The ice cover in Greenland – the second largest ice body in the world – cracks more quickly than ever in response to the collapse of the climate, a I found the study.
Researchers used 8000 3D surface maps of high -resolution commercial satellite images to assess the development of cracks on the surface of the ice cover between 2016 and 2021.
They found that the cracks-tears are open in icebergs-and it increased significantly in size and depth over the five years and at a faster rate than previously discovered.
“The biggest thing I was surprised by the speedy occurrence of this.” One of the previous studies showed changes on the scale of decades … and now we offer that this happens on five -year ranges. “
Since 1992, Greenland has seen it 14 mm of sea level rise. According to scientists, this is due to the increased melting of the ice in response to the hottest weather, and the increased ice flow in the ocean as in response to the hottest ocean temperatures, both of which are driven by the collapse of the climate.
We are confident that the crack openings are linked to accelerating the ice cover. We have known for several years that the ice cover has been greatly accelerated since 1990, and we understand widely that this is linked to the ocean warning. “
It is hoped that the high -resolution maps used in the study will start in feeding in other research in order to increase the rise in sea level.
“Many of our wide models are struggling to calculate a lot of what we call dynamic instability,” he said. “These are things related to moving the ice and moving faster … dynamic instability caused a potential one meter of sea level by 2100, and a height of 10 meters of sea level by 2300.
“Therefore, we strongly need to be more able to display sea level rise, because we need to be able to plan, to reduce and adapt to sea level and adapt to it over the next three centuries.”
