UFRJ Study Reveals That Sea Could Advance Up to 100 Meters Over Iconic Beaches in Rio de Janeiro, Threatening Tourism and Mangroves
The beaches of Rio, including Copacabana, Ipanema, and Leblon, are among the most visited destinations in Brazil and attract tourists year-round. These stretches of sand boost tourism, the local economy, and help build the international image of Rio de Janeiro.
A recent study from the Federal University of Rio de Janeiro (UFRJ) has raised the alarm: much of these shorelines could disappear by the end of the century.
The projection indicates a concerning scenario for the city’s famous postcards.

The sea has stopped just warming and has started pushing storms towards the continent: marine heatwaves are already entering the path of up to 25% of extreme coastal rains and can increase storms by 30%, worsening floods on the coast.

Drone flies over indigenous area in Xingu and creates a point cloud capable of penetrating the tree canopy, revealing the forest floor, and mapping archaeological sites, ancient villages, roads, and ditches used to understand the historical occupation of the Kuikuro territory.

New technology may retire the common electric shower: Xiaomi introduces an intelligent model with tempered glass, a giant 305 mm spreader, antibacterial function, four water modes, and controls inspired by piano keys for around R$ 640 in China.

Japan surprises the world by launching a wooden satellite only 10 cm in size into space: the LignoSat project spent 240 days exposed on the ISS, withstood radiation, and could reduce space debris generated by metal structures.
Sea Advance Threatens the Carioca Shore
The research indicates that the sea level in Guanabara Bay could rise, on average, by 78 centimeters by 2100. This increase would be sufficient to drastically reduce the beach’s sandy area.
In Copacabana, the loss could reach 100 meters. Meanwhile, Ipanema and Leblon are at risk of shrinking by approximately 80 meters each.
These figures coincide with projections from the Intergovernmental Panel on Climate Change (IPCC), which predicts a global increase of between 28 and 98 centimeters.
Impacts Beyond Tourism
The problem is not limited to leisure and tourism. Mangrove areas also face risks. The Guapimirim Environmental Preservation Area, created to protect the last mangroves of Guanabara Bay, could be partially submerged.
According to experts, the situation may be even more serious than the calculations suggest since ocean warming has already outpaced historical averages.
Global Problem and Local Response
The phenomenon is not limited to Brazil. Regions such as Miami, Barcelona, and the Gold Coast in Australia are already suffering from beach reduction, in some cases losing up to 4.5 meters of sand per year.
The government of Rio claims to monitor climate effects and seeks adaptation strategies. Nonetheless, the UFRJ study makes it clear: without urgent actions, the beaches that today symbolize Rio may not exist for future generations.
