The threat from Antarctica: What is the post-ice age rise and how will it “strangle” the Earth?

The threat from Antarctica: What is the post-ice age rise and how will it “strangle” the Earth?

In an impressive study, scientists observed that That Antarctica is losing weight and the continent is rising from the ocean.

This process known as post-glacial uplift According to new research, it will Future global sea level rise.

This could reduce Antarctica’s contribution by up to 40%, or make things worse, depending on how much heat-trapping fossil fuels and ice melting we lose.

“With nearly 700 million people living in coastal areas and the potential cost of sea level rise reaching trillions of dollars by the end of the century, understanding the domino effect of melting Antarctic ice is critical,” he said. Glaciologist Natalia Gomez of McGill University;which produced the study.

In recent years, the ice in Antarctica has been very low. Gomez and his colleagues They examined the Earth’s mantle beneath the Antarctic ice sheet and found that in some areas it was brittle.

According to seismic data, this high level of viscosity leads to an unexpected rise. “Our measurements show that the solid ground underlying the Antarctic ice sheet is changing surprisingly quickly,” he said. Geologist Terry Wilson of Ohio State University;

“The rise of the Earth as a result of the decrease in ice on the surface occurs over decades, not thousands of years,” he added.

The team used 3D modeling to understand how sea levels will rise. Due to the change in land mass in Antarctica. “This study represents a revolution in our ability to better predict the impacts of climate change on sea level rise and guide effective environmental policies,” he said. Glaciologist Rob DeConto of the University of Massachusetts.

Since the Earth is not a smooth ball, Unique effects on sea level will be observed in different parts of our planet due to gravitational, rotational, and geological properties.

“Our results also support recent findings that low-latitude islands and coastal areas are already being affected by sea-level rise. You will see above-average sea level rise linked to the loss of Antarctic ice; “Regardless of the ice loss scenario,” Gomez and his team explained.
