The loss of Arctic sea ice has a minimal impact in severe winter weather

Dramatic ice loss in the Arctic caused by climate change has had minimal impact on harsh winter weather in Asia and North America, new research shows. The potential relationship between the loss of Arctic ice and extremely cold weather, such as freezing temperatures that could straddle the United States during the winter months, has long been studied by scientists.

Observations show that with the loss of regional sea ice, parts of Asia and North America are often exposed to extremely cold and dangerous winter conditions.

However, previous climate modeling studies have shown that reduced sea ice may not fully explain winter. Now a new study sheds new light on the relationship between sea ice loss and winter.

For this research, the international team combines observations from the past 40 years with the results of sophisticated climate model experiments. They found that observations and models agreed that regional and winter sea ice reduction often coincided.

They found that the relationship between reduced sea ice and extreme winters was obtained from average latitudes, because both were driven by the same large-scale atmospheric circulation pattern. Most importantly, reduced sea ice has a minimal impact on whether severe and severe winters occur.

The correlation between reduced sea ice and winter does not mean that one causes the other. We show that the real cause is a change in atmospheric circulation that drives warm air in the Arctic and cold air in mid-latitudes. In recent decades, climate change has witnessed warming temperatures in the Arctic that have caused a sharp decline in sea ice cover.

This decrease in sea ice causes an increase in open water areas, which causes the oceans to lose more heat to the atmosphere in winter and possibly change the weather and climate outside the Arctic. Recent studies have shown that reduced sea ice or Arctic warming has contributed to the recent winter in the midline, and that winter is becoming more frequent and severe because sea ice continues to decline due to climate change.
