims, so there has to be some very deep soul searching. Kirabati is no more than four metres high at its highest point, and 100 percent of the population lives within one kilometre of the coast, making this nation one of the most vulnerable to the effects of global warming. Its future is uncertain, including the question of whether it even has a future anymore. The scientific research shows that by 2100 its almost certain that well have more than a metre of sea level rise, said Karen Bernard, a UNDP programme specialist in natural disaster reduction and transition. On a flat island like Kirabati that mount of sea level rise comes very far inland. Its a very serious situation, Bernard continued. For that reason, the Government is looking for options for relocating the population.

Climate change and rising sea levels mean the island nation of Kiribati in the South Pacific is at risk of disappearing into the sea. But the island’s inhabitants aren’t giving up. They are doing what they can to save their island from inundation. Can COP23 help make a difference? UN estimates indicate that Kiribati could disappear in just 30 or 40 years. That’s because the average elevation is less than two meters above sea level. And some of the knock-on effects of climate change have made the situation more difficult. Kiribati can hardly be surpassed in terms of charm and natural beauty. There are 33 atolls and one reef island – spread out over an area of 3.5 million square kilometers. All have white, sandy beaches and blue lagoons. Kiribati is the world’s largest state that consists exclusively of atolls. A local resident named Kaboua points to the empty, barren land around him and says, "There used to be a large village here with 70 families." But these days, this land is only accessible at low tide. At high tide, it's all under water. Kaboua says that sea levels are rising all the time, and swallowing up the land. That’s why many people here build walls made of stone and driftwood, or sand or rubbish. But these barriers won't stand up to the increasing number of storm surges. Others are trying to protect against coastal erosion by planting mangrove shrubs or small trees. But another local resident, Vasiti Tebamare, remains optimistic. She works for KiriCAN, an environmental organization. Vasiti says: "The industrialized countries -- the United States, China, and Europe -- use fossil fuels for their own ends. But what about us?" Kiribati's government has even bought land on an island in Fiji, so it can evacuate its people in an emergency. But Vasiti and most of the other residents don't want to leave. _______ Exciting, powerful and informative – DW Documentary is always close to current affairs and international events.

Global sea levels rose about 2 mm per year over the last century, but this rate increased to 3.4 mm/yr over the last decade. As Greenland and Antarctic ice cap melt rates accelerate, they open up the likely scenario of a global sea level rise of 7 meters (21 feet) by 2070.

The ocean is coming for us. Global sea levels are now rising by 3.4 millimeters per year, up from an average rate of 1.4 mm per year last century. In just 80 years, the ocean could be a full 1.3 meters (4.3 feet) taller than it is today. A February 2018 study showed ocean levels rose 7 cm in 25 years, and the rate is increasing. "This acceleration, driven mainly by accelerated melting in Greenland and Antarctica, has the potential to double the total sea level rise by 2100 as compared to projections that assume a constant rate, to more than 60 centimeters instead of about 30," Professor Steve Nerem told CNN. https://www.mnn.com/earth-matters/climate-weather/blogs/facts-about-sea-level-rise http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Try Dashlane here: http://dashlane.com/simonclark Get 10% off now with my promo code: simonclark ! In this video I answer the question: 'isn't climate change supposed to have risen sea levels by now?' by looking at one dataset in some detail, and reviewing the scientific literature. Also: Kevin Costner's Waterworld. My video on stopping climate change: https://www.youtube.com/watch?v=GkbuV_a-rvs This video was light on the potential impacts of sea level rise. I wanted to focus specifically on the perception that sea levels have not changed, and spend time on the data. If you’re interested in the potential impacts then https://www.ipcc.ch/site/assets/uploads/2018/02/ar5_wgII_spm_en.pdf is a must read. Anthropogenic climate change (AGW) is a fickle bit of science, and like much of environmental science sometimes changes on (relatively) long timescales and global extent can hide in plain sight. That seems to be the case with sea level rise. The data is very clear: sea levels have been rising faster and faster over the past century, and this is not caused by natural variability. Humanity's carbon emissions are radiatively forcing the planet, causing net warming and so thermal expansion of the oceans and melting of ice sheets. It appears that this is going to become more and more painfully obvious as this century wears on, and so the sooner we take action the better.

Is unavoidable sea level rise an engineering problem, do we have the capabilities for a technological fix? John C.

Support Climate State on Patreon (Including exclusive Patreon Content Access) http://patreon.com/ClimateState Open lecture of Research Professor John C. Moore from the Arctic Centre on how we could slow sea-level rise by stabilizing the ice sheets. The lecture took place on United Nations Day on 24th October 2018 in Rovaniemi, Finland. Sea level rise will happen even if we stop using fossil fuels in the next few decades. Globally they are expected to rise by a metre this century costing tens of billions euro per year in coastal protection and forcing relocation of hundreds of millions of people and loss of many wetland ecosystems. Much of this rise is unavoidable even by cooling the climate because of ice sheet instabilities especially in Antarctica. The research, led by John C. Moore, show that we could stabilize the ice sheets by modifying the way they slide over their beds, or by increasing the buttressing that resists them as they float across the Antarctic coastline. It is not a substitute for reducing greenhouse gas emission, rather a potential solution for one symptom of warming, and one which will not work indefinitely.

The Maldives is one of the wonders of the world. Located in the Indian Ocean and made of 1192 coral islands, it is also the world’s lowest lying country. The highest natural point is just 2.4 meters above sea level. Today, one of the main problems for Maldivians is water. And it is likely to get worse with Climate Change. While Northern islands face drinking water shortages during the dry season, from April to May, most Southern islands face a different problem: flooding.The United Nations Development Programme with support from the Green Climate Fund is supporting the Government of the Maldives, to ensure that most vulnerable islands have year-round access to potable water and that they can cope with floods on their own. Nearly half of its population lives in Male, the capital of the islands, in less than 1.4 square kilometers. The rest is spread over 186 small, scattered islands. Maldivians have lived for centuries from coconuts and fishing. There are no rivers or streams on any of the islands. Except for Malé and a handful of other islands, most islands rely on rain for drinking water. Islands affected by floods and shortages of potable water receive relief from the capital island Malé. Transportation costs are high with the Maldives scattered geography. This makes emergency relief very expensive for a government already struggling economically. Climate change is expected to bring stronger storms, and longer periods without rainfall. A rise in the ocean’s temperature and acidification has had devastating effects on coral reefs, affecting tourism and fisheries, both critical to the livelihoods of most Maldivians. Damaged reefs also function less effectively as a first line of defense against sea swells and flooding. Until the nineties, Maldivians used groundwater for drinking. But over the past decade, the groundwater of most islands got contaminated. The freshwater lenses of most islands was badly affected by the Tsunami of 2004 and poorly planned urbanization. As a result, today, rainwater, together with water produced using desalination and expensive bottled water are the only potable water options. In the past ten years, the National Disasters Management Center in Malé had to send emergency shipments of water to about half of the 186 inhabited islands during the dry season. An expensive solution that sometimes can take up to two weeks to arrive. Most households have one tank of 2500L and fill it by collecting rain from their roofs. Bigger families might even have 2 or 3 tanks, since one is not enough for them to make it through the dry season. When water supply ends, households cope by borrowing from neighbors, by buying bottled water or by receiving water relief from Male.

Sea levels are rising due to global warming, and part of the reason for this is ice on land is melting and flowing into the seas. Tide gauges can measure the rising sea level, but different tide gauges show the sea level is rising at different rates in different places. Why is this?

For more WORLD NEWS "SUBSCRIBE" US MIAMI: Sea levels are rising around the world, and the latest satellite data suggests that three feet (one meter) or more is unavoidable in the next 100-200 years, NASA scientists said Wednesday. Ice sheets in Greenland and Antarctica are melting faster than ever, and oceans are warming and expanding much more rapidly than they have in years past. Rising seas will have "profound impacts" around the world, said Michael Freilich, director of NASA's Earth Science Division. "More than 150 million people, most of them in Asia, live within one meter of present sea level," he said. Low-lying US states such as Florida are at risk of disappearing, as are some of the world's major cities such as Singapore and Tokyo. "It may entirely eliminate some Pacific island nations," he said. There is no doubt that global coastlines will look very different in years to come, US space agency experts told reporters on a conference call to discuss the latest data on sea level rise. "Right now we have committed to probably more than three feet (one meter) of sea level rise, just based on the warming we have had so far," said Steve Nerem of the University of Colorado, Boulder and leader of NASA's sea level rise team It will very likely get worse in the future," he told reporters. "The biggest uncertainty is predicting how quickly the polar ice sheets will melt."

Sea Level Rise; Are we all gonna drown? There are a lot of dire predictions on the net about sea level rise. Most of these are based on global warming and melting ice caps yet these are not the major causes of sea level rise. What is? Currently we are seeing a 2.4mm/year rise in sea levels. Over 10000 years this will equate to just 24 metres. Sea level rise refers to an increase in the volume of water in the world’s oceans, resulting in an increase in global mean sea level. Sea level rise is usually attributed to global climate change by thermal expansion of the water in the oceans and by melting of Ice sheets and glaciers on land. Melting of floating Ice shelfs or icebergs at sea do not raise sea levels. Sea level rise at specific locations may be more or less than the global average. Local factors might include tectonic effects, subsidence of the land, tides, currents, storms, etc. Sea level rise is expected to continue for centuries. Because of the slow inertia, long response time for parts of the climate system, it has been estimated that we are already committed to a sea-level rise of approximately 2.3 metres (7.5 ft) for each degree Celsius of temperature rise within the next 2,000 years. IPCC Summary for Policymakers, AR5, 2014, indicated that the global mean sea level rise will continue during the 21st century, very likely at a faster rate than observed from 1971 to 2010. Projected rates and amounts vary. A January 2017 NOAA report suggests a range of GMSL rise of 0.3 – 2.5 m possible during the 21st century.

Sea-level rise is one of the inevitable results of global warming, as warmer ocean waters expand and land ice is melting and adding water to the oceans. Observations show that the seas are indeed rising, and that the rise in the 20th Century is unique in the context of the previous millennia. However, more difficult to answer is the question of how fast and how far sea level will rise in the future. The billion-dollar-question is: How stable are the ice sheets on Greenland and Antarctica? Stefan Rahmstorf obtained his PhD in oceanography at Victoria University of Wellington in 1990. He has worked as a scientist at the New Zealand Oceanographic Institute, at the Institute of Marine Science in Kiel and since 1996 at the Potsdam Institute for Climate Impact Research. His work focuses on the role of the oceans in climate change. In 1999 Rahmstorf was awarded the $ 1 million Centennial Fellowship Award of the US-based James S. McDonnell foundation. Since 2000 he teaches Physics of the Oceans as a professor at Potsdam University.

From www.athenaweb.org: Sea level rise projections for London span between a very conservative 55 cm and one metre and a half by the year 2100. But if the dreaded one-metre rise threshold can be managed by London, it will spell disaster in many other parts of the world.

Melting of Glaciers and Ice Sheets One of the most pronounced effects of climate change has been melting of masses of ice around the world. Glaciers and ice sheets are large, slow-moving assemblages of ice that cover about 10% of the world's land area and exist on every continent except Australia. They are the world's largest reservoir of fresh water, holding approximately 75% (1). Over the past century, most of the world's mountain glaciers and the ice sheets in both Greenland and Antarctica have lost mass. Retreat of this ice occurs when the mass balance (the difference between accumulation of ice in the winter versus ablation or melting in the summer) is negative such that more ice melts each year than is replaced (2). By affecting the temperature and precipitation of a particular area, both of which are key factors in the ability of a glacier to replenish its volume of ice, climate change affects the mass balance of glaciers and ice sheets. When the temperature exceeds a particular level or warm temperatures last for a long enough period, and/or there is insufficient precipitation, glaciers and ice sheets will lose mass. One of the best-documented examples of glacial retreat has been on Mount Kilimanjaro in Africa. It is the tallest peak on the continent, and so, despite being located in the tropics, it is high enough so that glacial ice has been present for at least many centuries. However, over the past century, the volume of Mount Kilimanjaro's glacial ice has decreased by about 80% (3). If this rate of loss continues, its glaciers will likely disappear within the next decade (4). Similar glacial meltbacks are occurring in Alaska, the Himalayas, and the Andes. Conclusion As CO2 emissions and climate change continue, risks to the health of the ocean will become a more prominent concern. With accelerated melting back of glaciers and ice sheets and the subsequent rise in sea level, with further decreases in oceanic pH, and with deceleration of the thermohaline circulation, there are many ways in which the delicate balance of ocean dynamics and ecosystems are being put at risk. These factors, combined with the uncertainty in predicting exactly how these impacts will interact, are causing changes in the ocean: an increasingly problematic issue for future generations

Climate change and increased atmospheric temperatures are predicted to cause a significant rise in sea level over the next 100-200 years. Scenarios that take into account rapid melting of the Greenland Ice Sheet and West Antarctic Ice Shelf warn of sea level rise of greater than 20 ft (6 meters) over the next couple centuries. This animation shows what that level of rise would (which will happen over a long period of time) might look like over a couple seconds. It uses very course scale global elevation data to visualize a rising sea affect and should NOT be considered highly accurate.

Over the last 100 years, Atlantic Ocean sea level has increased by 12-18 inches -- a rate many scientists believe will accelerate throughout the 21st century, threatening inundation of many of our nation's most valuable, historic and culturally significant coastal assets. In SEA CHANGE, South Carolina Educational Television presents diverse perspectives on the impacts of sea level rise and other environmental changes on the entire Eastern Seaboard, as experienced and anticipated in Coastal South Carolina and Georgia. Narrator Patrick McMillan takes viewers from the sands of Hunting Island State Park -- threatened by tidal and storm surge erosion -- to cities, towns and communities up and down the coast. The program asks and answers many questions. What are the immediate and long-term impacts of sea level rise on coastal communities and the people who live in them? How do we enhance infrastructure and human resiliency in the face of rising tides? Will there be winners and losers in response to the many threats? Do we have the vision and will to engage in both near- and long-term efforts to withstand nature's onslaught?

Past sea level rise is not captured by models yet, in particular the response from ice sheets in Antarctica due to global warming. Projections therefore can often be regarded to potentially underestimate future sea level rise. For example, Overpeck et al. (2006), and Hansen (2007) suggest possibilities which could eventually lead to a nonlinear response from ice sheets - accelerating the current observed sea level rise. Projections assessed by the US National Research Council (2010, pages 243-250), including Overpeck et al. 2006 http://books.nap.edu/openbook.php?record_id=12782&page=243 James Hansen on Sea Level Rise (2007) http://iopscience.iop.org/1748-9326/2/2/024002 Sea level in the 5th IPCC report (Rahmstorf, 2013) http://www.realclimate.org/index.php/archives/2013/10/sea-level-in-the-5th-ipcc-report/ IPCC AR 2013 sea level rise discussion http://www.climatechange2013.org/images/uploads/WGIAR5_WGI-12Doc2b_FinalDraft_Chapter13.pdf Sea level rise map 6 meters NASA https://commons.wikimedia.org/wiki/File:6m_Sea_Level_Rise.jpg Music: The Kyoto Connection - The Way Of Waking Up (feat.

New work from an international team including Carnegie’s Ken Caldeira demonstrates that the planet’s remaining fossil fuel resources would be sufficient to melt nearly all of Antarctica if burned, leading to a 50- or 60-meter (160- to 200-foot) rise in sea level. Because so many major cities are at or near sea level, this would put many highly populated areas where more than a billion people live under water, including New York City and Washington, DC. It is published in Science Advances.

Professor of Climate Science Gordon Hamilton walking towards GPS base station on hill overlooking Helheim Glacier 6. Mid of Hamilton checking GPS base station 7. Close-up of Hamilton's face 8. Interior of GPS base station 9. SOUNDBITE: (English) Gordon Hamilton, Professor of Climate Science, University of Maine "The Greenland ice sheet, along with the ice sheet in Antarctica, is one of the biggest potential contributors to rising sea-levels in the coming decades and centuries and one of the most amazing things that has happened in Greenland certainly in the last few years is that glaciers like this one here, Helheim glacier, have accelerated their flow speed and that's important because they are like conveyor belts that move mass out of the middle of the ice sheet and take it down to the Fjord behind us, the ocean behind us. When they get to the end they discharge ice-bergs into the ocean and that ice displaces sea water which causes sea level rise in the same way that melting ice and turning it into liquid water causes sea level rise." 10. Aerial of splits in Glacier 11 SOUNDBITE: (English) Gordon Hamilton, Professor of Climate Science, University of Maine "The Greenland ice sheet contains about 7 metres of sea level equivalent. In other words if you were to completely to get rid of the Greenland ice sheet and put all the ice that's frozen on the land's surface as liquid water into the ocean then sea levels around the world would be about 7 metres higher than they are today. Now scientists like me don't foresee a compete collapse of the ice sheet in certainly our life times and probably not for a few centuries so that 7 metre sea level rise scenario is not something we can expect any time soon but let's just say that if a small part of the ice sheet were to collapse and we got a rise of sea level by 1 metre that would have enormous implications for societies around the world, especially societies clustered near the coasts." 12. Wide aerial of Hamilton and colleague placing GPS recorder on Glacier 13. Pull out of Hamilton and colleague working on Glacier STORYLINE: As five European foreign ministers prepare to meet on Thursday in Copenhagen, the city that will host the United Nations climate summit in December, scientists in Greenland are warning how accelerated glacier melts suggest sea levels could rise across the world, threatening millions who live in coastal cities. The evidence makes compelling reading for nations due meet in Copenhagen to draw up a pact that will succeed the Kyoto Protocol, which bounds 37 industrial countries to reduce greenhouse gas emissions by 5.2 per cent of 1990 levels by 2012. On Thursday, Danish Foreign Minister Per Stig Moeller will be joined by British Foreign Secretary David Miliband, French Foreign Minister Bernard Kouchner, Swedish Foreign Minister Carl Bildt and Finland's Alexander Stubb to stress the importance of reaching a deal in December. Scientists have reported that the Helheim Glacier, suddenly and without warning, has begun accelerating, spitting icebergs ever faster into the ocean off southeastern Greenland. In just two years, a blink of an eye in a glacier's life-span, it doubled its speed and retreated several miles (kilometers) up a rift in the coastal mountains. When Helheim Glacier's speedup was mimicked by glaciers across Greenland, the alarm bells rang and experts feared the Island's vast ice sheet, a frozen water reservoir equivalent to 20 feet (7 metres) of sea level rise, was in danger of collapse.

Sifting data from 11 satellites, experts have determined that nearly a 1/2 inch (11mm) of sea level rise can be attributed to melting of ice sheets in Greenland and Antarctica since 1992 . This accounts for 20% of sea level rise during that period.
