As the climate change continue to heat up the Earth, glaciers are melting. Glaciers are massive ice rivers existing over land, including all the world’s major mountain ranges, and in Greenland and Antarctica. The new research suggests that the world’s glaciers are disappearing more quickly than scientists previously estimated, and they could contain up to 20% less water than scientists had thought. If glaciers are smaller than previously thought, then humanity is that much closer to a future where more than a billion people who rely on glaciers will need an alternative source of water. Rapidly melting glaciers can also cause catastrophic floods and landslides.

In a recent research by scientists at the Department of Geography, Environment and Geomatics of University of Ottawa, they found that 85% of the 1,700 glaciers in the Northern Hemisphere (including U.S., Canada, Greenland and Russia), retreated between 2000 and 2020. Glacial melt is responsible for about one third of the sea level rise that has occurred so far due to global warming. New research predicts that further mountain glaciers melting would contribute to about an additional 10 inches to global sea levels in the future. A glaciologist at Dartmouth College, Mathieu Morlighem, said, “This (10 inches) may sound like a big number, but it’s very small compared to how much sea level rise we’re predicting at the end of the century.” The largest driver of future sea level rise is the melting of enormous ice caps over Greenland and Antarctica.

The arctic region is a key driver of global climate patterns. In the summer of 2022, three peer reviewed research papers were published, all of which showed the systems that have kept the arctic stable for thousands of years are now collapsing far more quickly than previous analysis and modelling had suggested. A fourth paper, published at the same time, shows us what the consequences are likely to be. This video assesses all four, in the video published by Just Have a Think, as “Arctic System Collapse? Devastating new research“, below:
As the climate crisis worsens, some of the world’s largest ice sheets in Greenland are rapidly melting, causing global sea levels to rise. For thousands of years, ice sheets would melt and glaciers would slowly slide into the sea. But the ice was replenished by snowfall, maintaining a relative balance. Now, warmer water is one factor melting ice shelves more quickly. Eric Sorensen explains how much zombie ice — areas of glaciers that are not being replenished with new ice as they melt — is driving up waters, and which Canadian communities are set to be directly affected, in the video published Aug 30, 2022, by Global News, as ““Zombie ice” to raise sea level as Greenland Ice sheet melts“, below:
Scientists published a new study in the journal Nature Communications, in which they show that Greenland’s ice sheet is melting at such a fast pace that it’s heightening worldwide flood risks. The study, which was published on Monday, November 1, found that the Greenland ice sheet has lost more than 3.5 trillion tons of ice over the past decade, which increased global sea levels by one centimeter. This one ice sheet contains enough ice to raise global sea levels by 6 meters, or 20 feet, and it has been experiencing an increasing number of extreme melting events over the past 40 years. The new research is the first to use satellite data to detect Greenland ice sheet runoff. The satellite images showed significant annual variation in ice melt and showed that heat waves were increasingly a major cause of ice loss — above and beyond global temperature increases. In 2012 alone, for example, when changes in atmospheric patterns caused unusually warm air to hover over the ice sheet for weeks, 527 billion tonnes of ice was lost. Lead author of the study, Thomas Slater of the University of Leeds, said: “As our climate warms, it’s reasonable to expect that the instances of extreme melting in Greenland will happen more often.” in the video published by TomoNews US, as “Greenland’s Ice Sheet Is Melting Faster Than Ever“, below:
Melting ice in Greenland will inevitably lead to a major rise in the world’s sea levels, a new study has warned. According to researchers, the amount of global warming which has already occurred will cause a minimum sea-level rise of 27cm from Greenland’s ice alone – regardless of any future action on climate change, in the video published by Sky News, as “Melting ice in Greenland will cause major sea-level rise, scientists warn“, below:
Climate change’s connections with the extreme heat and weather events in the U.S. and around the globe have been well established. But climate change is also having a measurable impact on a much slower-moving development: the loss of glaciers and the melting of the ice. Miles O’Brien brings us this update on a scientist’s quest to chronicle what’s happening with one of the most important glaciers, in the video published by PBS NewsHour, on July 25, 2022, as “Scientists measure how quickly crucial Antarctica glacier is melting“, below:
Several days of unusually warm weather in northern Greenland have triggered rapid melting, made visible by the rivers of meltwater rushing into the ocean, in the video published by CNN, as “Deeply concerning to scientists’: Greenland’s ice is rapidly melting in warm weather“, below:
Greenland’s ice melting as of 2022 is dramatic. It’s sheet has lost 4,700 gigatons of ice since 2002, enough to submerge the entire U.S. under half a meter of water, according to a Polar Portal study. Within the overall trend, there was actually a small increase in ice high on the central region of the ice sheet, but ice loss is most severe along the West Greenland coast. The study used satellite data from GRACE (Gravity Recovery And Climate Experiment) and GRACE Follow On satellites to outline the dramatic changes in the ice, describing how the loss was most extreme along the edge of the ice sheet, where ice is thinning, and concluding that the melt has directly contributed 1.2 centimeters to sea level rise. Climate scientist Andrew Shepherd, cited by Space.com, explains that for every centimeter rise in global sea level, another 6 million people are exposed to coastal flooding around the planet, in the video published by TomoNews US, as “Greenland Ice Melting 222: Arctic Ice Loss at 4,700 Gigatons in Two Decades“, below:
What is the coldest weather you have endured? No matter how cold, it cannot compare to Antarctica, where temperatures can approach minus 128.6 degrees Fahrenheit or minus 89.2 degrees Celsius! However, the cold in Antarctica is nothing compared to the terrifying new discoveries scientists are making in Antarctica! Even NASA is involved in these amazing discoveries! What have scientists discovered in the cold expanse of Antarctica? How does it affect you where you live? Join us as we bring you terrifying new discoveries scientists have made under the ice of Antarctica! Many people know Antarctica is covered in ice. In fact, there is ice as far as your eyes can see in any direction. However, not many people know the place was not always covered in ice! The continent lay over the south pole without freezing for almost 100 million years. While the South Pole records average winter temperatures of 78 degrees Fahrenheit below zero, evidence suggests that Antarctica used to be as warm as Italy and covered by a green expanse of rainforest! Then, about 34 million years ago, a dramatic shift in climate happened at the boundary between the Eocene and Oligocene epochs. The warm greenhouse climate, stable since the extinction of the dinosaurs, became dramatically colder, creating an “ice- house” at the poles that have continued to the present day. Just what caused the climate shift from rainforest to an icebox is a question scientists are trying to answer! The answer is crucial because it should tell us more about how the climate responds to major controls like changes in the Earth’s orbit around the sun and the concentration of greenhouse gases in the atmosphere. Suppose you wonder how scientists could measure the temperature of Antarctica millions of years ago with a degree of accuracy. In that case, they do so by studying tiny microfossils in layers of deep-sea mud. This allows them to record climate changes over, in the video published by Future Unity, as “Scientist’s Terrifying NEW Discoveries Under Antarctica’s Ice“, below:
Scientists studying the melting Greenland ice sheet say dramatic sea level rises are inevitable, even if we stop burning fossil fuels. Last year saw record-breaking natural disasters, but a new UN report says many could have had their impacts reduced. What does all this mean for attempts to deal with climate change?
