And according to the IPCC, rising sea levels may be the culprit of the most dangerous symptoms of climate change. It has been a focus of attention in recent years, largely because of a strong decrease in the Arctic sea ice cover and modeling results that indicate that global warming could be amplified in the Arctic on account of ice-albedo feedback. I will consider the environmental, social, and economic impacts of my daily decisions and make every effort to be responsible in these areas. This means that it reflects excess radiation from the sun back into space and keeps our planet from overheating – not in the little way that it has been, but in a big way. mass of glacial land ice extending more than 50,000 square kilometers (20,000 square miles Think of it as ice in your glass of water melting. The ice loss from Greenland and … No. This is about the size of the state of Maryland. 2- Act for the planet by making global warming an urgency, reducing greenhouse gas emissions and choosing clean energy. Attributed in part to rising average temperatures, the poles are experiencing the brunt of global warming. … For example Earth's polar ice caps are mainly water ice, while Mars's polar ice caps are a mixture of solid phase carbon dioxide and water ice. There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land, but only that it must be a body of solid phase matter in the polar region. Known as polar amplification, the effects of increased solar radiation are most pronounced in polar regions. 5- Adopt a sustainable lifestyle: the collective efforts of individuals can make a huge impact for conserving resources and protecting the environment. Our adaptable earth has been here for five billion years and it will be here for five billion more without us. Luckily, this number can be offset to a degree. Antarctic ice levels may be at a new maximum, but we are still losing ice from the Arctic polar ice caps melting at an astounding rate. During the first half of the period, this rate of loss was 8,300 square miles. The answer is not readily available, but nonetheless, communities should prepare for the worst. Sea ice is important because it’s highly reflective. Gone. New snow falls on top and the snow underneath becomes even denser. Certain parts of the Antarctic ice shelf are currently melting, but this melting is outweighed by new ice accumulation elsewhere. Ice shelves are massive, floating platforms of ice that surround the ice-covered continents of Antarctica and Greenland. “I pledge to live a more sustainable lifestyle. There are no signs of a slowdown in the rate of melting, as global temperatures continue to go up. And as climate change may also lengthen hurricane season, coastal towns may experience even more deadly flooding every year. These large bodies of water absorb 90% of the Earth's total warmth, meaning that sea ice floating in the ocean are subject to higher temperatures and naturally melt as a result. Because of melting sea ice, it is likely that more polar bears will soon starve, warns a new study that discovered the large carnivores need to eat 60 percent more than anyone had realized. Since this is where polar bears, seals, and other animals in this climate live, they are losing their homes and their entire species is being threatened. INCAN CHILD SACRIFICE VICTIMS // ARGENTINA. The polar ice caps have melted faster in last 20 years than in the last 10,000. 5.2 What will be the impact on marine fisheries? NASA has estimated that the polar ice caps are melting 9% every ten years, which is an extremely alarming rate. Already, many cities and towns have explored alternatives to diffuse rising sea levels — many to no avail. A comprehensive satellite study confirms that the melting ice caps are raising sea levels at an accelerating rate. Since the industrial revolution, however, humans have been tipping that delicate natural balance. Here are eight important facts that everyone should know about our polar ice caps melting from confirmed recent scientific studies and data. Today, polar ice caps are melting six times faster than they did in the 1990s. The melting of the polar ice caps is caused by the overall increase in global temperature, and this melting can have serious consequences for all … This includes surface plankton – the surface plankton that provides much of our atmospheric oxygen and the lowest level of the food chain in the ocean. As part of the overall climate change phenomenon, the polar ice caps melting is an effect of trapped greenhouse gas emissions. This animation shows how the multi-year sea ice area, an estimation of the total volume of multi-year ice in the Arctic Ocean, has evolved from 1980 to 2012. Credit: NASA… Cookie - Terms & Conditions - Privacy Policy. According to the National Snow and Ice Data Center, sea ice reflects 80 percent of the sunlight that hits it, whereas the dark ocean water absorbs 90 percent of the sunlight that shines on it. This happens over and over again with layers of compressed, hard snow forming on top of each other. 8- Reduce energy, water and food waste, for a more equitable sharing and preservation of our resources. This is certainly the case for the Antarctic Circle. It really is that serious. When they melt, sea level isn't directly affected because this ice is already in the ocean. The GRACE mission concluded science operations in June 2017. Almost 90% is in Antarctica, while the remaining 10% is in the Greenland ice cap. Clair Parkinson, a scientist from NASA’s Goddard Space Flight Center has confirmed that “the decreases in Arctic sea ice far exceed the increases in Antarctic sea ice.”, This rate of polar ice caps melting has been being measured since 1979. Where the average global temperature may increase slightly over time, the poles oftentimes experience steeper temperature spikes. I will also share my individual sustainability efforts with others and in my community to inspire people in making conscientious choices for the planet”.

Arctic sea ice keeps the polar regions cool and helps moderate global climate. Already, cities such as Miami and London have experienced preemptive flooding. Florida? How will they adapt to rising sea levels? This is also a clear explanation for why the rate of the arctic polar ice caps melting doubled over the past few years. The complete loss of this state to global warming caused by our lavish lifestyle. A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice.. Wet. All Rights Reserved. The Earth Project is committed to being a positive force for the future of our environment, through education, research, and helping fund sustainable projects. A very dangerous way. 9- Choose local and organic products: by reducing transportation and chemicals, we make a healthy choice for us and the planet. “What was highly unusual in the recent past is becoming the new normal. More contact with humans. It has now doubled in the last half of this measurement period to 19,500 square miles per year. The composition of the ice will vary. National Geographic has actually made a graphic to show would the world would look like if this happened. Rising sea levels will threaten coastal communities across the globe, where even minute changes in sea level can flood or engulf entire cities. The burning of fossil fuels – coal, gas and oil – causes the Earth’s temperature to go up significantly. We’d lose a lot of coastal cities, but would it really be the end of the world? That is quite a serious trade off. About 15 percent of the world's oceans are covered by sea ice during part of the year. In fact, oxygen levels are predicted to decrease even further–about 3% to 6% over then next century. Ari Kelo is an Editor at The Rising, primarily covering the politics of environmental sustainability. The Polar ice caps melting may change our world maps, as a result of the flooding that is caused. Polar ice cap melting would create a rise in sea levels, and a sudden collapse of West Antarctic ice sheets could raise sea levels from 16-20 feet. In a more proximate scale, ice loss has … 10- Reduce our plastic consumption, and favor reusable and recyclable goods: Rather, he anticipates that these impacts “are happening and will be devastating for coastal communities.”. "The polar ice caps are melting six times faster than in the 1990s, according to the most complete analysis to date" (Source). Global warming deniers claim that the results concerning sea ice at a global level appear to have evened out. Scientists have confirmed that polar ice caps are melting at unprecedented and dangerous rates. We will send you all the latest blog posts from the Earth Project, as well as popular projects, news and more. Instead of reflecting 80 percent of the sunlight, the ocean absorbs 90 percent of the sunlight. Our weather is becoming more unstable and dangerous. Ari Kelo is an Editor at The Rising, primarily covering…. Not surprisingly, global sea levels are rising as a consequence of the melting ice caps. And the headline-making 2019 Arctic heatwave certainly did not help. According to NASA, “since…about 1750, carbon dioxide levels have increased nearly 38 percent as of 2009 and methane levels have increased 148 percent.”. Don’t worry, we won’t spam you or sell your information. Polar bears and melting ice: three facts that shouldn’t surprise you Posted on July 20, 2014 | Comments Off on Polar bears and melting ice: three facts that shouldn’t surprise you If I was invited by USA TODAY to discuss how climate change is affecting polar bears now – summed up in three talking points – this is what I’d say. Multi-year sea ice, or ice that has survived at least two melt seasons in the Arctic, is shrinking rapidly. The first step for front-line, coastal communities may be to recognize that the fast pace at which polar ice caps melt present a crisis beyond the arctic and Antarctic circles. The surface level of the ocean is heating much faster than the lower levels, and in the surface, oxygen is depleting at an alarming rate. The sea ice cover is one of the key components of the polar climate system. 6- Protect and respect animals, their natural habitats and biodiversity, endangered species and communities. Right now, we have been living in a much cooler time. Do share your tips for lowering carbon footprints below. Accordingly, coasts spanning the Atlantic Ocean face a unique challenge. The scientists behind the IPCC’s recent statement attest that the future may be grave for coastal communities. In the 1990s, towns became accustomed to a much slower rising sea level rate. While it’s true that we’re facing environmental challenges, we can all do our part to ensure that we do not add to the damage. The current rate of polar ice cap loss is tracking as a worst-case scenario according to the Intergovernmental Panel of Climate Change (IPCC). Since the 1990s, the speed of ice loss as increased sixfold — with a sevenfold increase in Greenland. According to the National Snow and Ice Data Center (), ice currently covers 6 million square miles, or one tenth the Land area on Earth, about the area of South America.Floating ice, or Sea Ice, alternately called Pack Ice at the North and South Poles covers 6% of the ocean’s surface (), an area similar to North America.The most important measure of ice is its … The polar ice caps are melting six times faster than in the 1990s, according to the most complete analysis to date. The Arctic ice cap has decreased since the 1960s by as much as 40%. If the temperature on earth continues to rise at its current rate the Arctic will have no ice by 2040.
