Read more about our fact-checking work here. Using 20 years of recently declassified satellite data, scientists calculated that the worlds 220,000 mountain glaciers are losing more than 328 billion tons (298 billion metric tons) of ice and snow per year since 2015, according to a study in Wednesdays journal Nature. WebThe age of the oldest glacier ice in Antarctica may approach 1,000,000 years old The age of the oldest glacier ice in Greenland is more than 100,000 years old The age of the oldest Alaskan glacier ice ever recovered (from a basin between Mt. Because rocks of that age are rare, we don't know much about the intensity or global extent of this glaciation. Glaciers have short response times and therefore react quickly to climate change. We mapped a complete set of glacier areas from the Little Ice Age (LIA) using very high-resolution satellite imagery (30-cm) within Glacier National Park, a region that encompasses over 400,000 hectares. For warming between 2-4C, the Greenland Ice Sheet will contribute 0.34 m of sea level rise per degree of warming, and it has a total sea level contribution of up to 6 m17. I mapped 195 distinct glaciers on the northern tip of the Antarctic Peninsula alone, including outlet glaciers that drain the Antarctic Peninsula Ice Sheet and separate mountain glaciers and ice caps.
