Metropolises in danger

A report from the investment bank Goldman Sachs claims that climate change is putting the world’s cities in danger.

According to the report, 55 percent of the global population – i.e. about 4.2 billion people – live in cities worldwide. The number of city dwellers is rising continuously: according to a UN estimate, 6.7 billion people will live in cities by 2050.

Due to their characteristics, cities are highly vulnerable in a number of ways: metropolises are usually warmer than the surrounding countryside; this results in more storms and more frequent rains, which doesn’t only make life more difficult for residents, it also often has a negative impact on economic processes.

According to Goldman Sachs,
not all cities are equally threatened,
and those that are also face diverse risks: New York, Tokyo and Lagos,
for instance, must face dangerous storms, while in Miami, Alexandria
and Dhaka, the main problem is
that they are less than 11 metres
above sea level.

Some cities (for instance New York and Manila) have already began to prepare for the worst due to recent disasters. The report continuously emphasises the importance of cooperation: they believe that international programmes and financing would be required, as climate change has no regard for national borders: global warming is a shared problem of all the planet’s residents.
