Melting ice will never freeze again.
Researchers at McGill University in Montreal, Canada, discovered horrific facts about the fate of the Earth in the future.In their findings mentioned that the Arctic sea ice will be destroyed during the summer in the next 30 years.The loss of sea ice will have devastating consequences for the entire ecosystem of the Earth, especially in the Arctic.

What is the Arctic Ocean of Ice?
Sea ice is sea water in the Arctic that freezes and then melts in part every summer. This sea water will return to freezing every winter.But in the next 30 years, the melting sea of ice will not freeze again. This means that the sea ice in the Arctic is gone forever.The amount of sea ice during the Arctic summer has continued to shrink in recent decades due to global warming.

Shrinkage of the Second Smallest Ocean of Ice
Since satellite records began in 1979, the Arctic sea ice during the summer has lost 40%. Likewise with the volume, which has lost up to 70%, according to The Guardian’s report .Even so, the depreciation is considered the second smallest in 2019, the National Oceanic and Atmospheric Administration report in the United States said.

Function of the Arctic Ocean of Ice for the Earth and Its Contents
Sea ice affects the Arctic community and the wildlife in it such as polar bears and walruses.In addition, Arctic sea ice helps regulate the temperature of the planet Earth by affecting atmospheric and ocean circulation.Not only that, the sea of ice in the Arctic Ocean also affects global weather patterns.

North Pole Heats Up Faster
As the extent of sea ice in the Arctic continues to decline during this transition until it is completely gone, the impact of changes from year to year also increases. Making life more difficult for local populations and species that depend on ice.This was revealed by one researcher at McGill University , Bruno Tremblay, who is also part of the authors of this study.
When the climate changes, the Arctic heats up more than twice as fast as anywhere else on the planet.Arctic air temperatures are around 3.4 degrees above average in 2019 and are the second warmest since records began in 1900.

Strong Effects of Carbon Emissions
How often the Arctic loses its sea ice in the future depends on carbon emissions,” the study said.If carbon emissions are low, years without ice in the Arctic will only occur occasionally. Conversely, if carbon emissions are high, the Arctic Ocean will become ice free throughout the year.Thus, even if humans try to reduce carbon emissions dramatically, sea ice during the summer season may still disappear, according to the study.
“If we reduce global carbon emissions quickly and substantially, then keep global warming below 2 degrees Celsius, Arctic sea ice is likely to disappear occasionally in the summer even before 2050,” said Dirk Notz, lead author of the research who heads the ocean research group ice at the University of Hamburg , Germany.The study analyzed the latest results from 40 of the latest climate computer models and involved 21 research institutes from around the world. The research was published in the journal Geophysical Research Letters , a publication of the American Geophysical Union .
