Not long ago, when the floating ice in the Arctic Ocean recorded the second smallest area in history, the severity of global warming increased again. Not only is the ice shrinking, it is also getting thinner and thinner, making it more vulnerable. There are even predictions that the ice will disappear from the North Pole in the future. This is reporter Ham Hyeong-gun. This is the view of the Arctic Ocean near Norway last month that was covered in ice throughout the year. As the summer wore on, the ice in the Arctic Ocean broke, floated to pieces, floated out to sea, or melted. Arctic ice partially melts in summer and freezes again in autumn, and as time passes, its condition becomes more dangerous. YTN’s data journalism team used NASA data to visualize how the Arctic sea ice age has changed over the past 36 years. The area marked in dark blue is more than 5 years old, which is relatively thick and solid sea ice. In the late 1980s, almost half of the Arctic Ocean ice was more than five years old. However, in the 1990s, the color gradually faded. Thin ice has grown, less than two years old. Since the mid-2000s, the amount of ice in a year has increased rapidly and old ice is now rarely found. The percentage of ice that had been created less than two years ago was 23% of all Arctic ice in the summer of 1987, but increased steadily to 78% this summer. On the other hand, ice that is more than 5 years old was reduced from 45% of the total area in 1987 to only 1% this year. Scientists have warned that Arctic sea ice is turning into thin ice that is more susceptible to global warming, rather than old ice that rarely melts in summer. The melting season of Arctic ice is getting longer. In the past, some ice melted in the summer and then refrozen starting in mid-September, but in the case of last year, the ice gradually freezed until mid-October. As such, the Arctic ice is predicted to gradually decrease each summer and disappear in the future. If greenhouse gases continue to be emitted as they are, several statistical predictions have recently emerged that there is a chance that the ice-free Arctic will become a reality within at least 30 years, and the Arctic sea ice may disappear in 15 years ASAP. The disappearance of Arctic sea ice due to global warming further increases the likelihood of extreme weather events and natural disasters. This is yet another warning that has reached the global village that is hesitant to reduce greenhouse gas emissions. YTN Hyung-Gun Ham[[email protected]]is. Investigation: Shin Soo-min
