Global sea level rise is an emerging threat related to man-made climate change and greenhouse gas emissions. With this, a new study by British researchers looking at the rate of future cliff retreat has determined that sea level or sea-level rise will ultimately accelerate erosion of rocky coastlines.

A new study published in the journal Nature Communications On November 18, researchers at Imperial College London said the phenomenon of sea-level rise is likely to accelerate the rate of erosion of rocky coastlines or the retreat of rocky coastal cliffs, suggesting coastal risk to human-induced climate change. We stressed that response is paramount to residents and their infrastructure. in the disaster area.

The research team emphasized that the stability of rocky coasts has been largely neglected and that the expected acceleration of cliff erosion after sea-level rise has not been tested with empirical evidence so far.

The study reportedly agreed that rocky coasts, which make up more than half of the world’s coastlines, could retreat even more rapidly in the future. It is based on climate models for greenhouse gas emissions and climate change scenarios. Phys.org report.

This can put inland communities and habitats at risk of turbulent waters due to the disappearance or retreat of coastal rocks through erosion.

What is coastal erosion?

Coastal erosion, also called coastal erosion, American Geoscience Institute (AGI) As the process by which topography and coastlines are changed by a combination of currents, tides and waves.

The Institute says such erosion is a natural part of the rock cycle, and the coastal landforms we see today evolved naturally and geologically over millions of years. , anthropogenic climate change and global warming could cause global sea level rise and hasten erosion of rocky coasts.

of National Oceanic and Atmospheric Administration (NOAA) has published an assessment titled “2022 Sea Level Rise Technical Report” that provides the latest sea level rise projections for all US states and their territories. The result of a multi-agency collaboration and the first update since 2017, this report presents all U.S. coastal waters projects through 2150.

A NOAA report predicts that “sea level rise” along the US coastline over the next 30 years is projected to rise an average of 10 to 12 inches by 2050. land and sea level.

The technical report also notes that such rising water levels will cause more “damage” over the next 30 years by allowing tide levels and storm surges to increase in height and reach further inland in the United States. It is predicted that it will cause a “flood that gives By 2050, normal-to-moderate floods are expected to occur, on average, ten times more often than they do today.

The assessment also highlights that “greenhouse gas emissions” will pave the way for 2 feet of sea level rise along the US coastline by 2100. Sea levels will rise another 1.5 to 5 feet by the end of the century.
