Scientists make startling discovery after analyzing historic photos of Antarctic ice shelves: ‘An unambiguous signal’
They could miss a black and white air image that retreated on 1966. The photographer is imagined to be a member of the US Navy, which probably maps the view of Antarctica. However, years later, a few researchers noticed something unusual.
This frozen frame seemed to show that the Word ice shelf caused.
The old photograph turned out to be an important clue that could reshape our understanding of Antarctica’s melting crisis and show us why it could cost us.
What’s happening?
Researchers at the University of Copenhagen, Institution partner In a version, this vintage photos compared more with more satellite images. What they found was quiet but worried: Word ice shelf was not only melted from the surface – he was worn out. The hot ocean waters took out, shifted under the ice, sliced inside.
With the findings of the team published In April, in April, the relevant author Mads Dømgaard announced in the publication of the university: “We identified a few new ice shelf collapse on other ice shelves, but more importantly, the data set gave us many fixing points to reveal how advanced collapse.”
Dømgaard says the source can be used to evaluate the shelves that can collapse or already collapse.
Joint writer Anders Anker Bjørk, “ice shelf collapse may be slower than we think,” he added that they found the process. But Bjørk, “This longer process will make it difficult to reverse the tendency after the beginning. This is a clear signal to give priority to stopping greenhouse gas emissions rather than a time in the future.”
Why important?
Worde was not too big to start – losing only the sea levels hit the millimeter – but gave scientists a look at the future.
Larger ice shelves, such as Ross or Ronne, can be much worse with chain reaction. These shelves currently provide a stabilizing force and it can be difficult to prevent further damage after being broken once.
Therefore, tools that can help researchers have previously identified symptoms of collapse may be really important. They can buy us more time and offer stronger motivation to make a change.
What can be done?
Such studies look at the Word ice shelf in depth, promoting more effective lightening and adaptation efforts. As BJøRK points out, the findings of the team underline the urgency to capture heat in our atmosphere of governments and coalitions and reduce ice melting pollution. In addition, they can help state officials and community defenders to better prepare for the effects of rising sea levels by updating flood guidance, re -processing zoning regulations and re -establishing and reinforcing the critical infrastructure.
But maybe these activities do not fall under your personal opinion? Individual choices can still accumulate, especially when organized. Residents can make Support For policies that reduce emissions, ask local authorities how they are preparing for the rise of sea level and use clean energy options when they are available.
This photograph seemed to be not touching for decades. But he caught something big. And determined people went to the next step. What will happen next – that’s still up to us.
