Many coastal cities around the world are at high risk of flooding due to rising sea levels. In addition to flooding, they face other risks such as the complete disappearance of entire islands, loss of natural habitats, and damage to infrastructure.
We highlight two cities, Los Angeles and London, where the risk of flooding due to rising sea levels is very high. What will be done about it?
Sea level rise in coastal areas
The World Programme for Scientific Research and UNESCO have issued a warning to all coastal cities worldwide. The message is clear: rising sea levels caused by global warming pose a significant risk of wiping out coastal areas. The program began this Monday at Columbia University in New York.
"Future projections of sea level rise threaten the existence of many sovereign states and have implications for global migration, food security and coastal infrastructure," said the President of the UN General Assembly, Peter Thompson, in the opening of the congress.
The project, which studies regional variations in sea level and their potential impact on coastal cities, aims to provide coastal countries and communities with information about climate change and global warming. Understanding these impacts requires recognizing the threat and the environmental processes that cause sea level rise. This knowledge will enable populations to adapt to the effects of climate change and offer solutions.
Since the mid-20th century, sea levels have been rising considerably and at a fairly rapid rate as a consequence of global warming. This global warming is caused by greenhouse gas emissions resulting from human activity. In this sense, the effects of climate change in Spain are a clear example of the environmental crisis.
Many of the world's major cities and economic centers are located along coastlines. If sea levels continue to rise at this rate, the risk of flooding and the disappearance of these cities is quite high. London and Los Angeles are particularly susceptible to temporary and devastating damage from rising sea levels.
It is vital to understand and assess the impacts on cities in order to guide government adaptation at the regional level and implement measures to mitigate the problems. Furthermore, rising sea levels in London and Los Angeles require urgent initiatives to mitigate their effects. This includes understanding how global warming could affect beaches in Catalonia , a clear indication of the dangers we face in coastal regions.
