A recent study revealed that the Arctic Ocean would be ice-free between 2044 and 2067, owing to the human-caused global warming. A group of researchers conducted the study at California University, Los Angeles.
Before the industrial revolution, the sea ice caps used to expand during winter and contrast in summer. But, due to rapid human-caused climate change, the ice caps are reducing by a significant level. The satellite image suggests that since 1979, the sea ice present in the Arctic Ocean reduced by a whopping 13% per decade. The observations were carried out since September 1979.
Its been a decade since the scientist communities are attempting to predict the future of the Arctic Ocean by relying on multiple climate change models. They are trying to simulate a flow chart by using the carbon emission in the atmosphere. But the predictions often face the heat of disagreement within the community. Some models even predicted that humans could see an ice-free September as early as 2026. But, some other models predicted it to be as late as 2132.
Why Does an Ice-Free September be a Possibility by 2044?
Ice has a relatively reflective surface; it reflects most of the sunlight. When a patch of ice melts completely, the water below the ice cap exposed to the direct sunlight. As the seawater are darker in colour, it absorbs more sunlight than an ice cube. As a result, the temperature in the area increased significantly. Once the temperature of the water started to grow, the remaining ice caps in the region began to melt, the researchers explained. The cycle shows exponential growth and continues until September. Scientists also warned that the Arctic Ocean warms twice as fast as the remaining globe. So it will not be a surprise if the world would see an ice-free September as early as 2044.
The study advised the world to decrease the carbon emission to postpone the unfortunate effects of climate change.
