and rising sea levels, driven by rising global temperatures, could result in the loss of almost 50% of the world’s sandy beaches by 2100, according to the study’s researchers at the European Union’s Joint Research Centre.
Scientists are hoping this new research serves as a “wake-up call,” Vousdoukas says. Nearly 40% of the erosion predicted “could be mitigated just by reducing greenhouse gas emissions” and also by employing better coastal management practices. Sea-level rise will vary across the globe, Vousdoukas says. Erosion will be greater depending on the type of terrain; the flatter the coastline, the more it is expected to recede.
“In Australia, we predict that there will be a lot of erosion in the north part of the continent where there is a lot of unoccupied land,” Vousdoukas says. “Our findings are more important for the south part, where you have most of the large cities.”“When you have an occupied coastline and you have a sandy beach, the system cannot retreat naturally and accommodate the new conditions,” he says.
