Scientists issue warning after discovering powerful phenomenon that could cause severe flooding: 'Extreme disturbances'

Rising global temperatures have contributed to the formation of a meltwater lake on top of Greenland's 79°N glacier, which has exacerbated ice melt. 

What's happening?

Researchers recently published their observations of the lake and its effects on glacial fracturing in the Cryosphere. Since the meltwater began pooling on the surface of 79°N in 1995, drainage has caused cracks that lift the glacier. The research team noted that the lake developed due to warming temperatures, which are caused in part by human activity. 

When the water drains, it rushes toward the glacier's edge and into the ocean. Ice is fairly flexible, so scientists are looking into how the glacier maintains itself amid these conditions. 

"These are extreme disturbances within the system, and it has not yet been investigated whether the glacial system can absorb this amount of water and is able to influence the drainage itself," lead author Angelika Humbert told SciTechDaily.

Why is Arctic ice melt important?

When Arctic glaciers melt, the process causes sea levels to rise in certain countries near the equator. For example, Indonesia is expected to experience major flooding by 2050 because of this phenomenon. Pollution from sources like dirty fuels has contributed to rising temperatures that serve as "steroids" for extreme weather. This, coupled with rising sea levels, puts coastal communities around the world at risk of displacement. 

Everyday people often suffer the most despite the fact that they aren't the biggest contributors to the changing climate. Many cannot afford to completely relocate their lives if their homes are damaged by floods or wildfires. This issue is made worse by the fact that insurance companies have dropped coverage for people living in high-risk areas.

What's being done about Arctic ice melt?

Research like this helps scientists understand the full extent of glacial melting in the Arctic. Subsequently, these studies also help individuals educate themselves on critical climate issues and take action to help the planet.

People can make eco-friendly upgrades to their homes to help combat pollution and protect themselves from rising utility rates. Solar energy is one of the best ways to make your home more resilient to extreme weather when paired with battery storage.
