Big cities in Asia will be 'unprecedented extreme' weather

Researchers warn that by 2050, more than 20% of the world's major cities will face unprecedented extreme weather conditions, as rising temperatures increase the risk of flooding and drought.

Climate researchers at the Swiss Federal Institute of Technology analyzed data of 520 cities, including all capitals and most urban centers, with a population of over 1 million people.

According to Mr. Jean Francis-Bastin - the leader of the research team, the results show that by 2050, about 22% of the studied cities will be unprecedented with extreme weather such as the dry season and the rainy season.

Of these, 64% are cities located in the tropics , including Kuala Lumpur (Malaysia), Jakarta (Indonesia), Yangoon (Myanmar) and Singapore.

The climate in about 77% of cities in the study will also change significantly after 30 years, according to which climate conditions in many Northern Hemisphere cities may be similar in places more than 1,000km away. south towards the equator.

Tropical cities will have little change in average temperatures, but will change in rainfall, leading to severe flood or drought risks.

In Europe, the temperature in cities will increase by an average of about 2.5 degrees Celsius throughout the year, while summer and winter can increase by 3.5 degrees C and 4.7 degrees C, respectively.

Scientists believe that the study could help city governments adjust their plans, to prevent specific risks from climate change.

In addition, the study also contributes to pushing people around the world to change behaviors to reduce emissions causing global warming.
