Queen Campos Kaaba 1 hour 5 minutes ago The East Antarctic region has been shown to be less vulnerable to climate change than other polar regions. Currently, it is becoming more important due to the loss of ice mass observed in the last decades.
East Antarctic Ice Cap Contains the vast majority of Earth’s glacial ice. We’re talking about this, if it melts, sea levels could rise 52 meters! However, it is assumed to be less vulnerable to global warming, compared to the ice sheets of West Antarctica or Greenland.
The loss of ice mass in the East Antarctic region would not only lead to rising sea levels, but could also lead to an increase in extreme weather on a global scale.
A recent study published in the journal Nature, created the need to reassess the vulnerability exposed in East Antarctica against climate change. It has been observed that some of the sea basins, which had suffered great damage during the last warm period, are losing too much today.
In the research “Dynamic behavior of the East Antarctic ice sheet during the Pliocene summer”, published in the journal Nature, it was concluded that the East Antarctic ice sheet was sensitive to global warming during the Pliocene (5.33-2.58 million years).
However, most estimates indicate additional accumulation in the East Antarctic ice sheet during the 21st century. This will keep the ice layer in balance.
Looking beyond 2100, the study suggests that higher emissions scenarios lead to higher ice discharges and possibly several meters of sea level rise over the course of a few centuries. Nothing new at the moment. Even so, the loss of mass of substance can be avoided, if the Paris Agreement is followed.
East Antarctica, what do we know about it?
Antarctic ice shelves control the flow of glacial ice as it falls into the sea. This means that the rate of sea level rise on a global scale is subject to the structural integrity The floating extents of these ‘fragile’ ice sheets.
The evolution of East Antarctica is directly related to the climate variability of distant countries such as Australia.
Unlike West Antarctica, due to large-scale ice loss East Antarctica is largely unexplored. As early as August 2022, another study indicated that it might be related to the scenario. Reorganization of coastal water masses. In addition, it is a . will be related to the movement towards the poles In the summer, over the Antarctic Ocean.
Impact on Australia’s climate
The concentration of sea salt (aerosol) preserved in the La Dome ice core (East Antarctica) has been shown to have a significant association with precipitation over eastern Australia. and what does it mean? What is associated with decreased sea salt concentration in the ice core and drier conditions in eastern Australia? Equatorial displacement of westerly winds at mid-latitudes (30°-60°).
Tropical ozone hole seven times larger than Antarctica
This relationship explains a much larger change in precipitation than an El Nio Southern Oscillation (ENSO) event at the end of the spring–summer period. importance here Law Dome Ice Core Log because a 2000 year point would be needed to explain the rainfall variability in eastern Australia.
Everything is connected and science proves it every day. that is why research is needed to continue improving climate forecasts in the medium and long term, considering new variables that appear over time.
