The Arctic will saw an ice-free summer in early 2035

A new study published in the journal Nature Climate Change has used a new and improved model based on the last intercultural period to suggest that shallow pools of rain and molten water could be free of sea ice by early 2035.

Every year Arctic sea ice fluctuates with the seasons, it expands as the sea surface freezes during the winter months, covering nearly the entire Arctic Ocean, around 6 million sq m. It then melts in the summer months, reaching its lowest point in September.

Arctic sea ice has been declining rapidly for decades. In the summer of the 1930s, ice-covered about 3.8 million square meters, but this summer, sea ice-covered about 2.8 million square meters.

During the last intercontinental period, about 127,000 years ago, the Arctic had high temperatures that scientists have been wondering for decades. To date, computer models have not been able to mimic the warmest temperatures during the last intercontinental period.

But now climate model researchers at the Hadley Center in the UK Met Office have been able to compare the state of Arctic sea ice with the current state of the last interrelated state. Their findings are important for improving the forecast of future sea ice changes.

Researchers have found that if climate change and greenhouse gas emissions are not tested, the Arctic will be ice-free by September 2035 – a month where Arctic sea ice reaches its lowest point each year. In other emission situations, researchers have predicted the disappearance of sea ice between September 2048 and September 2086.

This is consistent with the conclusion of another study from the month of April that the North Pole will experience its first ice-free summer before 2050, even if the world rapidly declines in greenhouse gas emissions in the near future. “The high temperatures in the Arctic have surprised scientists for decades. Unraveling this mystery was technically and scientifically challenging. We can begin to see for the first time how the Arctic became ice-free during the first intercontinental, said a statement from the BSAS joint lead author and Earth Systems Moderator. Advances in climate modeling mean we can create more accurate simulations of the Earth’s past climate, which in turn gives us more confidence in model predictions for the future.

The work we do not suggest is to underestimate the intensity of sea ice at the first pole. A study published last month also observed the glaciers and concluded that temperatures in the Arctic Ocean between Canada, Russia, and Europe are warming faster than researchers predicted in the climate model. Changes are happening so fast in the summer months that sea ice is likely to disappear faster than most climate models predict. We must closely monitor temperature changes and incorporate accurate climatic processes into these models, said Professor
Jens Heselzer. A geologist who worked on the study, published in July, said in a statement.
