The story begins with a typical Arctic weather scenario: a melting glacier, a giant landslide, and a massive tsunami wave, which in turn triggered a series of events that would shake the scientific community to its core. In the remote region of Dickson Fjord, eastern Greenland, a 4,000-foot-tall mountain began to collapse, sending a huge amount of debris tumbling into the water. The resulting mega-tsunami set off a chain reaction that would last for nine days, causing a seismic hum that resonated across the globe.

Imagine, if you will, the sound of a giant piano string being plucked, but instead of stopping after a few seconds, the note continues to reverberate for nearly a week. That was the phenomenon that scientists were trying to explain – a vibration that remained steady and constant, unlike any earthquake signal they had ever recorded before. It was as if the very earth itself was humming along to an otherworldly tune.

The hum was traced back to the massive landslide, which was itself triggered by the melting glacier, a result of human-caused climate change. The glacial melting caused the rock face to become increasingly unstable, until it finally gave way, sending rocks and debris crashing into the fjord.

Question: What if this assumption is wrong? What if the melting glacier is just the tip of the iceberg, and there are many more such environmental catastrophes waiting to happen?

The scientists, however, were far from puzzled. Instead, they were excited to have stumbled upon a phenomenon that could provide valuable insights into the workings of the Arctic environment. The research team, comprising 68 scientists from 15 countries, worked tirelessly to collect data and piece together the events that led to the hum.

As the team dug deeper, they discovered that the hum was caused by a phenomenon known as a seiche, where the water in the fjord became trapped and began to slosh back and forth, creating the seismic energy that echoed across the globe.

Question: What might the long-term consequences of this event be? Will we see more frequent rock collapses in permafrost slopes as the climate warms?

But the hum was not the only surprising revelation. The research team also found that the Arctic is entering “uncharted waters,” with new areas becoming prone to landslide and tsunami events. This raises questions about the potential consequences of climate change, not just for the Arctic, but for the entire planet.

Question: How can we prepare for the unpredictable and potentially devastating effects of climate change?

In the end, the mystery of the hum was solved, but the warning it sends is clear: the Arctic is a region that is rapidly changing, and we must adapt to these new realities if we hope to avoid the devastating consequences of climate change.
