What will happen to the earth if the ice sheets in the south and north poles all melt?

After global warming, the number of Arctic ice sheets has drastically decreased, such as the sea ice off the coast of Alaska in the United States, which has retreated to the north for hundreds of kilometers. The decrease in the number of ice sheets is extremely unfavorable for polar bears to prey. Polar bears' favorite food is seals, especially ringed seals. They are used to lurking on the ice sheet to hunt. Usually, the polar bear will lie on the ice and wait silently. When the seal sticks its head out for air, the polar bear will slap it to death, then drag it onto the ice and eat it. The reduction of the ice sheet has made polar bears lose a lot of opportunities to "sneak attack" seals. Without ice sheets, they can't hide their huge bodies. Now, it is often the case that the polar bear is not close to the seal, and the seal sees the polar bear from the flickering and shaking sea water, and then runs away. As a result, seals, like their slippery skin, are becoming more and more difficult to catch. Finally, the polar bear had to go home hungry. Life will find its own way. This article is an eternal truth. Polar bears can't stay hungry. In 214, scientists saw that in the extremely cold winter, they had found a new food for themselves-dolphins. Although dolphins are common animals in the Arctic Circle in summer, in winter, there are not many dolphins entering the Arctic Circle, especially when they are preyed by polar bears. In April 214, it was the first time that scientists observed that dolphins entered the polar bear's diet. Moreover, the first polar bear who dared to eat dolphins not only ate happily, but also had the habit of storing food. After eating the first dolphin, it seems that it wants to store the second "trophy". This behavior of storing food has rarely been found before. Climate warming has changed the ecosystem and species relationship in the Arctic Circle. It is precisely because the Arctic is getting warmer and warmer in winter that dolphins will go further and further on their way north and finally meet polar bears. This is a dolphin tragedy, but it is a great blessing for polar bears. Otherwise, polar bears may really starve to death. It is not only animals that are troubled by climate warming, but also human beings are having a headache for this problem. Transporting ice to the South Pole The South Pole is the coldest place on earth, and scientists especially understand this. Therefore, they tried to use this natural freezer to store some important samples that need to be refrigerated, such as corals, marine sediments and confidential files that are about to disappear. However, due to the warming of the climate, the temperature has also risen when it is used as the site of natural ice storage, which will have an adverse effect on the refrigerated samples. In 1994, they chose a glacier as a future sample storage point. As a result, in 25, the temperature in the same place rose by 1.5℃ when measured again. Scientists are worried about the speed of temperature rise. They hope to prepare for the establishment of the Antarctic icehouse from now on. Therefore, scientists decided to start transporting ice to the South Pole in order to better protect the Antarctic ice bank. It is not easy to transport ice to the South Pole. First of all, where does a lot of ice come from? And what tools are used to transport ice to the South Pole? These are all problems that cannot be solved at present. However, French scientists have become "pioneers" in transporting ice to Antarctica. They use special drills to extract cylindrical ice cores from glaciers in mountains around the world, such as the Alps. They dug tunnels in the glacier so that the ice cores could be transported out piece by piece. Moreover, in order to better preserve the ice core, they also used a specially designed freezer and used a helicopter to transport the ice core to the South Pole. But French scientists don't simply transport ice to the South Pole. In fact, the ice core itself is also very valuable for scientific research. Because the ice core is formed by the condensation of ice and snow for thousands of years, there will be some small bubbles in the ice core, which preserves the air samples when the ice is formed. By analyzing these samples, we can know the atmospheric composition at that time. Transporting the ice cores of various mountains and rivers to the South Pole for preservation provides excellent conditions for future people to study our air. Ice core can not only make the temperature of Antarctic sample storage point colder, but also be an important climate data. It seems like a "cold joke" to transport ice to the South Pole, but in fact, it is a more reasonable thing. Polar bears began to eat dolphins, and humans began to transport ice to the South Pole. These are the new changes brought by climate warming to the North and South poles. Source: the mystery of science
