In 2025, winter sea ice in the Arctic hit a record low of 5.53 million square miles, as reported by NASA and the National Snow and Ice Data Center. This marks a significant decline of 1.1 million square miles compared to the previous year and is the lowest extent recorded since measurements began 47 years ago. The decrease has been influenced by high temperatures, severe weather patterns, and ongoing climate change, all leading to predictions that the Arctic may face ice-free summers as early as 2050. Additionally, severe thunderstorms have been affecting large parts of the US, heightening concerns about extreme weather patterns.
The annual peak for winter sea ice in the Arctic reached a record low on March 22, 2025, covering just 5.53 million square miles, 1.1 million less than last year.
Unexpectedly decreased sea ice extent in January lost an area the size of Italy due to cyclones pushing southerly winds, causing ocean waves that broke apart the thin ice.
In late January, Arctic sea ice extent decreased dramatically due to warmer temperatures and weather patterns, compounded by climate change, suggesting potential ice-free summers before 2050.
The past weekend saw the onset of severe thunderstorms across the US, with reports of tornadoes and damaging winds, exacerbated by a warm and humid air boundary.
