Unveiling the Alarming Ice Loss from Greenland's 79° N Glacier
Enormous Ice Loss from Greenland Glacier: A Climate Crisis Unfolds
The Greenland Glacier, a massive ice sheet covering vast stretches of northeastern Greenland, is facing a dire situation. Recent research conducted by the Alfred Wegener Institute reveals alarming rates of ice loss from the 79° N Glacier. Let’s delve into the details and understand the critical implications for our planet.
The Melting Glacier: A Disturbing Reality
Ground-Based Measurements and Radar Insights:
Ground-based measuring devices and advanced aircraft radar have meticulously tracked the Greenland Glacier’s ice thickness.
Since 1998, the glacier has experienced a staggering 160-meter decrease in thickness.
The primary culprit? Warm ocean water flowing beneath the glacier tongue, relentlessly melting the ice from below.
Surface Lakes and Massive Channels:
Rising air temperatures have triggered the formation of lakes on the glacier’s surface.
These lakes channel water through massive channels within the ice, ultimately draining into the ocean.
The impact is profound: the glacier’s integrity is compromised, and its ice mass dwindles.
The Astonishing 500-Meter Channel:
Perhaps the most striking finding: a 500-meter-high channel beneath the ice.
Remarkably, the ice above this channel is only 190 meters thick.
This phenomenon underscores the influence of warm ocean inflow and atmospheric warming on the glacier.
Thinning Glacier Tongue:
Near the transition to the ice sheet, extremely high melt rates prevail.
The floating glacier tongue has lost a staggering 32% of its thickness since 1998.
The urgency of the situation cannot be overstated.
Large Channels and Glacier Thinning:
Channels have also formed on the glacier’s underside, likely due to water drainage from vast lakes.
These processes contribute significantly to the glacier’s thinning over recent decades.
Surprisingly, melt rates decreased after 2018, possibly due to a colder ocean inflow.
Scientific Insights and Urgent Action:
Prof Dr. Angelika Humbert, a key researcher, emphasizes the gravity of these findings.
Understanding the impact of climate change on glaciers is crucial.
Insights from this study will aid scientists in predicting and mitigating ice loss globally.
The Greenland Glacier serves as a stark reminder of our planet’s vulnerability.
Preserving Our Ice Resources:
The study underscores the urgent need for action.
Combatting climate change is essential to safeguard our valuable ice resources.
By studying these processes, we can work towards preserving the Greenland Glacier for future generations.
In conclusion, the enormous ice loss from the Greenland Glacier is a wake-up call. Let’s act swiftly to protect our delicate ecosystems and secure a sustainable future. 🌍❄️

Measuring instruments and aircraft radar data placed in the far northeast of Greenland show how much ice the 79° N glacier is losing. The thickness of the glacier has decreased by more than 130 meters per year since 1998, according to measurements led by the Alfred Wegener Institute.
