Climate Change and the Polar Vortex: Why These Extremes Are Becoming More Common Introduction: From Weather Event to Climate Signal Polar vortex disruptions are often described as isolated winter events. In reality, they are increasingly connected to long-term climate change. What we are seeing today is not just unusual weather, but a system under stress. This follow-up article builds on the polar vortex split discussion and focuses specifically on the role climate change plays in making these events more frequent, more intense, and more persistent.

The Arctic Is Warming Faster Than the Rest of the Planet The Arctic is heating up at more than twice the global average. This process is known as Arctic amplification. Sea ice is shrinking rapidly Snow cover is disappearing earlier each year Darker surfaces absorb more heat This warming weakens the temperature contrast...

The Polar Vortex Split Explained: Past Events, Current Signals, and What Comes Next Introduction: Why the Polar Vortex Matters The polar vortex is not a storm. It is a large circulation of very cold air that normally stays locked around the Arctic. When it is strong, winter weather stays more predictable. When it weakens, stretches, or splits, cold air can escape far south and cause extreme weather. In recent weeks, meteorologists have been closely watching changes high above the Arctic. These changes suggest the polar vortex may be heading toward a split later this month. This article explains what that means, how often it happens, how it compares to past events like 2009 and 2019, and what we can realistically expect. This article was written using ChatGPT (GPT-5.2) as an analytical and explanatory tool. Understanding the Polar Vortex The polar vortex exists year-round, but it becomes strongest in winter. It forms in the stratosphere, many kilometers above the surface. ...
