A recent study states that the ice shelves in North Greenland have decreased in volume by 35%, resulting in significant impacts on the rise of sea levels.
Researchers have previously believed that the glaciers in North Greenland were not changing significantly, which is important because they hold a significant amount of ice that could potentially contribute to a significant rise in sea levels. However, a recent study revealed that ice shelves in the area have decreased by over 33% in the past 50 years due to increasing temperatures. Scientists warn that if this trend continues, there could be severe repercussions for the glaciers and the Earth.
A recent study published in Nature Communications utilized satellite imagery and climate modeling to determine that the ice shelves in North Greenland have experienced a 35% decrease in total volume since 1978.
the polar ice sheets that float on the ocean’s surface
The floating sections of polar ice sheets are known as ice shelves.ice sheets — a form of glacier — that float over water. Three of those shelves in North Greenland have “completely” collapsed, researchers said, and of the five main shelves that remain, they said they have seen a “widespread increase” in how much mass they have lost, mostly due to the
Ocean warming.
The rise in ocean temperature intensifies the melting of ice.
1.5-degree Celsius global warming threshold breached by 2030
This year, the World Meteorological Organization predicted that by 2030, the Earth will surpass the 1.5-degree Celsius threshold for global warming.hottest year ever1.5 degrees Celsius
Over the next five years, there will be recorded data showing that the planet has surpassed a 1.5 degree Celsius increase in temperature compared to pre-industrial levels. In September, the Copernicus Climate Change Service of the European Union released a report stating that this summer marked a 1.5 degree Celsius rise in Earth’s temperature.
