It’s official – the Earth has schizophrenia! The North Pole’s Arctic ice pack reached record lows.

Meanwhile the South Pole’s Antarctic ice pact reached record highs.

Huh?

While you wait impatiently for winter, hoping for a cooler winter than last year, it’s fun to think about where it gets really cold – the North and South Pole. They have had weather as weird as the US.

Not surprisingly, just as the US has had record warmth, so has the Arctic. As a result, this summer saw a record-breaking melting of the northern sea ice.

There still was a lot of sea ice floating around, an estimated 1.39 million square miles of the stuff. Unfortunately, this was 1.32 million square miles below the 1979 to 2000 average, almost half the normal amount.

Ten days later, the Antarctic, which was experiencing the end of the Southern Hemisphere winter, expanded to the greatest amount ever recorded. It reached 7.51 million square miles, about 20,000 miles more ice than average.

Oddly enough, the reason for both was strong winds. In the Arctic, a huge storm in early August shattered the sea ice and spewed it south into the warmer waters of the Pacific. Meanwhile in the Antarctic, the circumpolar winds that blow around the South Pole were super strong, trapping all the cold air and creating intense freezing.

All of this is part of a long-term trend. According to scientists, the Arctic sea ice has been shrinking for decades while at the same time the Antarctic ice has been growing. It hasn’t balanced out, however. The Arctic has averaged losing an area the size of Indiana each year while the Antarctic has grown an area the size of Connecticut each year.

Still, for those that worry about Arctic ice, there is some good news. Autumn is finally cooling off and freezing the northern ice pack. The melting ice cap makes headlines. No one reports on how much it grows. It’s growing back at a rapid rate. There may be some long-term concerns but, for now, the North Pole is once again becoming a winter wonderland.

Are you a weather watcher? Welcome to “Weather Whispers” by James Garriss and until recently, Evelyn Browning Garriss. With expertise and humor, this column covers everything weather—from weather forecasts to WHY extreme weather happens to ways that weather affects your life from farming to your grocery bill. Enjoy weather facts, folklore, and fun!

With heavy hearts, we share the news that historical climatologist and immensely entertaining Almanac contributor Evelyn Browning Garriss passed away in late June 2017. Evelyn shared her lifetime of weather knowledge with Almanac editors and readers, explaining weather phenomena in conversation and expounding on topics in articles for the print edition of The Old Farmer’s Almanac as well as in these articles. We were honored to know and work with her as her time allowed, which is to say when she was not giving lectures to, writing articles for, and consulting with scientists, academia, investors, and government agencies around the world. She will be greatly missed by the Almanac staff and readers.
