Have you ever wondered what would happen if all the ice on Earth melted? Let’s explore this fascinating topic and understand the potential impacts on our planet.
Our planet’s water is mostly salty, with only about 3% being fresh water. Interestingly, 70% of this fresh water is frozen, forming massive ice reserves. If you imagine spreading all this ice in a layer 1,000 meters thick, it would cover North America entirely!
On land, ice appears as glaciers, ice sheets, permafrost, and snow. In the Arctic, which is mostly ocean, ice floats as sea ice, like icebergs. This sea ice is in direct contact with warming ocean waters, making it the first to melt as global temperatures rise. In 2016, NASA reported record-low levels of Arctic sea ice.
As the ice melts, new shipping routes may open, allowing easier travel from Europe to Russia over the North Pole. While this might benefit shipping companies, it poses a serious threat to marine animals like polar bears, walruses, and seals, whose habitats are disappearing. Ocean creatures like bowhead whales and narwhals are also affected.
With melting ice, energy and oil companies are eager to explore the Arctic for untapped resources. They use seismic blasting, which involves shooting air explosions into the water to map the ocean floor. This practice harms the Arctic ecosystem, causing physical trauma and habitat disruption for whales.
While melting sea ice doesn’t significantly raise sea levels, land-based ice is a different story. Over 95% of Earth’s ice is on land, mainly in Greenland and Antarctica. If all this ice melted, sea levels could rise by about 70 meters, causing catastrophic consequences.
Many major cities like Tokyo, New York, Mumbai, Shanghai, and Jakarta are near coastlines. Even a small rise in sea level could lead to trillions of dollars in flood damage each year. A 10-meter rise could displace over 630 million people, while a 25-meter rise could leave 1.4 billion people homeless.
Rising seas would flood much of the U.S. Eastern Seaboard, parts of the West Coast, all of Florida, and significant areas in Asia, including Bangladesh and northern China. Australia could even see a new inland sea.
Ice at the poles reflects sunlight back into space. As ice melts, less sunlight is reflected, leading to more warming. The dark ocean absorbs more sunlight, worsening the situation. Melting ice can also disrupt ocean currents, affecting marine life and the oxygen we breathe.
We recently visited the Arctic to see the changes firsthand and documented our findings in a documentary called “The End of the Arctic.” It highlights the struggles of an Inuit community against oil companies and the Canadian government to protect the Arctic from climate change and seismic blasting.
You can help by raising awareness, sharing information, and signing petitions to stop seismic blasting in the Arctic. Join the movement to protect the Arctic and our planet, and stay informed with more science updates.
Using a large container, water, and various objects to represent land and ice, create a model to demonstrate how melting ice affects sea levels. Observe and record the changes when ice melts on land versus in the ocean. Discuss your findings with your classmates.
Choose an Arctic animal, such as a polar bear or narwhal, and research how melting ice impacts its habitat and survival. Create a presentation to share your findings with the class, highlighting the challenges these animals face and potential solutions.
Participate in a classroom debate on the topic: “Should countries prioritize economic benefits from new shipping routes and resource exploration in the Arctic over environmental protection?” Prepare arguments for both sides and engage in a respectful discussion.
Work in groups to design a campaign aimed at raising awareness about the consequences of melting ice and climate change. Create posters, social media posts, or short videos to educate your peers and community about the importance of protecting the Arctic.
Conduct an experiment to understand how ice reflects sunlight. Use a flashlight, a mirror, and a dark surface to simulate the reflection of sunlight by ice. Discuss how the reduction of ice affects global temperatures and climate patterns.

You’ve likely heard about the effects that climate change is having on our planet, particularly in the Arctic, which is warming twice as fast. But what would actually happen if all the ice melted on Earth? I can help with that.
When we drink water, we consume fresh water, which makes up only about 3% of all the water in the world. Of that 3%, a significant portion—70%—is frozen, totaling around 30 million cubic kilometers of frozen water. This amount is so vast that if it were spread out in a layer 1,000 meters thick, it would cover North America.
On land, frozen water forms glaciers, ice sheets, permafrost, and snow. However, the Arctic is largely ocean, where it takes the form of floating sea ice, such as icebergs. Because this ice is in direct contact with warming waters, it will be the first to melt as global temperatures rise. In fact, NASA reported that the extent of Arctic sea ice was at its lowest ever recorded for several months in 2016.
As the world warms and the ice melts, shipping routes may open up, allowing for easier passage from Europe to Russia over the North Pole. While this may benefit certain shipping companies, it poses a significant threat to marine species like polar bears, walruses, and seals, whose habitats are disappearing. Ocean-dwelling animals, such as bowhead whales and narwhals, are also affected by these changes.
As sea ice melts, energy and oil companies are taking the opportunity to search for untapped resources in the Arctic. They use a process known as seismic blasting, which involves shooting air explosions into the water to map the ocean floor and locate oil. This practice has detrimental effects on the entire Arctic ecosystem and can cause physical trauma and habitat displacement for whales.
In terms of sea levels, melting sea ice itself won’t significantly affect them, as floating ice already displaces roughly the same amount of water as it would produce when it melts. However, more than 95% of Earth’s ice is land-based, primarily found in massive ice sheets covering Greenland and Antarctica. If all this land ice were to melt, sea levels would rise by approximately 70 meters, which would have catastrophic consequences.
Many of the world’s largest cities, including Tokyo, New York, Mumbai, Shanghai, and Jakarta, are located along coastlines. Even a small rise in sea level could result in trillions of dollars in flood damage annually. A rise of 10 meters would displace over 630 million people, nearly 10% of the global population, while a rise of 25 meters could leave around 1.4 billion people homeless.
The rising seas would inundate much of the U.S. Eastern Seaboard, large portions of the West Coast, the entire state of Florida, and significant areas of Asia, including Bangladesh and northern China. This would also create a new inland sea in Australia.
At the North and South Poles, ice plays a crucial role in reflecting sunlight back into space. However, as the world warms and ice melts, less sunlight is reflected, leading to further warming. The dark ocean absorbs more sunlight, exacerbating the situation. This melting ice can also disrupt ocean currents, which are essential for transporting nutrients and chemicals around the globe, ultimately affecting marine life and the oxygen we breathe.
We recently traveled to the Arctic to witness the current state of affairs firsthand and were shocked by what we found. We documented our experiences in a documentary titled “The End of the Arctic,” which highlights an Inuit community’s struggle to defend their rights against oil companies and the Canadian government while trying to protect the Arctic from the severe impacts of climate change and seismic blasting.
You can help raise awareness by sharing this video and signing our petition to urge the government to prevent seismic blasting in the Arctic, which would have long-lasting effects on wildlife and the Inuit people living in Northern Canada.
